See how your minimum payment splits between interest and principal.
💳 Minimum payments barely cover interest — paying only the minimum means decades to pay off. Pay more whenever possible.
The minimum paymentis the smallest amount your card issuer will accept each month without charging a late fee or reporting you as delinquent. It is calculated as a small percentage of your balance (usually 1%–3%) plus any interest and fees accrued that month. This calculator shows exactly where your minimum payment goes — how much is interest, how much actually reduces your debt, and how long you'd be paying if you only ever sent the minimum.
The math is brutal. On a typical balance, the minimum payment is deliberately set low enough that most of it covers interest, leaving only a tiny sliver for principal. This is by design: a low minimum keeps you paying for as long as possible. Understanding the breakdown is the first step to escaping it.
Every issuer uses a slightly different formula, but the common pattern is:
There's also usually a floor — a minimum dollar amount (often $25–$35) that applies when the percentage calculation comes out lower. Some issuers instead use a formula like "interest + fees + 1% of principal," which pays the loan down slightly faster. Your cardholder agreement spells out the exact method.
This calculator uses the most common model — a percentage of the balance with a floor:
Minimum Payment = max(Floor, Balance × Min%)
Monthly Interest = Balance × (APR ÷ 12)
Goes to Principal = Minimum Payment − Monthly Interest
where Floor is typically $25–$35, Min%is usually 1%–3%, and APR ÷ 12 converts the annual rate to a monthly rate. This is the formula the calculator above applies to your numbers in real time.
This is the part that surprises people. Here is a worked example using this calculator's default values — a $5,000 balance at 19.99% APR with a 2% minimum payment:
In other words, about 83% of your payment vanishes as interest, and just 17% reduces what you owe. At that rate it takes decadesto pay off — and that's assuming you never charge another dollar. If your payment is at or below the monthly interest, the balance never drops at all. You can verify every number above by entering $5,000 / 19.99 / 2 into the calculator.
Minimum payments used to be around 5% of the balance. In the 2000s, regulators pushed issuers to raise minimums so consumers could actually pay off debt, and many moved to the current ~1%–3% plus interest model. That formula still extends repayment over many years — but it guarantees the loan is technically repayable, which satisfies the rules. From the bank's perspective, a longer repayment schedule means more interest income; from yours, it means thousands of dollars in avoidable interest. The system is legal, but the only protection that truly helps you is paying more than the minimum.
Every dollar you pay above the interest goes 100% to principal. The effect compounds: as the principal shrinks, next month's interest shrinks too, so even more of your payment goes to principal. This is the mechanism that makes small extra payments so powerful.

The Credit Card Minimum Payment Calculator lets you figure out credit card minimum paymentinstantly, without reaching for a spreadsheet or doing the math by hand. Whether you're planning a budget, checking a loan, or working through homework, the tool applies the correct formula behind the scenes and shows the result the moment you enter your numbers.
Unlike a static chart or table, this calculator adapts to your exact inputs. You can adjust any value and see the outcome update in real time, which makes it easy to compare scenarios — for example, "what if the rate were 1% lower?" or "what if I paid an extra $50 a month?"
Common uses: people reach for this tool when they need to find a how is minimum payment calculated, credit card minimum payment formula, minimum payment vs interest, or how long paying minimum payment.
Browser-based tools like this one have a few real advantages over installed software or manual methods:
The Credit Card Minimum Payment Calculator is based on the following formula:
Min payment = max( balance × min%, fixed floor )
Variables: Min payment = Minimum payment due ($) balance = Current card balance ($) min% = Percentage of balance the issuer charges (often 1-3%, as a decimal) fixed floor = Smallest dollar amount the issuer will accept ($)
Issuers charge the larger of a small percentage of the balance (often 1–3%) and a fixed floor (e.g. $25). Interest is then added on the remaining balance until it is paid off.
Worked example: Step 1: balance = $1,200, min% = 2% → 1,200 × 0.02 = $24. Step 2: fixed floor = $25. Step 3: max(24, 25) = $25. Result: the minimum payment is $25. If the balance were $3,000, 2% would be $60, so the percentage would win and the minimum would be $60.
