How to calculate
Calculate a score differential from adjusted score, course rating and slope rating.
Score differential = (score-rating)*113/slope
Worked example
Adjusted gross score: 90; Course rating: 72; Slope rating: 125.
Score differential: 16.27 .
Assumptions and limits
Official handicap systems use current rules, acceptable scores and multi-round procedures. This computes one simplified differential only.
Results are rounded for display; calculations use unrounded values. Read our calculation methodology.
Understanding the result
