How much are my Savings Bonds worth?

I have many Series EE bonds I'd like to cash in, but I would like to know the dollar amount I'd be receiving before I take them to the bank. Is there a web site that would allow me to do this myself?

You can use our Savings Bond Calculator to find out the current value of your Savings Bonds. Our calculator shows redemption values, which means if you have any Savings Bonds less than five years old, the early-redemption penalty has already been deducted from the value we give you.
