1. What is the Bond Price Formula?

The bond price formula calculates the present value of all future cash flows from a bond, including coupon payments and the face value at maturity. It's essential for bond valuation and investment analysis in finance.

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 to their present value using the required yield as the discount rate.

3. Importance of Bond Price Calculation

Details: Bond price calculation is crucial for investors to determine fair value, make investment decisions, assess risk, and understand the relationship between bond prices and interest rates.

4. Using the Calculator

Tips: Enter face value in currency units, coupon rate and yield as decimals (e.g., 5% = 0.05), 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 yields rise, bond prices fall, and vice versa.

Q2: How does coupon rate affect bond price?
A: Higher coupon rates generally result in higher bond prices, all else being equal.

Q3: What happens when a bond is priced at par?
A: When bond price equals face value, the yield to maturity equals the coupon rate.

Q4: How does time to maturity affect bond price volatility?
A: Longer-term bonds are more sensitive to interest rate changes and have greater price volatility.

Q5: What is the difference between current yield and yield to maturity?
A: Current yield is annual coupon divided by current price, while YTM considers all future cash flows and price appreciation/depreciation.
