1. What is the Savings Bonds Interest Calculator?

The Savings Bonds Interest Calculator calculates the interest earned and future value of savings bonds using semi-annual compounding. It helps investors understand the growth of their bond investments over time.

The calculator uses the savings bonds interest formula:

Where:

• \( FV \) — Future value (USD)
• \( P \) — Issue price (USD)
• \( r \) — Annual interest rate (decimal)
• \( t \) — Time since issue in years (years)
