1. What is the Series EE Savings Bond Formula?

The Series EE savings bond formula calculates the current value of a savings bond based on the purchase amount, annual interest rate, and number of years held. It accounts for semi-annual compounding of interest.

2. How Does the Calculator Work?

The calculator uses the Series EE savings bond formula:

Where:

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

Explanation: The formula calculates compound interest with semi-annual compounding, where the interest is applied twice per year.

3. Importance of Savings Bond Valuation

Details: Accurate valuation of Series EE savings bonds is essential for financial planning, tax reporting, and understanding investment growth over time.

4. Using the Calculator

Tips: Enter purchase amount in USD, annual interest rate as a decimal (e.g., 0.05 for 5%), and years held. All values must be valid (purchase amount > 0, rate ≥ 0, years ≥ 0).
