What is a Golf Handicap?

A golf handicap is a numerical measure of a golfer's potential playing ability based on recent scores, course ratings, and slope ratings. It's used to level the playing field so golfers of different skill levels can compete fairly. The lower your handicap, the better your golfing ability. Handicaps are recognized worldwide and are essential for tournaments, club play, and tracking your progress.

How is Golf Handicap Calculated? (Formula Explained)

The World Handicap System uses the following formula for each round:

Handicap Differential = (Score - Course Rating) × 113 / Slope Rating

After calculating differentials for each round, the best differentials are averaged (number used depends on rounds entered), and the result is rounded to one decimal place for your handicap index.

Score: Your total strokes for the round.
Course Rating: Difficulty for a scratch golfer (from the scorecard).
Slope Rating: Difficulty for a bogey golfer (55–155).

Example: Golf Handicap Calculation Step-by-Step

Suppose Sarah plays 3 rounds with the following scores and course details:

Round 1: Score 90, Course Rating 72.0, Slope 113
Round 2: Score 92, Course Rating 71.5, Slope 120
Round 3: Score 88, Course Rating 73.2, Slope 110

Calculate each differential:

Round 1: (90 - 72.0) × 113 / 113 = 18.0
Round 2: (92 - 71.5) × 113 / 120 ≈ 19.3
Round 3: (88 - 73.2) × 113 / 110 ≈ 15.2

Average the best differentials (all 3 in this case): (18.0 + 19.3 + 15.2) / 3 ≈ 17.5

Sarah's handicap index is 17.5.
