How to calculate golf handicap differential
Golf handicap differential is a per-round measure of scoring performance relative to course difficulty, used to build a handicap index over time.
How the calculation works
Differential = Adjusted gross score − Course rating (this simplified version assumes a standard 113 slope rating; the full USGA formula also divides by slope rating × 113, which cancels out at exactly standard slope).
Example
An adjusted gross score of 92 on a course rated 71.5: 92 − 71.5 = 20.5.
Frequently asked questions
How is Handicap differential (assumes standard 113 slope) calculated?
Handicap differential (assumes standard 113 slope) = [Adjusted gross score] − [Course rating].

Pro Tips for Golf Handicap Differential
- The full official formula also incorporates the course's specific slope rating, which this simplified version assumes is standard (113) — for courses with a different slope, the differential would need that adjustment.
- A lower differential indicates a stronger relative performance, since it means scoring closer to (or better than) the course rating.
Common Golf Handicap Differential Mistakes to Avoid
- Using this simplified version for a course with an unusually high or low slope rating and treating the result as officially precise, when the full USGA formula would adjust for that.
