Debt payoff toolkit
This minimum payment trap calculator shows what minimum only payments really cost: decades and thousands in interest, versus a fixed payment on the same balance. The side by side comparison is the wake up call.

Most US cards set the minimum as the greater of 2% of the balance or $25. That sounds reasonable until you do the math. On a $2,800 balance at 19.99%, the first minimum is about $56, and roughly $47 of it is interest. You pay $56 and owe $2,791. Next month the minimum is just as small, and the interest nearly as big. The balance barely moves, and because the minimum shrinks as the balance shrinks, the payoff stretches into decades. The minimum is engineered to keep the account current, not to set you free.
The numbers prefilled above: $2,800 at 19.99%, minimums only. The minimum payment trap calculator says 27 years and 4 months, $8,478.30 in interest, $11,278.30 total. You repay the balance four times over. Now the fixed payment: $120 a month clears it in 2 years and 6 months with $774.93 of interest. Same debt, same rate. The only difference is refusing to let the payment shrink. The trap is not the rate. The trap is the shrinking payment.
Pick a fixed payment you can sustain and automate it. Never pay just the minimum again unless it is a true emergency month. If you carry several cards, run them through our debt snowball calculator to get the attack order, and read how to get out of credit card debt for the full step by step plan. The escape is always the same shape: fixed payment, automatic, no new charges.
It simulates the standard card minimum, the greater of 2% of the balance or $25, month by month. As the balance shrinks, so does the minimum, which stretches the payoff over decades. Then it runs your fixed payment on the same balance so you can compare the two timelines side by side.
Because the minimum shrinks with the balance. Early on, most of it covers interest, not principal. Later, the payment itself gets tiny, so progress crawls. The formula is designed around what keeps the account current, not what gets you free. That is the trap this minimum payment trap calculator exposes.
Most US cards use the greater of 2% of the balance or $25. Some use 1% plus interest and fees. Either way it is a small fraction of the balance, which is exactly why minimum only payoffs take decades on large balances.
Dramatically. On the example above, a fixed $120 payment finishes in 2 years and 6 months versus 27 years and 4 months on minimums, saving $7,703.38 in interest. The fixed payment does not shrink, so every month hits harder than the last.
No. Paying more helps: balances fall faster, utilization drops, and on time payments keep building history. There is no penalty for paying above the minimum, ever.
