How to Use the Debt Payoff Calculator

See how long it will take to pay off debt and how much interest you'll pay. Compare payoff timelines with and without extra payments to find motivation for accelerated debt repayment.

The Math of Debt

With each payment, a portion goes to interest (calculated on remaining balance) and the rest reduces principal. Higher interest rates mean more of each payment goes to interest rather than reducing your debt.

Extra Payment Impact

Even small extra payments can:

  • Save thousands in interest over the life of the debt
  • Cut years off your payoff timeline
  • Build momentum and motivation for financial goals

Debt Payoff Strategies

  • Avalanche: Pay highest interest rate first (mathematically optimal)
  • Snowball: Pay smallest balance first (psychologically motivating)
  • Consolidation: Combine debts at a lower rate

よくある質問

Use our calculator by entering your balance, interest rate, and monthly payment. For example, a $10,000 debt at 18% APR with $250/month payments takes 56 months to pay off, costing $3,923 in interest.
