1. What is the UK Credit Card APR Calculator?

This calculator determines the monthly interest charged on UK credit card balances based on the Annual Percentage Rate (APR). It helps consumers understand how much interest they'll pay each month on their outstanding balance.

2. How Does the Calculator Work?

The calculator uses the standard UK credit card interest formula:

Where:

• \( P \) — Principal balance (GBP)
• \( R \) — Monthly interest rate (UK APR / 12, as decimal)
• \( I \) — Monthly interest charge (GBP)

Explanation: The calculator converts the annual APR to a monthly rate by dividing by 12, then multiplies this by your outstanding balance to determine the monthly interest charge.

3. Importance of APR Calculation

Details: Understanding your monthly interest charges helps with budgeting and demonstrates the true cost of carrying a credit card balance. UK regulations require clear APR disclosure to help consumers compare products.

4. Using the Calculator

Tips: Enter your current credit card balance in GBP and the card's APR (typically between 18.9% and 24.9% for UK cards). The calculator will show your estimated monthly interest charge.
