I have 2 outstanding credit balances:

1. 84 K at 8.99%


And 2. 30 K at 15.99%

I got a 10000 bonus.

What's the smart move? Pay down 1, or pay down 2?

I would pay down the one with the highest interest rate first, because with a lower principal amount due you will save more interest amount than with the other loan.
