See how long it takes to clear your balance and how extra payments reduce interest.
This credit card payoff calculator estimates how long it may take to clear your balance based on your APR, minimum payment, and any extra monthly amount you choose to add. It shows how interest builds over time, how long repayment could take, and how much faster you can become debt-free by paying more than the minimum. That makes it useful when you want to compare payoff options before choosing a realistic monthly target.
Why this matters: credit card debt is expensive because interest can keep compounding while the balance remains high. A low payment may feel manageable, but it can stretch repayment over many months or years and increase the total interest cost. This calculator helps you see that trade-off clearly so you can decide whether a higher payment, balance transfer, or broader debt plan may save money.
Practical ways to use the calculator: test your current minimum payment first, then add a small extra amount such as £25, £50, or £100 to see the impact on payoff time and total interest. If you have several cards, many people either focus on the highest APR first to reduce interest or the smallest balance first for momentum. This page helps you judge how much difference one extra payment can make before you commit.
Important limitations: results are estimates based on a constant APR and steady monthly payments. Real credit card balances can change because of new spending, fees, promotional rates, penalty rates, or daily interest calculations that differ by lender. For the most reliable plan, stop adding new purchases to the card while paying it down and rerun the calculator whenever your rate or payment changes.
Shows the first 24 months for readability. If payoff takes longer, the calculation still uses the full schedule.

We apply your APR as a monthly rate, add interest each month, then subtract your payment (minimum + extra). The schedule is simulated until the balance reaches £0. Results are estimates and may differ from your lender’s calculations.
A good credit card payoff calculator is most useful when you compare more than one repayment scenario. Start with your current minimum payment, then test a slightly higher monthly amount to see whether the extra cash meaningfully reduces your payoff time and total interest. This helps you set a target that is aggressive enough to save money but still realistic for your wider budget.
It also helps to think beyond one month. Paying extra once is helpful, but paying the same additional amount every month often creates the biggest long-term effect because it reduces the balance earlier. A lower balance means less interest is charged in later months, which is why even modest overpayments can have a stronger impact than many people expect.
If you are deciding between several debt strategies, look at three numbers together: the monthly payment, total interest, and total months to payoff. Seeing all three at once makes it easier to decide whether your best next step is to increase payments, reduce spending, or combine this with a broader debt snowball or avalanche plan.
This calculator uses standard financial formulas and simplified assumptions (for example: constant rates, regular payments, and rounding). Real-world results can differ due to fees, taxes, rate changes, compounding conventions, and account rules.

It estimates how long it may take to clear a balance based on your APR and monthly payment, and shows how much interest you could pay over time.
Paying more than the minimum usually reduces total interest and shortens payoff time significantly because less interest accrues on the remaining balance.
APR is an annual rate, but credit card interest is typically calculated daily and charged monthly. This calculator uses a standard monthly approximation.
Many people use the avalanche method (highest APR first) to minimize interest, or the snowball method (smallest balance first) for motivation.
This tool focuses on interest based on APR. Late fees, balance transfer fees, and new purchases can change the outcome.
