From: | To: |
The Golf Handicap Index (HI) is a numerical measure of a golfer's potential ability based on their recent scores. It allows players of different skill levels to compete fairly by adjusting scores based on course difficulty and player ability.
The calculator uses the World Handicap System formula:
Where:
Explanation: The system takes your best 8 score differentials from your last 20 rounds, averages them, and applies a 0.96 multiplier to calculate your Handicap Index.
Details: A Handicap Index provides a standardized measure of playing ability that travels with you to any golf course. It's essential for tournament play, fair competition, and tracking improvement over time.
Tips: Enter your score differentials (one per line). You need at least 8 score differentials for an accurate calculation. Score differentials should be calculated as: (113 ÷ Slope Rating) × (Adjusted Gross Score - Course Rating - PCC adjustment).
Q1: How many scores do I need to establish a Handicap Index?
A: You need a minimum of 54 holes comprised of 9-hole or 18-hole scores (typically 3-18 hole scores or equivalent combination).
Q2: What is the maximum Handicap Index?
A: The maximum Handicap Index is 54.0 for both men and women under the World Handicap System.
Q3: How often is the Handicap Index updated?
A: Handicap Indexes are updated daily after the submission of an acceptable score.
Q4: What is a Score Differential?
A: A Score Differential measures your performance relative to the course difficulty, calculated as: (113 ÷ Slope Rating) × (Adjusted Gross Score - Course Rating - PCC adjustment).
Q5: Why is there a 0.96 multiplier?
A: The 0.96 "Bonus for Excellence" multiplier slightly reduces the handicap index, encouraging improvement and ensuring handicaps better reflect potential ability.
