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

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 16 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
* 74 T 6/18 72.2/133 1.5
* 70 T 7/17 71.8/130 +1.6


Official USGA 'R' Handicap Index is calculated as follows.
Lowest Eligible Tournament Differential+1.6
Second Lowest Eligible Tournament Differential1.5
The second lowest differential is subtracted from the Official USGA Handicap Index0.9 - 1.5 = -0.6
Since -0.6 is less than 3.0 the index is not subject to T-Reduction.
