How to Calculate Slope Rating
The slope rating of a golf course is a measure of its difficulty for bogey golfers. The term comes from the likelihood that when playing on more difficult courses, players’ scores will rise more quickly than their handicaps would predict. The “slope rating” of a course thus predicts that rise.
Q. What is a Slope Rating® and what does it represent? A. Playing length and obstacles impact higher-handicap players more than lower-handicap players, and Slope Rating measures the relative difficulty of a golf course for players who are not scratch players compared to those who are scratch players.
The higher the slope number, the harder the course is for the bogey golfer relative to the difficulty of the course for the scratch golfer. Slope numbers can range anywhere between 55 and 155 with the average slope in the United States being 120.
If you see a slope rating that falls anywhere in the double digits, you can expect that course to play rather easy, even for a bogey golfer. On the other hand, taking on a course with a slope rating in the 130's or 140's is going to present a serious challenge to a player with a mid or high handicap.
Slope rating (a term trademarked by the United States Golf Association) is a measurement of the difficulty of a golf course for bogey golfers relative to the course rating. Course rating tells scratch golfers how difficult the golf course will be; slope rating tells bogey golfers how difficult it will be.
Slope merely tells you how “proportionately” more difficult that particular set of tees plays for the higher handicapped golfers as opposed to lower handicapped golfers. The more difficult the tees play proportionately for the higher handicappers, the greater the Slope rating that will be issued. That's it!

What Is A Good Golf Handicap? A good golf handicap is ten or less. With a handicap index of ten or less, you will generally shoot somewhere around 82. Shooing in the low 80s is better than average but certainly not good enough to be considered a scratch player.
The middle tees are for middle to high handicap men, low-handicap or long-hitting women, and low-handicap or long-hitting senior men. The forward tees are for middle or high handicap women and seniors, and beginners of all stripes.
1. The average handicap index for men is 14.2. 2. The average handicap index for women is 27.5.
Handicap differential = (Adjusted Gross Score-rating of the course) X 113 / Course slope ratings. The course rating is simply the scores of a new golfer on a normal course under a normal playing condition. Slope rating is the rating of 113 for a course based on the standard difficulty.
What is a hard slope rating? If we know that the average slope rating of a golf course is 113, we can deduce that any golf course with a slope rating higher than 113 is more difficult than the average course. Don't be intimidated if you see a slope rating that is above 113.
A bogey is typically considered to be a fairly bad score on a golf hole, as it is a single stroke above par. However, less experienced golfers may view a bogey as an average score since shooting par is not always an easy task. Bogeys are better than double bogeys, triple bogeys, quadruple bogeys.
Well this is all well and good, but how is this number calculated? Well technically, the number represents how much more difficult a given set of tees is for a bogey player in relation to scratch handicapper. You might think that this difference is fairly constant, but that isn’t the case at all. As a course becomes more difficult, a bogey player’s score will rise far more quickly than our scratch player. Although both will struggle horribly around Bethpage black or St Andrew’s, the bogey player’s numbers would be off the scales big.
This gives you an adjusted yardage based on the difference in elevation between where you are and where you want to go by using some fancy tech to essentially give an angle up or down which is used to adjust the distance. once you have the angle, the new distance is really little more than basic maths using right-angled triangles.
This slope rating is a number, which can go from 55 all the way up to 155. The average course will sit around 110-115. This number also varies depending on which set of tees you play off. For example, my home course has a rating of 136 if I play off the white tees (it is quite a tricky course) and 127 off the yellows. This means that as a 9 handicap golfer, I will get something like 12/13 shots from the whites and about 9 from the yellows.
As a course becomes progressively more difficult, the difference between bogey and scratch becomes larger and the slop increases in a general upwards trend (hence, slope.)
A slope number simply allows you to know, at least to some extent, what the difference really is. It allows you to pick the right set of tees depending on your length and handicap and have a better chance of actually enjoying yourself on the course.
Slope is also used to mean something completely different. Confusing, right? Slope is part of a variable when calculating distance as I explained in another article.
The most important role of a slope is leveling the playing field for players of different skill levels. For example, let's say Player A and Player B average 85 strokes each for 18 holes. But Player A's average is established on a very difficult course (say, a slope rating of 150), while Player B's average is established on a much easier course (say, a slope rating of 105). If handicaps were simply estimates of golfers' average scores, then these two players would have the same handicap index. But Player A is clearly the better golfer, and in a match between the two Player B would clearly need some strokes.
Slope rating (a term trademarked by the United States Golf Association) is a measurement of the difficulty of a golf course for bogey golfers relative to the course rating.
To put it another way: USGA Course Rating tells the best golfers how hard a golf course actually plays; USGA Slope Rating indicates how much harder the course plays for "regular" (meaning not among the best) golfers.
