I got into a discussion with a colleague at work about what I should do with my bonus. I told him about all the debt I have, and he told me, “You know what they say. You should pay off the lowest debt first.” This made me think a little as my mom had mentioned the same thing to me when I told her about my student loan debt. With all this money coming in, I will be paying off a lot of my debt and I will need to choose what loan to pay off.  Do I pay off the lower amount or the higher interest loan?

I have always believed that paying off the highest interest rate first is the best approach. This way you “lose” less money. I don’t see a problem with making your regular monthly payments and using any extra money to pay off the highest interest rate loan. I just don’t see why you would think paying off the lowest debt first would be the right move. Maybe when you get down to a few hundred dollars, but why not spend that money on the high interest loan so you pay less in interest the next time around. The only advantage I see to paying off the lower debt is the sense of satisfaction that you have one less debt to pay off.

You may have one less debt, but in the long run you are spending more money. $1000 less at 10% interest is $100. $1000 less at 5% is only $50. You put the $1000 into the 5% interest loan, you will spend an extra $100 on the 10% loan. You lose $50 by paying off the lower debt. I would rather keep this $50 and reinvest into the loan. Paying off the higher debt is always a win - win situation. That is why I am using my extra money to pay off my high interest student loans.
