How to Calculate Your Handicap
In order to calculate your handicap index, you will need a minimum of 5 golf scores (20 is ideal).
Step #1: Adjust Scores
Once you have 5 golf scores, you will then need to adjust those scores based on the maximum hole scores as stipulated by Equitable Stroke Control.
|Equitable Stroke Control|
|18-Hole Course Handicap||Maximum Number on any Hole|
|9 or less||Double Bogey|
|10 thru 19||7|
|20 thru 29||8|
|30 thru 39||9|
|40 or more||10|
Step #2: Calculate Differentials
Next, you need to calculate the differential for each of the adjusted scores. The differential for each score is calculated using the following formula:

Step #3: Determine Number of Differentials to Use
Next, determine the number of differentials to use based on the following chart:
|5 or 6||Lowest 1|
|7 or 8||Lowest 2|
|9 or 10||Lowest 3|
|11 or 12||Lowest 4|
|13 or 14||Lowest 5|
|15 or 16||Lowest 6|
Step #4: Calculate the Average Differential
Sum the lowest differentials and divide by the number of differentials used.
Step #6: Determine Index
Multiply the average differential from step #4 by 0.96 and drop any decimals after the 10th place. For example, if the result of multiplying the average differential by 0.96 is 12.234, your handicap index would be 12.2.
Step #7: Adjust Index If Necessary
The maximum handicap index is 36.4 for men, and 40.4 for women. So if your calculated index exceeds your maximum, use the maximum as your index.
How to Calculate Your Course Handicap
Once you have calculated your handicap index you will then need to convert it to a course handicap in order to apply your handicap to a scorecard. The course handicap formula is as follows:
