Calculate how long it will take to pay off your debts using the snowball or avalanche method. See your payoff timeline, total interest, and savings compared to minimum payments.
This debt payoff calculator helps you create a plan to become debt-free faster. Enter all your debts, their balances, interest rates, and minimum payments. Choose between the Avalanche method (pay highest interest first to save the most money) or the Snowball method (pay smallest balance first for quick wins and motivation). Add an extra monthly payment to see how much faster you can become debt-free and how much interest you will save. All calculations happen instantly in your browser — your financial data never leaves your device.
The Avalanche method focuses on paying off debts with the highest interest rates first while making minimum payments on all others. Once the highest-rate debt is paid off, you roll that payment into the next highest-rate debt. This mathematically saves you the most money in interest over time.
The Snowball method focuses on paying off the smallest balance first while making minimum payments on all others. Once the smallest debt is eliminated, you roll that payment into the next smallest. This provides quick psychological wins that can help you stay motivated on your debt-free journey.
Use Avalanche if you want to save the most money on interest. Use Snowball if you need quick wins to stay motivated. Both work — the best method is the one you will stick with. This calculator lets you compare both strategies side by side.
Even an extra $50-100 per month can significantly shorten your payoff timeline and save thousands in interest. Use this calculator to experiment with different extra payment amounts and see the impact. Find an amount that fits your budget while making meaningful progress.
