1. What is the Series EE Savings Bond Calculator?

The Series EE Savings Bond Calculator Inventory helps investors calculate the current value of their Series EE savings bond portfolio. It uses the compound interest formula with semi-annual compounding to determine the total value of multiple bonds.

2. How Does the Calculator Work?

The calculator uses the Series EE savings bond valuation formula:

\[ Total\ V = \sum V_i \quad where \quad V_i = P_i \times (1 + \frac{rate_i}{2})^{2 \times y_i} \]

Where:

\( Total\ V \) — Total portfolio value (USD)
\( V_i \) — Value of bond i (USD)
\( P_i \) — Purchase amount of bond i (USD)
\( rate_i \) — Annual interest rate of bond i (decimal)
\( y_i \) — Years held for bond i (years)

Explanation: The formula calculates compound interest with semi-annual compounding (interest applied twice per year) for each bond, then sums all bond values for the total portfolio value.

3. Importance of Bond Portfolio Valuation

Details: Regular valuation of Series EE bonds helps investors track portfolio growth, make informed investment decisions, and plan for future financial goals. It provides clarity on the actual current worth of savings bond investments.

4. Using the Calculator

Tips: Enter purchase amount in USD, annual rate as a decimal (e.g., 0.05 for 5%), and years held for each bond. You can add multiple bonds to calculate your complete portfolio value. All values must be positive numbers.
