How much is a 100 savings bond worth?

The value of a $100 savings bond depends on its issue date and the interest it has accrued over time. Generally, U.S. savings bonds earn interest for 30 years, and their value increases as they accumulate interest. To determine the current worth of a specific bond, you can use the U.S. Department of the Treasury's online savings bond calculator, which accounts for the bond's issue date and current interest rates.
