1. What is the Monthly Interest Calculation?

The monthly interest calculation for low-interest credit cards in the UK determines how much interest you'll pay each month on your outstanding balance. It's based on your principal balance and the card's annual percentage rate (APR).

2. How Does the Calculator Work?

The calculator uses the simple interest formula:

Where:

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

Explanation: The annual rate is divided by 12 to get the monthly rate, then multiplied by the principal balance to calculate the interest.

3. Importance of Interest Calculation

Details: Understanding monthly interest helps with budgeting and shows the true cost of carrying a balance. Even low APR cards can accumulate significant interest over time.

4. Using the Calculator

Tips: Enter your current credit card balance in GBP and the card's APR percentage. The calculator will show your estimated monthly interest charge.
