Debt snowball vs avalanche calculator

Two proven ways to pay off debt faster: the snowball (clear the smallest balance first for quick wins) and the avalanche (attack the highest interest rate first to save the most money). Enter your debts below to see which gets you debt-free sooner — and what each costs in interest. Everything runs in your browser; we never see or store your numbers.

Which method should you choose?

Mathematically, the avalanche method almost always wins — by paying off your highest-APR debt first, you cut the interest that compounds fastest, so you usually pay less overall and finish at least as quickly. The snowball method ignores rates and targets your smallest balance first. It can cost a little more interest, but knocking out a whole debt early gives a motivation boost that helps many people actually stick with the plan.

The honest answer: the best method is the one you'll follow. If you're disciplined and want to minimize cost, choose avalanche. If you've struggled to stay motivated, the early win from snowball may be worth a small premium. Either way, the calculator shows that the extra monthly payment — not the ordering — does most of the heavy lifting.

When extra payments aren't enough

If the tool shows your balances barely moving, the minimums may be nearly equal to the interest accruing each month — a sign the debt is too large to outrun on your own. That's the point where a consolidation loan (one lower fixed rate), a nonprofit debt management plan, or debt settlement may be worth comparing. None is free of trade-offs, and we explain each one plainly before you decide.
