Understanding UK Credit Card Interest
help How is interest calculated?
In the UK, credit card interest is typically calculated daily based on your outstanding balance and applied once a month to your statement. The **APR (Annual Percentage Rate)** is the annual cost of borrowing, which includes both interest and any standard fees.
When you carry a balance month-to-month, you pay **compound interest**—essentially paying interest on interest previously added to your account.
The Danger of Minimum Payments
Most UK lenders set a minimum payment of around 1% of the balance plus interest. If you only pay this amount, it can take 20+ years to clear even a small debt because almost all the payment goes toward interest, not the principal debt.
