Do people tend to spend less when using cash than credit cards?
"I found the study ""The irrationality of payment behaviour"" accidentally while searching on the term ""DNB Study"" instead of ""D&B Study"".  This study, which, when I followed the link, went to the web site dnb.nl (Dutch National Bank), instead of dnb.com (Dun & Bradstreet).  It mentions all the salient points that I hear Dave Ramsey and others mention when they talk about studies on this subject of credit vs cash.  Also, it cross references to many other studies by various researchers, banks, and universities.  Is this the ""missing mythical DNB study?""  I'll let you decide.  Relevant ""coincidental"" points from the study: To be fair and complete, I should mention that clearly the relevant parts of this DNB study are talking about discretionary spending.  Auto-paying your mortgage with a card is clearly not going to cost you more (unless you somehow forget to pay off the card or some other silliness)." "I'd like to know if there is any reliable research on the subject. Intuitively, this must be true, no? Is it? First, is it even possible to discover the correlation, if one exists? Dave Ramsey is a proponent of ""Proven study that shows you will spend 10% more on a credit card than with cash."" Of course, he suggests that the study came from an otherwise reliable source, Dun & Bradstreet. A fellow blogger at Get Rich Slowly researched and found - Nobody I know has been able to track down this mythical Dun and   Bradstreet study. Even Dun and Bradstreet themselves have been unable   to locate it. GRS reader Nicole (with the assistance of her trusty   librarian Wendi) contacted the company and received this response:   “After doing some research with D&B, it turns out that someone made up   the statement, and also made up the part where D&B actually said   that.” In other words, the most cited study is a Myth.  In fact, there are studies which do conclude that card users spend more. I think that any study (on anything, not just this topic. Cigarette companies buy studies to show they don't cause cancer, Big Oil pays to disprove global warming, etc.) needs to be viewed with a critical eye. The studies I've seen nearly all contain one of 2 major flaws - My own observation - when I reviewed our budget over the course of a year, some of the largest charges include - I list the above, as these are items whose cost is pretty well fixed. We are not in the habit of ""going for a drive,"" gas is bought when we need it. All other items I consider fixed, in that the real choice is to pay with the card or check, unlike the items some claim can be inflated. These add to about 80% of the annual card use. I don't see it possible for card use to impact these items, and therefore the ""10% more"" warning is overreaching.  To conclude, I'll concede that even the pay-in-full group might not adhere to the food budget, and grab the $5 brownie near the checkout, or over tip on a restaurant meal. But those situations are not sufficient to assume that a responsible card user comes out behind over the year for having done so.  A selection of the Studies I am referencing -" Psychology Today had an interesting article from July 11, 2016, in which they go through the psychological aspects of using cash vs. a credit card. This article cites a 2008 paper in the Journal of Experimental Psychology: Applied that found: “the more transparent the payment outflow, the greater the aversion to spending or higher the ‘pain of paying’ …leading to less transparent payment modes such as credit cards and gift cards (vs. cash) being more easily spent or treated as play or ‘monopoly money.’” The article cites a number of other studies that are of interest on this topic as well. "Others have commented on the various studies. If, as JoeTaxpayer says, this one particular study he mentions does not really exist, there are plenty of others. (And in that case: Did someone blatantly lie to prove a bogus point? Or did someone just get the name of the organization that did the study wrong, like it was really somebody called ""B&D"", they read it as ""D&B"" because they'd heard of Dun & Bradstreet but not of whoever B&D is. Of course if they got the organization wrong maybe they got important details of the study wrong. Whatever.)  But let me add one logical point that I think is irrefutable: If you always buy with cash, there is no way that you can spend more than you have. When you run out of cash, you have no choice but to stop spending. But when you buy with a credit card, you can easily spend more than you have money in the bank to pay. Even if it is true that most credit card users are responsible, there will always be some who are not, and credit cards make it easy to get in trouble.  