Credit card payoff calculator

Why your minimum payment barely moves the needle

Here’s something most people don’t realize about credit cards until they actually run the numbers: your minimum payment isn’t designed to pay off your balance in any reasonable amount of time. It’s designed to keep the account current while the interest does most of the work.

Most issuers set the minimum at somewhere around 2% of your balance, with a dollar floor (often $25 or so) for smaller balances. That percentage shrinks every month as your balance shrinks, which sounds like progress but actually means the payment gets smaller right as it should be getting more aggressive. On a $5,000 balance at 24.9% APR, paying only the minimum can stretch the payoff out past 20 years and cost more in interest than the original purchase amount.

A fixed payment works completely differently. You pick a number and pay that same amount every single month, even as the balance drops. That consistency is what actually kills off debt — the payment doesn’t shrink alongside the balance, so more of it goes toward principal each month.

A number worth sitting with

If your planned fixed payment is close to (or below) what you’re paying in interest each month, it won’t matter how disciplined you are — the balance won’t move. This calculator flags that specifically, because it’s a more common trap than people expect. Someone commits to “paying more than the minimum,” picks a number that sounds reasonable, and doesn’t realize it’s barely covering the interest charge.

A few things worth knowing before you use this

Your card’s actual minimum payment formula is on your statement — usually in the fine print near the payment due date, sometimes described as something like “1% of balance plus interest and fees.” It varies by issuer, so don’t assume the 2% default here matches your card exactly; adjust it if you know your real number.

Also worth saying: if you’re carrying a balance at 20%+ APR and also have cash sitting in a regular savings account earning a fraction of a percent, the math almost always favors throwing that cash at the card first. There are exceptions (upcoming expenses, no emergency cushion at all), but as a general rule, guaranteed 20%+ “return” from debt payoff beats almost anything else available to an average saver.

Is it ever smart to only pay the minimum? Sometimes, temporarily — if cash flow is genuinely tight and the alternative is missing a payment entirely, minimum payments keep the account in good standing while you regroup. Just don’t mistake “temporarily necessary” for “a plan.”

Will a balance transfer help? It can, especially a 0% intro APR offer, but read the transfer fee (typically 3-5% of the balance) and the length of the promotional period before assuming it’s automatically better than what you’re doing now.
