A handicap lets golfers of different abilities compete fairly. It is one of the things that makes golf unique: a beginner and an experienced club golfer can play a genuinely close match, because the handicap system gives the less experienced player extra strokes.
Golfers around the world now use a single method — the World Handicap System (WHS), administered by golf's governing bodies and national associations. It replaced the different systems that countries used previously, so a handicap means the same thing wherever you play. Here is how it works, without the jargon.
Why handicaps matter
- Fair competition. Golfers of different abilities can compete in the same events and matches.
- Portability. Your Handicap Index works at any course that has been rated.
- Tracking progress. A falling handicap is the clearest measure of improvement.
- Access. Some courses and competitions require a handicap.
The three numbers you need to know
- Handicap Index — your portable measure of ability, such as 18.4. It travels with you to every course.
- Course Rating — what a scratch (zero-handicap) golfer is expected to shoot on a course from a given set of tees, for example 71.8.
- Slope Rating — how much harder the course plays for a bogey golfer than for a scratch golfer. It ranges from 55 to 155, and 113 is average.
What is a scratch golfer?
A scratch golfer has a Handicap Index of around zero and would be expected to play to the Course Rating on any rated course.
What is a bogey golfer?
For rating purposes, a bogey golfer is a player with a Handicap Index of around 20 for men or 24 for women — roughly a golfer who averages a bogey per hole. Slope Rating measures how much more difficult the course is for this golfer than for a scratch golfer. Courses with lots of hazards, thick rough and forced carries usually have higher slopes because they punish less accurate players more.
Step 1: Every round produces a score differential
After each round you post, the system calculates a score differential:
Score Differential = (113 ÷ Slope Rating) × (Adjusted Gross Score − Course Rating − PCC)PCC is the Playing Conditions Calculation, a small adjustment (usually 0) applied when conditions made scoring unusually hard or easy that day — for example, in strong winds or very wet conditions.
Example: you shoot an adjusted 92 on a course with a Course Rating of 71.8 and a Slope of 128.
(113 ÷ 128) × (92 − 71.8 − 0) = 0.883 × 20.2 = 17.8
You can try this yourself with the handicap calculator.
Why the differential matters
The differential converts your score into a standard measure, taking into account the difficulty of the course. A 92 on a hard course might produce a lower differential than an 88 on an easy one. That is what makes your handicap portable.
Step 2: Adjusting your score with net double bogey
For handicap purposes, the most you can count on any hole is a net double bogey: par of the hole + 2 + any handicap strokes you receive on that hole.
So if you receive one stroke on a par 4, your maximum score for handicap purposes is 4 + 2 + 1 = 7, even if you actually took 9. This stops one disaster hole from distorting your handicap.
Before you have a handicap
If you do not yet have a Handicap Index, the maximum score on each hole when building your first handicap is par + 5.
Holes you did not finish
If you do not complete a hole — for example, you pick up in a casual round — you record the score you would most likely have made. That score cannot exceed net double bogey.
Step 3: Your Handicap Index is the average of your best 8 of 20
Once you have 20 scores, your Handicap Index is the average of your best 8 score differentials from your most recent 20 rounds.
Using the best 8 rather than all 20 reflects your potential rather than your average. That is why most golfers shoot above their handicap on a typical day — you would expect to play to your handicap or better only occasionally.
If you have fewer than 20 scores
A sliding scale uses fewer differentials (with small adjustments) until you build up a full record:
| Number of scores | Differentials used | Adjustment |
|---|---|---|
| 3 | Lowest 1 | −2.0 |
| 4 | Lowest 1 | −1.0 |
| 5 | Lowest 1 | 0 |
| 6 | Average of lowest 2 | −1.0 |
| 7–8 | Average of lowest 2 | 0 |
| 9–11 | Average of lowest 3 | 0 |
| 12–14 | Average of lowest 4 | 0 |
| 15–16 | Average of lowest 5 | 0 |
| 17–18 | Average of lowest 6 | 0 |
| 19 | Average of lowest 7 | 0 |
| 20 | Average of lowest 8 | 0 |
The maximum Handicap Index is 54.0, which allows beginners to get a handicap and take part in competitions early in their golfing life.
Safeguards in the system
The system also includes safeguards:
- Soft and hard caps limit how quickly your index can rise compared with your lowest index over the past year. This stops a temporary loss of form from inflating your handicap too far.
- Exceptional score reduction lowers your index immediately if you post a score at least 7 strokes better than your current index.
