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 standard handicap index formula:
Where:
Explanation: The formula takes your best 8 score differentials from your most recent 20 rounds, averages them, and applies a 0.96 multiplier to calculate your official handicap index.
Details: The handicap index is essential for fair competition in golf. It levels the playing field by allowing golfers of different abilities to compete against each other on equal terms.
Tips: Enter at least 8 score differentials separated by commas. The calculator will automatically select the best 8 scores and compute your handicap index.
Q1: What is a Score Differential (SD)?
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 20 scores?
A: This system focuses on your potential ability rather than average performance, rewarding consistency and peak performances.
Q3: What does the 0.96 multiplier mean?
A: The "Bonus for Excellence" factor slightly reduces the handicap index, encouraging improvement and ensuring handicaps reflect true potential.
Q4: How often should I update my handicap?
A: Handicaps should be updated after each round to maintain accuracy. Most golf associations require monthly updates at minimum.
Q5: What's a good handicap index?
A: For men, 0-9 is excellent, 10-19 is good, 20-29 is average. For women, add about 10 to these ranges. Scratch golfers have handicaps near 0.
