Debt Snowball vs Avalanche: which actually pays off debt faster?

If you have more than one debt, the order you pay them off matters. Two methods dominate: snowball and avalanche. Here's the plain-English difference.

Snowball: smallest balance first

You pay the minimum on everything, then throw extra cash at your smallest debt. When it's gone, you roll that payment into the next-smallest. You build quick wins and momentum.

Avalanche: highest interest first

You pay the minimum on everything, then throw extra cash at the debt with the highest interest rate. Mathematically this saves the most money in interest.

Which is better?

Avalanche wins on pure math — less interest paid, often debt-free sooner.
Snowball wins on behavior — early wins keep you motivated, which matters more than the math if you quit.

Rule of thumb: if you're disciplined, use avalanche. If you need wins to stay on track, use snowball.

Don't forget the extra payment

Neither method works well if you only pay the minimums. Adding even $100–$200 extra per month is what actually shortens the timeline. Our free calculator shows the difference for your exact debts.
