Golf Handicap Explained in Plain English

2 October 2026 · 4 min read

A golf handicap is a number that shows how good a golfer is, so players of different abilities can compete fairly. The lower the number, the better the golfer. A scratch golfer has a handicap of 0. A beginner might be 36 or more.

In a match, the higher handicapper gets extra strokes to even things out. That's what makes golf unusual: a beginner and a strong player can have a genuinely close game.

What the number means

Roughly, your handicap is how many strokes over par you'd shoot on a good day on a course of average difficulty. A 15-handicap player who plays well might go round a par-72 course in about 87.

It's based on your better rounds, not your average. Most golfers score a few shots worse than their handicap on a typical day.

The World Handicap System

Since 2020, most of the golfing world has used the World Handicap System (WHS), run by the R&A and the USGA. It replaced six different systems with one, so a handicap means the same thing in Scotland, South Africa or the United States.

There are three numbers to know:

How your Handicap Index is calculated

1. Each round becomes a score differential, which compares your score with how hard the course is: (113 ÷ Slope Rating) × (Adjusted Gross Score − Course Rating).
2. Your Handicap Index is the average of your best 8 differentials from your last 20 rounds.
3. It updates every time you submit a new score.

Some definitions:

• Course Rating: what a scratch golfer is expected to shoot on that course, for example 71.4.
• Slope Rating: how much harder the course is for an average golfer than for a scratch golfer. It runs from 55 to 155, and 113 is average.
• Adjusted Gross Score: your score with very bad holes capped (see below).

To get a first Handicap Index, you usually need to submit scores from 54 holes: any mix of 18-hole and 9-hole rounds. The maximum Handicap Index is 54.0.

Net double bogey: the cap on bad holes

For handicap purposes, your maximum score on any hole is a net double bogey: par plus two, plus any handicap strokes you get on that hole. If you take a 10 on a par 4 where your limit is 7, you enter 7. It stops one disaster from wrecking your index.

From Handicap Index to Course Handicap

The same golfer gets different strokes on different courses, because some courses are harder than others:

Course Handicap = Handicap Index × (Slope Rating ÷ 113) + (Course Rating − Par)

Example: a Handicap Index of 12.0 on a course with a Slope of 130, a Course Rating of 72.3 and a par of 71:

• 12.0 × (130 ÷ 113) = 13.8
• plus (72.3 − 71) = 1.3
• = 15.1, which rounds to a Course Handicap of 15.

Most clubs post a chart by the first tee, or the app works it out for you.

How handicap strokes are used

Every hole on the scorecard has a stroke index from 1 (hardest) to 18 (easiest). With a Course Handicap of 15, you get one stroke on stroke index 1 to 15, and none on 16 to 18.

• Stroke play: take your Course Handicap off your total. A gross 90 with a handicap of 15 is a net 75.
• Match play: the higher handicap gets the difference between the two Course Handicaps, on the hardest holes.
• Stableford: take strokes off on each hole before working out points. See Stableford scoring explained.

Playing handicap allowances

In some formats, you play off a percentage of your Course Handicap, to keep things fair:

Do you need a handicap?

Not to play golf. You need an official one for most club competitions, and it's useful for any match against someone of a different standard. You can get one by joining a golf club or a national golf association, which submits your scores to the WHS.

Practise without a handicap

You don't need a handicap, a membership or a tee time to work on your short game. Mashy is a free browser golf game of short holes, chips and putts, scored against par on every hole. It's a quick way to learn how par, birdies and bogeys add up.
