1. What is the US Treasury Savings Bond Calculator?

The US Treasury Savings Bond Calculator estimates the future value of savings bonds with semi-annual compounding. It helps investors understand the growth of their bond investments over time based on the issue price, annual interest rate, and time held.

2. How Does the Calculator Work?

The calculator uses the US Treasury bond formula:

Where:

• \( FV \) — Future value of the bond (USD)
• \( P \) — Issue price or principal amount (USD)
• \( r \) — Annual interest rate (expressed as 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. The interest is compounded twice per year.

3. Importance of Bond Value Calculation

Details: Accurate bond valuation is crucial for financial planning, investment decision-making, and understanding the real return on government bond investments over time.

4. Using the Calculator

Tips: Enter the original issue price in USD, annual interest rate as a decimal (e.g., 0.05 for 5%), and time held in years. All values must be positive numbers.
