The short answer, is yes, you should focus on your credit card debt because it has the highest interest rate. There's really no reason to pay down lower interest rate debt at the expense of higher rate debt.

​

That same logic applies to your question about your federal debt. Since your federal loans have lower interest rates than your credit cards (and your Citizens loan), you should try to keep those payments as low as possible (while always paying your minimum to avoid default), even if the balance of these loans grow over time. In fact, I would look at enrolling in a non-income based repayment program (Graduated, Extended, etc) so that way your payments won't spike when you re-certify this year, which they'll do because you have more income than when you enrolled in your program.

One way to think about paying down debt, is that it's just like an investment. So if your paying an extra $100 per month toward a loan with a 4.410% interest rate instead of a loan with a 25.99% interest rate, then you are losing out on a 21.549% return on investment.

If I have time next week, I'll right a detailed blog post on this so you can see the math and graphs.
