How to use the Credit Card Payoff Calculator

How it works
Each month interest of balance x APR / 12 is added and your payment is subtracted. The number of months is -ln(1 - balance x i / payment) / ln(1 + i), where i is the monthly rate. If your payment is not larger than the monthly interest, the balance never falls.
Worked example
- Input: Card balance: 5000; APR (%): 18; Monthly payment: 200
- Result: Months to pay off: 32; Years: 2.6; Total interest: 1,313.60; Total paid: 6,313.60
Common uses

- Compare paying 200 a month with paying 300

Tips for the best result
- Use the rate exactly as your bank or lender quotes it, and check whether it is a yearly or a monthly rate.
- Run two or three scenarios, such as a higher and a lower rate, to see the range of outcomes.
- Add fees, insurance and taxes separately, because many calculators leave them out.
- Round only at the end so small differences do not add up.
Common mistakes to avoid
- Typing a monthly rate where a yearly rate is expected, which makes the answer far too small.
- Mixing years and months in the term field.
- Treating the result as a promise. Real rates, fees and taxes change over time.
- Forgetting that taxes and charges differ from country to country.
