"What's your handicap?"
It's one of the first questions golfers ask each other. And if you don't have a good answer—or don't really understand what the number means—it can feel awkward.
Here's the truth: the handicap system is confusing at first, but the core concept is simple. This guide will give you a clear understanding of what a handicap is, how it works, and why it makes golf better for everyone.
What a Handicap Actually Represents
Your handicap is a measure of your potential, not your average.
A common misconception is that your handicap is your average score relative to par. It's not. The handicap system is designed to measure how well you play when you're playing well—your potential rather than your typical performance.
Think of it this way:
If you're a 15-handicap, you have the POTENTIAL to shoot about 15 over par on a course of average difficulty
You won't shoot that every time—maybe half the time you'll be worse
But on a good day, when things click, 15 over is roughly what you can do
This is why the calculation uses your best scores rather than averaging everything. The system assumes your bad rounds are "noise" and your good rounds reflect your actual ability.
What the numbers mean:

Important: These are rough guides for a standard difficulty course. Your actual score will vary based on course difficulty—which is where slope and rating come in.
Why Handicaps Exist: The Equalizer
Golf is unique among sports: a complete beginner can compete meaningfully against a skilled player.
The handicap system makes this possible. If I'm a 20-handicap and you're a 5-handicap, we can still have a fair match. I get 15 extra strokes distributed across the hardest holes. If we both play to our potential, the match is dead even.
This is the magic of golf. A father and son with vastly different abilities can compete. A corporate scramble can include the CEO who plays twice a year and the sales rep who plays twice a week. Office tournaments can be genuinely competitive.
Without handicaps, only golfers of similar skill could compete against each other. With handicaps, everyone can play everyone.
The GHIN System: Golf's Official Scorekeeper
GHIN stands for Golf Handicap and Information Network. It's the system managed by the USGA that tracks your scores and calculates your handicap.
How to Get a GHIN Handicap
Join a club or association that's affiliated with GHIN. This can be:
A private club (membership usually includes GHIN)
A public course golf association
A state or regional golf association (many offer "e-memberships" for $30-50/year)
Various golf organizations and leagues
Post your scores. After each round, enter your score into the GHIN system via:
The GHIN mobile app
The course's computer terminal
The GHIN website
Get your handicap index. Once you've posted enough scores (typically 3 rounds of 18 holes or 6 rounds of 9 holes), the system calculates your Handicap Index.
What Scores You Should Post
Post every round you play that's:
On a course with a valid Course Rating and Slope
At least 7 holes (9-hole scores count)
Played under normal conditions (not foot golf or extreme formats)
You should post scores from:
Casual rounds with friends
Tournament rounds
Rounds played alone
Good rounds AND bad rounds
You should NOT post:
Practice rounds where you hit multiple balls
Rounds on courses without official ratings
Scrambles or other non-standard formats where you're not playing your own ball
Be honest. The system only works if everyone posts accurate scores. Inflating your handicap to win competitions is called "sandbagging" and is both cheating and widely despised.
How Your Handicap Index Is Calculated
Here's where it gets a bit math-heavy. You don't need to memorize this, but understanding the concept helps.
The Basic Formula
Your Handicap Index is based on the best 8 of your last 20 rounds.
For each round, the system calculates a "Score Differential":
Score Differential = (Adjusted Gross Score - Course Rating) × 113 ÷ Slope Rating
Then:
Take your 8 lowest differentials out of your last 20 rounds
Average them
Multiply by 0.96 (a small reduction to account for potential improvement)
That's your Handicap Index.
Why This Matters
The calculation rewards your potential, not your average. Your best 8 of 20 represents how you play when you're playing well. The 12 worse rounds are essentially discarded.
This is intentional. Golf has high variance—bad bounces, off days, weather. The system filters out the noise and focuses on what you're capable of.
What If You Don't Have 20 Rounds?
The system adjusts based on how many scores you have:
Rounds PostedDifferentials Used3Lowest 1 - 2.04Lowest 1 - 1.05Lowest 16Lowest 2 - 1.07-8Lowest 29-11Lowest 312-14Lowest 415-16Lowest 517-18Lowest 619Lowest 720+Lowest 8
When starting out, your handicap can fluctuate significantly with each new round. After 20 rounds, it stabilizes as new scores push old ones out.
Equitable Stroke Control (ESC): Max Scores
Here's something many golfers don't know: you don't post your actual score if you blew up on a hole.
The Equitable Stroke Control system caps the maximum score you can post for any individual hole, based on your Course Handicap:
Course HandicapMax Score9 or lessDouble bogey10-19720-29830-39940+10
Example: If your Course Handicap is 18 and you take a 9 on a par 4, you post 7 (the max), not 9.
Why this exists: A blowup hole (we've all had them) doesn't represent your ability. If you're a 15-handicap who takes a 12 on one hole but plays the rest well, that 12 shouldn't tank your handicap. ESC limits the damage.
