WHS Handicap Index Formula:
| From: | To: |
The WHS (World Handicap System) Handicap Index is a measure of a golfer's demonstrated ability calculated against the slope rating of a golf course of standard playing difficulty. It allows golfers of different abilities to compete on an equitable basis.
The calculator uses the WHS Handicap Index formula:
Where:
Explanation: The system takes your best 8 score differentials from your last 20 rounds, averages them, and applies a 96% multiplier to determine your Handicap Index.
Details: The Handicap Index provides a standardized measure of a golfer's potential ability, allowing fair competition across different courses and skill levels. It's essential for tournament play and tracking improvement over time.
Tips: Enter at least 8 score differentials separated by commas. The calculator will automatically select the best (lowest) 8 values and compute your Handicap Index according to WHS rules.
Q1: What is a Score Differential?
A: A Score Differential is calculated from your gross score, course rating, and slope rating. It represents your performance adjusted for course difficulty.
Q2: Why use only the best 8 of 20 rounds?
A: This system focuses on your potential ability rather than average performance, rewarding consistency and peak performances.
Q3: What is the purpose of the 0.96 multiplier?
A: The "Bonus for Excellence" multiplier slightly reduces the handicap index, encouraging continued improvement and ensuring handicaps reflect potential rather than average performance.
Q4: How often should I update my handicap?
A: Handicaps should be updated after every acceptable round, with most systems updating 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 indexes around 0.
