How Handicap Index Is Calculated
The World Handicap System (WHS) calculates your Handicap Index from Score Differentials. Each differential is: (Gross Score − Course Rating) × 113 ÷ Slope Rating
| Rounds Available | Differentials Used | Adjustment |
|---|---|---|
| 3 | Lowest 1 | −2.0 |
| 4 | Lowest 1 | −1.0 |
| 5 | Lowest 1 | 0 |
| 6 | Lowest 2 | −1.0 |
| 7–8 | Lowest 2 | 0 |
| 9 | Lowest 3 | 0 |
| 10–11 | Lowest 3 | 0 |
| 12–14 | Lowest 4 | 0 |
| 15–16 | Lowest 5 | 0 |
| 17–18 | Lowest 6 | 0 |
| 19 | Lowest 7 | 0 |
| 20 | Lowest 8 | 0 |
The final Handicap Index is the average of selected differentials × 0.96. This tool provides an estimate — post scores through your registered golf association for an official WHS Handicap Index.
