How to Use the Credit Card Payoff Calculator
- Enter your current balance — type the total outstanding balance on your credit card.
- Enter the APR — find your card's APR on your statement or in your online banking. This is the annual interest rate charged on your balance.
- Set your monthly payment — enter the fixed amount you plan to pay each month. This must be more than the monthly interest charge for the balance to decrease.
- Click "Calculate" — the calculator shows how many months until payoff, total interest, and total amount paid.
- See the extra payment comparison — the calculator automatically shows how much you would save by paying an extra £50 per month.
How Credit Card Interest Works
Credit card interest is calculated on the outstanding balance each month. The monthly rate is the APR divided by 12. Each month, interest is added to the balance, and your payment is then subtracted. If your payment is larger than the interest charge, the excess reduces the principal balance. If your payment only just covers the interest, the balance barely decreases and it can take decades to pay off the card. This calculator simulates the month-by-month payoff process, adding interest and subtracting your payment each month until the balance reaches zero. It also calculates what happens if you increase your payment by £50 per month, showing the time saved and interest saved. Even small increases in monthly payment can have a dramatic effect on both the payoff time and total interest. For example, on a £3,000 balance at 19.9% APR, increasing your payment from £100 to £150 per month could save hundreds of pounds in interest and cut years off the repayment time.
How is credit card interest calculated?
Credit card interest is typically calculated on the outstanding balance each month. The monthly rate is the APR divided by 12. Each month, this rate is applied to your remaining balance to determine the interest charge. If you pay your full balance each month by the due date, no interest is charged during the grace period.
What is the minimum payment on a credit card?
The minimum payment is the smallest amount you must pay each month to keep your account in good standing. In the UK, it is typically the greater of a fixed amount (often £5 or £25) or a percentage of the balance (usually 1-3% plus that month's interest). Paying only the minimum can mean it takes many years to clear the balance.
How can I pay off my credit card faster?
Pay more than the minimum each month, as even small extra amounts make a significant difference. Consider transferring the balance to a 0% balance transfer card to stop interest accruing. Use either the avalanche method (pay the highest APR card first) or the snowball method (pay the smallest balance first). Setting up a direct debit for a fixed amount above the minimum is an effective strategy.
What is a balance transfer?
A balance transfer moves your existing credit card debt to a new card with a 0% introductory interest rate, typically lasting 12 to 24 months. This lets you pay down the principal without accruing interest. Most balance transfer cards charge a one-off fee of 1-3% of the transferred amount, which is usually much less than the interest you would otherwise pay.
Does paying off a credit card improve my credit score?
Yes, reducing your credit card balance improves your credit utilisation ratio, which is one of the most important factors in your credit score. Keeping utilisation below 30% of your total credit limit is generally recommended. Paying on time every month also builds a positive payment history, further strengthening your score.
What happens if I only pay the minimum?
Paying only the minimum means most of your payment covers interest rather than reducing the actual balance. A £3,000 balance at 20% APR with minimum payments could take over 25 years to clear and cost thousands of pounds in interest. Paying even a modest fixed amount above the minimum dramatically reduces both the repayment time and total interest cost.
