I don't think you have to quantify anything, it's not a matter of science or math -- it's about how much that money means to you.
Just imagine some rich guy with a checkbook. Imagine what the minimum number he has to write in order to take your three month old baby. It's a realistic situation and the guy with the checkbook isn't going to pay you what you "want" he's going to pay you what you won't say "no" to.
Assume it's a cash only deal, but figure that if it's Google you'd go even lower on cash if it meant you have a sweet job and salary -- that's obvious.
