1. What is the Bond Price Formula?

The bond price formula calculates the present value of a bond by summing the present value of all future coupon payments and the face value. It's fundamental in fixed income securities valuation and helps investors determine the fair price of bonds in the market.

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 (coupon payments and face value) back to their present value using the required yield as the discount rate.

3. Importance of Bond Valuation

Details: Accurate bond valuation is essential for investors to make informed investment decisions, for portfolio management, and for determining whether a bond is overpriced or underpriced in the market.

4. Using the Calculator

Tips: Enter face value in currency units, coupon rate and yield as decimals (e.g., 5% = 0.05), years to maturity, and select the 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: What happens when coupon rate equals yield?
A: When coupon rate equals yield to maturity, the bond trades at par value (price equals face value).

Q3: How does payment frequency affect bond price?
A: More frequent payments generally increase the bond's price slightly due to earlier receipt of cash flows.

Q4: What are zero-coupon bonds?
A: Zero-coupon bonds have no periodic coupon payments. Their price is simply the present value of the face value.

Q5: How does time to maturity affect bond price volatility?
A: Longer-term bonds are more sensitive to interest rate changes, making their prices more volatile.
