1. What is the Treasury Bond Price Formula?

The Treasury Bond Price Formula calculates the present value of a bond by summing the discounted future cash flows (coupon payments and face value). It's essential for bond valuation and investment analysis.

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.

3. Importance of Bond Price Calculation

Details: Accurate bond pricing is crucial for investment decisions, portfolio management, risk assessment, and understanding 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., 0.05 for 5%), 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 payment divided by current price, while YTM considers all future cash flows and price appreciation/depreciation.
