1. What is the US Treasury Direct Savings Bond Calculator?

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

2. How Does the Calculator Work?

The calculator uses the savings bond 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 (years)

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

3. Importance of Bond Value Calculation

Details: Accurate bond value calculation is crucial for investment planning, retirement savings, and understanding the return on government bond investments.

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 since issue in years. All values must be valid positive numbers.
