Debt Payoff Calculator: Time to Clear One Balance
Work out how long it takes to clear a single loan or card balance with a fixed monthly payment. Enter Debt amount, Interest rate (% per year), and Monthly payment. Results show Payoff time (years), months in the breakdown, Total interest, and Total cost. One balance at a time. No avalanche/snowball ordering.
How to use
The page solves how many months are needed when each payment covers at least the monthly interest. Formula uses standard amortisation math on the remaining balance. If payment is too low, the page warns that interest is not covered. At 0% interest, months equal debt divided by payment.
Example
10,000 debt at 18% with 300 paid each month needs about 3.9 years, roughly 3,400 in interest, and 13,400 total paid. Raising the payment to 400 shortens the timeline and cuts interest materially.
Tips
Credit cards often need a payment above the monthly interest charge. This model assumes you stop adding new charges. For multiple debts, run the calculator separately per balance or use a spreadsheet for combined plans.