I speak from experience. I once learned that my wife had run up $20,000 in credit card debt without my knowledge. When she divorced me, I got stuck with the credit card debt. To this day I have no idea what she spent the money on. And I've known several people over the years who have gone bankrupt with credit card debt. Even if you're responsible, it's easy to lose track with credit cards. If you use cash, when you take out your wallet to buy something you can quickly see whether there's a lot of money left or not so much. With credit, you can forget that you made the big purchase. More likely, you can fail to add up the modest purchases. It's easy to say, ""Oh, that's just $100, I can cover that."" But then there's $100 here and $100 there and it can add up. (Or depending on your income level, maybe it's $10 here and $10 there and it's out of hand, or maybe it's $10,000.) It's easier today when you can go on-line and check the balance on your credit card. But even at that, well just this past month when I got one bill I was surprised at how big it was. I went through the items and they were all legitimate, they just ... added up. Don't cry for me, I could afford it. But I had failed to pay attention to what I was spending and I let things get a little out of hand. I'm a pretty responsible person and I don't do that often. I can easily imagine someone paying less attention and getting into serious trouble." "First, let me answer the question the best way I can: I don't know if there are any studies other than those that have already been mentioned. Now, let's talk about something more interesting: You don't need to base your behavior on any study, even if it is scientific. Let's pretend, for example, that we could find a scientifically valid study that shows that people spend 25% more when using a credit card than they do when spending cash.  This does not mean that if you use a credit card, you will spend 25% more.  All it means is that the average person spending with a credit card spends more than the average person paying cash.  But there are outliers.  There are plenty of people who are being frugal while using a credit card, and there are others who spend too much cash.  Everyone's situation is different.  The idea that you will automatically spend less by using cash would not be proven by such a study. When hearing any type of advice like this, you need to look at your own situation and see if it applies to your own life.  And that is what people are doing with the anecdotal comments.  Some say, ""Yep, I spend too much if I use a card."" Others say, ""Actually, I find that when I have cash in my wallet, I spend it on junk.""  And both are correct.  It doesn't matter what the study says the average person does, because you are not average. Now, let's say that you are a financial counselor who helps people work through disastrous financial messes.  Your client has $20,000 in credit card debt and is having trouble paying all his bills.  He doesn't have a budget and never uses cash.  Probably the best advice for this guy is to stop using his card and start paying cash.  It doesn't take a scientific study to see that this guy needs to change his behavior. For what it is worth, I keep a strict budget, keeping track of my spending on the computer.  The vast majority of my spending is electronic.  I find tracking my cash spending difficult, and sometimes I find that when I have cash in my wallet, it seems to disappear without a trace.  :)" I don't think that there is any good way a study can average this and bring a useful result: The core problem is that there are people that will spend more money than they should, if they become technically able to, and the credit card is just one of the tools they abuse for that (similar to re-financing with cash-outs, zero percent loans, etc.).  On the other side, there are people who control and understand their spending, and again, the mechanism of payment is irrelevant for them. Studies measure some mix between the groups, and come up with irrelevant correlations that have no causality. If you think any tool or mechanics got you in financial trouble, think again: your spending habits and lack of understanding or care get you in financial trouble - nothing else. In a world where it is considered cool to 'don't understand math', it is no surprise that so many people can't control their finances. "I thought I'd see if the credit card companies had anything to say about this while trying to get merchants to sign up. I went to visa.com, clicked ""Run Your Business"" in the top nav, then ""Accept Visa Payments"". This page has a ""More benefits of accepting Visa"" link with an overlay (which I can't easily link directly to), which includes these lines: While the average cash transaction is $17, credit card purchases average $70 while debit card purchases average $36.² ² Visa Payment Panel Study (2Q11 to 1Q12 time period); Visa MARS Data: March 2015 – May 2015  That obviously doesn't tell the entire story (I suspect people are more likely to pull out cash when they're just buying a stick of gum, and more more likely to pull out a card when they're buying large electronics), but certainly there is some evidence from the credit card companies themselves that people spend more when using cards, which is one of the aspects they use to convince merchants to accept cards. I think the best evidence that people spend more is that more and more merchants accept cards. Accepting cards comes with some significant costs (though it's important to keep in mind that accepting cash can come with some significant costs as well). I suspect that merchants wouldn't do so unless the increased sales that they get for accepting cards makes up for the fees that they need to pay and the equipment they need to buy to accept them (not to mention the risks of chargebacks and the like)." Unless a study accounts for whether the users are following a budget or not, it is irrelevant to those who are trying to take their personal finances seriously. I can certainly believe that those who have no budget will spend more on a credit card than they will on a debit card or with cash. Under the right circumstances spending with cards can actually be a tool to track and reduce spending. If you can see on a monthly and yearly basis where all of your money was spent, you have the information to make decisions about the small expenses that add up as well as the obvious large expenses.  