1. What is the Series EE Bond Calculator?

The Series EE Bond Calculator calculates the current value of US Series EE savings bonds with semi-annual compounding. It helps investors determine the worth of their bonds based on purchase amount, annual interest rate, and holding period.

2. How Does the Calculator Work?

The calculator uses the Series EE bond formula:

Where:

• \( V \) — Current value (USD)
• \( P \) — Purchase amount (USD)
• \( rate \) — Annual interest rate (decimal)
• \( y \) — Years held (years)

Explanation: The formula accounts for semi-annual compounding, where interest is calculated twice per year and added to the principal.

3. Importance of Bond Valuation

Details: Accurate bond valuation is crucial for financial planning, investment tracking, and understanding the growth of savings over time. Series EE bonds are guaranteed to double in value after 20 years.

4. Using the Calculator

Tips: Enter purchase amount in USD, annual interest rate as a decimal (e.g., 0.025 for 2.5%), and years held. All values must be valid (purchase amount > 0, rate ≥ 0, years ≥ 0).
