Estimate how long it takes to clear a credit card balance with fixed monthly payments and APR. Use it when deciding whether to keep paying the card, move the balance or prioritise a higher-cost debt first.
A £4,200 card balance at 24.9% APR with a £200 monthly repayment will take significantly longer to clear than the headline balance suggests because interest keeps accruing while the debt remains outstanding.
- APR, minimum-payment rules and promotional periods change the payoff path.
- Balance-transfer fees and missed payments can materially alter the result.
- If your payment is too low, the balance may fall very slowly or not at all.

What is this calculator?
Credit Card Repayment Calculator turns the inputs on this page into a transparent planning estimate for the selected jurisdiction.
How is it calculated?

WHY RESULTS DIFFER
Why two users can see different results
Why the result can differ
Different tax codes, payroll periods, Scottish bands, pension methods or lender assumptions can change the outcome.
One-off bonuses, pay frequency, overpayments, allowances and reliefs can move the result away from a simple annual estimate.
Where a rule depends on eligibility or legal status, this page shows an estimate and links to official guidance.
The explanation stays close to the result so users can compare the assumptions immediately instead of hunting through a separate policy page.
COMMON QUESTIONS
Frequently asked questions
Is this a balance-transfer calculator?
No. It is a fixed-payment repayment estimate, not a card-transfer comparison.
What if my card has a promotional rate?
The payoff time will change once the promotion ends or if the APR differs from the model.
Should I pay this or an overdraft first?
Usually the higher-cost debt first, but compare the actual rates and fees before deciding.
