Fiscal Service Announces New Savings Bonds Rates, Series I to Earn 4.28%, Series EE to Earn 2.70%


May 1, 2024

Series EE savings bonds issued May 2024 through October 2024 will earn an annual fixed rate of 2.70% and Series I savings bonds will earn a composite rate of 4.28%, a portion of which is indexed to inflation every six months. The EE bond fixed rate applies to a bond’s 20-year original maturity. Bonds of both series have an interest-bearing life of 30 years.

Rates for savings bonds are set each May 1 and November 1. Interest accrues monthly and compounds semiannually. Bonds held less than five years are subject to a three-month interest penalty.

I Bond Composite Rate of 4.28% includes a Fixed Rate of 1.30%

The composite rate for Series I Savings Bonds is a combination of a fixed rate, which applies for the 30-year life of the bond, and the semiannual inflation rate. The 4.28% composite rate for I bonds issued from May 2024 through October 2024 applies for the first six months after the issue date. The composite rate combines a 1.30% fixed rate of return with the 2.96% annualized rate of inflation as measured by the Consumer Price Index for all Urban Consumers (CPI-U). The CPI-U increased from 307.789 in September 2023 to 312.332 in March 2024, a six-month change of 1.48%.

Series EE Bonds Issued May 2005 and Later

Series EE bonds issued from May 2024 through October 2024 earn today’s announced rate of 2.70%. All Series EE bonds issued since May 2005 earn a fixed rate in the first 20 years after issue. At 20 years, the bonds will be worth at least two times their purchase price. The bonds will continue to earn interest at their original fixed rate for an additional 10 years unless new terms and conditions are announced before the final 10-year period begins.

Series EE Bonds Issued from May 1997 through April 2005

Series EE bonds issued from May 1997 through April 2005 continue to earn market-based interest rates set at 90% of the average 5-year Treasury securities yields for the preceding six months. The new interest rate for these bonds, effective as the bonds enter semiannual interest periods from May 2024 through October 2024 is 3.81%. Market-based rates are updated each May 1 and November 1.

Series EE Bonds Issued Before May 1997

Series EE bonds issued before May 1997 earn various rates for semiannual earnings periods, depending on the issue dates. Please visit for details and current values.

Savings Bonds Over 30 Years Have Stopped Earning Interest

All Series E savings bonds have matured and stopped earning interest. Series EE bonds issued from January 1980 through May 1994 are no longer earning interest. Series EE bonds issued from June 1994 through October 1994 will stop earning interest during the next six months.
