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 is fundamental to bond valuation and fixed income analysis.

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 (coupon payments and face value) back to present value using the required yield 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 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 and valid.

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 payment frequency affect bond price?
A: More frequent payments generally increase bond price slightly due to faster receipt of cash flows and compounding effects.

Q4: What is the difference between yield and coupon rate?
A: Coupon rate is fixed and determines periodic payments, while yield reflects current market return expectations and changes with market conditions.

Q5: Can this calculator handle zero-coupon bonds?
A: Yes, set coupon rate to 0. The price will be the discounted present value of the face value only.
