I'd like to see this, too... Is there even an API call to trigger input formula calculation?
I think a simple dispatch can help you here.Are you filling these values at a leter state in a Workflow?
I tried some different things in dispatch without success. If I could do multiplication in dispatch then I could make it happen, but for some reason dispatch is capable of addition and subtraction but not multiplication or division. We're not really using workflows at this point so I need it to happen at check-in. If there something I should try let me know.
