EE U.S. Savings Bonds reach maturity based on the date they were issued. The month and year of issue are listed on the front of the bond. If you purchased the bond through a Treasury Direct account, the issue date will be listed in your online account. All EE bonds reach final maturity and stop earning interest 30 years after they were issued.
Bonds Purchased Since May 2005
The U.S. Treasury guarantees EE bonds issued after May 2005 will double in value after 20 years. That is considered the date of "original maturity."
Previous Purchase Date Ranges
Most EE bonds purchased between May 1997 and April 2005 will have doubled in value after 17 or 20 years. Bonds issued from May 1995 to May 2003 will reach original maturity in 17 years. Bonds issued after that reach original maturity in 20 years.
May 1995 to April 1997
While the interest rates on bonds purchased between May 1995 and April 1997 vary, they reach original maturity—doubling in purchase value—17 years from the date they were issued.
Purchases Prior to May 1995
The time after which bonds purchased prior to May 1995 reach the original maturity date ranges from eight to 18 years. A number of different interest rate calculations were made for these bonds over several years, resulting in varied maturity dates. A full table may be found on the Treasury Direct website.
