Understanding Series EE Savings Bonds
Series EE Savings Bonds are low-risk savings products issued by the U.S. Treasury. They are unique because they are guaranteed to double in value if held for a specific period (usually 20 years for bonds issued since May 2005). Whether you have old paper certificates or modern electronic bonds, tracking their value is essential for your financial planning.
How the Calculation Works
This calculator estimates the current value of an EE bond based on the following logic:
- Purchase Price: Paper bonds were sold at 50% of their face value (a $100 bond cost $50). Electronic bonds are purchased at face value.
- Interest Accrual: Interest is added to the bond every month and compounds semiannually (twice a year).
- The 20-Year Guarantee: For bonds issued from May 2005 onwards, the Treasury guarantees the bond will be worth double its purchase price after 20 years. If the accrued interest doesn't reach that amount, the Treasury makes a one-time adjustment.
- Maturity: EE bonds earn interest for up to 30 years. After 30 years, they reach final maturity and stop earning interest entirely.
Example: $1,000 Paper EE Bond
If you purchased a paper EE bond with a $1,000 face value in May 2003:
- Your Cost: $500.00
- Interest Type: Variable rate (based on 90% of 5-year Treasury yields).
- Strategy: Because this bond was issued before the fixed-rate era (pre-May 2005), it does not follow the same 20-year doubling rule but may have reached its face value much sooner depending on historical rates.
Important Tax Information
The interest earned on EE bonds is subject to federal income tax but is exempt from state and local income taxes. You can generally defer reporting the interest for federal tax purposes until you cash the bond, it reaches final maturity, or you give it to someone else.
