How Credit Card Minimum Payments Are Calculated and How Long They Take to Pay Off a Balance
October 29, 2026
The minimum payment on a credit card is the smallest amount you must pay to keep the account in good standing. Issuers set it with a formula, often the greater of a flat dollar amount (such as $25 or $35) and a percentage of the balance (commonly 1%) plus that month's interest and fees. Because the minimum includes the interest, but only a small share of principal, a balance can take decades to pay off.
Consider a $5,000 balance at a 24% APR with a minimum of 1% of the balance plus interest. In the first month, interest is $100 (2% of $5,000), and 1% of the balance is $50, so the minimum is $150, of which only $50 reduces the balance.

As the balance falls, the minimum falls with it, because 1% of a smaller balance plus smaller interest is a smaller payment. The result is a long tail. Paying the formula minimum each month on the $5,000 balance, with no new purchases, takes 234 months, or 19.5 years, and costs $8,887 in interest, nearly 1.8 times the original balance. The total paid is $13,887.
In contrast, paying a fixed $150 a month (the first month's minimum) clears the same balance in 56 months, under 4 years and 8 months, with total interest of $3,322. Fixing the payment at the initial minimum saves $5,565 and over 14 years.
| Payment strategy on $5,000 at 24% APR | Time to pay off | Total interest |
|---|---|---|
| Minimum formula (1% + interest) | 19.5 years | $8,887 |
| Fixed $150 a month | 4 years 8 months | $3,322 |
| Fixed $200 a month | 3 years | $2,001 |
| Fixed $300 a month | 1 year 9 months | $1,143 |
The Statement Disclosure
In the United States, credit card statements must include a minimum-payment warning showing how long it would take to pay off the balance if you paid only the minimum and the total cost, and the monthly payment needed to pay off the balance in 36 months. Use that 36-month figure as a target if you can. For $5,000 at 24%, the 36-month payment is about $196, and total interest would be about $2,060. These disclosures help you see the cost of the minimum path.
How to Escape the Minimum Trap
Pay a fixed amount above the minimum, rounding up to a round number. Use windfalls, such as tax refunds, to make lump-sum payments. Move the balance to a lower-rate option, such as a 0% transfer card or a fixed-rate personal loan, if the fees and terms make sense. Stop using the card for new purchases while paying down the balance, since new charges add to the debt. Automate payments so that you never miss one, which would trigger late fees and penalty rates. If you cannot afford more than the minimum, contact the issuer about hardship programs or a nonprofit credit counselor.
Why Issuers Design It This Way
Low minimums keep customers current and borrowing for longer, which earns the issuer more interest. Regulators have required that the minimum cover at least interest and fees plus some principal, so that balances do not grow. Understand that a low minimum is not a recommendation of how much to pay.
Frequently Asked Questions
How is the minimum credit card payment calculated?
Typically the larger of a flat amount and about 1% of the balance plus interest and fees.
How long does it take to pay off a card with minimum payments?
Often many years. $5,000 at 24% APR takes nearly 20 years under a 1% plus interest formula.
Is it better to pay a fixed amount?
Yes. A fixed payment pays off the balance far faster and saves interest.
What does the 36-month figure on my statement mean?
The payment that would clear your balance in three years, ignoring new charges.
Do minimum payments reduce my balance?
Only slightly, since most of the payment covers interest.
