Why fixed payments and minimum payments need different payoff models
An issuer’s minimum can change as the balance changes. A fixed-payment projection keeps the same monthly amount, so extending the first month’s minimum indefinitely describes a different strategy.

A minimum-payment formula may combine a balance percentage, a fixed floor and specified charges. The calculator instead asks you to choose a fixed monthly payment. It does not recalculate an issuer’s minimum every month or determine whether your chosen amount satisfies the current statement. The contractual payment requirement remains a separate constraint.
Compare two interest-free months
For illustration only, suppose a minimum-payment rule requires 5% of the outstanding balance, starting from 2,000 with no interest. The first minimum is 100, leaving 1,900. The next minimum under that invented rule is 95. A fixed payment of 100 would repay 5 more in the second month. The example is not a claim about the formula used by any issuer; it isolates the difference between a changing percentage and a fixed amount.
Keep the statement requirement in the plan
A fixed payment can serve as a repayment budget, but actual payments must still satisfy the applicable contract. Recalculate after rate changes or new purchases. The model’s final payment may be smaller than the chosen amount so that it does not exceed the remaining balance. It does not configure automatic payments, check due dates or replace reviewing each statement for changes and additional charges.
