How Golf Handicap Is Calculated
Formula
Score Differential = (Score - Course Rating) x 113 / Slope Rating
Handicap Index = Average of Best Differentials x 0.96
The official USGA system uses the best 8 of 20 most recent differentials. This simplified calculator uses 3 rounds to give an estimate.
What Slope and Course Rating Mean
Example Calculation
Calculate handicap from scores of 92, 88, and 95 on a course rated 72/125.
- 01Differential 1 = (92 - 72) x 113/125 = 20 x 0.904 = 18.08.
- 02Differential 2 = (88 - 72) x 113/125 = 16 x 0.904 = 14.46.
- 03Differential 3 = (95 - 72) x 113/125 = 23 x 0.904 = 20.79.
- 04Average = (18.08 + 14.46 + 20.79) / 3 = 17.78.
- 05Handicap Index = 17.78 x 0.96 = 17.1.
