1. What is Bond Valuation?

Bond valuation is the process of determining the fair price of a bond. The value of a bond equals the present value of its expected future cash flows, which include periodic coupon payments and the face value at maturity.

2. How Does the Calculator Work?

The calculator uses the bond valuation formula:

\[ Value = \sum \left( \frac{C}{(1 + r)^t} \right) + \frac{F}{(1 + r)^n} \]

Where:

\( C \) — Coupon payment (USD)
\( r \) — Discount rate (as decimal)
\( t \) — Period number (1 to n)
\( F \) — Face value of the bond (USD)
\( n \) — Total number of periods

Explanation: The formula discounts each future cash flow back to present value and sums them to determine the bond's theoretical value.

3. Importance of Bond Valuation

Details: Bond valuation helps investors determine whether a bond is overpriced or underpriced in the market, assess investment opportunities, and make informed buying/selling decisions.

4. Using the Calculator

Tips: Enter the bond's coupon payment in USD, the discount rate as a percentage, the number of coupon periods, the face value in USD, and the total number of periods until maturity.

5. Frequently Asked Questions (FAQ)

Q1: What's the difference between coupon rate and discount rate?
A: The coupon rate is fixed and determines the periodic payments, while the discount rate reflects current market interest rates and the bond's risk.

Q2: Why does bond price change when interest rates change?
A: Bond prices and interest rates have an inverse relationship - when rates rise, existing bond prices fall to match the new yield environment.

Q3: What happens when a bond's coupon rate equals the discount rate?
A: The bond will trade at par (face value) because its cash flows are discounted at the same rate as its coupon payments.

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

Q5: What's the difference between clean and dirty bond price?
A: Clean price excludes accrued interest, while dirty price includes it. The calculator provides the dirty price.
