How it works
Subtract the course rating from the score, then multiply by 113 divided by the course slope.
The 113 is the standard slope, the slope of a course of average difficulty. The result is the basic figure before any adjustments a league or club may apply.
Worked example
A score of 88 on a course rated 71.4 with a slope of 128 gives a differential of 14.7.
Questions
What is an adjusted score?
It is the total score with any hole scores capped at a set maximum, depending on the rules in play. Enter the adjusted figure you have.
Is a lower differential better?
A lower differential means a better round, measured against the course's rating and slope.
Does weather or the tees change it?
The sum uses only the rating and slope you enter. Pick the figures for the tees you actually played.
