What this tool does
The Debt Free Date Calculator helps you figure out exactly when you will pay off all your debts — credit cards, car loans, student loans, personal loans, and more. Enter each debt with its current balance, interest rate, and minimum payment, then choose how much extra you can put toward debt each month. The tool runs a full month-by-month simulation and tells you your exact debt-free date.
Beyond just giving you a date, the calculator shows you the total interest you will pay, how much interest you save by adding extra payments, and a timeline showing which debt gets paid off first. A line chart illustrates how your total balance shrinks over the months and years ahead.
You can share your results with a unique URL that encodes all your debt information — useful for planning sessions with a partner or financial advisor.
Avalanche vs Snowball method
These are the two most popular debt payoff strategies, and this calculator supports both:
**Avalanche Method** After paying minimums on all debts, every extra dollar goes to the debt with the highest interest rate. Once that debt is paid off, you roll its payment into the next-highest-rate debt. The avalanche method minimizes the total interest you pay over time, making it the mathematically optimal strategy. It is ideal if you are motivated by numbers and want to minimize cost.
**Snowball Method** After paying minimums on all debts, every extra dollar goes to the debt with the smallest remaining balance. Once that debt is paid off, you roll its full payment into the next-smallest debt. The snowball method generates early wins — you pay off debts faster in terms of account count — which many people find highly motivating. Research shows this psychological boost helps people stay on track even if they pay slightly more interest overall.
Which should you choose? If staying motivated is your challenge, the snowball method often works better in practice. If you are disciplined and want to minimize cost, the avalanche method saves more money.

FAQs
**Q: How accurate is the debt-free date?** A: The calculator uses standard amortization math and simulates every month individually. Results are very accurate for fixed-rate debts with constant payments. Variable-rate debts or accounts with fees may see some variance.
**Q: What if I can't afford any extra payment?** A: Set the extra monthly payment to 0. The calculator will show your payoff timeline using minimum payments only. This is useful as a baseline to understand the cost of paying minimums.
**Q: Why does the snowball method sometimes show a later date than avalanche?** A: Because the snowball method targets the smallest balance first rather than the highest-rate debt, you may pay slightly more in total interest, which can push your debt-free date back by a few months. The tradeoff is psychological momentum from eliminating individual debts sooner.
**Q: Is my financial data stored anywhere?** A: No. All calculations run entirely in your browser. Nothing is sent to any server. The optional share link encodes your data as a URL parameter using base64, so the data lives only in the link itself.
