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. This formula 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, meaning interest is applied twice per year.

3. Importance of Savings Bond Calculation

Details: Accurate bond valuation helps investors understand the growth of their savings bonds over time, plan for future financial goals, and make informed investment decisions.

4. Using the Calculator

Tips: Enter the 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, interest rate ≥ 0, years ≥ 0).
