Handicap Index Calculation 101
How is a Handicap Index calculated?
Once you have 20 scores in your scoring record, your Handicap Index is calculated by first averaging the best 8 Score Differentials out of your most recent 20 scores. This value may be adjusted due to built-in safeguards that are applied when:
- You submit an exceptional score, which is 7.0 strokes or better than your Handicap Index at the time the round is played, or
- Your 8 of 20 calculation is 3.0 or more strokes above your Low Handicap Index from the previous 365 days.
If either one of those safeguards are applied, it will be clearly identified in your scoring record. (Rule 5, Rules of Handicapping)
