| 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 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 0.96 multiplier to slightly favor better performance.
Details: The handicap index provides a standardized way to measure golfing ability, enabling fair competition across different courses and skill levels. It's essential for tournament play and tracking improvement over time.
Tips: Enter your score differentials from your last 20 rounds as comma-separated values. The calculator will automatically select the best 8 scores and compute your handicap index.
Q1: What is a score differential?
A: Score differential is calculated based on your adjusted gross score, course rating, and slope rating. It represents your performance relative to the course difficulty.
Q2: Why use only the best 8 of last 20 rounds?
A: This system focuses on your potential ability rather than average performance, rewarding consistency and peak performances.
Q3: What does the 0.96 multiplier do?
A: The "bonus for excellence" multiplier slightly reduces the handicap index, making it more challenging to maintain a low handicap and rewarding skilled players.
Q4: How often should I update my handicap?
A: Handicaps should be updated after each round to maintain accuracy. Most golf associations provide daily handicap revisions.
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.
