How much (paper) cash should I keep on hand for an emergency?
"Coming from an area that is hurricane prone, and seeing what happens to local businesses during evacuations/power outages/gas shortages, I think what you already have on hand should be sufficient. And it sounds like that's exactly what you're budgeting for.  I'd say 2 weeks worth of fuel and food costs, with the budget for each in line with riding out a natural disaster. True ""Preppers"" would say keep your money in gold buried in the backyard surrounded by land mines, but that's not perhaps what you're looking for. It is not uncommon for gas stations and grocery stores to revert to cash only sales, especially if they're not big chain operations. If the internet is out, or power is spotty, they may not be able to process CCs. Again, think smaller or more rural businesses. I have seen gas stations switch to cash only during gas shortages as well to help limit how much fuel people were buying.  $250 should get you through fine unless you drive a tank and need steak every night. You could probably go with less, but it's entirely dependent on your needs. As Joe rightly stated in his answer, if it's desperate enough times that you can't use a CC or debit card, cash may not even be useful to you." "It's also worth thinking about minor ""emergencies"" when the location of your cash may be more important than the amount. I keep a baggie of change and small bills in my glovebox for meters and tolls. I keep a ten dollar bill in my armband when I go out for a jog or bike. Those little stashes have saved me more than once. Zombie apocalypse money? I just have a couple hundred at home." No cash is necessary for most people.  In the modern day in the US there is no need to keep paper currency around for emergencies; any sort of emergency that knocked out all of the ability to use plastic (ATMs, credit cards, etc.) for an extended period of time AND knocked your bank out of service would be of the level that cash  might not have any value either. Your $100 of cash for natural disasters is likely more than enough, and even that I wouldn't necessarily consider a vital thing in this day where even a major natural disaster probably isn't going to have too much impact on the financial sector outside of the immediate area (that you should be exiting quickly).  Keep however much cash around that you need for day to day cash expenses, and that should be enough. The level of emergency that would suggest cash being needed would probably need more than you'd actually want to keep around, anyway - i.e., a complete collapse of the American or World financial system would imply you need months' worth of cash.  That's just not feasible, nor is it practical financially.  You should have your emergency fund making at least a bit of interest - 1% or so isn't hard to get right now, and in the near future that may increase substantially if interest rates go up. It also would make you a substantial theft target if it were known you had months' worth of cash around the house (i.e., thousands of dollars).  Safes don't necessarily give you sufficient protection unless you've got a very good safe - commercial ones are only as safe as the ability to crack them and/or transport them is. Now, if you find yourself regularly out at 2am and run out of cash, and you live somewhere that ATMs don't exist, and you find yourself needing to pay cab drivers from time to time after a drunk bender... then I'd keep at least one cab's worth of cash at home.
I hate to sound harsh, but he's right. No technology, innovation, service or product can overcome your own lack of discipline. That doesn't mean you should give up, though - just like everything else, financial discipline is a learned skill, not something we're born with.  Everyone can learn to be financially responsible. If you find you can't keep track of your expenses, try merely saving your receipts.  Whenever you get home, pull them all out of your pockets, and look over how much you spent.  Once you get to the point where you're consistently keeping your receipts, start keeping a register (either paper or electronic) that you update when you empty your pockets.  From there, you can begin tracking how much you spend in various categories, and being setting budgets and adjusting your spending habits. It's not easy, but it's something that we all have gone through.  Keep at it, and you can succeed in turning your finances around. "It is going to save you more money in the long run to pay at once with cash. If you take out a loan, you will pay interest on the balance, costing you money. If you pay off the balance immediately, there is no difference between the options and your question becomes irrelevant.  There is no credit rating benefit to placing large purchases on your cards, especially since your credit is fine. My advice is to pay in cash in this case, mostly because it makes you 'feel' the purchase. This is what you are describing in your question. This instinct helps you recognize potential problems, instead of masking them with debt. Questions like: ""Do I need this?""  ""Am I overextending myself financially with this purchase?""  ""Am I holding enough cash-on-hand for emergencies?"" You may be fine in these areas, but I would still argue that cash makes you a better buyer because the expense feels much more significant, making you more cautious and discerning.  You are right to feel these things before dropping a large sum of money. Let it inform you and help you make better decisions. Don't mask it or be paralyzed by it!" How much should my down payment be? Ideally 20% of the purchase price because with 20% of the purchase price, you don't have to pay a costly private mortgage insurance (PMI).  