Frequently Asked Questions
?What is the debt snowball method?
The snowball method pays off debts from smallest balance to largest, regardless of interest rate. Each time a debt is eliminated, its payment is rolled into the next smallest debt, creating a 'snowball' effect.
?What is the debt avalanche method?
The avalanche method targets the debt with the highest interest rate first, then moves to the next highest. This minimizes the total interest paid over time.
?Which strategy is better: snowball or avalanche?
Avalanche saves more on interest, but snowball provides quicker psychological wins. The best strategy depends on whether you need motivation (snowball) or want to minimize cost (avalanche).
?How does the extra payment work?
The extra payment is added on top of all minimum payments and applied entirely to the target debt (smallest balance or highest rate, depending on strategy). When that debt is paid off, the freed-up payment rolls to the next.
?Is my financial data private?
Yes, all calculations run entirely in your browser. Your debt balances, interest rates, and payment details are never sent to any server.
?Is this tool free to use?
Yes, this tool is 100% free with no sign-up required. Use it as many times as you need.
?Can I add more than three debts?
Absolutely. Click the 'Add Debt' button to add as many debts as you have. The calculator handles any number of debts.
?What if my payment doesn't cover the interest?
If your total payments (minimums plus extra) don't cover the accruing interest on a debt, the balance will grow and the calculator may not find a payoff date within 100 years.
?Does the calculator account for compound interest?
Yes, the tool calculates monthly compound interest on each debt, providing accurate payoff timelines and total interest figures.
?Can I share my results?
Strategy and extra payment values are stored in the URL. You can copy and share the URL to revisit or share your calculation.
