1. What is the Series EE Savings Bond Calculator?

The Series EE Savings Bond Calculator calculates the current value of Series EE savings bonds using the compound interest formula. These bonds are U.S. government savings bonds that earn interest monthly and compound semiannually.

2. How Does the Calculator Work?

The calculator uses the Series EE savings 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 semiannual compounding, where interest is calculated twice per year and added to the principal.

3. Importance of Savings Bond Calculation

Details: Accurate savings bond valuation helps investors track their investment growth, plan for future financial goals, and make informed decisions about bond redemption timing.

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, interest rate ≥ 0, years ≥ 0).
