Credit Card Minimum Payment Calculator

The credit card minimum payment calculator estimates the least amount due under a common issuer-style rule: compare a percentage of the statement balance with a fixed dollar floor, use the larger amount, cap that base amount at the balance, and then add any past-due amount. It is designed for the monthly cash flow question: what is the minimum payment due this statement cycle?

That is a different question from debt payoff. The credit card payoff calculator estimates how long a fixed payment takes to eliminate a balance. The credit card calculator can include ongoing monthly charges while estimating payoff. The credit card interest calculator estimates one cycle’s finance charge from a daily periodic rate. This page is about the minimum due formula itself.

Inputs and what they mean

Enter the statement balance shown for the card or the balance you want to model. Enter the minimum percentage from the card’s terms, such as 2% or 3%. Enter the minimum dollar amount, sometimes called the floor, such as $25 or $35. Finally, enter a past-due amount only if your statement requires it in addition to the current minimum.

Do not treat the result as the payment you should make. It is the least required payment under the entered rule. Paying only the minimum may avoid late-payment consequences when it posts on time, but it usually leaves a revolving balance that continues to accrue interest. If you can pay more, use a payoff calculator to see how much time and interest the extra dollars save.

Formula

The calculator first computes the percentage amount:

$\text{percentage amount} = \text{balance} \times \frac{\text{minimum percentage}}{100}$

Then it compares that amount with the dollar floor and caps the result at the balance:

$\text{base minimum} = \min(\text{balance}, \max(\text{percentage amount}, \text{dollar floor}))$

Past-due amounts are added after the base minimum:

$\text{minimum due before cap} = \text{base minimum} + \text{past-due amount}$

The final total is capped at the balance plus past-due amount:

$\text{estimated minimum due} = \min(\text{balance} + \text{past-due amount}, \text{base minimum} + \text{past-due amount})$

The remaining amount after paying the minimum is:

$\text{remaining after payment} = \max(0, \text{balance} + \text{past-due amount} - \text{estimated minimum due})$

Example: estimating a minimum payment

Use the default values: $1,500 statement balance, 3% minimum percentage, $25 dollar floor, and $0 past due.

$\text{percentage amount} = \$1{,}500 \times \frac{3}{100} = \$45$

The percentage amount, $45, is larger than the $25 floor, so the base minimum is $45. Because there is no past-due amount, the estimated minimum payment is also $45. The remaining balance after making only that payment is:

$\$1{,}500 - \$45 = \$1{,}455$

The compute output for those defaults is:

If the balance were $10 with the same $25 floor, the base minimum would be capped at $10 rather than showing $25. If the default example also had $30 past due, the estimated minimum due would become $75, and the remaining amount modeled would be $1,455 because the past-due amount was included in the payment.

How minimum payments are set

Issuers use minimum payment formulas to define the least acceptable monthly payment. A common structure is the greater of a percentage of balance or a fixed floor. Some card agreements add interest and fees to that amount, use different percentages, treat promotional balances separately, or require any amount over the credit limit. This calculator models the percentage-plus-floor structure shown in the inputs, so it is transparent but not universal.

The minimum can fall as the balance falls, which is convenient for cash flow but slow for debt reduction. When the required amount shrinks, less money attacks the remaining principal. A fixed payment above the minimum can shorten the payoff period because it does not automatically shrink with the balance.

Interest, utilization, and credit-score context

Paying the minimum by the due date can help avoid a late fee, but it usually does not avoid interest on a carried balance. The unpaid portion can continue accruing interest under the card’s APR. To estimate the current cycle’s interest, use the credit card interest calculator. To estimate how many months a larger fixed payment would take, use the credit card payoff calculator.

Minimum payments also affect credit utilization indirectly. A small minimum may leave a large reported balance compared with the card limit. If the account reports before a larger payment posts, utilization may remain elevated. Use the credit utilization calculator to estimate the reported balance divided by the credit limit and the payment needed to reach a target percentage.

Practical tips

• Pay at least the minimum by the due date to keep the account current.
• Pay more than the minimum when possible to reduce interest and payoff time.
• Check whether your issuer adds interest, fees, or over-limit amounts to the minimum formula.
• Do not confuse the minimum due with the statement balance needed to restore a grace period.
• Recalculate when the balance changes significantly or a past-due amount appears.

Informational note

This calculator is educational and does not determine your legal payment obligation. Your card statement, card agreement, issuer policies, and applicable law control the actual minimum due, fees, late-payment consequences, and interest charges.
