The Treasury Direct website offers a savings bond calculator to determine the value at a particular date. Other financial institutions, such as FirstState Bank and Valley Bank and Trust, redirect visitors to the Treasury Direct savings bond calculator, notes the official website of each organization.
The Treasury Direct Savings Bond Calculator requires a user to enter a specific date, series bond type, denomination, bond serial number and issue date. From there, a user can calculate the savings bond value. Users can utilize other calculator features to determine a bond's current value, build an inventory of bonds, and find out the value of bonds in past or future months, reports Treasury Direct.
