how do you calculate handicap in golf
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.
