Frequently asked questions

How is a bowling handicap calculated?

The standard formula is (basis − your average) × handicap percentage, rounded down. For example, with a 145 average, a basis of 220 and 90% handicap: (220 − 145) × 0.90 = 67.5, rounded down to 67 pins added to each game. The basis and percentage are set by your league.

Why do bowling leagues use a handicap based on 220 instead of a player's own average?

Using a fixed scratch number like 220 (rather than the highest average in the league) keeps handicaps consistent across different leagues and seasons, so a bowler's handicap means roughly the same thing whether they're in a strong league or a more casual one.