Debit cards and credit cards offer the same advantage of giving you an electronic record of all of your transactions, but debit cards do not come with the same fraud protection that credit cards have, so I (and many people like me) prefer to use credit cards for security reasons alone. Cash back and other rewards points bolster the case for credit cards over debit cards. It is very possible to track all of your spending with cash, but it is also more work. The frustration of accounting for bad transcriptions and rechecking every transaction multiple times is worth discussing too (as a reason that people get discouraged and give up on budgeting). My point is simply that credit cards and the electronic records that they generate can greatly simplify the process of tracking your spending. I doubt any study out there accounts for the people who are specifically using those benefits and what effect it has on their spending. "One study found that, while people using gift certificates bought no more items than those who used cash, they tended to spend more per item. In ""Study 3"" the paper ""Monopoly money: The effect of payment coupling and form on spending behavior"", sets up a case where shoppers are given $50 in cash and $50 in gift certificates (the leftover of which can be exchanged for cash). They were asked to choose different brands and types of items to buy. They study found that There was no difference in the number of items purchased as a   function of payment form for scrip However means across all product categories show that   participants spent more per item when they were given [the gift certificate]"
"This may be a bit advanced now, but once you start really working and get a place, I think this will apply more... Do I set up a bank account now? Yes. There is no reason not to. As an adult you will be using this much more than you think.  Assuming you have a little money, you can walk in to any bank almost any day of the week and set up an account with them in very little time. Note that they may require you to be 18 if your parents won't be with you on the account. Otherwise, just ask any bank representative to help you do this. Just to be clear, if you can get a credit union account over a typical bank account, this is a great idea. Credit unions provide exactly the same financial services as a normal bank, but typically have variety of advantages over banks.   Bank Account Parts Bank accounts typically have two parts, a checking account and a savings account. Your checking account typically is what you use for most day-to-day transactions and your savings account is generally used for, well, saving money.  Having a bank account often gives you the following advantages: They give you an ability to store money without having large amounts of cash on hand. Once you start working regularly, you'll find you won't want to keep ~$600+ cash every two weeks in your wallet or apartment. They help you pay bills. When you set up your bank account, you will likely be able to get a Visa debit card which will process like a regular credit card but simply deduct funds from your checking account. You can use this card online to pay utilities (i.e. electricity and water), general bills (e.g. your cell phone and cable), purchase items (ex. at Amazon) or use it in stores to pay in lieu of cash.  Be aware -- some banks will give you an ATM-only card before they send you the Visa debit card in the mail. This ATM-only card can only be used at ATMs as it's name implies.  Similarly, if you can invest about ~$200 to build your credit, you can often get a deposit secured credit card attached to your account (basically a credit card where the bank keeps your money in case you can't pay your bill). If you treat this card with responsibility, you can eventually transition to an unsecured credit card. They save you hassles when cashing your check. If you don't have a bank where you can cash your check (e.g. you don't have an account), you will likely be charged check cashing fees (usually by places such as grocery stores or payday loan chains, or even other banks). Furthermore, if your check is over a certain amount, some places may refuse to cash your check period and a bank may be your only option. They give you a way to receive money electronically. The most common example of this is direct deposit. Many employers will send your money directly to your bank account instead of requiring you to cash a check. If they are prompt, this money gets to you faster and saves you trouble (on payday, you'll just receive a pay stub detailing your wages and the amount deposited rather than a check).  