Credit Card Payoff Calculator

Estimate your debt-free date, total interest and total repayment. Add one optional extra monthly payment to compare a faster payoff plan without mixing in other debt calculators.

Your payoff dashboard

A clear payoff plan without the clutter.

Enter only your balance, APR and planned payment. An optional extra payment creates the side-by-side future comparison.

The calculation stays in this browser. Results assume a fixed APR, fixed payments, no new purchases and no fees.
How to useUse the latest statement values and a payment you can realistically repeat each month. The report is generated from the same four entries.
Enter the balanceUse the current amount owed on this credit card.
Add the APREnter the annual percentage rate shown on the statement.
Set the paymentUse the fixed amount you plan to pay every month.
Test one extra amountOptionally add a regular amount above the planned payment.
Review and reportCompare dates, interest, charts and the printable schedule.
What your result meansThe page remains focused on one credit card and one fixed-payment payoff path. Unrelated debt tools are intentionally excluded from its input and output.
Calculates the debt-free dateCreates a monthly repayment schedule until the balance reaches zero.
Measures interest and total repaymentSeparates interest from principal and totals every scheduled payment.
Compares one optional extra paymentShows the difference in payoff time and interest without adding more input fields.
Does not combine multiple cardsNo snowball, avalanche, consolidation or portfolio-level debt logic is included.
Does not estimate credit scoresCredit utilization, limits, rewards and score changes are outside this calculator.
Does not model new purchases or feesThe estimate uses a stable balance-reduction plan for clear educational comparison.
Calculation method and assumptionsThe calculator uses a disclosed month-by-month payoff simulation, together with fixed assumptions, to produce the payoff date, interest totals and repayment schedule.
Fixed APRThe annual rate is converted to a monthly rate and held constant.
Fixed paymentThe same planned amount is applied each month until the final payment.
No new chargesPurchases, cash advances, transfers, late fees and annual fees are excluded.
First payment next monthMilestone dates begin one month after the report is generated.

Monthly payoff simulation

The annual APR is converted to a monthly rate. Each month, estimated interest is calculated first, the remaining payment reduces principal, and the closing balance becomes the next month’s opening balance.

Final-payment handling

The final scheduled payment is reduced when the remaining balance plus estimated interest is lower than the regular monthly payment.

Rounding and payoff date

Currency values are rounded to cents within the monthly schedule. The estimated payoff date assumes consecutive monthly payments beginning one month after the calculation date.

Scope of the estimate

The methodology covers one credit card, one fixed monthly payment and one optional extra payment. It does not model changing minimum payments, multiple APR categories, new transactions or issuer-specific daily-balance rules.

Calculator scopeOne card and one fixed monthly payment
Calculation basisMonthly amortization simulation
FormulaThe closed-form equation is useful for an approximate month count, while the displayed result uses the iterative schedule below.
Monthly rate
r = APR ÷ (100 × 12)
Monthly interest
It = Bt−1 × r
Principal paid
PRt = Pt − It
Closing balance
Bt = max(0, Bt−1 − PRt)
Approx. months
n = −ln(1 − rB ÷ P) ÷ ln(1 + r)

Example: a $5,000 balance at 22% APR with a $250 total monthly payment is simulated month by month, including the smaller final payment.

Tips and common mistakesKeep the guidance practical and directly connected to the assumptions used by this calculator.

Useful payoff tips

  • Pay more than the statement minimum when the budget allows.
  • Keep the chosen extra amount consistent rather than relying on occasional guesses.
  • Avoid adding new purchases to the balance being calculated.
  • Review the calculation whenever the APR or planned payment changes.
  • Use windfalls to reduce principal, then recalculate the remaining schedule.

Common mistakes

  • Entering a monthly interest rate instead of the annual APR.
  • Choosing a payment that does not cover the first month’s interest.
  • Assuming the estimate includes new purchases, penalties or account fees.
  • Treating the calculated payoff date as guaranteed when payments may vary.
  • Expecting every issuer to use the same daily-balance and rounding method.
Frequently asked questionsAnswers explain what the estimate means, where it may differ from a statement and how the optional extra payment affects the result.
The payoff time depends on the balance, APR and fixed monthly payment. The calculator simulates each month until the closing balance reaches zero.
A consistent extra payment generally reduces both the number of payments and the total interest, provided no new charges are added.
The principal will not decline. This calculator asks for a planned payment above the first month’s estimated interest before creating a payoff schedule.
No. New purchases, cash advances, balance transfers, fees and penalties are excluded so the page remains a focused fixed-payment payoff calculator.
Issuers may use average daily balances, different statement dates, multiple APR categories, fees and issuer-specific rounding or payment-allocation rules.
No. Credit scoring depends on several factors, and this calculator does not estimate score changes or provide credit-repair advice.
Enter the fixed amount you realistically plan to pay. A changing statement minimum is not modelled because this calculator uses one stable monthly payment.
No. It is an educational estimate based on the entered assumptions and does not replace your card agreement or qualified guidance.

How to read this table

Each row groups the monthly schedule by calendar year. Payments made are divided between interest and principal, while the ending balance becomes the next year’s opening balance.

Choose a workable payment

  • Use an amount that can be repeated every month.
  • Keep essential expenses and emergency savings in view.
  • Do not assume occasional extra payments will always occur.
  • Recalculate whenever the regular payment changes.

Simple action plan

  • Stop adding new purchases to this balance.
  • Schedule the payment before the due date.
  • Review the balance every three months.
  • Apply windfalls to principal when practical.
  • Plan where the freed payment will go after payoff.

Method and guidance

Calculation Guide

Read the method and assumptions first, then review practical guidance, common mistakes, questions, sources, and limitations.

Calculation method and assumptions

Monthly rate

r = APR ÷ (100 × 12)

Monthly balance

Closing balance = Opening balance + Interest − Payment

The calculator simulates each month until the closing balance reaches zero.

Core assumptions

  • The APR remains fixed.
  • The selected monthly payment remains fixed until the final payment.
  • No new purchases, cash advances, transfers, or fees are added.
  • Payments are made on time once per month.
  • Currency values are rounded to cents.
  • The payoff date is an estimate.

Useful tips

  • Pay more than the minimum when practical.
  • Use a repeatable monthly amount.
  • Avoid new purchases on the calculated balance.
  • Apply windfalls to principal when suitable.
  • Review the plan after an APR change.
  • Check the latest card statement.

Common mistakes

  • Entering a monthly rate instead of APR
  • Using a payment below monthly interest
  • Assuming fees or new purchases are included
  • Treating the payoff date as guaranteed
  • Mixing multiple cards in one calculation
  • Ignoring issuer-specific interest methods
Method note: The report uses the same month-by-month calculation as the detailed schedule. Recalculate whenever the balance, APR, or planned payment changes.
