Redeemed a series EE savings bond, is the interest the redeemed amount less face?

[cbusa]

I redeemed a series ee paper savings bond. The amount on the bond was $100 but I got about $140 when I redeemed. The bank didn't give me anything in terms of breakdown on interest. Is the interest $40, $140-$100 face value paid?

No.  Not the Redeemed amount - Face value.  You probably paid less than the face value when you bought it.  Like only 50%.  You have to find what you bought it for.  Anything over your cost is the interest.
