    How to Use the Debt Payoff Calculator

    Enter the balance, interest rate, and minimum payment for each of your debts (up to 4), plus any extra amount you can pay each month. Choose a strategy and the calculator simulates your full payoff timeline.

    Snowball Method

    Pay off your smallest balance first, regardless of interest rate, while making minimum payments on everything else. Once a debt is paid off, that payment amount rolls into the next smallest debt. This method prioritizes quick wins and motivation.

    Avalanche Method

    Pay off your highest-interest-rate debt first while making minimum payments on everything else. This method minimizes the total interest you pay over time, though it may take longer to see your first debt disappear.

    Which Should You Choose?

    Avalanche saves more money mathematically. Snowball often works better psychologically, since early wins build momentum to keep going. Try both strategies in the calculator and see the actual difference for your specific debts.
