Avalanche saves $532 in interest by paying off your 1st debt (the higher-APR one) first.

Simulates real monthly amortization for both debts: interest accrues monthly, minimum payments are made on every open balance, and once a debt is paid off its minimum payment rolls onto the remaining debt along with your extra payment. Minimum payments are estimated as 2% of balance or this month's interest plus $25, whichever is larger, since actual minimums vary by lender. Excludes changing APRs, new charges, fees, and credit-score effects. Not financial advice — a debt consolidation loan may cost less than either scenario if you qualify for a lower blended rate.

Frequently Asked Questions

Everything you need to know.

Which method saves more money — avalanche or snowball?

The avalanche method always saves more interest because you eliminate highest-rate debt first. In a real payoff plan, where a finished debt's payment rolls onto the next one, the typical difference is $500–$2,000. This calculator's simplified two-debt estimate pays each balance off independently without that rollover, so its gap will usually run higher than a real plan's — treat it as a rough upper bound on the two methods' difference, not a payoff schedule. Either way, the snowball method has a documented psychological advantage that helps people actually stay with the plan.

Can I combine both methods?

Yes — a hybrid approach pays off any debt under $1,000 first (quick win), then switches to avalanche ordering. This gives you early momentum while minimizing total interest.
