What It Does

Use the calculator with intent

The Debt Payoff Strategy Planner is a robust tool designed to compare popular debt repayment methods: the debt avalanche and debt snowball. By inputting your current debts, it calculates the total interest paid and the time to become debt-free under each strategy, empowering you to make an informed decision.

This calculator is ideal for anyone with multiple debts—whether credit cards, personal loans, student loans, or medical bills—who wants to accelerate their repayment journey. It's especially useful for individuals feeling overwhelmed by debt and seeking a clear, data-driven plan to achieve financial freedom faster and more efficiently.

Interpreting Results

Start with Payoff Months. Then compare Total Interest and Debt Free Date before deciding what changes the answer most.

Input Steps

Field by field

  1. 1

    Debts

    List each debt's balance, APR, and minimum payment exactly, then enter the extra monthly amount you can direct. Avalanche means highest APR first, snowball means smallest balance first, and hybrid is only useful if you need both momentum and math.

  2. 2

    Extra Monthly Payment

    Read debt-free date, total interest, and payoff order together. Avalanche should minimize total interest, while snowball usually produces the fastest early account closures.

  3. 3

    Strategy

    If avalanche only saves a little but snowball closes a balance much sooner, behavior can matter more than perfect optimization. When APRs are 20%+, interest minimization usually becomes the stronger argument.

  4. 4

    Payoff Priority Order

    Pick one strategy and follow it for at least a quarter instead of switching monthly. Pair the plan with the credit card payoff calculator or debt-to-income calculator if you need to free up credit or qualify for financing.

  5. 5

    Start Year

    Re-run whenever a debt is paid off, rates change, or extra-payment capacity changes by 10% or more. Track total principal remaining, next payoff date, and interest saved versus your starting plan.

  6. 6

    Start Month

    Enter start month with realistic baseline assumptions before moving to sensitivity checks.

    Run one base case and one sensitivity case before trusting a single output.

The short answers readers usually want after the first pass.

The Debt Avalanche strategy prioritizes paying off debts with the highest interest rates first, saving you the most money on interest over time. The Debt Snowball strategy, conversely, focuses on paying off the smallest debt balances first, regardless of interest rate. This provides psychological wins and momentum by quickly eliminating debts, which can be highly motivating for some individuals to stick to their plan.
