1. What is a Golf Handicap Index?

The Handicap Index is a measure of a golfer's potential ability on a course of standard difficulty. It allows players of different skill levels to compete fairly by adjusting scores based on their demonstrated ability.

2. How Does the Calculator Work?

The calculator uses the official formula:

Where:

• Differentials — Your adjusted scores accounting for course difficulty
• Best 8 — The lowest 8 differentials from your most recent 20 rounds
• 0.96 — Multiplier to create a buffer against exceptional scores

Explanation: The system uses your best performances to measure your potential, not your average play.

3. Importance of Handicap Index

Details: A valid handicap index allows you to compete in tournaments, track your improvement, and play fair matches against golfers of different skill levels.

4. Using the Calculator

Tips: Enter your 20 most recent differentials (comma separated). The calculator will automatically select the best 8 and compute your handicap index.
