<prompt> Human: Quick question for you guys. I went through the FAQ and decided on using the first method to pay off debt. I have 3 cards, going from 400, 700, and 1500. The 400 has a whooping interest rate of 26.99. While the 1500 has the lowest. Which would I benefit more from paying off first?  <response>: If youre using the avalanche method which is a good idea, you should pay off the account with the highest interest rate first, even if it has the smaller balance.For every 100 you owe at a 26.99 interest rate, you will have to pay 26.99 per year in interest.For every 100 you owe at 10 interest rate, you will have to pay 10.00 per year in interest.As a result, if you have 100 to pay off your debts with, you should pay off the one that would cost you 26.99 rather than the one that would cost you 10.
