Interest calculator

Want to know how much interest you'll earn each year? Select a Savings Bond, enter your desired investment amount and hit VIEW! Move your cursor over the charts to find out when each interest payment will occur.

Thinking of redeeming your Savings Bond before it matures? Click on the "If you redeem early" tab, choose the month and year of redemption and hit SUBMIT. See how your return changes with your investment period!

Figures displayed are estimates only. For simplicity, the calculator assumes that the Savings Bonds are issued and pay interest on the 1st calendar day of the month, which may not always be the case. As a result, the actual interest you receive may vary slightly. For more information, please refer to the technical specifications for Savings Bonds.
