Calculate Your Bowling Handicap
Calculate your USBC bowling handicap from your average score. Used for league play to level the playing field.
How Bowling Handicap Works
Handicap = (Basis Score - Your Average) × Handicap Percentage. With a 220 basis and 90% factor: a bowler averaging 155 gets (220-155) × 0.90 = 58.5 → 58 pins per game handicap (always rounded down). This is added to each game score to create a level playing field. A 155-average bowler gets 58 pins per game; a 200-average bowler gets 18. Bowlers above the basis score get zero handicap.
League Settings
Common settings: Basis score: 210-230 (most leagues use 220). Percentage: 80-100% (most use 90%). Higher percentage = more equalization between skill levels. 100% handicap theoretically equalizes everyone to the basis score. 80% still gives better bowlers an edge. Your league secretary sets these parameters — check your league rules sheet for your specific numbers.