Also, since you asked about taxes, you should know that when you do eventually file with the IRS, they have an option to receive your tax refund electronically as well (e.g. direct deposit into your bank account) and that can literally save you months in some cases depending on when you file your return and how many paper checks they have to process. Does it cost money to setup? It depends. Some banks have special offers, some don't. Most places will set up an account for free, but may require a minimum deposit to open the account (typically $50-$100). The Visa debit card mentioned above generally comes free. If you want a secured credit card as above, you will want about an additional $200 (so $250 - $300 total). Note that this is absolutely NOT required. You can exclusively use the Visa debit card above if you wish. Bank Account Fees Any fees charged when you have a bank account are usually minor anymore. Regardless, the bank will hand you a whole bunch of paperwork (mostly in legalese) detailing exactly how your account works. That said, the bank person helping set things up will cover what you need to know about keeping the account in plain English. The most common types of fee associated with a bank account are monthly maintenance fees and overdraft fees, but these aren't always necessarily charged. Likewise, there may be some other fees associated with the account but these vary from bank to bank.  Monthly Maintenance Fees To give some examples... Overdraft Fees Overdraft fees are typically charged when you attempt to spend more money than you have in your bank account and the bank has to cover these charges. Overdraft fees typically apply to using paper checks (which it is unlikely you will be using), but not always.  That said, it is very unlikely you will be charged overdraft fees for three reasons: Many banks have done away with these fees in lieu of other ways of generating revenue.    Banks that still charge these fees usually have ""overdraft protection"" options for a little more money a month, effectively negating the possibility you will be charged these fees.  The ability to deduct an amount of money from your checking account is now typically checked electronically before the payment is authorized. That is, using a Visa debit card, the card balance is checked immediately, and even when using paper check, most retailers have check scanning machines that do roughly the same thing. On a personal note, the bank that I have allows my account to be deducted below my checking account balance only if the payment is requested electronically (e.g. someone who has my card information charges me for a monthly service). In this case, the funds are simply listed in the negative and deducted from any amount I deposit till the proper amount is repaid (e.g. if I'm at -$25 dollars due to a charge when my account balance was $0 and then I deposit $100, my available balance will then be $75, not $100). Finally, per the comment by @Thebluefish, while I minimize the likelihood you will be charged overdraft fees, it is good to check into the exact circumstances under which you might be charged unexpectedly by your bank. Read the documentation they give you carefully, including any mailed updates, and you'll reduce the chance of receiving a nasty surprise. For reference, here are some of the fees charged by Bank of America. What about taxes? When you begin working, an employer will usually have you fill out a tax form such as a W-4 Employee's Withholding Allowance Certificate so that your employer can withhold the correct federal income tax from your wages. If they don't, then it is your responsibility to calculate and file your own income taxes (if you are self-employed, an independent contractor or paid under the table).  If your employer is reputable, they will send you additional information (generally in February) you need to properly file your taxes prior to April 15th (the IRS tax deadline for most people). This additional information will likely be some variation of a W-2 Wage and Tax Statement or possibly a Form 1099-MISC.  Do I have to worry about money in my bank account? Unless you have a significant amount in your bank savings account earning interest (see ""Should I save for the future?"" below), you won't have to pay any sort of tax on money in your bank account. If you do earn enough taxable interest, the bank will send you the proper forms to file your taxes. How do I file taxes? While it won't apply till next year, you will likely be able to fill out a Form 1040EZ Income Tax Return for Single and Joint Filers With No Dependents, as long as you don't have any kids in the meantime. ;-) You will either mail in the paper form (available at your local IRS office, post office, public library, etc.) or file electronically. There will be a lot of information on how to do this when the time comes, so don't worry about details just yet.  Assuming your all paid up on your taxes (very likely unless you get a good paying job and take a lot of deductions throughout the year on your W-4), you'll probably get money back from the IRS when you file your tax return. As I mentioned above, if you have a bank account, you can opt to have your refund money returned electronically and get it much sooner than if you didn't have a bank account (again, possibly saving you literal months of waiting). Should I save for my future? If so, how much? Any good articles? Yes, you should save for the future, and start as soon as possible. It's outside the scope of this answer, but listen to your Economics professor talk about compound interest. In short, the later you start saving, the less money you have when you retire.  