1. What is the TreasuryDirect Paper Savings Bond Calculator?

The TreasuryDirect Paper Savings Bond Calculator calculates the current value of paper savings bonds using the official TreasuryDirect formula. It helps investors determine the worth of their bonds based on purchase amount, annual interest rate, and holding period.

2. How Does the Calculator Work?

The calculator uses the TreasuryDirect bond formula:

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

Where:

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

Explanation: The formula accounts for semi-annual compounding, where interest is calculated twice per year and added to the principal amount.

3. Importance of Bond Value Calculation

Details: Accurate bond valuation is essential for financial planning, investment tracking, and understanding the growth of savings over time. It helps investors make informed decisions about holding or redeeming bonds.

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 positive numbers.
