Golf Handicap Index
Estimate your Golf Handicap Index based on course rating, slope rating, and gross scores.
Round 1
World Handicap System (WHS)
The World Handicap System levels the playing field, allowing golfers of different skill levels to compete fairly against one another.
How it's Calculated
Each score is converted into a Score Differential using the Course Rating and Slope Rating. The system then averages your lowest 8 differentials out of your most recent 20 rounds.
