1. What is the Premium Bond Interest Calculator?

The Premium Bond Interest Calculator calculates the effective interest rate equivalent for premium bonds based on the annual prize fund rate. It helps investors understand the equivalent interest return they can expect from premium bond investments.

2. How Does the Calculator Work?

The calculator uses the effective rate formula:

Where:

• \( \text{Prize Fund Rate} \) — Annual prize fund rate (percentage)
• \( \text{Effective Rate} \) — Equivalent effective interest rate (percentage)

Explanation: The effective rate represents the equivalent interest rate that would provide the same return as the premium bond's prize fund rate.

3. Importance of Effective Rate Calculation

Details: Calculating the effective rate helps investors compare premium bond returns with traditional interest-bearing investments, enabling better investment decision-making and portfolio optimization.

4. Using the Calculator

Tips: Enter the annual prize fund rate as a percentage. The calculator will compute the equivalent effective interest rate for comparison purposes.
