Why do cash back credit cards give a higher rate for dining and gasoline purchases?
These two categories ensure you will carry the card in your wallet (since they only work for physical locations), but don't tend to have excessive spending (most people maxing out at $200 or so per month, so $2 for the bonus).  You then use the same card for other purchases, because you have it on you, where you only get the 1%. It worked for me, I started carrying the Amazon card when I found out it had a higher percentage for gas purchases.  I only use it for gas though. I am not sure but probably it depends upon the cut the credit card company receives from the merchant. For Hotels such as dining etc. the cut could be more. Again, periodically, many merchants join with the card company to launch promotions. It could be part of such promotions. Apart from class of merchants, these points also differ on class of cards e.g a premium card will earn more rewards than a simple classic card. Don't really know but I can guess. Firstly, everyone thinks the price of gas is too high. You drive to work every day, and gas is basically the only product who's price is advertised from the street! From that perspective. So mentally, I argue, we overvalue an extra 1 percent discount on gas. It's only worth maybe 60 cents a month to me, but worth a lot of other interchance fees for the credit card company. Secondly, gas stations are a prime robbery target. Credit cards mean less cash in the till. And less chance for employees to steal from the till, and less chance of counterfit money. Finally, it's a competitive market. If stations don't accept a card, they'll lose business to elsewhere. There's a gas station on either side of an intersection, and you can always tell which station is a few cents cheaper because it's the one with customers fueling up while the other one is a ghost town. They feel they have to compete on convenience or go under, and the credit card companies recruit you into the game with higher cash back rewards.
"I would recommend putting it on a credit card, just not your current credit card. Run a Google search for ""credit cards with good signup bonuses"" and you will potentially come across these links: http://www.cardrates.com/advice/11-best-signup-bonus-credit-cards/ https://www.nerdwallet.com/blog/top-credit-cards/best-credit-card-offers/ There are cards out there which can qualify you to: The $150 back on a $500 purchase is an instant 30% ROI. The best stock options couldn't guarantee you that kind of return. You will instantly meet the criteria and get $150 + $25 (1% cash back on the full $2,500) The only stipulation is that in order to fully benefit from the rewards, you must pay off the card in full when your bill comes in or else you will pay steep interest. After a year or so you can cancel the card. If you want, sign up for two or three cards and split the payment. Reap the rewards from multiple credit cards. I wish I had done this with my college tuition; it was a tough pill to swallow when I forked over $3,000 at the registrar's office for one semester :-( I had the potential to realize a savings of $900 in one semester alone. Would have been nice to apply such a kickback against buying my books. If you work things out correctly then you can save 30% ($750) on your total purchase. That's one way to not run yourself dry. Disclaimer: By following these steps you will be triggering at least one hard inquiry against your credit. Each hard inquiry has the potential to lower your credit rating. If you do not plan to use your score to apply for any major loans (e.g. car or house) then this reduction in credit will have basically no impact on your day-to-day life. Assuming you continue using your credit responsibly then your credit should just bounce right back to where it was in no time. I know there are many people out there that cherish their score and relish in the fact that it is so high but it's for moments like these that make it worthwhile to ""spend"" your credit score. It's an inanimate number whose sole purpose is to be ""spent"" in times like these." Everyone else seems to have focused (rightly so) on the negatives of credit cards (high interest rates) and why it is important to pay them off before interest starts accruing. Only Marin's answer briefly touched on rewards.  To me, this is the real purpose of credit cards in today's age.  Most good rewards cards can get you anywhere from 1-2% cash back on ALL purchases, and sometimes more on other categories.  Again, assuming you can pay the balance in full each month, and you are good at budgeting money, using a credit card is an easy way to basically discount 1-2% of all of the spending you put on your card.  AGAIN - this only works to your advantage if you pay off the credit card in full; using the above example of 20% interest, that's about 1.6% interest if the interest compounds monthly, which wipes out your return on rewards if you just go one month without paying off the balance. I'm an Australian who just got back from a trip to Malaysia for two weeks over the New Year, so this feels a bit like dejavu! I set up a 28 Degrees credit card (my first ever!) because of their low exchange rate and lack of fees on credit card transactions. People say it's the best card for travel and I was ready for it. However, since Malaysia is largely a cash economy (especially in the non-city areas), I found myself mostly just withdrawing money from my credit card and thus getting hit with a cash advance fee ($4) and instant application of the high interest rate (22%) on the money. Since I was there already and had no other alternatives, I made five withdrawals over the two weeks and ended up paying about $21 in fees. Not great! But last time I travelled I had a Commonwealth Bank Travel Money Card (not a great idea), and if I'd used that instead on this trip and given up fees for a higher exchange rate, I would have been charged an extra $60! Presumably my Commonwealth debit card would have been the same. This isn't even including mandatory ATM fees. If I've learned anything from this experience and these envelope calculations I'm doing now, it's these: I don't agree with others regarding paying off debt ASAP. You only have auto loan and auto loans are actually good for your credit score. With a mere $6k balance, it is not like you are going to have a problem paying off the loan. Not only that you will build your credit score and this will come in handy when you are purchasing a home.  