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 face value at maturity. It determines the fair market price of a bond based on its characteristics and current market conditions.

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 all future cash flows (coupon payments and principal repayment) to their present value using the required yield as the discount rate.

3. Importance of Bond Price Calculation

Details: Bond pricing is essential for investors to determine fair value, for issuers to price new bonds appropriately, and for portfolio managers to assess investment opportunities and risks.

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 the 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 yields rise, bond prices fall, and vice versa.

Q2: Why do bonds sell at premium or discount?
A: Bonds sell at premium when coupon rate > market yield, and at discount when coupon rate < market yield. They sell at par when rates are equal.

Q3: How does time to maturity affect bond price?
A: Longer-term bonds are more sensitive to interest rate changes. Their prices fluctuate more for a given change in yield.

Q4: What are zero-coupon bonds?
A: Zero-coupon bonds pay no periodic coupons. Their price is simply the present value of the face value: P = F ÷ (1 + r)^n.

Q5: How accurate is this calculator for real-world bonds?
A: This provides a good estimate for standard bonds. For more complex bonds with embedded options or unusual features, specialized models are needed.
