Golf Slope & Handicap Calculator
This calculator helps golfers understand course difficulty and estimate their Handicap Differential for a single round — empowering you to play fairly on any course regardless of skill level. The standard course slope is exactly 113; anything higher means the course plays tougher for the bogey golfer relative to scratch.
Formula: ((Gross Score − Course Rating) × 113) ÷ Course Slope Rating
< 113
Course is easier than the standard baseline for bogey golfers.
113
Standard slope. The USGA-defined neutral difficulty.
> 113
Harder course. Expect higher differentials on this layout.
