How this estimate works
- Both strategies pay minimums on all debts first.
- Avalanche applies extra payment to the highest APR debt until it is paid off.
- Snowball applies extra payment to the smallest balance until it is paid off.
- The calculator simulates monthly interest and payoff progress for each method.

Common questions
Which method is mathematically better?
Avalanche is usually better mathematically because it attacks higher-interest balances first.
Why would anyone choose snowball?
Snowball can create faster visible wins, which may help some people stay consistent.
Should I still make minimum payments?
Yes. Both methods assume you continue making minimum payments on every debt and add extra money to one target debt.