Important: You still PLAY the hole out. ESC only affects what you POST.
Course Rating: The Scratch Golfer Standard
Every rated golf course has a Course Rating—a number that represents the expected score for a scratch (0-handicap) golfer under normal conditions.
Example:
An easy course might have a Course Rating of 68.5
A tough course might have a Course Rating of 74.2
The Course Rating tells you: "If a scratch golfer played here, this is roughly what they'd shoot."
Key points:
Course Rating is NOT the same as par
A par-72 course might have a 69.8 rating (easier) or a 74.3 rating (harder)
The rating accounts for factors like length, hazards, green difficulty, and landing area size
Course Rating is measured to one decimal place and is calculated through a detailed evaluation process by authorized rating teams.
Slope Rating: How Hard It Is for YOU
Course Rating only tells half the story. A course might be easy for scratch golfers but brutal for high handicappers—or vice versa.
Slope Rating measures the relative difficulty of a course for bogey golfers (roughly 20-24 handicap) compared to scratch golfers.
The scale:
55 is the minimum (easiest for higher handicaps)
113 is "standard" difficulty
155 is the maximum (hardest for higher handicaps)
What slope actually measures:
A high slope (130+) means the course gets dramatically harder as skill decreases. Features like forced carries, narrow fairways, deep bunkers, and severe greens penalize weaker players more than strong players.
A low slope (100 or below) means the course is relatively friendly to higher handicaps—wide fairways, few hazards, bail-out areas.
Example:
A resort course with wide fairways and few hazards: Slope 115
A championship course with water on 12 holes and 150 bunkers: Slope 145
Both might be similarly challenging for a scratch golfer, but the championship course will be much harder for a 20-handicap.
Course Handicap: What You Actually Play To
Your Handicap Index is portable—it travels with you to every course. But each course is different, so you need to convert your index to a Course Handicap for the specific course and tees you're playing.
The formula:
Course Handicap = Handicap Index × (Slope Rating ÷ 113) + (Course Rating - Par)
You don't need to calculate this yourself. The GHIN app, course scorecards, and most GPS devices do it automatically.
Example:
You have a 15.0 Handicap Index. You're playing a course with:
Course Rating: 71.8
Slope Rating: 132
Par: 72
Course Handicap = 15.0 × (132 ÷ 113) + (71.8 - 72)
Course Handicap = 15.0 × 1.168 - 0.2
Course Handicap = 17.5 → 18 (rounded)
On this course, from these tees, you play as an 18-handicap. You get 18 strokes distributed across the holes (one stroke on holes ranked 1-18 in difficulty).
If you played the same course from easier tees (lower slope/rating), your Course Handicap would be lower.
How Handicap Strokes Are Distributed
On every scorecard, each hole has a "Handicap" or "HCP" number from 1 to 18. This ranks the holes by difficulty for handicap purposes.
Hole with HCP 1: Hardest hole for matching scores against a better player
Hole with HCP 18: Easiest hole for matching
If your Course Handicap is 12:
You get one stroke on holes ranked 1-12. On those holes, your "net" score is your actual score minus one.
If your Course Handicap is 20:
You get one stroke on all 18 holes, plus an extra stroke on the 2 hardest holes (HCP 1 and 2).
In match play:
The difference in handicaps determines strokes. If you're a 15 and your opponent is a 7, you get 8 strokes—on the 8 hardest holes (HCP 1-8).

Common Questions
"Do I need a handicap?"
You don't NEED one for casual golf. But it's useful if you:
Play in any organized events
Want to compete fairly with friends of different abilities
Want to track your improvement objectively
Ever travel to play golf (many courses ask for handicap)
"What if I don't post all my scores?"
Post them all. The system only works with honest, complete data. Cherry-picking rounds defeats the purpose and can get your handicap suspended.
"My handicap seems too high/low—what's wrong?"
The system is designed to reflect your POTENTIAL, not your average. If you rarely play to your handicap, that's normal—it represents your good rounds. If you regularly beat your handicap, you'll see it drop as you post those scores.
"Can I have a handicap if I only play 9 holes?"
Yes! Post your 9-hole scores. Two 9-hole scores combine into an 18-hole score differential for handicap purposes.
"What's a good handicap goal?"
This is personal, but:
Breaking 100 consistently (roughly 28 handicap) is a common first goal
Breaking 90 (roughly 18 handicap) means you're a solid golfer
Single digits (under 10) puts you in the top tier of amateurs
Scratch (0) is very rare—maybe 1-2% of golfers
Why This All Matters
The handicap system is one of golf's greatest innovations. It lets any golfer compete with any other golfer, regardless of skill level. It provides an objective measure of improvement over time. It creates a universal language for discussing ability.
Understanding your handicap—and the course rating and slope of where you play—makes you a more informed golfer. You'll know when you've played well relative to the difficulty, not just relative to par.
And most importantly, you'll never have to awkwardly shrug when someone asks, "So, what do you shoot?"
