How This Calculator Works

This calculator compares two popular debt repayment strategies: **Avalanche Method**: Pay extra toward highest interest debt first • Mathematically optimal • Saves the most money on interest • May take longer to see debts disappear **Snowball Method**: Pay extra toward smallest balance first • Provides quick wins for motivation • Costs slightly more in interest • Debts disappear faster (psychologically rewarding) Both methods: Pay minimums on all debts, then direct extra payments strategically.
