What is the preferred way to set up personal finances?
You don't state where you are, so any answers to this will by necessity be very general in nature. How many bank accounts should I have and what kinds You should have one transaction account and one savings account. You can get by with just a single transaction account, but I really don't recommend that. These are referred to with different names in different jurisdictions, but the basic idea is that you have one account where money is going in and out (the transaction account), and one where money goes in and stays (the savings account). You can then later on, as you discover various needs, build on top of that basic foundation. For example, I have separate accounts for each source of money that comes into my personal finances, which makes things much easier when I sit down to fill out the tax forms up to almost a year and a half later, but also adds a bit of complexity. For me, that simplicity at tax time is worth the additional complexity; for someone just starting out, it might not be. (And of course, it is completely unnecessary if you have only one source of taxable income and no other specific reason to separate income streams.) how much (percentage-wise) of my income should I put into each one? With a single transaction account, your entire income will be going into that account. Having a single account to pay money into will also make life easier for your employer. You will then have to work out a budget that says how much you plan to spend on food, shelter, savings, and so on. how do I portion them out into budgets and savings? If you have no idea where to start, but have an appropriate financial history (as opposed to just now moving into a household of your own), bring out some old account statements and categorize each line item in a way that makes sense to you. Don't be too specific; four or five categories will probably be plenty. These are categories like "living expenses" (rent, electricity, utilities, ...), "food and eating out" (everything you put in your mouth), "savings" (don't forget to subtract what you take out of savings), and so on. This will be your initial budget. If you have no financial history, you are probably quite young and just moving out from living with your parents. Ask them how much might be reasonable in your area to spend on basic food, a place to live, and so on. Use those numbers as a starting point for a budget of your own, but don't take them as absolute truths. Always have a "miscellaneous expenses" or "other" line in your budget. There will always be expenses that you didn't plan for, and/or which don't neatly fall into any other category. Allocate a reasonable sum of money to this category. This should be where you take money from during a normal month when you overshoot in some budget category; your savings should be a last resort, not something you tap into on a regular basis. (If you find yourself needing to tap into your savings on a regular basis, adjust your budget accordingly.) Figure out based on your projected expenses and income how much you can reasonably set aside and not touch. It's impossible for us to say exactly how much this will be. Some people have trouble setting aside 5% of their income on a regular basis without touching it; others easily manage to save over 50% of their income. Don't worry if this turns out a small amount at first. Get in touch with your bank and set up an automatic transfer from your transaction account to the savings account, set to recur each and every time you get paid (you may want to allow a day or two of margin to ensure that the money has arrived in your account before it gets taken out), of the amount you determined that you can save on a regular basis. Then, try to forget that this money ever makes it into your finances. This is often referred to as the "pay yourself first" principle. You won't hit your budget exactly every month. Nobody does. In fact, it's more likely that no month will have you hit the budget exactly. Try to stay under your budgeted expenses, and when you get your next pay, unless you have a large bill coming up soon, transfer whatever remains into your savings account. Spend some time at the end of each month looking back at how well you managed to match your budget, and make any necessary adjustments. If you do this regularly, it won't take very long, and it will greatly increase the value of the budget you have made. Should I use credit cards for spending to reap benefits? Only if you would have made those purchases anyway, and have the money on hand to pay the bill in full when it comes due. Using credit cards to pay for things is a great convenience in many cases. Using credit cards to pay for things that you couldn't pay for using cash instead, is a recipe for financial disaster. People have also mentioned investment accounts, brokerage accounts, etc. This is good to have in mind, but in my opinion, the exact "savings vehicle" (type of place where you put the money) is a lot less important than getting into the habit of saving regularly and not touching that money. That is why I recommend just a savings account: if you miscalculate, forgot a large bill coming up, or for any other (good!) reason need access to the money, it won't be at a time when the investment has dropped 15% in value and you face a large penalty for withdrawing from your retirement savings. Once you have a good understanding of how much you are able to save reliably, you can divert a portion of that into other savings vehicles, including retirement savings. In fact, at that point, you probably should. Also, I suggest making a list of every single bill you pay regularly, its amount, when you paid it last time, and when you expect the next one to be due. Some bills are easy to predict ("$234 rent is due the 1st of every month"), and some are more difficult ("the electricity bill is due on the 15th of the month after I use the electricity, but the amount due varies greatly from month to month"). This isn't to know exactly how much you will have to pay, but to ensure that you aren't surprised by a bill that you didn't expect.