If you don't have 20% down and come across a good property to purchase, it is still a good idea to go forward with purchasing with what you are comfortable with, because renting long term is generally never a good idea if you want to build wealth and become financially independent. How much should I keep in my emergency fund? People say 3-12 months of living expenses.  Keep in mind though, in most cases, if you lose your job, you are entitled to unemployment benefits from the government. How long should my mortgage be? 30 year amortization is the best. You can always opt to pay more each month.  But having that leverage with a 30 year loan can allow you to invest your savings in other opportunities, which can yield more than mortgage interest. Best of luck! "I suppose this could really depend on the part of the world you're in, but there are still many instances of ""emergencies"" that need ""cash"". You have to decide how much cash is the right amount, but I still recommend having $1,000 or so in liquid cash. It can really make a huge difference. Let me give a few examples.  Bad weather. I live in Florida and after a hurricane if you want gas, food, or water, you're going to need cash. ATM networks are the last to get repaired. Same for internet. Cell services are not at the top of the list. You could be 4-5 days without access to your accounts. If you need anything in that time frame it's cash or the Red Cross. Children. As a foster parent we keep some cash on hand because as kids come in to our care we want to get them in school right away. How are they going to eat? You can't give them your plastic, you haven't had time to setup ""lunch accounts"" or the like. Cash always works. Along those same lines are bus tickets, clothes, supplies and what not. Not everywhere will take an ATM card, and if your money is tied up in a stock then what are you supposed to do for 3 days? Tell your new kid that he can't eat? Big Emergency problems. Like your car breaks down on the interstate. Sure it can get towed to the dealership, and yes they will add the tow to your bill, and sure you have a few days to pay it (while your car gets fixed), but how are you going to get around? Not all taxis take plastic around here.  Almost none of the busses take plastic even though they are supposed to. Lost Wallet or ID theft. Lose your wallet, good luck getting into your bank accounts. It can take weeks to establish your ID after you lose it in some cases. You want your ID, but you need your birth certificate. You have to GO to the state of birth and request it. Oh but wait, to travel you need an ID. No problem send away for it, but wait, you need to send them money to mail it. To bad all your money is tied up.  Running or Evacuating - So you need to evacuate for some reason. No big deal. But all your money is in a place you can't get to it. How do you put gas in your car. Lets stick with it and say you get to ""cash out"" an account of some kind. Guess what, they're not going to mail it to some random address. Now you're stuck fighting support centers to get them to understand that you need your funds delivered to New York even though you live in Florida.  In short, you don't need $100,000 in liquid funds, but there are a few cases that you need something liquid. You also make a lot of assumptions. For example, not every one will have health insurance, or a heath problem that is covered by their insurance. Some serious home repairs are ""down payment"" upfront. Car problems like an accident that means you need a rental can totally be up front. Especially if credit cards can't be used." The papers you would need to buy are called 'futures', and they give you the right to buy (or sell) a certain amount of oil at a certain location (some large harbor typically), for a certain price, on a certain day. You can typically sell these futures anytime (if you find someone that buys them), and depending on the direction you bought, you will make or lose money according to oil rice changes - if you have the future to get oil for 50 $, and the market price is 60, this paper is obviously worth 10 $. Note that you will have to sell the future at some day before it runs out, or you get real oil in some harbor somewhere for it, which might not be very useful to you. As most traders don't want really any oil, that might happen automatically or by default, but you need to make sure of that. Note also that worst case you could lose a lot more money than you put in - if you buy a future to deliver oil for 50 $, and the oil price runs, you will have to procure the oil for new price, meaning pay the current price for it. There is no theoretical limit, so depending on what you trade, you could lose ten times or a thousand times what you invested. [I worded that without technical lingo so it is clear for beginners - this is the concept, not the full technical explanation] The Bank Secrecy Act of 1970 requires that banks assist the U.S. Gov't in identifying and preventing money laundering. This means they're required to keep records of cash transactions of Negotiable Instruments, and report any such transactions with a daily aggregate limit of a value greater than (or equal to?) $10,000. Because of this, the business which is issuing the money order is also required to record this transaction to report it to the bank, who then holds the records in case FinCEN wants to review the transactions. EDITED: Added clarification on the $10,000 rule "Money is a token that you can trade