Hey all—William here. This year I have been really focusing on my golf game and trying to get to the elusive mid-single digit handicap.I started this year at a 10.6, and after a lot of work, I’m down to an 8.4. While I have learned more about my swing and how I need to mentally approach the game, I realized how little I knew about the handicapping system, slope and course rating. I generally knew how it worked, but I didn’t realize how this could significantly impact your game.

To those who are unfamiliar or skip the fine print on the scorecard, slope and course rating are those mysterious numbers you see on every scorecard, usually near the tee boxes, that most people glance at and move on. But the more I play, the more I realize those numbers actually tell you a lot about the round you're about to have.

And if you’re trying to break 100, 90, or even 80—this stuff matters more than you think.

Let’s start here. Course rating is a number that measures the general length and obstacles and tells you what a scratch golfer (someone with a 0.0 handicap) is expected to shoot on a given course under normal playing conditions. The number usually falls somewhere between 67 and 75, depending on the difficulty of the course.

So if a course has a rating of 72.4, that means a scratch golfer would expect to shoot 72 (and change) from that set of tees. If the rating is 69.8, that scratch player should be going under par.

These ratings are calculated by the USGA and local Allied Golf Associations—like the Carolinas Golf Association here in South Carolina. And they don’t just guess. There are more than 460 different factors that go into these ratings. Seriously.

A few that stand out:

It’s a wild process, but the takeaway is simple: course rating is what a scratch golfer should expect to shoot, all things considered.

Now here’s where things get more relatable. Slope rating is a number that shows how much harder the course gets for a bogey golfer (someone with around a 20 handicap for men, or 24 for women) compared to a scratch golfer. This metric is based on the USGA’s bogey rating (we’ll get to that in a second) and looks at hazards, obstacles, and length that would most impact a bogey golfer (i.e,, hazards on wayward shots, etc). 

The scale runs from 55 to 155, but you’ll typically see numbers between 105 and 145. A slope of 113 is considered the average.

Higher slope? Tougher course. Lower slope? More forgiving.

So let’s take a look at the Furman University Golf Club from the Black Tees:

That course is going to feel a lot tougher for your average weekend warrior than it will for someone playing off scratch. And for someone like me—hovering in that single-digit zone—that’s good info to have when choosing tees or setting expectations. So, 131 gives us a metric to look at for how difficult a course is for us weekend warriors and the bogey rating should tell us what we can actually expect to shoot. 

This one doesn’t usually show up on scorecards, but it’s how slope rating is actually calculated. Think of bogey rating as the course rating… but for a bogey golfer.

Here’s how slope is calculated:

Slope = (Bogey Rating – Course Rating) × Constant
Constant = 5.381 for men, 4.240 for women

For example:

Slope = (96.04 – 71.7) × 5.381 = 131 (rounded)

This gives a more accurate picture of how tough the course feels for most of us—those who aren’t out there striping it like Rory every Saturday.

I tend to use my home course (Furman Golf Club) as a baseline. From the tees I usually play, the slope is 131. So when I head somewhere new, I check: is the slope higher or lower than Furman? That gives me a quick read on how the course might play—and whether I should expect to grind or go low.

You can also plug these numbers into the USGA’s Course Handicap formula:

Course Handicap = Handicap Index × (Slope ÷ 113)

So if your index is 8.4 and you’re playing a course with a slope of 131:

8.4 × (131 ÷ 113) ≈ 9.74

You’d round that to 10, meaning you get 10 strokes on that course; one stroke on each of the 10 hardest holes. 

Let’s say you shoot an 82 on a course with a 138 slope. That round might be better than a 78 on an easier track with a 115 slope. These numbers help explain the context behind the score—and they’re a big part of how the handicap system works fairly across different courses. That is why your handicap will really drop when you post a low score on a tough course or remain flat when that low score comes from an easy course. 

Golf is already hard enough—don’t make it harder by ignoring the info right in front of you. Course rating and slope rating are like little cheat codes built into the scorecard. The more you understand them, the better you can prepare, score, and enjoy the round.

Understanding course rating and slope rating isn’t about becoming a rules nerd or showing off in the clubhouse. It’s about managing your game and setting realistic expectations. So next time you’re scanning the card before the first tee, don’t just look at the yardage—look at what those numbers actually mean. They might just help you play smarter, lower your scores, and tell you how far you’ve come from the work you’ve been putting in. 

Plus, these metrics can help you make smarter decisions before you tee it up. If you know the slope is high and your game hasn’t been sharp, maybe move up a tee box or spend extra time on course management. If the course rating is low, it might be a good day to chase a personal best.
