Debt Snowball vs. Avalanche Calculator
Enter your debts once and see both payoff strategies side by side — which one gets you to zero faster, and which one costs less in total interest.
What Is the Debt Snowball Method?
The debt snowball method sorts your debts smallest balance to largest, then throws every extra dollar at the smallest one while paying just the minimum everywhere else. Once that balance hits zero, its payment rolls into the next-smallest — the velocity payoff effect that speeds up every payoff after the first, and a fast, visible win early on that's designed to keep you motivated through the rest of the list.
What Is the Debt Avalanche Method?
The debt avalanche method sorts the same list by interest rate instead, highest to lowest, and attacks the most expensive debt first. Mathematically, this is the cheapest possible order — no other sequence pays less total interest for the same monthly payment — though the first full payoff can take longer to arrive if your highest-rate debt isn't your smallest one.
Which Is Better: Snowball or Avalanche?
Avalanche wins on the math every time — it either saves money or, at worst, ties snowball if the order happens to be identical. But the method that actually gets followed to zero is the one that works, and for a lot of people, the quick psychological win of erasing a whole balance early is what keeps the plan alive. Run both numbers above and decide which trade-off — speed of motivation versus total cost — matters more for you.

Frequently Asked Questions
What is the debt snowball method?
The debt snowball method targets your smallest balance first, paying its minimum on every other debt while throwing all extra money at that one. Once it's paid off, its payment rolls into the next-smallest balance, and so on. It's built around quick wins to keep you motivated, even if it isn't always the cheapest path mathematically.
What is the debt avalanche method?
The debt avalanche method targets your highest interest rate first instead of your smallest balance, again paying minimums everywhere else and rolling payments forward once a debt clears. It minimizes total interest paid over the life of the payoff, though the first debt to disappear may take longer than it would under the snowball method.
Which is better: snowball or avalanche?
Avalanche always saves the same or more in total interest, since it always attacks the most expensive debt first. Snowball can be worth the extra cost if the psychological win of erasing a full balance quickly is what keeps you actually sticking to the plan — the "best" method is whichever one you'll follow through to zero.
Do I still pay minimums on every debt with these methods?
Yes. Both methods only change where your extra money goes — every other debt still gets at least its minimum payment every month so nothing goes delinquent while you focus your extra payment on one target debt at a time.
What happens to a debt's minimum payment once it's paid off?
It gets added to your extra payment pool and rolled into the next target debt — this is the "snowball" effect the method is named for. Your total monthly payment amount stays the same throughout; it just concentrates on fewer and fewer debts as each one clears.