Not that it makes much difference now, but you have to think that over 45 years of working (age 20-65), you likely have to have enough money for another 20+ years of not working (65-85+). So if you want $25,000 a year for retirement, you need to make ~$50,000 - $75,000 a year between your job and any financial instruments you have (savings account, stocks, bonds, CDs, mutual funds, IRAs, job retirement benefits, etc.) Where you should stick money your money is a complicated question which you can investigate at length as you get older. Personally, though, I would recommend some combination of IRA (Individual Retirement Account), long term mutual funds, and some sort of savings bonds. There is a metric ton of information regarding financial planning, but you can always read something like Investing For Dummies or you can try the Motley Fool's How To Invest (online and highly recommended). But I'm Only 17... So what should you do now? Budget. Sounds dumb, but just look at your basic expenses and total them all up (rent, utilities, phone, cable, food, gas, other costs) and divide by two. Out of each paycheck, this is how much money you need to save not to go into debt.  Try to save a little each month. $50 - $100 a month is a good starting amount if you can swing it. You can always try to save more later. Invest early. You may not get great returns, but you don't need much money to start investing. Often you can get started with as little as $20 - $100. You'll have to do research but it is possible. Put money in your savings account. Checking accounts do not typically earn interest but money in savings accounts often do (that is, the bank will actually add money to your savings assuming you leave it in there long enough). Unfortunately, this rate of interest is only about 3.5% on average, which for most people means they don't get rich off it. You have to have a significant amount of money ($5,000+) to see even modest improvements in your savings account balance each month. But still, you may eventually get there. Get into the habit of putting money places that make you money in the long run. Don't go into debt. Don't get payday loans, pawn items, or abuse credit cards. Besides wrecking your credit, even a small amount of debt ($500+) can be very hard to break out of if you don't have a great paying job and can even make you homeless (no rent means no apartment).  Remember, be financially responsible -- but assuming your parents aren't totally tight with money, don't be afraid to ask for cash when you really need it. This is a much better option than borrowing from some place that charges outrageous interest or making your payments late. Have an emergency account. As already mentioned in another excellent answer, you need to have money to ""smooth things out"" when you encounter unexpected events (your employer has trouble with your check, you have to pay for some sort of repair bill, you use more gas in your car in a month than normal, etc.) Anywhere from $200 - $2000+ should do it, but ideally you should have at least enough to cover a month of basic expenses. Build good credit. Avoid the temptation to get a lot of credit cards, even if stores and banks are dying to give them to you. You really only need one to build good credit (preferably a secured one from your bank, as mentioned above). Never charge more than you can pay off in a single month. Charging, then paying that amount off before the due date on your next statement, will help your credit immensely. Likewise, pay attention to your rent, utilities and monthly services (cell phone, cable, etc.). Even though these seem like options you can put off (""Oh my electric bill is only $40? I'll pay that next month..."") late payments on all of these can negatively affect your credit score, which you will need later to get good loans and buy a house.  Get health insurance. Now that the Affordable Care Act (ACA a.k.a Obamacare) has been enacted, it is now simpler to get health insurance, and it is actually required you have some. Hopefully, your employer will offer health coverage, you can find reasonably priced coverage on your own, or you live in a state with a health exchange. Even if you can't otherwise get/afford insurance, you may qualify for some sort of state coverage depending on income. If you don't have some sort of health insurance (private or otherwise), the IRS can potentially fine you when you file your taxes. Not to be too scary, but the fine as currently proposed is jumping up to about $700 for individuals in 2016 or so. So... even if you don't grab health insurance (which you absolutely should), you need to save about $60 a month, even if just for the fine.  This answer turned out a bit longer than intended, but hopefully it will help you a little bit. Welcome to the wonderful world of adult financial responsibility. :-)" "The most likely reason for this card is that Amazon has an arrangement with the issuer (I believe that that used to be Chase; may have changed since).  