The Avalanche Strategy

Target the debt with the highest interest rate (APR) first while paying minimums on the rest. Mathematically minimizes the total interest you pay over the life of your debt.

The Snowball Strategy

Target the debt with the lowest balance first. Gives fast psychological wins by eliminating accounts early, building momentum to stay committed.
