1. What is the US Treasury Bonds Calculator?

The US Treasury Bonds Calculator estimates the future value of savings bonds using the semi-annual compounding formula. It helps investors understand how their bond investments will grow over time based on the issue price, interest rate, and time held.

2. How Does the Calculator Work?

The calculator uses the US Treasury Bonds formula:

Where:

• \( FV \) — Future value of the bond (USD)
• \( P \) — Issue price of the bond (USD)
• \( r \) — Annual interest rate (decimal)
• \( t \) — Time since issue in years

Explanation: The formula calculates compound interest with semi-annual compounding, which is standard for US Treasury savings bonds.

3. Importance of Bond Value Calculation

Details: Calculating the future value of bonds is essential for financial planning, investment strategy, and understanding the growth potential of fixed-income securities.

4. Using the Calculator

Tips: Enter the bond's issue price in USD, annual interest rate as a decimal (e.g., 0.05 for 5%), and time since issue in years. All values must be valid (price > 0, rate ≥ 0, time ≥ 0).
