What is a Bowling Handicap?

A bowling handicap is a scoring adjustment that levels the playing field between bowlers of different skill levels. It allows beginners and experienced bowlers to compete fairly in the same league or tournament.

The handicap system adds bonus pins to lower-average bowlers' scores, giving everyone an equal chance to win. This makes bowling leagues more inclusive and competitive for all participants.

How to Calculate Bowling Handicap

The bowling handicap formula is straightforward:

Handicap = (Basis Score − Your Average) × Percentage Factor

Example Calculation:

Basis Score: 220 (set by your league)

Your Average: 156

Percentage: 90%

Handicap: (220 − 156) × 0.90 = 57.6 → 57 pins

Always round down to the nearest whole number. If you bowl a 172 game, your adjusted score would be 172 + 57 = 229.

Frequently Asked Questions

Bowling handicap is calculated using the formula: Handicap = (Basis Score - Your Average) × Percentage Factor. For example, if the basis is 220, your average is 160, and the percentage is 90%, your handicap would be (220-160) × 0.90 = 54 pins per game.

A 150 average is considered recreational to intermediate level. It's above the national average for casual bowlers (around 130-140) but below typical league bowlers (170-200). With practice, a 150 bowler can improve significantly by focusing on spare conversion and consistent releases.

The 90% means you receive 90% of the difference between the basis score and your average. This percentage factor determines how much of the gap is compensated. Higher percentages (like 100%) provide more handicap to lower-average bowlers, while lower percentages (like 80%) favor higher-average bowlers slightly.

Yes, a 170 average is considered good and places you in the competitive amateur range. Most league bowlers average between 150-180, so 170 puts you in the upper tier of recreational players. To reach 200+, focus on strike percentage and converting difficult spares.

Check with your league officials for the exact rules. Common configurations are 90% of 220 (most popular), 80% of 230, or 100% of 200. The basis is typically set higher than any bowler's average in the league, usually between 200-230.
