1. What is the Bond Price Formula?

The bond price formula calculates the present value of all future cash flows from a bond, including periodic coupon payments and the final face value payment. It's essential for bond valuation and investment analysis.

2. How Does the Calculator Work?

The calculator uses the bond pricing formula:

\[ P = \sum_{t=1}^{n} \frac{C}{(1 + r)^t} + \frac{F}{(1 + r)^n} \]

Where:

\( P \) — Bond price (currency units)
\( C \) — Periodic coupon payment = (coupon rate × F) ÷ m (currency units)
\( r \) — Periodic yield to maturity = yield ÷ m (decimal)
\( t \) — Period number (unitless)
\( F \) — Face value (currency units)
\( n \) — Total number of periods = years × m (unitless)
\( m \) — Payments per year (unitless)

Explanation: The formula discounts all future cash flows to their present value using the required yield as the discount rate.

3. Importance of Bond Pricing

Details: Accurate bond pricing is crucial for investors, portfolio managers, and financial institutions to determine fair value, assess investment opportunities, and manage risk in fixed income portfolios.

4. Using the Calculator

Tips: Enter face value in currency units, coupon rate and yield as decimals (e.g., 0.05 for 5%), years to maturity, and select payment frequency. All values must be positive.

5. Frequently Asked Questions (FAQ)

Q1: What is the relationship between bond price and yield?
A: Bond price and yield have an inverse relationship. When yield increases, bond price decreases, and vice versa.

Q2: How does coupon rate affect bond price?
A: Higher coupon rates generally result in higher bond prices, all else being equal, because they provide higher periodic payments.

Q3: What happens when coupon rate equals yield?
A: When coupon rate equals yield to maturity, the bond trades at par (price equals face value).

Q4: How does time to maturity affect bond price sensitivity?
A: Longer-term bonds are more sensitive to interest rate changes than shorter-term bonds.

Q5: Can this calculator be used for zero-coupon bonds?
A: For zero-coupon bonds, set coupon rate to zero. The formula simplifies to just the present value of the face value.
