1. What is Zero Coupon Bond Interest Rate?

The zero coupon bond interest rate is the implied rate of return on a bond that pays no periodic interest but is sold at a discount to its face value. The investor's return comes from the difference between the purchase price and the face value at maturity.

2. How Does the Calculator Work?

The calculator uses the zero coupon bond formula:

Where:

• \( FV \) — Face value of the bond ($)
• \( PV \) — Present value or purchase price ($)
• \( n \) — Time to maturity in years
• \( r \) — Annual interest rate (as decimal)

Explanation: The formula calculates the compound annual growth rate that equates the present value to the face value over the bond's term.

3. Importance of Interest Rate Calculation

Details: Calculating the implied interest rate helps investors compare zero coupon bonds with other investment options and assess their true yield.

4. Using the Calculator

Tips: Enter the bond's face value, current purchase price, and time to maturity in years. All values must be positive numbers.
