1. What Is WHS Golf Handicap Calculation?

The World Handicap System (WHS) provides a unified handicap system used in the UK and internationally. The Handicap Index (HI) is calculated from your best 8 Score Differentials (SD) out of your most recent 20 scores.

2. How Does The Calculator Work?

The calculator uses the WHS Handicap Index formula:

Where:

• \( HI \) — Handicap Index (unitless)
• \( SD \) — Score Differential (unitless)
• 8 — Number of best scores used
• 0.96 — Buffer factor to ensure handicap represents potential ability

Explanation: The system takes your best 8 Score Differentials from your last 20 rounds, calculates the average, then applies a 96% multiplier to determine your playing handicap.

3. Importance Of Handicap Index Calculation

Details: The Handicap Index allows golfers of different abilities to compete fairly. It represents a player's demonstrated ability and potential, updated after each round to reflect current form.

4. Using The Calculator

Tips: Enter your 8 best Score Differentials, one per line. Score Differential is calculated as: (Adjusted Gross Score - Course Rating) × 113 ÷ Slope Rating.

5. Frequently Asked Questions (FAQ)

Q1: What is a Score Differential?
A: Score Differential adjusts your gross score for course difficulty using Course Rating and Slope Rating: (AGS - CR) × 113 ÷ SR.

Q2: Why use only the best 8 of 20 scores?
A: This system focuses on your potential ability rather than average performance, using your best performances to determine handicap.

Q3: What is the purpose of the 0.96 multiplier?
A: The 96% multiplier ensures your handicap reflects your potential ability rather than your average performance.

Q4: How often is the Handicap Index updated?
A: The Handicap Index is updated daily, taking into account your most recent 20 scores and recalculating based on the best 8.

Q5: Is the WHS system used throughout the UK?
