USGA HANDICAP INDEX CALCULATION
You have 20 scores available. Each score produces a differential which is calculated as follows: (Score - Rating) x 113 / Slope.
Based on your available scores, the following table will determine the score differentials to be used in calculating your Official USGA handicap Index.
Differentials To Use Table
| Scores Available | Differential(s) to Use |
|---|---|
| 20 | Lowest 10 |
| 19 | Lowest 9 |
| 18 | Lowest 8 |
| 17 | Lowest 7 |
| 15 or 16 | Lowest 6 |
| 13 or 14 | Lowest 5 |
| 11 or 12 | Lowest 4 |
| 9 or 10 | Lowest 3 |
| 7 or 8 | Lowest 2 |
| 5 or 6 | Lowest 1 |
Lowest 10 Differential(s)
| Used | Score | Type | Date | Rating/Slope | Differential |
|---|---|---|---|---|---|
| * | 90 | T | 14-8 | 70.4/125 | 17.7 |
| * | 84 | T | 14-6 | 68.7/125 | 13.8 |
| * | 86 | T | 14-5 | 68.5/128 | 15.4 |
| * | 82 | T | 14-4 | 68.6/122 | 12.4 |
| * | 90 | T | 13-9 | 69.8/124 | 18.4 |
| * | 92 | T | 13-9 | 69.9/128 | 19.5 |
| * | 89 | T | 13-9 | 68.8/125 | 18.3 |
| * | 90 | T | 13-7 | 70.9/123 | 17.5 |
| * | 86 | T | 13-5 | 70.1/126 | 14.3 |

| Official USGA Handicap Index is calculated as follows. | |||
| Differentials to Use for 20 Scores | 10 | ||
| Sum of 10 lowest differentials | 163.2 | ||
| Average based on 10 lowest differentials | 16.3 | ||
| Average multiplied by .96 (Bonus for Excellence) | 15.667 | ||
| Delete all digits after tenths | 15.6 | ||
| Official USGA Handicap Index | 15.6 | ||
TOURNAMENT REDUCTION 'R' CALCULATION
This calculation uses all the tournament scores played within the last 12 months or within your last 20-score history regardless of date played. These are called eligible tournament scores and there must be at least 2 eligible tournament scores to continue this calculation.
Your record contains 20 eligible tournament scores. The 2 tournament scores that produced the lowest differentials are listed below. These 2 lowest differentials are used to start the alternative calculation.
Lowest 2 Eligible Tournament Scores
| Used | Score | Type | Date | Rating/Slope | Differential |
|---|---|---|---|---|---|
| * | 84 | T | 14-6 | 68.7/125 | 13.8 |
| * | 82 | T | 14-4 | 68.6/122 | 12.4 |
| Official USGA 'R' Handicap Index is calculated as follows. | |||
| Lowest Eligible Tournament Differential | 12.4 | ||
| Second Lowest Eligible Tournament Differential | 13.8 | ||
| The second lowest differential is subtracted from the Official USGA Handicap Index | 15.6 - 13.8 = 1.8 | ||
| Since 1.8 is less than 3.0 the index is not subject to T-Reduction. | |||
