Why minimum payments cost so much
Your credit card's minimum payment is designed to keep your account in good standing, not to get you out of debt. Because it's calculated from your balance, it shrinks as the balance shrinks. You pay down a little principal each month while interest keeps accruing on everything that's left, so the payoff stretches out for years and the interest adds up to a large share of what you originally borrowed.
How the calculator works
Each month it adds interest (APR ÷ 12 × balance), works out the minimum using the formula you select, and subtracts that payment, never charging less than your floor and never more than you owe. It repeats until the balance reaches zero.
"1% + interest" minimum = 1% × balance + monthly interest (at least the floor)
"Percentage" minimum = % × (balance + interest) (at least the floor)
It then compares two alternatives: the fixed payment that clears the card in exactly three years (the figure US statements show), and any fixed monthly payment you choose.
Worked example
Take a $6,000 balance at 22.99% APR with a "1% of balance + interest" minimum and a $25 floor.
- Minimum payments only: the first payment is about $175, then it falls month by month. Paying off the card takes about 20 years and 10 months and costs about $10,400 in interest, far more than the original balance.
- Three-year plan: about $232 a month clears it in 36 months with roughly $2,360 of interest.
- Fixed $200 a month: debt-free in about 3 years and 10 months, with about $3,010 of interest. That saves around $7,400 compared with paying only the minimum.
The key move is to stop letting the payment shrink. Even keeping your payment at the size of your first minimum, instead of following it down, makes a dramatic difference.
How to pay off your card faster
- Pick a fixed payment and automate it. Set up autopay for a fixed amount above the minimum so the plan runs without willpower.
- Ask for a lower APR. Card issuers sometimes agree, especially for customers with a good payment history. Change the APR above to see what a few points are worth.
- Consider a balance transfer. A 0% introductory offer can stop interest for a year or more, but watch transfer fees (often 3% to 5%) and the rate after the promotion ends.
- Stop new charges. New spending on the card works against your payoff plan.

Frequently asked questions
How is a credit card minimum payment calculated?
It depends on your card agreement. A common US formula is 1% of the balance plus that month's interest and any fees, with a floor of around $25 to $40. Other issuers use a flat percentage of the balance, often 2% to 3%. Your statement and cardholder agreement show your card's exact formula.
Why does paying the minimum take so long?
Minimum payments shrink as your balance shrinks, so you're always paying off only a small slice of principal while interest keeps accruing on the rest. Much of each payment goes to interest, which is why a few thousand dollars can take well over a decade to clear.
What does the 3-year payment on my statement mean?
Under the US CARD Act, statements must show how long it would take to pay off your balance with minimum payments only, and the monthly payment needed to pay it off in about three years. The calculator shows the same 3-year figure for the numbers you enter.
Is it bad to only pay the minimum?
Paying at least the minimum on time protects your credit and avoids late fees, so it's far better than missing a payment. But as a long-term strategy it's very expensive. Even a modest fixed payment above the minimum can cut years and thousands of dollars of interest.
