| 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 their demonstrated capability.
The calculator uses the standard 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 skill levels. It reflects a player's potential rather than average performance.
Tips: Enter your score differentials (one per line) from your recent golf rounds. The calculator will automatically select your best 8 scores (or available number) and compute your handicap index. Score differentials should be positive numbers.
Q1: What is a score differential?
A: A score differential is calculated from your gross score adjusted for course rating and slope rating. It represents your performance relative to the course difficulty.
Q2: Why use only the best 8 of 20 scores?
A: This system emphasizes your potential ability by focusing on your better performances, providing a more accurate reflection of your true capability.
Q3: What does the 0.96 multiplier represent?
A: The 96% multiplier ensures the handicap index represents your potential ability rather than average performance, creating a fair system for competition.
Q4: How often should I update my handicap?
A: Handicaps should be updated regularly as you play new rounds. Most systems update daily when new scores are posted.
Q5: What's considered a good handicap index?
A: For men, below 10 is good, below 5 is excellent. For women, below 15 is good, below 10 is excellent. Scratch golfers have handicaps near 0.
