1. What is the US Savings Bond Redemption Calculator?

The US Savings Bond Redemption Calculator estimates the current value of a savings bond based on the purchase amount, annual interest rate, years held, and any applicable early redemption penalties. It helps bond holders understand their investment's current worth.

2. How Does the Calculator Work?

The calculator uses the redemption formula:

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

Where:

\( P \) — Purchase amount (USD)
\( rate \) — Annual interest rate (decimal)
\( y \) — Years held (years)
\( Penalty \) — Early redemption penalty (decimal)

Explanation: The formula calculates compound interest with semi-annual compounding and applies an early redemption penalty if applicable.

3. Importance of Redemption Value Calculation

Details: Knowing the current redemption value helps investors make informed decisions about holding or cashing in their bonds, especially when considering early redemption penalties and alternative investment opportunities.

4. Using the Calculator

Tips: Enter the original purchase amount in USD, annual interest rate as a decimal (e.g., 0.05 for 5%), years held, and any early redemption penalty as a decimal. All values must be valid positive numbers.