Such an arrangement may allow Amazon to take the risk of chargebacks, etc. in return for the issuer handling the mechanics of billing.  This is advantageous for Amazon, as otherwise they are subject to both their own procedures and those of the issuer.  Amazon would rather take the entire risk than share it with someone else who charges for the privilege.   Fees for processing credit cards can be as much as 5%, although 1-2% is more typical.  Due to its size, Amazon may already have negotiated fees lower than 1%.  But even so, any savings they make are to their benefit.  Further, now they can get a share of the fees charged to other merchants.  For example, if you buy a book from Barnes & Noble (an Amazon competitor) with the Amazon card, then Amazon gets some money in return, say 1% of the transaction.   If the price is the same on Amazon and at Barnes & Noble, you can actually save money with the Amazon card.  Amazon gives more ""cash back"" in the form of gift card balance for an Amazon purchase.  So the card may mean that you buy from Amazon when you might otherwise have chosen someone else.  If we again assume a 20% margin, they only need $200 of additional purchases to make $40 of profit.  Someone who buys $1000 additional on the Amazon site makes them $200 of profit.  They're over $160 ahead.   Also note that Amazon is only giving you a gift card, which you have to use on Amazon.  And it's difficult to spend exactly $50.  As a practical matter, most people will buy, say, $60, with $10 of that money.  So they sell you $48 of merchandise (their cost, assuming a 20% margin) for $10.  They lost $38 on that transaction, but they've lured you into a long term relationship that may return more than that.  And they didn't lose the $50 you gained.  They only lost $38.   Think about it as a marketing cost.  Amazon is willing to pay $38 for a long term relationship with you.  From their perspective, doing so in such a way that you come out $50 ahead (assuming you would have made the same purchases without this), is a win-win.  Because once they have that relationship, they can leverage it to give them savings elsewhere.   This is Amazon's approach in general.  Originally all their products were drop shipped (from someone like Ingram Micro).  They handled the web site and billing while the drop shipper handled inventory and shipping.  Then Amazon added their own warehouses.  Now they can do all that separately.   This is just the same thing for buyers.  Amazon manages all the risk of the transaction and thus gets all the profit.  Because Amazon is managing the credit card risk, they have access to all the credit history.  This helps them better determine if that sudden shipment of a $2000 camera to Thailand is a real transaction (you're a photographer who regularly vacations in Thailand) or a fake (you've never been to Thailand in your life and your phone is camera enough).  That additional information may itself be worth enough to make the relationship profitable for Amazon.   Amazon certainly gets something out of the relationship.  You give them money.  And you are likely to give them more money with the Amazon card than they would otherwise receive.  But you get products in return.  Is that a good deal?  If you prefer having the products to the money, then yes.   Others have suggested that it's the irresponsible credit card users that generate the real profit.  I disagree.  They generate more revenue in the short term, but then they overspend and declare bankruptcy.  Then Amazon loses its money.  Yes, they get more interest and fees in that case, but if they lose $1000, they needed to make $1000 in profit just to break even.  It's safer to make the smaller short term profits with responsible customers who will continue to be customers for the long term.   A steady profit of $100 or $200 a year is better than a one time profit of $500 followed by a loss of $1000 followed by nothing for ten years.   Anyway, your question was if you should sign up for the card.  If you are planning on doing a lot of shopping on Amazon, you might as well.  It gives you cash back.  If shopping on Amazon is inconvenient, then perhaps that outweighs the advantage of the card.  The ""cash back"" is just Amazon money.  You can't spend it anywhere but Amazon.  If each transaction gives you a little bit of Amazon money, you have to keep going back to spend it." If you keep going over budget with your credit card, then stop using the credit card. If you plan to pay off the card every month, then your balance should always be under whatever your budget is.  For example, if you budget to spend $500, then even though your card has a limit of $5,000 you will never carry a balance of over $500.  Most banks have an option to email and / or text message you when you pass a certain balance threshold; in this instance, you would set two notices, one when your balance exceeds $400 (warning you that you're close & need to start paying closer attention), and one when you exceed $500. Additionally, maybe you aren't ready to pay for everything with your credit card.  I prefer to use mine just for groceries, and then pay it off at the end of the month.  Whatever rewards you get for putting all of your purchases on the card are more than paid for when you cross your budget limit, costing you more in interest and fees.  