United States savings bonds are often given as gifts to students by loved ones or awarded by peers and others for academic, civic or other achievements. They are an affordable, relatively low-hassle and low-risk interest-bearing investment. Your savings bond's value will change as it takes time to mature to face value, but you don’t need to calculate its current worth and accrued interest manually. You can look up your savings bond’s value by its serial number on the U.S. Treasury Department’s TreasuryDirect website.

Step 1

Go to the TreasuryDirect “Calculate the Value of Your Paper Savings Bond(s)” web page to access the U.S. Savings Bonds Calculator.

Step 2

Skip over the “Value as of” field that displays the current month and year.

Step 3

Check your savings bond’s type -- EE Bonds, I Bonds, E Bonds or Savings Notes -- at the top right corner of your bond. Select that type on the “Series” drop-down menu.

Step 4

Select the amount of your bond as displayed on its upper left corner -- $10, $25, $50, $75, $100, $200, $500, $1,000, $5,000 or $10,000 -- on the “Denomination” drop-down menu.

Step 5

Locate your bond’s serial number near its bottom right corner. Enter the number in the “Bond Serial Number” field.

Step 6

Find your bond’s issue date at the top right corner and enter it as a two-digit month followed by a four-digit year in the “Issue Date” field. For example, “11/2005."

Step 7

Click the “Calculate” button to see your bond’s current value.
