Credit card minimum payments are typically calculated as 1% to 2% of the outstanding balance, with a hard floor of $25 or $35 depending on the issuer. The number is set just barely above the monthly interest accrual, which means the principal moves only a few dollars per month even at low balances. For most high-APR cards, the minimum is engineered so that following it leaves you in debt almost indefinitely.

The math is straightforward but the result is shocking when you trace it through. A $5,000 balance at 22% APR accrues roughly $92 per month in interest. A typical 2% minimum is $100. That means each month, $92 goes to interest and $8 goes to principal. At that rate, the balance falls by less than $10 a month while accruing more interest, and the payoff stretches into decades. Federal regulations require credit card issuers to disclose this on every statement — look for the 'Minimum Payment Warning' box that tells you how long the balance takes to pay off and how much total interest you pay if you only make the minimum.

The trap is particularly cruel for users who feel they are 'managing' their debt by reliably making the minimum each month. The credit score does not suffer because the payments are on time, the account stays in good standing, and there is no signal that anything is wrong — except that the balance is barely moving and the interest meter keeps running. Many users report being shocked when they finally look at the cumulative interest paid over a 5-10 year period.

Escaping the trap is mechanical. The minimum payment is the floor; anything above it goes 100% to principal because the minimum already covers the month's interest. Even a small extra payment ($25-50 a month) dramatically changes the payoff curve because of how compounding works in reverse — every dollar of principal eliminated stops accruing interest immediately, and that interest savings compounds across the remaining payoff schedule. The first extra dollars are worth multiples of the last.
