Estimated Handicap Index
Handicap Index is calculated using your best score differentials.
Score Differential = (Adjusted Gross Score - Course Rating) × 113 / Slope Rating
Handicap Index = Average of Best Differentials × 0.96
How many differentials to use:
| Rounds Available | Best Differentials Used |
|---|---|
| 5–6 | Lowest 1 |
| 7–8 | Lowest 2 |
| 9–10 | Lowest 3 |
| 11–12 | Lowest 4 |
| 13–14 | Lowest 5 |
| 15–16 | Lowest 6 |
| 17–18 | Lowest 7 |
| 19 | Lowest 8 |
| 20 | Lowest 8 |
This is a simplified estimate. The official USGA/WHS system uses additional adjustments. Default course rating is 72 and slope is 113 (standard).
