The number of strokes a player's Handicap Index converts to for one specific set of tees at one course, rounding to a single whole number used to set actual strokes on the card. It's calculated as Course Handicap = Handicap Index x (Slope Rating / 113) + (Course Rating − Par). Slope Rating, ranging from 55 to 155 with 113 as the neutral baseline, measures how much harder a course plays for a bogey golfer than a scratch golfer, so identical Indexes produce higher Course Handicaps on steeper slopes. The Course Rating minus Par term, folded into the formula in 2024, adjusts for tees that play harder or easier than their par independent of slope. A 10.4 Index on a 130 Slope, 71.5 Rating, par-71 course computes to 10.4 x (130/113) + 0.5, about 12.5, rounding to a 12 or 13 Course Handicap.
