What the Credit Card Minimum Payment Calculator is for
Estimate credit-card payoff under an entered minimum rule, a fixed payment, or a target payoff time.
The calculator keeps the balance, rate convention, payment timing, fees, and term visible so you can reproduce the result and compare it with an actual offer or statement.
The cash-flow relationship
Place every amount at the correct time
Minimum mode uses max(balance·percentage, floor)+extra; fixed mode applies one entered payment; target mode solves the level payment for the entered whole-month horizon.

Read the result in context
Use the estimate with its contract assumptions
Compare an issuer-style 2%-or-25 minimum with a fixed monthly payment, or solve the payment required for a chosen payoff month.
Issuers use different minimum-payment formulas and may include interest or fees separately. Enter the rule shown in your agreement. Fixed and target modes use the simplified nominal annual rate divided by 12; this is not a statement forecast or a universal policy.

Calculation method
Calculation method
Minimum mode uses max(balance·percentage, floor)+extra; fixed mode applies one entered payment; target mode solves the level payment for the entered whole-month horizon.
The calculator keeps full binary floating-point precision through the calculation and rounds only for display. It rejects non-amortizing payments, invalid rates, and schedules beyond the disclosed work limits.
Worked example
Practical example
Compare an issuer-style 2%-or-25 minimum with a fixed monthly payment, or solve the payment required for a chosen payoff month.
Minimum mode uses max(balance·percentage, floor)+extra; fixed mode applies one entered payment; target mode solves the level payment for the entered whole-month horizon.
Supported inputs
Precision and limits
Visible input limits
Numeric tokens accept at most 60 characters. Amounts are capped at 1e12 and annual rates at 1000%. Repayment terms are whole months up to 1200; grace, promotional, and lease periods are whole months up to 120.
Estimate, not an offer
Results model only the values entered. Lenders may use different compounding, day counts, fees, payment allocation, or rounding.
International scope
No country, tax system, government benefit, regulated disclosure, or currency is assumed. Enter one consistent currency and verify local terms separately.
Calculator-specific assumptions
Issuers use different minimum-payment formulas and may include interest or fees separately. Enter the rule shown in your agreement. Fixed and target modes use the simplified nominal annual rate divided by 12; this is not a statement forecast or a universal policy.
