Enter a value for extra monthly payment (beyond all minimums) to see your result.
Compares the snowball method (pay lowest balance first) and the avalanche method (pay highest APR first) for paying off multiple debts. Shows total interest, months to payoff, and debt-free date for both strategies so you can choose the best plan.
Avalanche targets the 22.99% debt first, saving more in interest. Snowball also targets debt 1 first because it has the lower balance — both strategies happen to agree when the smaller debt also has the higher rate.

In the snowball method, you pay the minimum on all debts and direct any extra money at the debt with the lowest balance first. Once that debt is gone, you roll its payment into the next smallest balance. The 'snowball' grows as each debt is eliminated, accelerating payoff. It's motivating because you eliminate debts faster.
The avalanche method targets the highest-APR debt first. You pay minimums on everything else and throw all extra money at the most expensive debt. This is the mathematically optimal strategy — it minimizes total interest paid over the payoff period.
Avalanche wins mathematically (less total interest). Snowball wins psychologically for some people because quick wins from paying off small balances build momentum. If your highest-rate debt also has the smallest balance, both strategies are identical. Choose the method you're most likely to stick with.
When APRs are equal, avalanche and snowball pay the same total interest. The only difference is the order debts are targeted — snowball starts with the lowest balance while avalanche starts with the highest rate (which in this case could be any debt). The total payoff time and interest will be the same.
Yes — significantly. Even an extra $50/month on a typical debt load can cut months off your payoff timeline and save hundreds or thousands in interest. The debt-elimination effect accelerates because freed minimums from paid-off debts compound over time.
Most financial planners recommend a small emergency fund ($1,000–$2,000) before attacking high-interest debt aggressively, so an unexpected expense doesn't force you back into debt. Once you have a basic buffer, throwing extra money at high-APR debt usually beats keeping it in savings.
