A reader's calculator · The minimum payment trap, in numbers

A $5,000 balance at 22% APR, paying the interest-plus-1% minimum, costs $8,100 in interest over 19 years, 2 months.

Not because you are bad with money. Because the formula is built to keep you paying. Type your numbers below and see exactly what your card is doing.

The middle column locks the first month's minimum and never lets it shrink. The right column is the fixed monthly payment that clears the balance in three years. Both beat the minimum-only path by years.

Section II

Why the minimum is designed to keep you paying for a decade

The minimum payment is not a recommendation. It is the smallest amount your issuer will accept without marking the account late. As your balance falls, the minimum falls with it. Less goes to principal each month, more of every payment is interest, and the loan stretches across years that compound the bank's earnings while compressing yours.

  1. The minimum is a percentage of your current balance. At 2%, a $5,000 statement triggers a $100 payment. The lower your balance gets, the lower this number gets.
  2. Interest is calculated daily, not monthly. The bank applies the daily periodic rate to your average daily balance. At 22% APR, every $1,000 you carry costs about $0.60 a day. A balance you carry for the full month costs about $18 per $1,000.
  3. As the minimum shrinks, principal reduction shrinks faster. By year five on a $5,000 balance, your minimum has fallen to roughly $76 per month. Of that, about $70 is interest. About $6 is principal. The number on the statement looks like progress. The math is treadmill.
  4. The fix is not paying more. It is not paying less. Lock the first month's minimum and never let it shrink. That single behavioural change shaves years off the timeline at zero extra dollars committed up front.

Section V

The five most-asked questions

For the full set, see the FAQ.

How is the minimum payment on a credit card calculated?
Most US issuers use one of two formulas. The flat-percentage method takes 1% to 3% of your balance (most commonly 2%) with a floor of $25 to $35. The interest-plus-principal method takes all monthly interest plus 1% of the balance. The exact terms are disclosed in your cardholder agreement, which you should always check.
How long does it take to pay off $5,000 paying only the minimum?
At 22% APR using the interest-plus-1% formula (with the standard $25 floor), $5,000 takes about 19 years 2 months to clear and costs roughly $8,100 in interest, so the original $5,000 of spending becomes $13,100 paid back. On the flat 2% method at the same APR, the math runs into negative amortisation: the minimum barely covers interest, so the balance drags out for decades. Read your cardholder agreement to see which formula your card uses.
Will my credit score drop if I only pay the minimum?
Paying the minimum on time keeps the account current and protects your payment history (35% of your FICO score). The bigger score drag is utilisation: a high balance against your credit limit suppresses your score, and minimum payments barely move the balance. So the minimum protects payment history but costs you on utilisation.
What is the minimum payment on a $10,000 credit card balance?
At a 2% flat method: $200. At interest-plus-1% on a 22% APR card: about $283 (the $183 of monthly interest plus $100 of principal). Both are above the typical $25 to $35 floor, so the floor does not apply at this balance.
How much do I save by paying $50 extra each month?
On $5,000 at 22% APR using the interest-plus-1% method, an extra $50 a month cuts the payoff from about 19 years 2 months to about 5 years 7 months and saves roughly $5,270 in interest. Extra payments are most powerful early because they reduce the principal that generates future interest.
