Handicap Index Calculator - R&A
Differential = ((Adjusted score – Course rating) * 113) / Slope rating
A Handicap Index is calculated from the lowest Score Differentials in the scoring record. If a scoring record contains fewer than 20 Score Differentials, the table below is used to determine the number of Score Differentials to be included in the calculation and any adjustment that may apply. Round the result of the calculation to the nearest tenth.
