1. What is the United States Savings Bond Calculator?

The United States Savings Bond Calculator estimates the future value of savings bonds based on the issue price, annual interest rate, and time since issuance. It helps investors understand the growth potential of their bond investments over time.

2. How Does the Calculator Work?

The calculator uses the savings bond formula:

\[ FV = P \times (1 + \frac{r}{2})^{2 \times t} \]

Where:

$ FV $ — Future Value (bond value in USD)
$ P $ — Issue Price (initial investment in USD)
$ r $ — Annual Interest Rate (decimal form)
$ t $ — Time Since Issue (in years)
