| From: | To: |
The Golf Handicap Index is a numerical measure of a golfer's potential ability. It allows players of different skill levels to compete fairly by adjusting scores based on course difficulty and player ability.
The calculator uses the official Handicap Index formula:
Where:
Explanation: The formula takes the average of your best 8 score differentials from your most recent 20 rounds and applies a 96% multiplier to determine your playing handicap.
Details: A Handicap Index provides a standardized way to measure golfing ability, enabling fair competition across different courses and among players of varying skill levels. It's essential for tournament play and tracking improvement.
Tips: Enter your score differentials (one per line) from your recent golf rounds. The calculator will automatically select the best 8 differentials and compute your Handicap Index. For accurate results, enter at least 8 score differentials.
Q1: What is a Score Differential?
A: A Score Differential measures your performance relative to the course rating and slope. It's calculated as: (Adjusted Gross Score - Course Rating) × 113 / Slope Rating.
Q2: Why use only the best 8 out of 20 scores?
A: This system focuses on your potential ability rather than average performance, rewarding consistency and peak performances.
Q3: What does the 0.96 multiplier mean?
A: The "Bonus for Excellence" multiplier (96%) ensures that your handicap reflects your potential best performance rather than your average performance.
Q4: How often should I update my handicap?
A: Handicaps should be updated after each round. Most golf associations update handicaps daily or weekly based on submitted scores.
Q5: What's considered a good handicap index?
A: For men, 0-9 is excellent, 10-19 is good, 20-29 is average. For women, 0-14 is excellent, 15-24 is good, 25-36 is average. Scratch golfers have handicaps near 0.
