How to use the debt payoff planner

Add each debt with its balance, interest rate, and minimum monthly payment, then enter any extra amount you can put toward repayment. The strategy toggle compares avalanche and snowball logic using the same monthly budget.

Avalanche usually minimises interest by attacking high-rate debt first. Snowball can feel more motivating because smaller balances disappear earlier. The best choice is the one you can follow consistently while still meeting all minimum payments.

The projections are simplified and assume rates, minimums, and extra payments stay stable. They do not include missed payments, promotional rate changes, fees, or settlement offers.
