Understanding how your golf handicap is calculated helps you track your progress and improve your game. The GHIN handicap formula uses a standardized approach recognized by the USGA.
Handicap Index = (Gross Score - Course Rating) × 113 / Slope RatingThis formula calculates your score differential, which represents how well you played relative to the course difficulty. The number 113 is the standard slope rating.
Course Handicap = Handicap Index × (Slope Rating / 113) + (Course Rating - Par)Your course handicap adjusts your handicap index for the specific course you're playing, accounting for both slope rating and the difference between course rating and par.
