For me it depends on a number of things. I would say on average ~60%, sometimes more. However, if we are going out to eat a lot or if my wife decides to buy chicken or fish which she does from time to time them the percentage goes down. We usually have a freezer full of elk though and it all gets eaten. So I guess an overall percentage is hard to figure, but my family (me, wife, 2 small kids) eat 160-200 lbs of elk/deer a year. Plus the occaisional squirrels, rabbits, fish.
