1. What is the U.S. Treasury Bond Value Formula?

The U.S. Treasury Bond Value formula calculates the present value of a bond by summing the present values of all future coupon payments and the face value payment at maturity. This formula is fundamental to bond pricing 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 (USD)
\( C \) — Periodic coupon payment = (coupon rate × F) ÷ m (USD)
\( r \) — Periodic yield to maturity = yield ÷ m (decimal)
\( t \) — Period number (unitless)
\( F \) — Face value (USD)
\( n \) — 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) to their present value using the yield to maturity as the discount rate.

3. Importance of Bond Valuation

Details: Accurate bond valuation is crucial for investors, portfolio managers, and financial analysts to determine fair bond prices, assess investment opportunities, and manage fixed-income portfolios effectively.

4. Using the Calculator

Tips: Enter face value in USD, 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 difference between coupon rate and yield?
A: Coupon rate is the fixed interest rate paid on the bond's face value, while yield to maturity is the total return anticipated if the bond is held until maturity.

Q2: Why does bond price change when yield changes?
A: Bond price and yield have an inverse relationship. When market interest rates rise, existing bond prices fall to make their yields competitive with new bonds.

Q3: What are U.S. Treasury bonds?
A: U.S. Treasury bonds are long-term debt securities issued by the U.S. government with maturities of 20-30 years, considered among the safest investments.

Q4: How does payment frequency affect bond price?
A: More frequent payments generally increase the bond's present value due to earlier receipt of cash flows, though the effect is typically small.

Q5: What happens if yield equals coupon rate?
A: When yield to maturity equals the coupon rate, the bond typically trades at par value (face value).
