Debt Snowball vs Avalanche Calculator

Snowball vs Avalanche: Which Is Right for You?

Both strategies use the same total monthly payment — the only difference is which debt gets the extra money first.

Debt Snowball

Pay minimum on all debts. Put every extra dollar toward the smallest balance first. Once that debt is gone, roll its minimum payment into the next smallest. The name comes from how momentum builds — like a snowball picking up speed as it rolls.

Best for: People who need visible wins to stay motivated. Seeing a debt disappear completely (even a small one) releases a psychological reward that keeps the plan moving.

Debt Avalanche

Pay minimum on all debts. Put every extra dollar toward the highest APR first. Once that debt is eliminated, redirect its minimum to the next highest-rate debt.

Best for: Minimizing total interest paid. Mathematically, attacking the highest-rate debt first stops the most expensive interest from compounding. Over time — especially with large high-rate balances — the avalanche typically costs less.

Which Saves More Money?

If your debts have similar interest rates, the difference between strategies is small. If one debt has a significantly higher APR (for example, a 25% credit card alongside a 6% car loan), the avalanche wins by a larger margin. This calculator shows the exact difference for your specific debts.

The Most Important Step

Both strategies require consistency. Choosing either approach and sticking with it will always outperform paying random amounts to random debts. Pick the method you'll actually follow through with — then commit to it month after month.
