Series I Bonds and Series EE Bonds are two types of U.S. savings bonds issued by the Treasury Department. These bonds are designed to offer a secure and low-risk investment option to individuals. Understanding their differences is crucial for making informed investment decisions.
What Are Series I Bonds?
Definition and Features
Series I Bonds are a type of savings bond designed to protect investors from inflation. The interest rate on Series I Bonds is a combination of a fixed rate and an inflation rate, which is adjusted semi-annually based on the Consumer Price Index for All Urban Consumers (CPI-U).
- Interest Rate Components: The total interest rate is composed of a fixed rate, which remains constant for the life of the bond, and an inflation rate that adjusts every six months, reflecting changes in inflation.
- Purchase Limits: As of 2023, individuals can purchase up to $10,000 in electronic I Bonds each year through TreasuryDirect, plus an additional $5,000 in paper bonds using their federal tax refund.
- Tax Benefits: Interest earned on Series I Bonds is exempt from state and local taxes and can be deferred until the bond is redeemed or matures.
Calculation Example
For Series I Bonds, the interest rate is calculated using the formula:
If the current fixed rate is 0.20% and the semi-annual inflation rate is 1.50%, the composite rate would be calculated as:
What Are Series EE Bonds?
Definition and Features
Series EE Bonds offer a fixed interest rate and are guaranteed to at least double in value if held for 20 years, irrespective of the initial interest rate. The interest rate is set at the time of purchase and remains fixed for the life of the bond.
- Fixed Interest Rate: The interest rate is set when the bond is issued and remains constant throughout the bond’s term.
- Guaranteed Doubling: If the bond’s accumulated value does not double within 20 years, the Treasury will make a one-time adjustment to ensure the bond’s value doubles.
- Purchase Limits: Similar to I Bonds, individuals can purchase up to $10,000 in electronic EE Bonds annually through TreasuryDirect.
- Tax Benefits: Interest earned on Series EE Bonds is also exempt from state and local taxes and can be deferred.
