Golf Handicap Estimate
Golf handicap measures a player’s potential ability. The formula uses your best scores adjusted for course difficulty.
Handicap Differential formula:
Differential = (Score - Course Rating) × 113 / Slope Rating
Handicap Index (simplified for one round):
Index = Differential × 0.96
Key terms:
- Course Rating: The expected score for a scratch golfer (usually 68–74)
- Slope Rating: Course difficulty for bogey golfers (55–155, average is 113)
- Par: Standard score for the course (usually 72 for 18 holes)
Average scores by handicap:
| Handicap | Typical Score (par 72) |
|---|---|
| 0 (scratch) | 72 |
| 10 | 82 |
| 18 | 90 |
| 25 | 97 |
