Debt avalanche calculator
Add each of your debts — balance, interest rate and minimum payment — and an extra amount you can pay each month. The calculator shows your debt-free date, the total interest you’ll pay and the exact payoff order each debt is cleared in.
Switch between the avalanche method (highest interest rate first, cheapest overall) and the snowball method (smallest balance first, for momentum) to see which suits you. Everything runs locally in your browser.
