Why credit card debt is so sticky
Every month the card adds interest on whatever you still owe, and your payment has to cover that interest first before any of it touches the balance. This calculator works out how many months a fixed monthly payment takes to clear the card, and how much interest you hand over on the way. Seeing the total interest in plain numbers is often the push people need to pay more than the minimum.
The trap is the minimum payment. It is deliberately set just high enough to cover most of the interest and a sliver of the balance, which is why a card can take decades to clear if you only ever pay the minimum. The gap between your payment and the monthly interest is the only part that actually reduces what you owe.
Two examples
A 5,000 balance at 18% APR with 200 a month clears in about 32 months and costs roughly 1,300 in interest. Not cheap, but manageable.
Take the same 5,000 at 18% but pay 120 a month instead. Now it drags on for more than four years and the interest climbs well past 2,000. You paid less each month and far more in total. That is the whole story of credit card debt in two lines.
How to clear it faster
- Pay more than the minimum, always. Every extra amount skips the interest and goes straight to the balance.
- Attack the highest APR card first if you have several. That is where interest is doing the most damage.
- Look into a lower-rate balance transfer, but only if you will clear it before any promotional rate ends.
The one thing to watch
If your monthly payment is less than or equal to the monthly interest, the balance never goes down and the card never pays off. The calculator will flag this. When it happens, the only fix is to pay more each month or to lower the rate, because at that point you are renting the debt, not repaying it.
Frequently asked questions
Should I pay off the highest APR card first?
Usually yes. Clearing the most expensive debt first saves the most interest overall, an approach often called the avalanche method.
Will a balance transfer help?
It can, if the new rate is much lower and you clear the balance before any promotional period ends. Watch for transfer fees.
Why does it say it never pays off?
If your monthly payment is less than or equal to the monthly interest, the balance never falls. Increase the payment.
Does it assume a fixed payment?
Yes, the same amount every month. Paying more shortens the time and cuts interest sharply.
Is APR the same as monthly rate?
No. The monthly rate is the APR divided by 12. The calculator converts it for you.
