Handicap Index Formula:
| From: | To: |
The Handicap Index (HI) is a measure of a golfer's potential ability calculated from the best score differentials. It allows golfers of different skill levels to compete fairly by adjusting scores based on their demonstrated ability.
The calculator uses the simplified handicap formula:
Where:
Explanation: The formula takes the average of your score differentials and applies a 96% multiplier to calculate your playing handicap.
Details: A Handicap Index provides a standardized measure of a golfer's ability, enabling fair competition across different courses and skill levels. It helps track improvement and allows golfers to set realistic goals.
Tips: Enter your score differentials separated by commas. Score differentials represent the difference between your actual score and the course rating, adjusted for slope rating.
Q1: What are score differentials?
A: Score differentials are calculated as (113 / Slope Rating) × (Adjusted Gross Score - Course Rating). They normalize scores across different courses.
Q2: Why multiply by 0.96?
A: The 96% multiplier provides a buffer that favors the golfer and helps prevent handicap inflation by focusing on potential rather than average performance.
Q3: How many scores should I use?
A: For an accurate handicap, use your best 8 score differentials from your most recent 20 rounds, though this calculator works with any number of scores.
Q4: What is a good handicap index?
A: Scratch golfers have handicaps near 0, while beginners may have handicaps of 30+. Most recreational golfers have handicaps between 10-20.
Q5: How often should I update my handicap?
A: Handicaps should be updated after each round to maintain accuracy. Most golf associations update handicaps daily or weekly.
