It accuately appraises golfers abilities that they can manage competition balance with their own position.

3. Golf Handicap Calculation
- Step 1 :
A minimum of five scores and a maximum of 20 is required to get started. Remember, when posting scores for handicaps, you must your adjusted gross scores. For each score, the USGA Course Rating and Slope Rating for the courses played are also required. Using those figures, calculate the handicap differential for each round entered using this formula:
(Score - Course Rating) x 113 / Slope Rating
For example, lets say the score is 85, the course rating 72.2, the slope 131. The formula would be (85 - 72.2) x 113 / 131.
This differential is calculated for each round entered.
(Note: The number 113 represents the slope rating of a golf course of average difficulty, as set by the USGA.)

- Step 2
Figure out how many differentials are being used. Not every differential that results from Step 1 will be used in the next step. If only five rounds are entered, only the lowest differential will be used. If 20 rounds are entered, only the 10 lowest differentials are used. A chart at the bottom of this page shows how many differentials are used based on the number of rounds entered.

- Step 3
Get an average of the differentials used by adding them together and dividing by the number used (i.e., if five differentials are used, add them up and divide by five).
Multiply the result by .96 (96-percent). Drop all the digits after the tenths (do not round off) and the result is handicap index.
Thankfully, you dont have to do the golf handicap calculation on your own. Your golf clubs handicap committee will handle it for you. You can also use our free handicap index calculator - give it a try!
