Credit Card Payoff Calculator (Minimum Payment Trap)
Enter your balance and APR, then compare what minimum payments really cost against a fixed monthly amount. You'll see the payoff date, total interest, and the gap between the two paths.

Minimums are a product, not a plan
The minimum payment formula (interest plus 1% of the balance) is engineered so the payment always covers slightly more than the interest. That keeps you current, and it keeps the balance alive for decades: as the balance falls, the required payment falls with it, so progress slows exactly when it should be speeding up. A $5,000 balance at 24% APR started at minimums doesn't reach zero for well over 15 years, and the interest along the way can rival the original balance. The card issuer designed that curve on purpose.
The fixed-payment trick
The escape is almost embarrassingly simple: freeze the payment. Take whatever this month's minimum is and keep paying that exact dollar amount until the balance hits zero. Because the payment no longer shrinks, every month a larger share hits principal, and the same $5,000 balance is gone in under five years instead of fifteen-plus. If you want a specific debt-free date, work backwards: try payments in the calculator until the timeline lands where you want it. Juggling several cards at once is the debt payoff calculator's job, and our snowball vs. avalanche guide covers which card to hit first. Watching the balance actually fall each month is the feedback loop that keeps a plan alive, which is exactly the kind of tracking Stoia automates.
Balance transfers in one honest paragraph
A balance transfer moves the balance to a card with a 0% intro APR, usually for 12 to 21 months, in exchange for a 3% to 5% fee added up front. It works for exactly one kind of person: someone who divides the balance by the number of intro months, pays that fixed amount on schedule, and stops charging on both cards. For everyone else it tends to become two balances instead of one. It also opens a new account and shifts your credit utilization around, so time it away from any mortgage or auto loan application.
Frequently asked questions
How is a credit card minimum payment calculated?
Most issuers charge the month's interest plus 1% of the balance, with a floor around $25. On a $5,000 balance at 24% APR that works out to roughly $150 to start. The exact formula varies by issuer, but interest plus 1% is the industry-typical version and it's what this calculator uses.
Why does paying only the minimum take so long?
Because the payment shrinks as the balance shrinks. Each month you pay slightly less, so the balance falls slower and slower. A $5,000 balance at 24% APR takes well over a decade of minimum payments, and the early payments are almost entirely interest.
How do I pay off a credit card faster?
Fix the payment. Keep paying the same dollar amount every month instead of the declining minimum, and the timeline collapses from decades to a few years. Anything extra on top goes straight to principal and shortens it further.
Do minimum payments hurt my credit score?
Paying the minimum on time keeps the account current, so there is no late-payment damage. But carrying a high balance keeps your credit utilization high, which weighs on your score month after month until the balance comes down.
Is a balance transfer worth it?
It can be, if you treat the 0% intro window as a payoff deadline rather than a reset. You'll typically pay a 3% to 5% transfer fee up front, and the math only works if you pay the balance down hard during the intro period instead of adding new charges.
