Most often leagues end up with a "share the wealth" type prize fund. If people are paying in, they want something back no matter if they "earn" it or not. Most of the time a dollar value is placed on points. Like in one of our scratch leagues, 1 point is worth $1.50 to the team (50 cents per person), there are 30 points available each night per pair, so $45 a night is up for grabs per pair. Then at the end of the year, you get paid out based on total points. You also have to establish what other things you want to pay out for, like team hi 30, hi 10, individual, top scores, averages, most improved averages, etc, and how much you want to give for all of that.
