About this calculator
Two common debt payoff strategies are the avalanche method and the snowball method. The avalanche method directs extra payments to the highest-interest debt first, which minimises total interest paid over time. The snowball method targets the smallest balance first, eliminating individual debts sooner and providing psychological motivation to stay on track.
Even a small additional monthly payment beyond the minimum can cut years off a debt payoff timeline and save hundreds or thousands in interest. Because interest compounds on the outstanding balance, reducing principal faster has an accelerating effect — each extra payment reduces future interest charges as well.