The minimum slope rating is 55 and the maximum is 155 (slope does not relate specifically to strokes played as course rating does). When the slope rating system was first put into effect, the USGA set the slope for an "average" golf course at 113; however, not many 18-hole golf courses have slope ratings that low.
The slope is primarily used in the United States, but golf associations in other countries are beginning to adopt slope or similar systems.
Because he plays on a course with a higher slope rating, Player A's handicap index will be lower than Player B's (when it is calculated using the slope ratings), despite the fact that they both average scores of 85. So when A and B get together to play, B will get those extra strokes he needs.

The minimum slope rating is 55 and the maximum is 155 (slope does not relate specifically to strokes played as course rating does). The higher the slope, the more difficult the course is. When the slope rating system was first put into effect, the USGA set the slope for an "average" golf course at 113; however, not many 18-hole golf courses have slope ratings that low. Some do, but the real-world average is higher than 113. (However, a slope of 113 is still used in certain calculations within the handicap system.)
USGA Course Rating is an evaluation of the difficulty of a golf course for scratch golfers. (More specifically, the number is an estimate of the average scores of the best 50-percent of rounds played by scratch golfers at the course being rated.) Course rating is very easy to understand because it is expressed in strokes.
The golf course slope is a measure of a course's difficulty, but it is not considered the better of the two measurements. Golf course slope is actually derived from the golf course rating. Slope is a measure of a golf course's difficulty in a relative comparison of a scratch golfer to a bogey golfer (someone who shoots around 90 for 18 holes).
You calculate slope rating by finding the bogey rating, which is like the course rating, but measured for a bogey golfer. Then subtract the course rating from that figure. Then multiply that figure by 5.381 for men and 4.24 for women. Then round up to the nearest whole number.
A golf course rating tells you what a scratch golfer would be expected to shoot from the tees they're playing on a particular course under normal conditions. The rating is different for men and women.
A male scratch golfer, for rating purposes, can hit tee shots an average of 250 yards and can reach a 470-yard hole in two shots.". A scratch woman can "can hit tee shots an average of 210 yards and can reach a 400-yard hole in two shots at sea level.".
Course slope is a figure that indicates the difficulty of a course in relation to a golfer who averages a bogey on every hole, and therefore, averages 18-over par on any given round.
Handicap is a number assigned to a golfer, indicating the number of strokes over par they are on an average round of golf. For instance, a golfer with an 18 handicap would typically shoot 18-over par during a round of 18 holes. On a course with a course rating of 72, this golfer would be expected to shoot 90. Meanwhile, a golfer with a 20 handicap would be expected to shoot 92 on this same course.
Course rating is a figure that indicates the difficulty of a golf course to a golfer who averages even par on a round of 18. For instance, a course rating of 72 would portend that a "scratch golfer" would shoot 72 on that particular course.
Course and slope rating can impact final scores in scramble tournament play.
The slope values can range anywhere from 55 to 155. The average golf course is 113. This may seem like an odd number for a bogey golfer to have to remember and base their golf round off of. The United States Golf Association came up with these systems, and they work pretty well, but there is undoubtedly a learning curve involved.
The handicap system allows bogey golfers to have a fair match against scratch golfers, which makes golf such a special and vital sport.
A golf course rating is a number that tells you what a scratch golfer should be shooting at that golf course. Scratch golfers are known for their ability to shoot par on a golf course. However, not all golf courses are made to be the same difficult.
If a scratch golfer plays this course and shoots a 74, the player’s handicap differential would still be zero. Therefore the golfer’s handicap index is not going to be adjusted or changed all that much because they were playing a more challenging golf course.
A higher golf course rating means that the course raters have decided that it is much harder for a scratch golfer to shoot par at the golf course. Chances are the course rating is closer to 74 or even 75, and therefore that is what a typical scratch player would shoot.
The handicap index is created by calculating an average of 20 score differentials of a player. The score differential is the difference between your adjusted gross score and the course rating. Therefore if you are a golfer that shot 90 on a course with a 72.5 rating, your score differential would be 17.5.
Golf course handicaps will update every two weeks or so. If you all of a sudden have an increase in your handicap, yet you have been playing great golf, don’t forget to consider that it has to do with the golf courses that you have been playing.
Course slope or Golf Slope is a figure that indicates the difficulty of every hole in relation to an average golfer who scores one bogey on each course. For instance, if you're playing golf at a 90-degree angle with slopes and greens so flat it might as well be desert terrain--then your score would reflect this by being closer towards 150 than 18 holes.
A golf course's slope rating is a mathematical measure of the difficulty for any golfer. The USGA par and expected score will be subtracted from each other, then multiplied by 5381 to determine what type of player should play on this particular day if they are looking at getting an accurate number out-of-the-box (and don't know their own).
There are two different types of golf variations present in a golf course
This is because it tells you what kind of player a given course will challenge, and whether or not they should bring their best game if they're playing that particular layout.
