What Is the Minimum Credit Card Payment Calculator?
This calculator estimates the smallest amount you must pay on your credit card this billing cycle to keep the account in good standing. Most issuers compute the minimum as a small percentage of your balance plus the interest that accrued during the month, but never less than a fixed floor amount (commonly $25–$35). This tool models that common formula. Exact rules vary by issuer and card agreement, so treat the result as an estimate.
How to Use It
Enter your current statement balance, your card's minimum payment percent (often 1%–3%), your APR, and the minimum floor amount your issuer charges. The calculator returns the estimated minimum payment along with a breakdown of the interest charge and the percent-of-balance portion.
The Formula Explained
First, monthly interest is computed as \(\text{Balance} \times (\text{APR} \div 12)\). Then the percent portion is \(\text{Balance} \times \text{percent rate}\). These are added together, and the calculator takes the larger of that sum or the fixed floor amount. If the result exceeds your full balance, the payment is capped at the balance.
$$\text{Min Payment} = \min\!\left(\text{Balance},\ \max\!\left(\text{Floor},\ P\right)\right)$$ $$P = \text{Balance}\cdot\dfrac{\text{Percent}}{100} + \text{Balance}\cdot\dfrac{\text{APR}}{1200}$$
Worked Example
Suppose you owe $2,000 at a 19.99% APR, with a 1% minimum percent and a $25 floor. Monthly interest = \(2000 \times (0.1999 \div 12) \approx \$33.32\). Percent portion = \(2000 \times 0.01 = \$20\). Sum = $53.32. Since $53.32 is greater than the $25 floor, your estimated minimum payment is $53.32.
$$2000 \times \frac{0.1999}{12} + 2000 \times 0.01 \approx 33.32 + 20 = 53.32$$
FAQ
Why is paying only the minimum costly? Most of a minimum payment goes toward interest, so the balance shrinks slowly and you pay far more over time. Paying extra each month dramatically reduces total interest.
Is the floor amount always $25? No. It depends on your card agreement; many issuers use $25–$35, or the full balance if it is smaller.
Does this match my exact bill? It approximates a common issuer formula. Your statement may use a slightly different percent, interest method, or include past-due fees.
