1. What is the Bond Price Formula?

The bond price formula calculates the present value of all future cash flows from a bond, including periodic coupon payments and the final face value payment. It's fundamental in fixed income analysis and bond valuation.

2. How Does the Calculator Work?

The calculator uses the bond price 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 present value using the yield to maturity as the discount rate.

3. Importance of Bond Price Calculation

Details: Bond price calculation is essential for investors to determine fair value, assess investment opportunities, manage bond portfolios, and make informed buying/selling decisions in fixed income markets.

4. Using the Calculator

Tips: Enter coupon rate and yield as decimals (e.g., 0.05 for 5%). Face value should be in currency units. Select appropriate payment frequency based on the bond's terms.

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 (price equals face value).

Q3: How does time to maturity affect bond price?
A: Longer-term bonds are more sensitive to interest rate changes. Price volatility increases with longer maturities.

Q4: What is duration in bond pricing?
A: Duration measures bond price sensitivity to interest rate changes. It's the weighted average time to receive cash flows.

Q5: How do zero-coupon bonds differ?
A: Zero-coupon bonds have no periodic payments. Their price is simply the present value of the face value: \( P = \frac{F}{(1 + r)^n} \).
