Golf Score Differential Calculator
Convert a single round into a score differential, the building block of your handicap index under the World Handicap System. The differential formula is one hundred and thirteen divided by the slope rating, multiplied by your adjusted gross score minus the course rating, plus any playing conditions adjustment. The number one hundred and thirteen is the standard slope of a course of average difficulty, so dividing by your course slope normalizes the round to a common scale. Enter your adjusted gross score, the course rating and the slope rating printed on the scorecard for the tees you played, add an optional conditions adjustment, and the tool returns your differential rounded to one decimal place. Collect these across several rounds and feed them into a handicap calculator. Everything is computed locally in your browser.