to other people for favors. Debt is a tool that allows you to ask for favors earlier than you might otherwise. What you have currently is: If the very worst were to happen, such as: You would owe $23,000 favors, and your ""salary"" wouldn't make a difference. What is a responsible amount to put toward a car? This is a tricky question to answer. Statistically speaking the very worst isn't worth your consideration. Only the ""very bad"", or ""kinda annoying"" circumstances are worth worrying about. The things that have a >5% chance of actually happening to you. Some of the ""very bad"" things that could happen (10k+ favors): Some of the ""kinda annoying"" things that could happen (~5k favors): So now that these issues are identified, we can settle on a time frame. This is very important. Your $30,000 in favors owed are not due in the next year. If your student loans have a typical 10-year payoff, then your risk management strategy only requires that you keep $3,000 in favors (approx) because that's how many are due in the next year. Except you have more than student loans for favors owed to others. You have rent. You eat food. You need to socialize. You need to meet your various needs. Each of these things will cost a certain number of favors in the next year. Add all of them up. Pretending that this data was correct (it obviously isn't) you'd owe $27,500 in favors if you made no money. Up until this point, I've been treating the data as though there's no income. So how does your income work with all of this? Simple, until you've saved 6-12 months of your expenses (not salary) in an FDIC or NCUSIF insured savings account, you have no free income. If you don't have savings to save yourself when bad things happen, you will start having more stress (what if something breaks? how will I survive till my next paycheck? etc.). Stress reduces your life expectancy. If you have no free income, and you need to buy a car, you need to buy the cheapest car that will meet your most basic needs. Consider carpooling. Consider walking or biking or public transit. You listed your salary at ""$95k"", but that isn't really $95k. It's more like $63k after taxes have been taken out. If you only needed to save ~$35k in favors, and the previous data was accurate (it isn't, do your own math): Per month you owe $2,875 in favors (34,500 / 12) Per month you gain $5,250 in favors (63,000 / 12) You have $7,000 in initial capital--I mean--favors You net $2,375 each month (5,250 - 2,875)   To get $34,500 in favors will take you 12 months ( ⌈(34,500 - 7,000) / 2,375⌉ ) After 12 months you will have $2,375 in free income each month. You no longer need to save all of it (Although you may still need to save some of it. Be sure recalculate your expenses regularly to reevaluate if you need additional savings). What you do with your free income is up to you. You've got a safety net in saved earnings to get you through rough times, so if you want to buy a $100,000 sports car, all you have to do is account for it in your savings and expenses in all further calculations as you pay it off. To come up with a reasonable number, decide on how much you want to spend per month on a car. $500 is a nice round number that's less than $2,375. How many years do you want to save for the car? OR How many years do you want to pay off a car loan? 4 is a nice even number. $500 * 12 * 4 = $24,000 Now reduce that number 10% for taxes and fees $24,000 * 0.9 = $21,600 If you're getting a loan, deduct the cost of interest (using 5% as a ballpark here) $21,600 * 0.95 = $20,520 So according to my napkin math you can afford a car that costs ~$20k if you're willing to save/owe $500/month, but only after you've saved enough to be financially secure." "First, don't save anything in a tax sheltered vehicle. You will be paying so little tax that there will be essentially no benefit to making the contributions, and you'll pay tax when they come out. Tax free compounding for 40 years is terrific, but start that after you're earning more than a stipend. Second, most people recommend having a month's expenses readily available for emergencies. For you, that would be $1500. If you put $100 a month aside, it will take over a year to have your emergency fund. It's easy to argue that you should pick a higher pace, so as to have your emergency money in place sooner. However, the ""emergencies"" usually cited are things like home repair, car repair, needing to replace your car, and so on. Since you are renting your home and don't have a car, these emergencies aren't going to happen to you. Ask yourself, if your home was destroyed, and you had to replace all your clothes and possessions (including furniture), how much would you need? (Keep in mind any insurance you have.) The only emergency expense I can't guess about is health costs, because I live in Canada. I would be tempted to tell you to get a credit card with a $2000 limit and consider that your emergency fund, just because grad student living is so tight to the bone (been there, and 25 years ago I had $1200 a month, so it must be harder for you now.) If you do manage to save up $1500, and you've really been pinching to do that (walking instead of taking the bus, staying on campus hungry instead of popping out to buy food) let up on yourself when you hit the target. Delaying your graduation by a few months because you're not mentally sharp due to hunger or tiredness will be a far bigger economic hit than not having saved $200 a month for 2 or 3 years. The former is 3-6 months of your new salary, the latter 5-7K. You know what you're likely to earn when you graduate, right?"
