This free debt payoff calculator compares the snowball and avalanche strategies to show how fast you can become debt-free. Add each of your debts with its balance, APR, and minimum payment, then set an extra monthly amount. The avalanche method attacks the highest APR first to save the most interest, while the snowball method clears the smallest balance first for quick wins. Freed-up minimums roll into the next target automatically. Runs entirely in your browser.
