1. What is a Golf Handicap Index?

The Handicap Index is a measure of a golfer's potential ability, calculated from the best 8 differentials of their last 20 scores multiplied by 0.96. It allows players of different skill levels to compete fairly.

2. How Does the Calculator Work?

The calculator uses the USGA Handicap formula:

Where:

• Differentials — (Adjusted Gross Score - Course Rating) × 113 / Slope Rating
• Best 8 — The lowest 8 differentials from last 20 scores
• 0.96 — Bonus for Excellence factor

Explanation: The system takes your best performances (lowest differentials) to measure your potential, not your average performance.

3. Importance of Handicap Calculation

Details: A proper handicap allows fair competition between golfers of different abilities and provides a benchmark for tracking improvement.

4. Using the Calculator

Tips: Enter at least 20 differential scores (comma separated). The calculator will automatically select the best 8 and compute your handicap index.

5. Frequently Asked Questions (FAQ)

Q1: Why multiply by 0.96?
A: The "bonus for excellence" factor slightly favors better players, encouraging improvement.

Q2: How often should I update my handicap?
A: Ideally after every round, but at least once every 20 rounds to maintain accuracy.

Q3: What's a good handicap index?
A: For men, <10 is good, <5 is excellent. For women, <15 is good, <10 is excellent.

Q4: Can I calculate a handicap with fewer than 20 scores?
A: Yes, but the formula adjusts: 5-6 scores = use lowest 1, 7-8 = lowest 2, etc.

Q5: Does handicap vary by course?
A: Your index is portable, but your course handicap adjusts for each course's difficulty.
