Credit Card Minimum Payment Calculator
See how many years and how much interest you pay if you only make the minimum, and how much a steady fixed payment saves.
Enter a balance and APR to see how long the minimum really takes.
What your result means
The catch with minimum payments is that the minimum is usually a percentage of your balance, so as the balance falls, the required payment falls with it. You end up paying less and less each month, which drags the payoff out for years. Most of each early payment goes to interest, not principal. The single most effective fix is to stop letting the payment shrink: pick an amount and keep paying it.
How issuers calculate the minimum
There are three common methods, and your cardholder agreement says which one applies:
- Flat percentage of balance: typically 2% to 4% of what you owe. On a $5,000 balance at 2%, that is $100.
- 1% of balance plus interest and fees: a smaller slice of principal plus that month's interest. This is common on modern cards and produces a higher, more honest minimum.
- Dollar floor: a flat amount like $25 to $35 that kicks in when the percentage comes out too low. If your balance is under the floor, you pay the full balance.
One trap worth knowing: with a flat 2% minimum on a card at 24% APR, the minimum barely exceeds the interest, so the balance can take over 100 years to clear. This calculator flags that case instead of pretending it pays off.
The minimum payment trap, in real numbers
A $5,000 balance at 24% APR, using the 1%-plus-interest method:
- Time to pay off at the minimum: about 201 months, or roughly 17 years
- Total interest: about $8,442 (more than the balance itself)
- First month's minimum: $150
Now freeze that $150 as a fixed payment instead of letting it shrink. The same balance clears in about 56 months with roughly $3,322 in interest. That one change saves about 12 years and over $5,000. Same starting payment, wildly different outcome.
Minimum payment on common balances
Starting minimums and payoff times using the 1%-plus-interest method at 24% APR (a $35 floor applies):
| Balance | First minimum | Payoff at minimum only |
|---|---|---|
| $1,000 | $35 (floor) | about 43 months (3.6 years) |
| $3,000 | about $90 | about 15 years |
| $30,000 | $900 | about 379 months (32 years) |

Frequently asked questions
How is a credit card minimum payment calculated?
Issuers use a flat percentage of your balance (often 2% to 4%), or a smaller percentage of principal (usually 1%) plus that month's interest and fees. Both have a dollar floor, commonly $25 to $35, and if your balance is under the floor you pay it in full. Your cardholder agreement says which applies.
Why do minimum payments take so long?
The minimum is a percentage of the balance, so it shrinks as the balance shrinks. Less goes toward the debt each month, stretching payoff over years or decades on a large balance.
What is the minimum payment on a $3,000 credit card?
Around $85 using 1% plus interest at 22% APR, or about $60 at a flat 2%. A $25 to $35 floor applies when the percentage is lower.
Does paying only the minimum hurt my credit score?
Paying on time protects your payment history, the largest scoring factor. The real risk is the high balance that builds up, since utilization matters too. Paying more helps both.
How do I escape the minimum payment trap?
Freeze your payment. Keep paying at least the first month's minimum as a fixed amount instead of letting it drop. That alone can cut years off payoff and save thousands.
