Formula:

To determine your Course Handicap under the World Handicap System (WHS), given your Handicap Index, the formula is:

Course Handicap = Handicap Index × (Slope Rating / 113) + (Course Rating - Par)

  • Handicap Index: Your official Handicap Index.
  • Slope Rating: A measure of the relative difficulty of a course for a bogey golfer compared to a scratch golfer (typically 55-155).
  • Course Rating: An evaluation of the playing difficulty of a course for a scratch golfer.
  • Par: The standard number of strokes for the course.
  • 113: The neutral slope rating, a constant in the formula.

The result is typically rounded to the nearest whole number to give you the number of strokes you receive for that specific course.
