The real cost of paying only the minimum
The minimum payment is the single most expensive habit in personal finance — and it is designed to be. This minimum payment calculator shows you exactly why: enter your balance, interest rate and your card's minimum-payment formula, and it reveals how many years the balance lingers and how much interest you hand over if you only ever pay the minimum. Then it compares that against paying a fixed amount, so you can see the difference in plain dollars.
Why the minimum keeps you stuck
Credit card minimums are usually calculated as a small percentage of your balance — commonly 1% to 3% — with a floor of around $25 to $35. Because the payment is a percentage of the balance, it shrinks every month as the balance falls. Early on, almost all of that payment is swallowed by interest, leaving only a few dollars to reduce what you actually owe. The result is a slow grind that can stretch a few thousand dollars of debt across a decade or more. The calculator highlights this directly by showing how little of your very first minimum payment goes toward the balance.
How paying a fixed amount changes everything
The fix is simple: pay a fixed amount each month instead of the shrinking minimum. When your payment stays constant, every dollar above the interest goes straight to principal — and as the balance drops, an even larger share attacks the principal, accelerating payoff. Paying just a little more than the minimum can cut years off the timeline and save thousands in interest. Try it above: compare the minimum against a fixed $200 a month on a $5,000 balance and watch both the time and the interest collapse.
Turn the insight into a plan
Once you have seen the gap, lock in a fixed payment and automate it so the money leaves your account before you can spend it. If the fixed amount the calculator suggests feels out of reach, our affordability calculator helps you find room in your budget, and the credit card payoff calculator lets you test different payment amounts to land on a date that works. If you carry several cards, the snowball vs avalanche tool shows which to attack first.
One number to remember
If you take away one thing, make it this: the minimum payment is the bank's plan for your money, not yours. Any fixed payment above the minimum is a raise you give your future self. Even an extra $25 or $50 a month changes the math dramatically — and the sooner you start, the more you keep.
