Paying £150 a month clears the £3,000 balance in the time shown, costing about £793 in interest along the way. Paying a little more each month cuts both sharply.

The maths that keeps people in debt
Credit cards charge interest on your remaining balance every month. Pay only a little over that interest and the balance barely moves, which is how a few thousand pounds can take years and cost as much again in interest. Paying a fixed, higher amount each month flips it, more of every payment goes on the debt itself.
Whether you are looking for a credit card payoff calculator, a credit card repayment calculator or simply a credit card payment calculator, this is the same sum: how long the balance takes to clear, and what the interest costs you on the way.
Ways to clear it faster
- Pay a set amount, not the minimum. The minimum shrinks as your balance does, dragging repayment out.
- Consider a 0% balance transfer. Pausing interest means every pound reduces the debt, just mind the fee and the end date.
- Tackle the priciest debt first. Clearing the highest-APR card saves the most interest.
Clearing card debt also lifts your credit score by lowering your utilisation. It is worth checking your credit report so you can see exactly what lenders see.
Pay a bit more, save a lot
How much you pay each month is the single biggest lever. Here is the same £3,000 balance at 24.9% APR, cleared at three different monthly payments:
| You pay each month | Time to clear | Interest paid |
|---|---|---|
| £100 | 3 years 9 months | about £1,440 |
| £150 | 2 years 2 months | about £795 |
| £250 | 1 year 2 months | about £430 |
Going from £100 to £250 a month more than halves the time and cuts the interest by roughly £1,000. It is also why paying only the minimum, which shrinks as your balance does, can stretch a debt out for many years.
What this calculator assumes
- The APR and balance stay the same, and you add no new spending to the card.
- Interest is charged monthly on the outstanding balance, using your card’s APR converted to an effective monthly rate.
- It does not model a 0% deal. A balance transfer pauses interest and changes the picture entirely, so it is worth considering if you can qualify.
Frequently asked questions
How long will it take to pay off my credit card?
It depends on the balance, the APR and how much you pay each month. The calculator simulates it month by month, charging interest on the remaining balance, and shows how many months it takes and roughly how much interest you pay in total. Paying a little more each month shortens it sharply.
Why does paying only the minimum take so long?
Minimum payments are usually set as a small percentage of the balance, so as the balance falls the payment falls too, and most of it goes on interest rather than clearing the debt. That can stretch a repayment over many years. Paying a fixed amount each month, rather than the shrinking minimum, clears it far faster.
Should I move my balance to a 0% card?
If you can qualify, a 0% balance transfer card can pause interest entirely for a promotional period, so every pound you pay reduces the debt. Watch for the transfer fee and make sure you can clear it, or move again, before the 0% period ends and the standard rate kicks in.
Does clearing a credit card improve my credit score?
Usually yes. Lowering how much of your available credit you are using, your credit utilisation, is one of the quickest ways to lift your score, and a cleared card shows lenders you can manage credit. Checking your report first lets you see the accounts and utilisation lenders are looking at.
