You’ve probably noticed that not all golf courses are equal. Therefore, there has to be a method to equalize the disparity. A handicap index of 18 is not an 18 on every course. On a difficult course, it may be greater than 20.
Check your score card for the course rating and slope. (However, score cards aren’t always correct so you may want to check online when posting your score.) These usually are something like this – 71.6/122.
Course Handicap calculation:
(Current USGA Handicap Index x Slope) / 113
Example 1: A player with a 17.0 index playing from the red tees which have a slope rating of 122, she would have a calculated Course Handicap of:
17.0 x 122 / 113 = 18.35 or 18 ESC = 7
Example 2: A player with a 17.0 index playing from the white tees which have a slope rating of 131, she would have a calculated Course Handicap of:
17.0 x 131 / 113 = 19.70 or 20 ESC = 8
See the difference slope makes!
