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 at maturity. It's a fundamental concept in fixed income securities 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 required yield as the discount rate.

3. Importance of Bond Price Calculation

Details: Bond pricing is essential for investors, traders, and portfolio managers to determine fair value, assess investment opportunities, and make informed buying/selling decisions in fixed income markets.

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 payment frequency. All values must be positive.

5. Frequently Asked Questions (FAQ)

Q1: What happens when yield equals coupon rate?
A: When yield equals coupon rate, the bond typically trades at par value (price = face value).

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

Q3: What is the relationship between yield and price?
A: Bond price and yield have an inverse relationship - when yields rise, prices fall, and vice versa.

Q4: Can this calculator handle zero-coupon bonds?
A: Yes, set coupon rate to 0 and the calculator will price the bond based only on discounting the face value.

Q5: What are the limitations of this model?
A: This model assumes constant yield curve, no default risk, and fixed coupon payments. It doesn't account for callable or convertible features.
