Credit Card Minimum Payment Calculator

What the minimum payment is

The minimum payment is the smallest amount a card issuer accepts in a billing cycle without marking the account late. Pay it and the account stays current. Skip it and the issuer can charge a late fee, apply a penalty rate, and report the missed payment to the credit bureaus.

The number on the statement is not a suggestion about how to pay off the balance. It is a floor written into the card agreement, built so the account keeps generating interest. On a typical card the minimum covers the interest charge for the month plus a sliver of principal, which is why a balance paid this way can outlast the furniture, the vacation or the emergency that created it.

The Consumer Financial Protection Bureau requires card issuers to print a minimum payment warning on every statement, showing how long the balance takes to clear at the minimum and how much interest that path costs. The disclosure exists because the arithmetic is unfavorable, and because most cardholders never run the numbers themselves. The calculator on this page runs them for you, and the sections below show exactly where each dollar of a minimum payment goes.

How issuers calculate the minimum

Card issuers use one of a handful of formulas, and the card agreement names which one applies. The three structures below cover nearly every card on the market.

Whichever formula applies, the floor matters more than people expect. When the balance is small the percentage formula produces a payment below the floor, so the floor takes over. When the balance is very large the percentage method can produce a payment that grows every month, which is why some issuers cap it or switch to the 1 percent plus interest structure.

Interest is charged on the average daily balance at the card's annual percentage rate divided by 12. On a card with a 21 percent APR, the monthly rate is 21 / 12 = 1.75 percent. A $5,000 balance therefore accrues 5,000 x 0.0175 = $87.50 of interest in the first month. That interest gets paid first inside any minimum, and only what remains touches the principal.

Worked example: $5,000 at 21 percent APR

Take a $5,000 balance on a card with a 21 percent APR, no fees, and a minimum defined as the greater of $35 or 1 percent of the balance plus interest. The monthly interest rate is 0.21 / 12 = 0.0175.

Month 1: interest = 5,000 x 0.0175 = $87.50. The 1 percent part is 5,000 x 0.01 = $50.00. The minimum is 50.00 + 87.50 = $137.50, which sits above the $35 floor, so $137.50 is due. Of that payment, $87.50 covers interest and $50.00 reduces the balance to $4,950.00.

Month 2: interest = 4,950 x 0.0175 = $86.62. The 1 percent part is $49.50. The minimum is 49.50 + 86.62 = $136.12. The balance falls to 4,950.00 - 49.50 = $4,900.50.

The pattern is now visible. Each month the payment shrinks a little, the interest portion shrinks a little, and the principal portion shrinks by the same amount. Nothing accelerates. Paid this way the $5,000 balance takes 195 payments, a little over 16 years, and generates $7,290.89 of interest. The cardholder pays $12,290.91 in total for $5,000 of purchases.

Near the end the percentage formula drops below the $35 floor and the floor takes over, which is why month 194 shows a flat $35 payment. The last payment, month 195, is only $15.83 because it clears the small remaining balance in full. The floor guarantees the account never stalls on pure percentage arithmetic.

What a fixed payment changes

The single most effective change a cardholder can make is to stop letting the payment shrink. Take the first minimum, $137.50 in the example above, and pay exactly that amount every month regardless of what the statement says.

With a fixed $137.50 payment the same $5,000 balance at 21 percent APR clears in 59 months, just under 5 years, with $3,017.89 of total interest. Compare that to 195 months and $7,290.89 of interest at the declining minimum. Holding the payment flat saves $4,272.98 and removes 136 payments from the schedule.

The reason is mechanical. A fixed payment sends the same dollars to principal every month while the interest charge keeps falling as the balance drops, so an ever larger slice of each payment attacks the balance. The declining minimum does the opposite: it shrinks in lockstep with the balance, so the principal reduction shrinks too.

Push the payment higher and the payoff curve steepens further. A fixed $187.50 payment, $50 more per month, clears the same balance in 37 months with $1,794.17 of interest. That extra $50 per month saves another $1,223.72 over the fixed minimum and cuts the payoff time by 22 more months.

How the amortization of a card differs from a loan

A car loan or mortgage amortizes on a fixed schedule: same payment every month, known end date, and a principal share that grows over time. A credit card has none of those properties when paid at the minimum. The payment recalculates every month from the current balance, so there is no fixed end date built into the product.

