Course handicap = Handicap Index × (Slope Rating ÷ 113) + (Course Rating − Par), rounded to the nearest whole number. Playing handicap = round(course handicap × allowance), using the 95% allowance that is standard for individual stroke play; other formats use different percentages. A score differential is (113 ÷ Slope Rating) × (gross score − Course Rating), shown to one decimal. A negative result is a plus handicap, where the player gives strokes back. Nine-hole rounds, mixed tees, exceptional score reductions and the Handicap Index averaging table are not modelled. Everything is calculated in this page.
