1. What is Bond Price Calculation?

Bond price calculation determines the present value of all future cash flows from a bond, including coupon payments and the face value repayment at maturity. 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 each future cash flow back to present value using the required yield rate, summing all present values to get the bond price.

3. Importance of Bond Pricing

Details: Accurate bond pricing is essential for investment decisions, portfolio management, risk assessment, and understanding the relationship between bond prices and interest rates.

4. Using the Calculator

Tips: Enter face value, coupon rate (as decimal), yield to maturity (as decimal), 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 market interest rates rise, bond prices fall, and vice versa.

Q2: How does payment frequency affect bond price?
A: More frequent payments generally increase the bond price slightly due to earlier receipt of cash flows.

Q3: What is the difference between coupon rate and yield?
A: Coupon rate is fixed and based on the bond's face value, while yield reflects current market conditions and the bond's 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: Can this calculator handle zero-coupon bonds?
A: Yes, set coupon rate to 0. The price will equal the present value of the face value only.
