How the Credit Card Payoff Calculator works.
Monthly interest = balance × APR ÷ 12; payoff iterates monthly paymentsEnter values in the units named in each field. The calculator retains precision during the calculation and rounds displayed currency and measurements for readability.
Worked example for the Credit Card Payoff Calculator.
For this Credit Card Payoff Calculator example, with Current balance (USD): 5000; APR (%): 20; Monthly payment (USD): 200; Calculation mode: Debt payoff mode, the calculator returns 33 months. Estimated payoff with a constant payment and APR.
What this calculation uses
Monthly interest = balance × APR ÷ 12; payoff iterates monthly payments. A card issuer may apply a different daily-balance method, fees, promotions, and payment rules.
Choose the mode that answers your question
Payoff mode starts with the balance, applies one month of interest at the entered APR, subtracts the constant payment, and repeats until the balance reaches zero. First-month interest mode stops after balance × APR ÷ 12 and does not estimate a payoff schedule. Keep APR as an annual percentage and the payment as a monthly amount in the same currency as the balance.
How monthly interest and payoff are modeled
The page converts APR to a monthly rate by dividing the percentage by 100 and then by 12. In payoff mode, each cycle calculates interest on the remaining balance, adds it to the amount due, and applies no more than the entered payment. The final payment can therefore be smaller than the regular payment. Months, total interest, total paid, and the final payment come from that month-by-month sequence.
Worked payoff example
For a $5,000 balance, 20% APR, and a constant $200 monthly payment with no new charges, this model reaches payoff in 33 months. Modeled interest totals $1,522.10, modeled payments total $6,522.10, and the final payment is $122.10 rather than a full $200. These results are planning estimates only; an issuer using daily balances, statement dates, fees, or different payment timing can produce a different schedule.
Payment and long-payoff boundaries
The payment must exceed the first month’s interest for payoff to begin. A payment at or below that amount cannot reduce the modeled balance, so the page reports a clear error instead of displaying a misleading payoff date. The simulation also stops with an error if payoff would exceed 1,200 months (100 years). A 0% APR is valid and reduces the balance only by the entered monthly payment.
Compare changes without hiding new borrowing
To compare payment plans, hold the balance and APR constant and change only the payment. A higher payment generally shortens payoff time and lowers modeled interest because less balance remains for later months. Do not use this comparison if you expect new purchases, cash advances, balance transfers, fees, or a promotional rate change; add those cash flows separately or use the issuer’s schedule.
What the estimate leaves out
The calculator does not reproduce an issuer’s daily-balance method, statement-cycle length, payment allocation, compounding date, minimum-payment formula, annual or late fees, cash-advance rate, promotional expiry, penalty APR, grace period, new transactions, refunds, credits, taxes, currency conversion, or contractual rounding. Check the current statement and card agreement before making a repayment decision.
What this calculator does not include.
A card issuer may apply a different daily-balance method, fees, promotions, and payment rules. This calculator is an arithmetic estimate, not a quote, contract, fit guarantee, tax return, benefit determination, route service, or recommendation. Current terms, product specifications, rules, and personal circumstances can change the real outcome.
Reference guidance and methodology.
Credit Card Payoff Calculator questions.
What is the difference between payoff mode and first-month interest mode?
Payoff mode repeats monthly interest and a constant payment until the modeled balance reaches zero. First-month interest mode calculates only balance × APR ÷ 12 for one month and does not produce a payoff schedule.
Why must the payment exceed first-month interest?
If the payment is equal to or below the interest added in the first modeled month, it does not reduce principal. The page reports that boundary as an error instead of showing a payoff date that cannot occur under the entered assumptions.
Why can the final payment be smaller than my regular payment?
In the last modeled month, the calculator applies only the remaining balance plus that month’s interest. It does not overpay the account to force a full regular payment.
What happens at 0% APR?
No interest is added. Payoff mode subtracts the entered payment each month until the balance reaches zero, with a smaller final payment where the balance is not an exact multiple of the payment.
Why might my card statement show different interest or payoff timing?
Issuers can use daily balances, actual statement dates, different compounding and rounding, fees, promotional or penalty rates, minimum-payment formulas, and payment-allocation rules that this constant monthly model does not reproduce.
Does FigureNest send my card balance anywhere?
No. The payoff simulation runs locally in the browser and does not use a calculation service.
