How this calculator works
Each month adds interest at the annual percentage ÷ 100 ÷ 12, then subtracts the fixed payment. The final payment is reduced to the remaining balance plus interest. No new borrowing, fees, daily accrual or changing rates are included. Payments that do not cover interest cannot repay the balance. Estimates beyond 1,200 months are flagged rather than presented as a completed payoff; a residual of one cent or less ends the simulation. Credit cards often accrue interest daily and use changing minimum payments; compare your issuer’s statement.
Dollar results are in USD and generally rounded to the nearest whole dollar; salary equivalents and percentage outputs use two decimal places. Calculations retain JavaScript floating-point precision between steps rather than rounding every payment to cents. Displayed components may not sum exactly to displayed totals. Payoff times use whole monthly payment periods. Defaults are examples, not current rates or recommendations.

Worked example: $8,000 balance at 24% APR
With an $8,000 balance, 24% APR and a fixed $300 monthly payment, the default model pays the balance off in about 39 months. Estimated total payments are about $11,547, including roughly $3,547 in interest.
Credit cards often accrue interest daily and minimum payments can change, so your issuer statement is the authoritative source for actual payoff amounts.
Practical guide
How to use the payoff estimate
- Increase the monthly payment in small steps to see how much time and interest each increase can save.
- If your payment is close to or below monthly interest, payoff can become extremely slow or impossible under a fixed-payment model.
- Avoid adding new charges if you are using a payoff plan.
- For several debts, compare this page with the Debt Payoff Calculator one balance at a time.
How to use the result
Change one assumption at a time to compare scenarios. For example, test a lower rate, larger contribution, different term or extra payment. This makes the calculator most useful as a decision-support tool rather than a single-number answer.
Important financial decisions can depend on taxes, fees, eligibility rules, lender policies, market returns and personal circumstances that this simplified calculator does not capture.
