Handicaps are mathematical equalizers, making it possible for golfers of various skill levels to compete on even footing. It starts with your handicap index, a number that indicates how many strokes you use compared with a golfer who shoots near par and doesn't need a handicap. You then convert that handicap index into a specific course handicap that is based on the difficulty of each course you play.
Find Your Handicap Differential and Index
Step 1
Find your final score for one of the last five rounds of 18-hole golf you have played. According to the United States Golf Association's Handicap Manual, at least five final scores need to be posted for a player to receive an official handicap.
Step 2
Find the course rating and slope rating for that particular course. The course rating is the USGA's numerical evaluation of how difficult that course is for someone who shoots at or near par, called a "scratch golfer." The slope rating is the USGA's measure of how difficult the course is for a non-scratch golfer. Both of these numbers usually appear on the course's score cards; in a pinch, call the course's pro shop and ask.
Step 3
Subtract the course rating from your final score.
Step 4
Multiply that figure by 113, the USGA's average slope rating.
Step 5
Divide the result by the course's actual slope rating. Keep track of this number---it's called the "differential," and you will need it again.
Step 6
Repeat these steps for four more rounds you have played.
Step 7
Look at the five numbers you calculated in step 5. Take the lowest differential and multiply it by 0.96 to find your handicap index. This should be a one- or two-digit number with a decimal to the tenth place.
Use Your Handicap Index to Play
Step 1
Start every new round of golf by finding your course handicap. Multiply your handicap index by the slope rating of a course and divide by 113. Round off any decimals to the nearest whole number, according to USGA rules.
Step 2
Play the round using the USGA's rules for equitable stroke control. According to the Handicap Manual, the maximum number of shots allowed per hole will change based on your handicap. If your handicap is 10 through 19, for example, you're allowed a maximum of seven shots per hole.
Step 3
Subtract your course handicap from your final score to get your adjusted score. The golfer with the lowest adjusted score is the winner.
Tips and Warnings
- The maximum handicap permitted by the USGA is 36.4 for men and 40.4 for women.
