A golf handicap is a number that measures your demonstrated ability, so golfers of different skill levels can compete fairly. Under the World Handicap System it is called a Handicap Index. On a given course, it converts into the number of strokes you get. A 20-handicap playing a scratch golfer gets roughly 20 shots back over 18 holes.
How is a handicap calculated?
Since 2020, golf has used one World Handicap System (WHS), which replaced six different systems around the world. The USGA explains the math in three steps.
1. Every round becomes a Score Differential.
Score Differential = (113 / Slope Rating) x (Adjusted Gross Score - Course Rating - PCC adjustment)
Course Rating is what a scratch golfer is expected to shoot. Slope Rating measures how much harder the course plays for everyone else (113 is average). PCC, the Playing Conditions Calculation, adjusts for days when weather or setup pushed scores up or down.
2. Your Handicap Index is the average of your best 8 Score Differentials from your most recent 20 rounds. Soft and hard caps limit how fast it can rise in a 12-month period, and an exceptional score can bring it down quickly.
3. Your Course Handicap converts that Index for the course and tees you are playing:
Course Handicap = Handicap Index x (Slope Rating / 113) + (Course Rating - Par)
What is net double bogey?
For handicap purposes, the most you can count on any hole is a net double bogey: par plus two, plus any strokes you receive on that hole. A 12 on one blow-up hole will not wreck your Index.
How do you get a handicap?
In the US, you need a membership through a golf club or your state or regional Allied Golf Association. The USGA lets you sign up online and assigns you to your local association. Then you post scores. The USGA's Golf Handicap Information Network (GHIN) app is where most US golfers post rounds. You need 54 holes, in any mix of 9 and 18-hole rounds, to get your first Index.
What is an average golf handicap?
According to USGA data published in 2024, the average Handicap Index was 14.2 for men and 28.7 for women, across about 3.2 million US golfers who keep one. The maximum Handicap Index for anyone is 54.0.
Does equipment change your handicap?
Only through your scores. But the right gear helps higher handicaps most. Forgiving cavity back irons, a hybrid instead of long irons, and a shaft flex that matches your speed all take strokes off. Our guide on shaft flex is a good place to start, and a used full set is the cheapest way to get a matched bag. If you are brand new, read why beginners only need four clubs.
Where the word comes from
"Handicap" started as "hand in cap," a trading and betting game recorded in England by the 1650s. Two people put forfeit money in a cap, an umpire set the difference in value between the items being traded, and each player pulled out an open or closed hand to accept or refuse. The idea of evening out a contest moved into horse racing, where better horses carried extra weight, and the USGA says the word entered golf's vocabulary in the 1870s.
The practice is older than the word. The USGA's history of handicapping cites a diary entry by Thomas Kincaid from 1687 asking "whether it is better to give a man two holes of three" in a match, and minutes of the Honourable Company of Edinburgh Golfers from 1782 recording strokes given between players.
