What Is the Golf Handicap Calculator?
The Golf Handicap Calculator helps golfers estimate their Handicap Index based on recent performance. This tool follows the World Handicap System (WHS), which takes into account the difficulty of the course and the player’s scores over time. It calculates your potential ability and allows for fair competition between players of different skill levels.
Score Differential = (113 ÷ Slope Rating) × (Adjusted Gross Score − Course Rating)
Course Handicap = Handicap Index × (Slope Rating ÷ 113) + (Course Rating − Par)
Playing Handicap = Course Handicap × Handicap Allowance
