6.1 Course Handicap Calculation

6.1a For an 18-hole Round

An 18-hole Course Handicap is calculated as follows:

Course Handicap = Handicap Index x (Slope Rating ÷ 113) + (Course Ratingpar)

Note: An 18-hole Course Handicap based on the same 9 holes is calculated as follows:

Course Handicap = Handicap Index x (9-hole Slope Rating ÷ 113) + (2 x 9-hole Course Rating – 2 x 9-hole par)

6.1b For a 9-hole Round

A 9-hole Course Handicap is calculated as follows:

Course Handicap = (Handicap Index ÷ 2) x (9-hole Slope Rating ÷ 113) + (9-hole Course Rating – 9-hole par)

(See Appendix E: Stroke Index Allocation for guidance on stroke index allocation for 9-hole rounds.)

Rule 6.1b Interpretations:

6.1b/1 – Use of 9-Hole Course and Slope Ratings in the Calculation of a 9-hole Course Handicap

When an Authorized Association issues Course Ratings and Slope Ratings to Golf Clubs, the 18-hole ratings should also be presented with front nine and back nine Course Ratings and Slope Ratings. For example:

The calculation of a 9-hole Course Handicap must use the correct Slope Rating for the 9-hole golf course being played.

Note: The calculated 18-hole and 9-hole Course Handicap is rounded to the nearest whole number, with .5 rounded upwards, for the purpose of:

Otherwise, the full calculated value is retained and rounding occurs only after the Playing Handicap calculation.
