Standing on the first tee and asking, So, how many shots do I get? is one of golf's most common refrains. Whether it’s in a friendly match or a formal competition, knowing your handicap for the day is fundamental to a fair game. This guide will walk you through exactly how to determine the number of strokes you receive on any given course, breaking down the system into simple, understandable steps. You'll learn the key terms, see how the math works with clear examples, and understand how to apply those shots on the course to play your best.
What's a Handicap and Why Does it Matter?
In simple terms, a golf handicap is a numerical measure of a golfer's potential playing ability. Think of it as a head start that allows players of different skill levels to compete on an equal footing. It's the system that lets a weekend golfer have a competitive and fair match against a friend who plays every single day. Without it, the vast majority of matches would be one-sided.
The global standard is the World Handicap System (WHS), which ensures your handicap is fair, consistent, and portable wherever you play. Forget the old, complicated local systems, the WHS provides one streamlined method for everyone. The number of shots you get isn't a fixed number - it changes based on the difficulty of the course and the specific set of tees you’re playing from. Your job is simply to play your best, and the handicap system takes care of the rest.
The Building Blocks: Key Terms You Need to Know
Before you can calculate your shots, you need to understand three core components that form the foundation of the World Handicap System. You'll find two of these on the scorecard or on a board near the first tee.
Handicap Index®
This is your personal, portable number that represents your demonstrated golfing ability. It is not the number of shots you get on the course. Instead, it’s a verified average of the best 8 of your most recent 20 scores, converted into a decimal number (like 14.2 or 21.8). Your Handicap Index travels with you from course to course. You establish and maintain your Handicap Index by posting your scores after each round, usually through an official app like GHIN or a computer at your club.
Course Rating™
A Course Rating indicates the average score that a "scratch" golfer (someone with a 0 handicap) is expected to shoot on a particular course from a specific set of tees. For a par-72 course, a Course Rating might be something like 71.4. This means that, on average, a top-tier amateur is expected to shoot just a little under par on this course. If the rating were 73.5, it signifies that the course plays more difficult than its par for a scratch player.
Slope Rating™
This is often the most misunderstood term, but it’s a central piece of the puzzle. The Slope Rating measures the relative difficulty of a course for a "bogey" golfer (around an 18 handicap) compared to a scratch golfer. The number ranges from 55 to 155, with the average Slope Rating being 113.
- A course with a high Slope Rating (e.g., 140) is much more difficult for a bogey golfer than a scratch golfer. It likely has tight fairways, lots of hazards, and challenging greens. On these courses, a higher-handicap player will receive more strokes.
- A course with a low Slope Rating (e.g., 105) plays more similarly for all skill levels. It's more forgiving. On these courses, a higher-handicap player will receive fewer strokes than on a difficult course.
In short, Slope Rating levels the playing field between courses of varying difficulty.
The 2-Step Formula for Your Course Handicap
Now that you have the vocabulary down, figuring out your shots is a straightforward, two-step calculation. This result is called your Course Handicap - it's the exact number of strokes you get for your round on that day, from your chosen tees.
Step 1: Get Your Handicap Index, Course Rating, and Slope Rating
First, you need the three numbers we just discussed. Your Handicap Index can be found on your official handicap app or record. The Course Rating and Slope Rating are printed on the course's scorecard for each set of tees (e.g., Blue, White, Red).
Let’s imagine a golfer named Sarah. Her information is:
- Handicap Index: 18.5
- Tees: White Tees
- Slope Rating (from the scorecard): 125
Step 2: Calculate Your Course Handicap
The formula looks slightly intimidating at first, but it's just simple multiplication and division. The WHS has charts at every club that do this for you, but it’s good to know how it works.
The formula for Course Handicap is:
(Your Handicap Index) x (Slope Rating / 113) = Your Course Handicap
The "113" represents the average Slope Rating, so this formula is essentially adjusting your potential ability (Handicap Index) based on how much harder the course is than "average."
Let’s plug Sarah's numbers into the formula:
(18.5) x (125 / 113) = Course Handicap18.5 x 1.106 = 20.46
The result is always rounded to the nearest whole number (0.5 and up rounds up). So, Sarah's 20.46 becomes a Course Handicap of 20.
On this specific day, from the white tees, Sarah gets 20 strokes. If she were to play an easier course with a Slope Rating of 100, her Course Handicap would be 16 (18.5 x 100 / 113 = 16.3). This is the system in action - adjusting your strokes for the true difficulty of the test ahead.
A Note on Playing Handicap
For most friendly games, your Course Handicap is the number you'll use. However, when playing in certain competition formats (like Fourball or Foursomes), an extra calculation is done to determine your Playing Handicap. This involves applying a percentage allowance to your Course Handicap (e.g., 90% in team events) to ensure equity across formats. The competition organizer will almost always manage this for you, but it's good to be aware of the term.
"Okay, I Have My Shots...Now What?" Applying Strokes on the Course
You’ve done the math and you know you’re getting 20 shots. What does that actually mean hole by hole?
Look at your scorecard again. You’ll find a row labeled "Handicap," "HCP," or "Stroke Index" (S.I.). This row numbers the holes from 1 to 18.
- Stroke Index 1 is ranked as the hardest hole on the course.
- Stroke Index 18 is ranked as the easiest hole.
You apply your Course Handicap strokes according to this ranking, starting with the hardest hole. Since Sarah gets 20 strokes:
- She gets one stroke on every hole from 1 through 18. That accounts for 18 of her 20 shots.
- She has two strokes remaining (20 - 18 = 2).
- She gets these additional strokes on the two hardest holes: Stroke Index 1 and Stroke Index 2.
So, on the holes with an S.I. of 1 and 2, Sarah gets two strokes. On holes with an S.I. from 3 to 18, she gets one stroke.
This is how it works in a typical Stableford or net stroke play game. If a hole is a Par 4 and ranked as the hardest (S.I. 1), Sarah's personal "par" for that hole is a 6 (Par 4 + 2 strokes). If she makes a 6, she gets a net par. If another hole is a Par 5 and ranked S.I. 10, her personal par is 6 (Par 5 + 1 stroke).
Final Thoughts
Working out how many shots you get isn't meant to be complicated. Once you understand the core ideas of Handicap Index, Course Rating, and Slope Rating, it becomes a simple process of applying a formula and then distributing those strokes based on the hole rankings on your scorecard. This is the simple beauty of the World Handicap System - creating a fair and equitable game for everyone, everywhere.
