HANDICAP GURU: FIGURE IT OUT- Course Handicap Formula
If you can't find the handicap tables at a golf course but need to know
what your course handicap is, use a calculator. Multiply your Handicap Index by the Slope Rating of the tees you're going to play. Next, divide that number by the standard Slope of 113. Finally, round that figure off to a whole number (.5 rounds up). To give you an example, a golfer with a Handicap Index of 15.2 wants to know his course handicap for a set of tees with a Slope of 127. So he multiplies 15.2 and 127 to get 1,930.4. He then divides 1,930.4 by 113 to get 17.083. He then rounds that off to the nearest whole number. In this case, his course handicap is 17.
