Snowball vs avalanche: how the methods work
Both methods have you pay the minimum on every debt and put any extra toward one target debt. The snowball targets your smallest balance first for quick wins and momentum. The avalanche targets your highest interest rate first, which mathematically saves the most interest. This calculator amortizes each debt month by month to show the payoff date and total interest for each approach.
Which method should you choose?
- Avalanche (highest rate first) saves the most money in interest.
- Snowball (smallest balance first) delivers faster early wins, which helps many people stay motivated.
- The gap between the two is often smaller than people expect; the best method is the one you will actually stick with.
- Adding even a small extra monthly payment usually shortens the timeline meaningfully.
A quick example
With a small high-interest card, a medium store card, and a larger low-rate loan, avalanche pays the high-interest card first to cut interest, while snowball clears the small card first for an early win. The calculator shows both timelines side by side so you can see the trade-off for your own numbers.
Common questions
Avalanche saves the most interest by targeting your highest rate first. Snowball clears your smallest balance first for faster motivation. The best method is the one you can stay consistent with.
It depends on your balances, interest rates, and how much you pay each month above the minimums. This calculator estimates your debt-free date for both methods based on the numbers you enter.
Yes. Extra payments go straight to principal, which reduces the interest that accrues going forward and can shorten your timeline significantly.
If the payments are not realistic, a payoff plan alone may not be enough. Consolidation can lower your rate, and if you truly cannot pay, debt relief is a different path. We can help you figure out which fits.
