Use the Savings Bond Calculator on the TreasuryDirect website to calculate the cash value of EE savings bonds, advises Investopedia. Alternatively, download the Savings Bond Wizard from the TreasuryDirect website to find the value of EE savings bonds, states Bankrate.
To use the Savings Bond Calculator, enter the series, denomination and issue date of each bond, and click the Calculate button, instructs TreasuryDirect. Repeat this process for each bond. After entering all the bonds, the website provides options for saving and printing an inventory of the bonds, making it easy to retrieve and update the document in the future. Using the Savings Bond Wizard is a similar process that involves downloading the wizard and entering the information for each bond.
