Handicap Differential. First, you determine the handicap differential for each round of golf you played, up to the last 20 rounds. Subtract the USGA course rating from your score. Take the difference and multiply it by the standard USGA slope rating, which is 113.Then divide that number by the course's slope rating.andicap Index. To calculate your handicap index, you average a certain number of your best handicap differential scores, depending on how many scores you have accumulated. Ideally, you want 20 scores, so you can use the lowest 10 of the last 20.
For each score posted, a handicap differential is calculated. The formula is: Handicap Differential = (Adjusted Gross score â USGA/SCGA Course Rating) x 113 / USGA/SCGA Slope Rating. Using this example: 1  Billâs adjusted gross score was 95 at a course with 73.5/130 (Course Rating/Slope Rating).: I just joined a club and already have 18-hole scores in my score file but my file still shows NH. Your score file will show NH (no Handicap Index) until it goes through a revision on the 1st or 15th of the month.