- Daily updates mean your index updates the day after you post a score, so it reflects your current form.
Step 4: Converting to a Course Handicap
Your Handicap Index is converted into a Course Handicap for the specific course and tees you are playing:
Course Handicap = Handicap Index × (Slope Rating ÷ 113) + (Course Rating − Par)Example: with a Handicap Index of 18.4 on a course with a Slope of 128, a Course Rating of 71.8 and a par of 72:
18.4 × (128 ÷ 113) + (71.8 − 72) = 20.84 − 0.2 = 20.64 → 21 strokes
That means you receive one stroke on every hole, plus a second stroke on the three hardest holes (stroke index 1–3).
Different tees, different handicaps
Because each set of tees has its own Course Rating and Slope, your Course Handicap changes depending on which tees you play. Longer, harder tees give you more strokes. Courses often display a Course Handicap table near the first tee or in the clubhouse.
Step 5: Playing Handicap for competitions
For competitions, a handicap allowance may then be applied — for example 95% of Course Handicap in individual stroke play, or 85% in four-ball stroke play. The result is your Playing Handicap. Committees set these allowances, so check the competition terms.
| Format | Common recommended allowance |
|---|---|
| Individual stroke play | 95% |
| Individual Stableford | 95% |
| Four-ball stroke play | 85% |
| Singles match play | 100% |
| Four-ball match play | 90% |

How strokes are allocated: stroke index
Every hole on a scorecard has a stroke index from 1 to 18. Stroke index 1 is generally the hardest hole (relative to par) and 18 the easiest.
- With a Playing Handicap of 10, you receive a stroke on holes with stroke index 1–10.
- With 18, you receive one stroke on every hole.
- With 24, you receive one stroke on every hole and two strokes on holes 1–6.
In match play, the player with the higher handicap usually receives the difference between the two Playing Handicaps, allocated by stroke index.
How to get a handicap
- Join a golf club or an authorised golf association in your country. Some associations offer handicap memberships without a home course.
- Submit scores from rated courses. Both 9- and 18-hole rounds can count.
- Post your first scores — usually enough to make up 54 holes — and your Handicap Index will be calculated automatically.
- Keep posting scores after every acceptable round, home and away.
See our golf club membership guide for help choosing a club.
What counts as an acceptable score?
Generally, rounds played under the Rules of Golf, on a rated course, in an authorised format, with another player present to verify the score. Both competition and general play (social) rounds can usually count, provided you register them in advance where your association requires it.
Nine-hole scores
Nine-hole scores can count towards your handicap. In many countries, a nine-hole score is combined with an expected score for the other nine holes to produce an 18-hole differential. This makes it easier for busy golfers to keep an up-to-date handicap. See fitting golf into a busy life.
Common misconceptions
- "My handicap is my average score over par." No — it reflects your best 8 of 20, so your average score will usually be several shots higher.
- "I should play to my handicap every time." Most golfers play to their handicap only occasionally.
- "Only competition scores count." In most countries, social rounds can also count if submitted correctly.
- "A higher handicap is an advantage." Deliberately inflating a handicap is against the spirit of the game and can lead to penalties from your club.
- "The handicap system is too complicated." You only need to post accurate scores — the system does the maths.

Frequently asked questions
What is a good golf handicap?
It depends on your goals. Many club golfers have handicaps between 10 and 28. A handicap below 10 is considered very good, and a scratch handicap is rare among amateurs.
How many rounds do I need for a handicap?
You need scores totalling 54 holes — any combination of 9- and 18-hole rounds — to receive your first Handicap Index.
Does my handicap change at every course?
Your Handicap Index stays the same, but your Course Handicap changes depending on the course and tees, because each has its own Course Rating and Slope Rating.
Can I get a handicap without joining a club?
In many countries, yes. Some golf associations offer handicap memberships for golfers without a home club. Check with your national association.
What is the difference between Course Handicap and Playing Handicap?
Your Course Handicap is the number of strokes you receive for a particular course and tees. Your Playing Handicap applies any competition allowance, such as 95%, to the Course Handicap.
The bottom line
The World Handicap System sounds complicated, but the principle is simple: each round produces a differential adjusted for course difficulty, your Handicap Index is the average of your best eight from twenty, and you convert it into a Course Handicap for wherever you play. Post your scores honestly, use net double bogey and let the system do the maths. Once you have a handicap, you can compete in club events, play fair matches against friends of any ability and — best of all — track your improvement with a single number.
