How It Works

How Bowling Handicap Is Calculated

Formula

Handicap = (Basis Score - Your Average) x Handicap Percentage

Common League Settings

  • Basis Score: Usually 200, 210, or 220. This is the theoretical "perfect" average for the league.
  • Handicap Percentage: Usually 80-100%, with 90% being the most common. A higher percentage gives lower-average bowlers more pins.

    • Purpose

    Handicap levels the playing field so bowlers of different skill levels can compete fairly in leagues and tournaments.

    Worked Example

    Calculate handicap for a bowler with a 165 average, basis 220, 90% handicap.

    bowler_avg = 165basis_score = 220handicap_pct = 90
    1. 01Gap from basis = 220 - 165 = 55 pins.
    2. 02Handicap = 55 x 90% = 55 x 0.9 = 49.5, rounded to 50 pins.
    3. 03If the bowler bowls their average (165), the handicap score = 165 + 50 = 215.
