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 Rating – par)

Notes:

  1. If an 18-hole round is being played over the same 9 holes from the same tees and there is no 18-hole Course Rating, the 18-hole Course Handicap 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)

  1. Rounding to the nearest whole number is the final step of the calculation.

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:

  • Applying adjustments for maximum hole score (see Rule 3.1 Maximum Hole Score for Handicap Purposes) and when a hole is not played (see Rule 3.2 When a Hole is Not Played).
  • Where applicable, calculating a Score Differential.

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