1. What is the United Savings Bond Calculator?

The United Savings Bond Calculator calculates the current value of savings bonds based on the purchase amount, annual interest rate, and years held. It uses semi-annual compounding to determine the bond's worth over time.

2. How Does the Calculator Work?

The calculator uses the savings bond formula:

\[ V = P \times (1 + \frac{rate}{2})^{2 \times y} \]

Where:

\( V \) — Current value (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 savings bond valuation helps investors understand the growth of their investments over time and make informed financial decisions about bond redemption or continued holding.

4. Using the Calculator

Tips: Enter the original purchase amount in USD, annual interest rate as a decimal (e.g., 0.05 for 5%), and the number of years the bond has been held. All values must be positive.
