1. What is Bond Price Calculation?

Bond price calculation determines the present value of a bond's future cash flows, including periodic coupon payments and the final face value repayment. It helps investors assess whether a bond is fairly priced 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) to their present value using the required yield as the discount rate.

3. Importance of Bond Pricing

Details: Accurate bond pricing is essential for investment decisions, portfolio management, risk assessment, and determining fair market value in bond trading.

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 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: Why does bond price change over time?
A: Bond prices change due to interest rate movements, credit rating changes, time to maturity, and market demand/supply dynamics.

Q3: What is the difference between coupon rate and yield?
A: Coupon rate is fixed and represents the annual interest payment as a percentage of face value. Yield is the actual return investors receive based on the current market price.

Q4: When is a bond priced at par, premium, or discount?
A: Par: coupon rate = yield; Premium: coupon rate > yield; Discount: coupon rate < yield.

Q5: 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 and compounding effects.
