Handicap Index® Basis

  • The table to the left determines how many scores are used to compute the Handicap Index.
  • A minimum of five (5) rounds are required in order to compute a Handicap Index.
  • When a player records 20 rounds, the lowest 10 rounds are used to compute the player's Index which is then automatically adjusted for unusually low tournament scores over the past 12 months.
  • The USGAUnited States Golf Association system is designed to ensure competitive equity. The ideal would mean that if 100 amateurs, perfectly using this system, played 100 rounds, each player would win only one time.
  • The Handicap Index measures scoring potential, not scoring likelihood. The reality is that players only meet or better their course handicap 20% to 25% of the time.

Computing a Handicap Index

This table computes a single-round differential
Adjusted Gross Score minus the USGA Course Rating: 95 − 71.5 = 23.5
The difference x the Standard Slope Rating: 23.5 x 113 = 2655.5
The result is divided by the Course Slope Rating: 2655.5 / 125 = 21.24
This number is rounded to produce the single-round differential: 21.2

A Bonus for Excellence (.96) is then applied to the average of the 1 to 10 lowest differentials
Assume 9 rounds were posted with the 3 lowest differentials of: 21.2 + 16.4 + 24.3
The 3-round average is produced: 61.9 / 3 = 20.633
Apply the Bonus for Excellence: 20.633 x .96 = 19.8079
The result is truncated to one decimal point for a Handicap Index of: 19.8
