This savings bond calculator will help you determine the value of your bonds and understand how much interest you have earned.

## Savings Bond Calculator

### How to Use the Calculator

Enter the purchase price of the savings bond, the annual interest rate, and the number of years until the bond matures. Then click on “Calculate” to see the maturity value of your savings bond.

### How It Calculates the Result

The calculator uses the formula for compound interest to determine the future value of a savings bond: `FV = P(1 + r)^t`

, where:

`FV`

is the future value at maturity,`P`

is the purchase price,`r`

is the annual interest rate (as a decimal),`t`

is the number of years until maturity.

### Limitations

The calculator assumes a fixed annual interest rate and does not account for taxes, inflation, or any potential penalties for early redemption of the bond. It should be used as a guideline and not relied upon for exact investment outcomes.
