Zero Coupon Bond Rate Formula:
| From: | To: |
The zero coupon bond rate is the implied interest rate earned 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.
The calculator uses the zero coupon bond rate formula:
Where:
Explanation: The formula calculates the compound annual growth rate that equates the present value to the face value over the given time period.
Details: Understanding zero coupon bond rates is essential for comparing different fixed-income investments, valuing bonds, and assessing the time value of money in financial decisions.
Tips: Enter the bond's face value (future value), current price (present value), and time to maturity in years. All values must be positive numbers.
Q1: What's the difference between zero coupon and regular bonds?
A: Zero coupon bonds don't make periodic interest payments; they're sold at a discount and pay the full face value at maturity.
Q2: How does compounding affect the rate?
A: The formula assumes annual compounding. For different compounding periods, the effective annual rate would differ.
Q3: Are zero coupon bond rates the same as yield to maturity?
A: For zero coupon bonds, the rate calculated is effectively the yield to maturity since there are no coupon payments.
Q4: Why are zero coupon bonds sensitive to interest rate changes?
A: Their entire return depends on the final payment, making their present values more volatile to rate changes than coupon bonds.
Q5: How are taxes handled for zero coupon bonds?
A: In many jurisdictions, imputed interest is taxable annually as it accrues, even though no cash is received until maturity.
