How it works

Avalanche vs. snowball, in short

📉

Avalanche method

Puts every extra dollar toward your highest-interest debt first, regardless of balance. Mathematically, this minimizes the total interest you pay over the life of your debt.

❄️

Snowball method

Puts every extra dollar toward your smallest balance first, regardless of interest rate. You pay slightly more in interest overall, but early wins can make it easier to stick with the plan.

Consider a debt consolidation loan

If your average APR above is high, a fixed-rate personal loan can sometimes lower your total interest versus high-APR credit cards. Compare rates without a hard credit pull.
