Why would anyone want to pay off their debts in a way other than “highest interest” first?
This is a slightly different reason to any other answer I have seen here about irrationality and how being rationally aware of one's irrationality (in the future or in different circumstances) can lead you to make decisions which on the face of it seem wrong. First of all, why do people sometimes maintain balances on high-interest debt when they have savings? Standard advice on many money-management sites and forums is to withdraw the savings to pay down the debt. However, I think there is a problem with this. Suppose you have $5,000 in a savings account, and a $2,000 credit card balance. You are paying more interest on the credit card than you get from the savings account, and it seems that you should withdraw some money from the savings account, and pay off the cc. However, the difference between the two scenarios, other than the interest you lose by keeping the cc balance, is your motivation for saving. If you have a credit card balance of $2,000, you might be obliged to pay a minimum payment of $100 each month. If you have any extra money, you will be rewarded if you pay more in to the credit card, by seeing the balance go down and understanding that you will soon be free from receiving this awful bill each month. To maintain your savings goal, it's enough to agree with yourself that you won't do any new spending on the cc, or withdraw any savings.  Now suppose that you decide to pay off the cc with the savings. There is now nothing 'forcing' you to save $100 each month. When you get to the end of the month, you have to motivate yourself that you will be adding spare cash to your $3,000 savings balance, rather than that you 'have to' pay down your cc. Yes, if you spend the spare cash instead of saving it, you get something in return for it. But it is possible that spending $140 on small-scale discretionary spending (things you don't need) actually gets you less for your money than paying the credit card company $40 interest and saving $100? You might even be tempted to start spending on your credit card again, knowing that you have a 0 balance, and that you 'can always pay it off out of savings'. It's easy to analogize this to a situation with two types of debt. Suppose that you have a $2,000 debt to your parents with no interest and a $2,000 loan at high interest, and you get a $2,000 windfall. Let's assume that your parents don't need the money in a hurry and aren't hassling you to pay them (otherwise you could consider the guilt or the hassle as a form of emotional interest rate). Might it not be better to pay your parents off? If you do, you are likely to keep paying off your loan out of necessity of making the regular payments. In 20 paychecks (or whatever) you might be debt free. If you pay off your loan, you lose the incentive to save. After 20 months you still owe your parents $2,000. I am not saying that this is always what makes sense. Just that it could make sense. Note that this is an opposite to the 'Debt Snowball' method. That method says that it's better to pay off small debts, because that way you have more free cash flow to pay off the larger debts. The above argues that this is a bad idea, because you might spend the increased cash flow on junk. It would be better to keep around as many things as possible which have minimum payments, because it restricts you to paying things rather than gives you the choice of whether to save or spend.
