How to Use the Debt Payoff Calculator

  1. Add your debts - enter each debt with its current balance, APR (interest rate), and minimum monthly payment.
  2. Set extra payment - how much extra you can put toward debt each month above minimums.
  3. Choose a strategy - Avalanche (highest APR first) saves the most money. Snowball (lowest balance first) provides psychological wins and motivation.
  4. Compare the strategy results against minimum-only payments to see total interest savings.

Frequently Asked Questions

The avalanche method makes minimum payments on all debts and throws every extra dollar at the highest interest rate debt first. When that debt is paid off, you "avalanche" that payment to the next highest rate. This is mathematically optimal and minimizes total interest paid. On two debts of $4,000 at 22% and $6,000 at 12%, avalanche typically saves $400-800 in interest compared to snowball depending on payment amounts.
