Handicap Index Formula:
| From: | To: |
The Handicap Index is a measure of a golfer's potential ability under the World Handicap System (WHS). It represents the number of strokes a player needs to play to par on a course of standard difficulty.
The calculator uses the WHS 2022 formula:
Where:
Explanation: The formula takes the average of your best 8 score differentials from your last 20 rounds and applies a 0.96 multiplier to slightly favor better performance.
Details: The Handicap Index allows golfers of different skill levels to compete fairly. It's used worldwide under the WHS to ensure consistent handicap calculation across different courses and countries.
Tips: Enter your 8 best score differentials from your most recent 20 rounds. Score differentials should be positive numbers representing your performance relative to course rating and slope.
Q1: What is a score differential?
A: Score differential is calculated as: (113 / Slope Rating) × (Adjusted Gross Score - Course Rating - PCC adjustment). It normalizes scores across different courses.
Q2: Why use the best 8 out of 20 rounds?
A: This system ensures your handicap reflects your potential ability rather than your average performance, accounting for both consistency and peak performance.
Q3: What is the 0.96 multiplier for?
A: Known as the "Bonus for Excellence," this multiplier slightly reduces the handicap index, rewarding players who demonstrate better potential.
Q4: How often should I update my handicap?
A: Handicaps should be updated after each acceptable round. The system uses your most recent 20 rounds, with new scores replacing older ones.
Q5: Is this calculation the same worldwide?
A: Yes, the WHS formula is standardized globally, ensuring consistent handicap calculation across all member countries.
