1. What is the Tesco Credit Card Interest Calculation?

The Tesco Credit Card interest calculation determines how much interest you'll pay over a 30-day period based on your current balance and annual interest rate. This helps cardholders understand their potential interest charges.

The calculator uses the formula:

Where:

• \( P \) — Principal balance (GBP)
• \( R \) — Annual interest rate (as a decimal)
• \( I \) — Interest for 30 days (GBP)
