How it works

What is a Course Handicap?

Your Course Handicap is the number of strokes you actually receive at a specific course and set of tees. Your Handicap Index is portable; the Course Handicap converts it for how hard that particular course plays.

What is Slope Rating?

Slope measures how much harder a course plays for a bogey golfer than for a scratch golfer. It runs from 55 to 155, and a course of standard difficulty is 113 — which is why 113 sits in the formula.

What is Course Rating?

Course Rating is the score a scratch golfer is expected to shoot, in strokes (e.g. 72.4). Subtracting par from it accounts for a course that plays harder or easier than its par suggests.

What is the formula?

Course Handicap = Handicap Index × (Slope ÷ 113) + (Course Rating − Par), rounded to the nearest whole number. With slope alone you get a close estimate; add Course Rating and Par for the exact figure.
