| From: | To: |
The Golf Handicap Index (HI) 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 their demonstrated capability.
The calculator uses the official Handicap Index formula:
Where:
Explanation: The formula calculates the average of your best 8 score differentials from your most recent 20 rounds, then applies a 96% multiplier to determine your official 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 fair competition, tournament play, and tracking improvement over time.
Tips: Enter your score differentials as comma-separated values. The calculator will automatically select the best 8 differentials (lowest values) and compute your handicap index according to official rules.
Q1: What is a score differential?
A: A score differential represents your adjusted gross score relative to the course rating and slope. It's calculated as: (113 / Slope Rating) × (Adjusted Gross Score - Course Rating).
Q2: Why use only the best 8 of 20 scores?
A: This system focuses on your potential ability rather than average performance, rewarding consistency and peak performance while allowing for occasional poor rounds.
Q3: What does the 0.96 multiplier do?
A: The 96% multiplier ensures the handicap index represents your potential ability rather than your average performance, making competitions more equitable.
Q4: How often should I update my handicap?
A: Handicaps should be updated after each round played under official conditions. Most systems update daily or weekly.
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.