With the Federal Reserve setting the interest rate at 0% until 2015, I can't understand why people would pay off anything ASAP. As long as you don't have revolving credit card balances, you are in the clear. I don't know your salary nor how big your porfolio is but I would save 5 months expense in cash and dump the rest in precious metals. Holding cash is the worst thing you could be doing (unless you predict a deflation).  You said you already have 40% in precious metals. You are already way ahead of other 95% of  Americans by protecting your purchasing power. Follow your gut. The stormg is coming and it's not going to get any better. I'm surprised by all the pro-credit answers here, debit has some definite advantages. Most importantly, when you pay with a credit card, the merchant pays around 3% of the transaction to the credit company. In many states, they are forced to charge you the same amount, and this is frequently toted as ''consumer protection''. But consider what this means for the business: they loose money for every credit transaction, and they're legally forbidden to do anything about it. So you're taking 3% from a business and handing it over to a massive cooperation.  To make matters worse, the buisness is inevitably going to have to raise their prices (albiet by a small amount), so in the end the average consumer has gained nothing. On the other hand, the credit card company wins big, and they use their profits to pay lobbyists and lawyers to keep these rules in place. To put in the worst possible light, it's essentially legal extortion, verging on corruption. As for the fraud protection offered, while it may be true that credit cards will offer a more hassle-free reimbursement (i.e. you just don't have to pay the bill) if your card is stolen, consumer protection laws also extend to debit: in many cases your bank is legally required to cut you a check for all the money you lost. "Credit cards have three important advantages. None of them are for day-to-day borrowing of money. Safety - Credit cards have better fraud protection than checks or cash, and better than most debit/check cards. If you buy something with a credit card, you also get the issuer's (think Visa) assurances that your will get the product you paid for, or your money back. At almost any time, if a product you buy is not what you expect, you can work with the issuer, even if the store says ""screw you"". Security - Credit cards are almost universally accepted as a ""security"" against damages to the vendor. Hotels, car rentals, boat rentals etc. will accept a credit card as a means of securing their interests. Without that, you may have to make huge deposits, or not be able to rent at all. For example, in my area (touristy) you can not rent a car on debit or cash. You must use a credit card. Around here most hotel rooms require a credit card as well. This is different from area to area, but credit cards are nearly universally accepted. Emergencies - If you're using your credit card properly, then you have some extra padding when stuff goes wrong. For example, it may be cheaper to place a bill on a credit card for a couple months while you recover from a car accident, than to deplete your bank account and have to pay fees. Bonus - Some cards have perks, like miles, points, or cash back. Some can be very beneficial. You need to be careful about the rules with these bonuses. For example, some cards only give you points if you carry a balance. Some only give miles if you shop at certain stores. But if you have a good one, these can be pretty fantastic. A 3% cash back on purchases can make a large difference over time." One things about psychology - people spend more money when its an abstract concept instead of having cold, hard cash. What does this mean? People spend more money when they use credit cards for day to day purchases. While I still use a credit card for day to day purchases, there's a big difference between bringing $200 to costco to pay for groceries and laying out 10 $20 bills vs swiping a card when you see a number flash on the screen. If you're truly looking to reduce expenses, keep this in mind. "When you buy something with your credit card, the store pays a fee to the credit card company, typically a base fee of 15 to 50 cents plus 2 to 3% of the purchase. At least, that's what it was a few years back when I had a tiny business and I wanted to accept credit cards. Big chain stores pay less because they are ""buying in bulk"" and have negotiating power. Just because you aren't paying interest doesn't mean the credit card company isn't making money off of you. In fact if you pay your monthly bill promptly, they're probably making MORE off of you, because they're collecting 2 or 3% for a month or less, instead of the 1 to 2% per month that they can charge in interest. The only situation I know where you can get money from a credit card company for free is when they offer ""convenience checks"" or a balance transfer with no up-front fee. I get such an offer every now and then. I presume the credit card company does that for the same reason that stores give out free samples: they hope that if you try the card, you'll continue using it. To them, it's a marketing cost, no different than the cost of putting an ad on television."
