Golf Handicap Index Formula:
| From: | To: |
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 the average of your best 8 score differentials from your most recent 20 rounds and applies a 96% multiplier to determine your handicap index.
Details: A valid handicap index is essential for tournament play, establishing fair competition, tracking improvement, and setting realistic goals for golfers of all skill levels.
Tips: Enter your score differentials (one per line) from your recent golf rounds. The calculator will automatically select your best 8 differentials (or fewer if you have less than 8 entries) and compute your handicap index.
Q1: What is a score differential?
A: A score differential represents how well you played relative to the course difficulty. It's calculated based on your adjusted gross score, course rating, and slope rating.
Q2: How many differentials do I need?
A: For an official handicap index, you need at least 54 holes (3 rounds). The calculation uses your best 8 differentials from your most recent 20 rounds.
Q3: What is a good handicap index?
A: Scratch golfers have indexes around 0, while beginners might have indexes of 30+. Most recreational golfers range between 10-20.
Q4: How often should I update my handicap?
A: Handicaps should be updated after each round played under official conditions to maintain accuracy.
Q5: Why the 0.96 multiplier?
A: The 96% multiplier (bonus for excellence) ensures that your handicap reflects your potential ability rather than your average performance.