Perhaps starting with just one type of purchase (groceries or gas are good choices, as most consumers are fairly consistent in their purchases of both) would allow you to ease into using the card until you get used to managing your budget with it. Personal finances are all about behavior, not knowledge.  Don't worry too much about slipping up right now and making a mistake; just keep practicing good behavior with your credit card, and soon managing your budget with it will be as natural for you as when you only used cash. Correct. By putting expenses on to a credit card which does not charge interest during the grace period, and paying that balance every month, in effect you earn interest on money you've already spent. However, first, savings account interest is something like .05% right now depending on your bank. Yeah it's money, but seriously, that's 4 cents per month on $1000.  Second, two things can make this very wrong. If you carry a balance, you'll pay much more in interest than you'd get from practically any investment you could make with the cash in the meantime. Second, a debit card can be used to get cash you already have from an ATM (not everyone takes credit, you know), and it'll cost you little or nothing. Use a credit card for the same purpose and you're paying 40% from the second the money comes out of the machine. Also correct. Rewards cards earn you more the more they're used. That's because the card issuer makes money based on usage; they get 3% of each transaction. They're happy to turn 1% of that, up to a limit or subject to a spending floor, back around to you. Again, check the terms and conditions. Most cards have a limit on total rewards. Many of them also have fees, either while you hold the card or when you try to redeem the rewards. Look for a card with high limits or no limits on rewards from spending, and with no annual fee or reward redemption fee. In addition to the above, you build good credit history with good spending patterns. However, your credit score can fluctuate wildly, because on one day you have very low leverage (percent of credit limit used), and on the next you've bought $200 in groceries and so your leverage went up 20% on a card with a $1000 limit. Leverage under 10% is good, leverage under 40% is OK and leverage over that starts looking bad. With a $1000 limit, with you maxing it out and then paying it off, your credit score can fluctuate by 30 points on any given day. The cost to the store is small. They may have to pay a slightly greater fee because the transaction is now bigger. They do need additional cash on hand. Even though the majority of transactions are electronic (credit/debit) or check, the local grocery store still seems to have significant cash on hand. This is seen as a customer service. If there is a 2% fee the $50 advance costs them $1 for the minority of customers that take advantage of it. After more than 10 years of doing this they have figured this into the cost of groceries. Of course the credit card company could also waive the fee to store. My credit card online statement does tell me how much cash back was received. The line says date, store, amount ($40.00 cash over and $123.45 purchases) $163.45 total. Therefore the credit card company knows that cash back was used. "People should borrow and spend less, and save more.  Is this truly correct? Isn't the fundamental problem high supply and no demand?  Shouldn't it be ""borrow less but spend more"" - which of course would mean getting higher wages.  Am I wrong? Please to be educating." "You don't need to have a bunch of credit cards lying around; just a couple is fine. Get a ""rewards"" card (without annual fee) that pays you back for use, and use it regularly to buy groceries, for example. Pay it off promptly each month, using the rewards, if you like, to reduce the amount you have to send in. Or you can use the rewards for other purchases; some merchants offer $25 worth of merchandise for $20 in rewards. It used to be the case that you could negotiate a discount for paying cash rather than use a credit card, but that is a lot harder to do now, in many cases because credit-card company contracts with merchants prohibit this practice. Also, merchants often prefer credit cards rather than cash because money-handling is an issue (pay for an armored car to come pick up the day's receipts, or risk getting mugged on the way to the bank, possible burglaries if you leave the money overnight in the store, daily balancing of cash-register trays, etc.) So, not being in debt and being rich enough to not need to be in debt are laudable goals, and you have my best wishes that you will reach them soon, but getting rid of all your credit cards as a part of not being in debt may be more trouble than it is worth. Keep a couple, pay them off promptly, and if you are concerned about being in debt, you can time your charges so that you are in debt at  most 2 or 3 days each month." You don't need a credit card anymore than you need a TV or a car.  There might be many circumstances where a credit card is a convenience, there might be things you give up because you don't have a credit card.  There are even some upsides to a well managed card account. But no, you don't need it.
