How to Use the Debt Payoff Calculator

  1. Add your debts — Select the debt type (credit card, mortgage, car loan, etc.), then enter your current balance, interest rate, and minimum monthly payment. Add as many debts as you have.
  2. Enter an extra monthly payment — Even $50–$100 extra per month makes a dramatic difference. The calculator shows you exactly how much time and interest you save.
  3. Hit Calculate Payoff — Your Debt Summary, Extra vs Minimums comparison, and full Avalanche vs Snowball results appear instantly.
  4. Check the Extra Payment vs Minimums box — See side by side what paying minimums only costs you vs adding your extra payment — in real dollars and months.
  5. Compare Avalanche vs Snowball — Both methods are calculated simultaneously. See which one wins for your specific debts, with a full breakdown of interest saved, total cost, and months saved.
  6. Export to Excel — Download your full month-by-month breakdown for both methods to track progress and stay accountable.
  7. Copy Link — Share your exact scenario with a spouse, friend, or financial advisor. The link saves all your inputs automatically.

Pro tip: After you calculate, bump your extra payment by $100 and hit Calculate again. The difference will surprise you — that’s the debt rollover effect kicking in.

Avalanche vs Snowball — What’s the Difference?

Avalanche targets your highest interest rate first. Saves the most money overall.
