Golf Handicap Calculator (WHS)
Work out score differentials and a Handicap Index from your recent rounds, using the World Handicap System formula and table.
Handicap Index
14.9
- Differentials used
- Lowest 1 of your 5 most recent
- Adjustment
- None
Enter adjusted gross scores (each hole capped at net double bogey). Your club's official index also applies the soft and hard caps and exceptional-score reductions, which need your full history.
Score differentials (✓ = counted)
| Round | Score | Rating / Slope | Differential | Counted |
|---|---|---|---|---|
| 1 | 92 | 71.8 / 131 | 17.4 | |
| 2 | 88 | 70.4 / 125 | 15.9 | |
| 3 | 95 | 72.1 / 133 | 19.5 | |
| 4 | 90 | 71.8 / 131 | 15.7 | |
| 5 | 86 | 69.9 / 122 | 14.9 | ✓ |

Score differential of each round, to 0.1
SD = (113 ÷ slope) × (score − course rating − PCC)
(113 ÷ 131) × (92 − 71.8); (113 ÷ 125) × (88 − 70.4); (113 ÷ 133) × (95 − 72.1); (113 ÷ 131) × (90 − 71.8); (113 ÷ 122) × (86 − 69.9) = 17.4, 15.9, 19.5, 15.7, 14.9
Take the lowest one (WHS table)
average = sum of the lowest differentials ÷ how many
14.9 ÷ 1 = 14.9
Add the adjustment, round to 0.1
index = average + adjustment
14.9 + 0 = 14.9
How it works
Score Differential = (113 ÷ Slope Rating) × (adjusted gross score − Course Rating − PCC), rounded to the nearest tenth; Handicap Index = average of the lowest 8 of your most recent 20 differentials (fewer rounds use the WHS Rule 5.2a table and adjustment), rounded to the nearest tenth, max 54.0