On an amortizing loan the last payment is nearly all principal. On a card paid at the minimum the last payments are often floor payments of $25 or $35, and the interest share stays small only because the balance itself has finally become small. The shape of the payoff curve is the mirror image of a loan.

Two behaviors make card amortization worse than the base case. New purchases added to a card that already carries a balance extend the payoff further, because most issuers apply payments to the balance with the lowest APR first, as required by the CARD Act of 2009, but the new purchases still accrue interest from the day they post. Cash advances usually carry a higher APR and no grace period, so they generate interest immediately and sit at the front of the payoff queue only if their rate is the lowest.

The practical takeaway is to stop charging on a card you are trying to clear. A card in a payoff plan behaves like a loan only when the balance is frozen and the payment is held flat or higher.

The rules behind the statement warning

Federal rules shape what appears on every card statement. The Credit Card Accountability Responsibility and Disclosure Act of 2009, usually called the CARD Act, directed the Federal Reserve to write rules on minimum payment disclosures. The rules require a warning box showing three things: how long the balance takes to pay off making only minimum payments, the total interest cost of that path, and the monthly payment needed to clear the balance in 36 months with the associated interest total.

The Consumer Financial Protection Bureau now supervises card issuers for compliance with the CARD Act and handles complaints about minimum payment disclosures, late fees and penalty rates, and the Federal Trade Commission publishes consumer guidance on credit card costs. Late fee amounts are capped by Regulation Z, and a penalty APR cannot be applied to an existing balance unless the account is more than 60 days past due.

Some issuers also list the 3 year payoff payment on the statement alongside the minimum. That 36 month figure is a useful anchor because it corresponds to a payment roughly two to three times the minimum on a mid size balance, and the interest saved at that payment level is exactly what the fixed payment comparison in this article shows.

The rules do not require the issuer to make the minimum generous. The formulas remain set by the card agreement, and the floor amounts have risen over the years from $10 and $15 in earlier decades to $25 and $35 today, but the structure, a percentage plus interest with a floor, is unchanged.

How minimum payments interact with credit scores

Paying the minimum keeps the account current, which protects the payment history component of a credit score. Payment history is the largest single factor, so on time minimum payments are far better than missed payments even though the balance barely moves.

The tradeoff shows up in credit utilization, the ratio of the card balance to the card limit. A $5,000 balance on a $6,000 limit is 83 percent utilization, which scores poorly regardless of whether every minimum was paid on time. Utilization is the second largest factor, and scores generally improve as the ratio falls below 30 percent.

So the minimum payment path protects one factor while quietly harming another. The account never goes delinquent, but the high balance keeps the utilization ratio high for the 16 years the payoff takes. Paying above the minimum attacks both goals at once: the balance falls faster, the utilization falls with it, and the payment history stays clean.

There is no penalty for paying the full statement balance every month, and cardholders who do so pay no interest at all on purchases because of the grace period. The minimum exists for the issuer's benefit, not as a recommended amount.

Strategies to escape the minimum payment trap

The arithmetic in the worked example points to a short list of moves that change the outcome.

First, freeze the payment. Note the current minimum and pay that exact amount every month even as the statement number falls. The example above shows $4,272.98 of interest savings from this single change.

Second, round up. Adding a fixed $25 or $50 on top of the minimum compounds the effect. The extra $50 per month in the example cut 22 months and $1,223.72 more in interest.

Third, target the highest APR balance first if several cards carry debt, the avalanche method, or clear the smallest balance first for a psychological win, the snowball method. Either way the key is directing extra dollars to one card while paying minimums on the rest.

Fourth, check whether a balance transfer to a card with a 0 percent introductory APR makes sense. The transfer fee is typically 3 to 5 percent, so a $5,000 transfer costs $150 to $250 up front, but 12 to 21 months of zero interest on a balance that would otherwise accrue $87.50 per month can outweigh the fee. The offer only works if the balance is paid down before the promotional rate expires.

Fifth, call the issuer and ask for a lower rate. Issuers sometimes grant rate reductions to cardholders with a history of on time payments, and every point of APR removed lowers the interest portion of every future minimum.

The table below collects the key numbers from this page for quick reference, all computed with the standard formulas and matching the calculator above.

Every figure traces back to the same three inputs: balance, APR and the minimum payment formula. Change any one and the schedule changes, which is what the calculator is for. The one constant across every scenario is the ordering inside the payment: interest first, fees second, principal last.
