Is there a Plywood calculator avail to help figure cut lists?

is there something avail for plywood, similar to this that Rockler sells for cabinet doors?

There are several nice cut list programs available. I personally use CutList Plus. Historically, I was using the "Silver" version but recently upgraded to "Gold" to get the proposal features now that I'm doing more commission work. Another one I'm aware of is MaxCut.

Cut list really helped when I built my kitchen cabinets. It even has a label printing function to keep track of the pieces after they are cut.

Thanks guys! Playing with it now...
