The formula is usually 1 to 3 percent of your balance, plus interest and fees
Credit card companies calculate your minimum payment using a straightforward formula: they take a percentage of your current balance (typically 1 to 3 percent), then add any interest that has accrued since your last statement and any fees you owe. The exact percentage varies by card issuer and sometimes by the type of card, but the math is the same across the industry. A $5,000 balance at a 2 percent minimum might result in a $100 payment, plus whatever interest and late fees explore.
The percentage itself is set by the card issuer, not by law. Visa and Mastercard have recommended minimums, but they do not enforce them. Your bank or credit card company decides what percentage to use, and they are required to disclose it in your cardholder agreement. Some issuers use 1 percent, others use 2 or 3 percent. A few use a tiered system where the percentage changes based on how much you owe.
The interest portion is what makes the minimum payment harder to predict. Your card issuer calculates interest daily based on your daily balance and your annual percentage rate (APR). If you carry a balance, the interest compounds, meaning you pay interest on interest. This is why the minimum payment can stay roughly the same month to month even though your balance is not dropping—the interest keeps growing.
Key Takeaways
- The minimum payment is a percentage of your balance (usually 1 to 3 percent) plus accrued interest and any fees you owe.
- Card issuers set their own percentage and must disclose it in your cardholder agreement; there is no federal minimum percentage requirement.
- Interest is calculated daily and added to your minimum each month, which is why paying only the minimum keeps you in debt longer.
- If you miss a payment, late fees are added to your next minimum, increasing what you owe.
Where the percentage comes from
Your card issuer chooses the percentage used to calculate your minimum, and they decide this when they design the card product. A card marketed as "low minimum payments" might use 1 percent of your balance. A premium card or one aimed at people with higher credit scores might use 2 or 3 percent. The issuer is betting on how much money they will make from interest if you carry a balance, and they set the percentage to balance that against the risk that you will stop paying altogether.
The percentage is disclosed in your cardholder agreement, usually in a section titled "Minimum Payment" or "How We Calculate Your Payment." If you have lost your agreement, you can request it from your card issuer or find it on your online account. The agreement also explains whether the percentage changes if your balance drops below a certain amount—many cards use a flat dollar minimum (like $25) if your balance is very small.
Visa and Mastercard recommend that issuers use at least 1 percent of the balance plus interest and fees, but this is a recommendation, not a rule. Some issuers go higher to encourage faster repayment. Others stay at 1 percent because it keeps monthly payments low and customers more likely to keep the card active.
How interest gets added to your minimum
Interest is calculated on your daily balance, not your statement balance. Here is how it works: each day, your card issuer looks at what you owe. They multiply that by your daily interest rate (your APR divided by 365). They do this every day, and at the end of your billing cycle, they add up all those daily interest charges. That total is what appears on your statement as "interest charged" and gets added to your minimum payment.
If you pay your full statement balance by the due date, you owe no interest and your minimum payment is just the percentage of the balance you paid off. But if you carry a balance forward, interest accrues on that remaining balance every single day until you pay it off. This is why people who pay only the minimum often feel stuck—the interest keeps growing, and the minimum payment barely covers it.
The interest rate itself (your APR) is set by the card issuer based on your credit score and creditworthiness when you open the account. It can change if you miss payments or if the issuer decides to raise rates, but they must give you notice before doing so. The higher your APR, the more interest gets added to your minimum each month.
What happens when fees are involved
If you have incurred any fees—a late payment fee, a returned payment fee, or a cash advance fee—those are added directly to your minimum payment. A late fee is typically $25 to $40 for the first late payment and $35 to $40 for subsequent ones within six months. A returned payment fee (when a check or electronic payment bounces) is usually $25 to $40. These fees are added to your next statement and become part of what you owe.
Once a fee is on your account, it stays there until you pay it. It does not disappear if you make your next payment on time. This is why a single missed payment can cause your minimum to jump unexpectedly—the fee gets added on top of the regular percentage-plus-interest calculation. Some card issuers will reverse a single late fee if you call and ask, especially if you have a good payment history, but they are not required to.
Why the minimum payment keeps you in debt
The minimum payment is designed to be affordable, not to pay off your debt quickly. If you owe $5,000 at 20 percent APR and pay only the minimum (let us say 2 percent of the balance plus interest), you will pay roughly $150 to $200 per month. At that rate, it will take you three to four years to pay off the balance, and you will pay $1,500 to $2,000 in interest alone. The card issuer makes money from that interest, so they have no incentive to set a higher minimum.
The math works against you because interest is calculated on your remaining balance. In the first month, most of your payment goes to interest, not principal. As your balance shrinks, the interest portion shrinks too, but slowly. This is why paying even slightly more than the minimum—say, 5 percent of your balance instead of 2 percent—can cut your payoff time in half and save you hundreds in interest.
How to find your card's minimum payment formula
Your cardholder agreement is the authoritative source. You can find it by logging into your online account and looking for "Account Documents," "Disclosures," or "Cardholder Agreement." If it is not there, call the customer service number on the back of your card and ask them to email or mail you a copy. They are required to provide it.
Your monthly statement also shows the calculation. Look for a section that says "Minimum Payment Due" and sometimes a line item that breaks down the percentage, interest, and fees. Not all statements show the breakdown, but the total minimum is always there. If you want to understand exactly how your issuer calculated it, you can ask customer service to walk you through the math on your specific statement.
Frequently Asked Questions
Can a credit card company change my minimum payment formula?
Yes, but they must notify you in advance. If your card issuer changes the percentage they use to calculate your minimum, they will send you a written notice at least 21 days before the change takes effect. You can usually find this information in the "Changes to Your Account Terms" section of your statement or in a separate letter.
What if my minimum payment is more than my balance?
This happens when fees and interest exceed the percentage-based minimum. For example, if you owe $200 but have a $35 late fee and $50 in interest, your minimum might be $85 or more. In this case, you owe the full amount of fees and interest plus whatever percentage applies to the remaining balance. You cannot pay less than the total.
Does paying the minimum hurt my credit score?
Paying on time protects your score, but carrying a balance—even if you pay the minimum—can lower it. Credit scoring models look at your credit utilization, which is how much of your available credit you are using. If you carry a balance, your utilization is high, and that counts against you. Paying the minimum on time is better than missing a payment, but paying the full balance is better for your score.
Why is my minimum payment higher this month?
The most common reasons are a late payment fee, a spike in interest (if your APR increased), or a larger balance than last month. If you made a late payment, the fee gets added to your next minimum. If your balance grew because you made new purchases, the percentage-based portion of your minimum grows too. Check your statement for the itemized breakdown of your minimum to see what changed.
Can I negotiate a lower minimum payment?
You cannot change the formula your card issuer uses, but if you are struggling to pay, you can contact them about a hardship program. Some issuers offer temporary payment reductions or modified payment plans if you explain your situation. These programs vary widely and are not may provide, but it is worth asking if you are having trouble making your minimum.
