A comprehensive guide to Series EE Bonds, including their definition, mechanics, how they work, and maturity details. Learn about their guaranteed returns and unique features.
A Series EE Bond is a non-marketable, interest-bearing savings bond issued by the U.S. Department of the Treasury. These bonds are designed to be a secure investment instrument with a guaranteed minimum return, as they are backed by the full faith and credit of the U.S. government.
Series EE Bonds are purchased at their face value and earn interest over time. Interest accrual follows these general principles:
Interest Rate: Series EE Bonds issued since May 2005 have a fixed interest rate. The rate is determined at the time of purchase and remains constant throughout the life of the bond.
Compounding: Interest is compounded semi-annually, meaning the interest earned in one period will earn additional interest in subsequent periods.
Guarantee: The U.S. government guarantees that the bond will at least double in value if held for 20 years. If the bond does not double, a one-time adjustment is made to ensure this guarantee is met.
Initial Maturity: Series EE Bonds reach their initial maturity at 20 years. At this point, the value of the bond is guaranteed to have doubled.
Final Maturity: The final maturity for Series EE Bonds is 30 years. During this period, the bonds continue to earn interest beyond the initial maturity date up to their final maturity.
