1. What is Bond Valuation?

Bond valuation is the process of determining the fair value of a bond. It involves calculating the present value of all expected future cash flows from the bond, including periodic coupon payments and the final face value payment at maturity.

2. How Does the Calculator Work?

The calculator uses the bond valuation 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 back to their present value using the required yield to maturity as the discount rate.

3. Importance of Bond Valuation

Details: Bond valuation is essential for investors to determine whether a bond is fairly priced, overpriced, or underpriced in the market. It helps in making informed investment decisions and portfolio management.

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 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 valuation?
A: More frequent payments generally increase the bond's value slightly due to earlier receipt of cash flows.

Q4: What is the difference between current yield and yield to maturity?
A: Current yield is annual coupon payment divided by current price, while YTM considers all future cash flows and time value of money.

Q5: When is a bond considered to be trading at a premium or discount?
A: A bond trades at a premium when price > face value (coupon rate > yield), and at a discount when price < face value (coupon rate < yield).
