Slope Rating measures how much harder a course plays for a bogey golfer than for a scratch golfer. It equals 5.381 times the gap between Bogey Rating and Course Rating for men, or 4.240 times it for women. A men's tee rated 72.5 with a bogey rating of 96.7 has a gap of 24.2 strokes, so its slope is 130.

About this tool

Club handicap committees, golf society organisers and curious players use this to see where a printed Slope Rating comes from, or to estimate one for a set of tees that only lists its Course Rating and Bogey Rating. Pick men's or women's ratings, enter both ratings, and the result shows the slope, how far it sits from the standard 113, and a plain difficulty label on a 55 to 155 scale. Add your Handicap Index and the par of the tees to see the course handicap you would play off under the World Handicap System. The figure is only as good as the ratings you enter: official ratings come from trained teams measuring effective playing length and obstacles on site, and this calculation cannot replace that survey.

How to use it

  1. Choose the rating set

    Select men's or women's ratings; the multiplier changes from 5.381 to 4.240.

  2. Enter both ratings

    Type the Course Rating and Bogey Rating from the scorecard or rating sheet for one set of tees.

  3. Add your index if you like

    Fill in Handicap Index and par to get a course handicap for those tees.

  4. Read the scale

    The chart places the slope against easier, average, hard and very hard bands.

Examples

Men's tees, 72.0 / 93.0

Ratings for
Men (factor 5.381)
Course Rating
72
Bogey Rating
93

Result Slope Rating: 113
Difficulty for a bogey golfer: Around average difficulty
Bogey minus Course Rating: 21
Points above standard 113: 0
Course handicap: —

  1. Rating gap = 93 − 72 = 21
  2. Slope = 5.381 × 21 = 113 → 113

A bogey rating 21 strokes above the course rating gives exactly the standard Slope Rating of 113.

Women's tees, 73.0 / 99.6

Ratings for
Women (factor 4.240)
Course Rating
73
Bogey Rating
99.6

Result Slope Rating: 113
Difficulty for a bogey golfer: Around average difficulty
Bogey minus Course Rating: 26.6
Points above standard 113: 0
Course handicap: —

  1. Rating gap = 99.6 − 73 = 26.6
  2. Slope = 4.24 × 26.6 = 112.78 → 113

Women's ratings use the 4.240 factor, so a wider 26.6-stroke gap is needed to reach 113.

Back tees, 10.0 index

Ratings for
Men (factor 5.381)
Course Rating
72.5
Bogey Rating
96.7
Handicap Index
10
Par
72

Result Slope Rating: 130
Difficulty for a bogey golfer: Harder than average
Bogey minus Course Rating: 24.2
Points above standard 113: 17
Course handicap: 12

  1. Rating gap = 96.7 − 72.5 = 24.2
  2. Slope = 5.381 × 24.2 = 130.22 → 130
  3. Course handicap = 10 × 130 ÷ 113 + (72.5 − 72) = 12 → 12

5.381 × 24.2 gives a slope of 130, and a 10.0 index plays to a course handicap of 12 here.

How it is calculated

Slope = round(F × (BR − CR)), held between 55 and 155; Course handicap = HI × Slope ÷ 113 + (CR − Par)

F
5.381 for men's ratings, 4.240 for women's
BR
Bogey Rating, the expected score of a bogey golfer
CR
Course Rating, the expected score of a scratch golfer
HI
Handicap Index

The USGA Course Rating System defines slope as the rate at which scores climb as ability drops. The multiplier scales the scratch-to-bogey gap so that an average course lands on 113; the women's factor is smaller because the reference bogey golfer for women has a higher handicap. Results are rounded to a whole number and limited to the official 55 to 155 range. The course handicap follows the World Handicap System formula and is rounded to the nearest whole stroke.

When not to use it

  • Do not post scores against a slope you estimated here; use the rating the authorised association published.
  • It cannot rate a course from yardage alone, because Bogey Rating needs an on-site obstacle survey.
  • It does not compute playing handicap allowances for team formats such as four-ball.

Common mistakes

  • Mixing a men's Course Rating with a women's Bogey Rating from the same tees.
  • Entering par in place of the Course Rating; the two often differ by a stroke or more.
  • Expecting a high slope to mean a hard course for scratch players, when it measures the bogey golfer's extra difficulty.

Frequently asked questions

Why is 113 called the standard slope?

The system was calibrated so that a course of average relative difficulty gets 113. A Handicap Index is defined for that standard course, which is why the course handicap formula divides by 113.

What range can a Slope Rating take?

Official slopes run from 55 to 155. Most championship and resort tees fall between about 115 and 145, while short or open parkland tees often sit between 100 and 120.

Why do men and women use different multipliers?

The reference bogey golfer is defined with a Handicap Index of about 20 for men and 24 for women. That larger spread for women means each stroke of rating gap counts for less slope, so the factor is 4.240 rather than 5.381.

Can two courses with the same Course Rating have different slopes?

Yes. Two tees rated 71.0 for a scratch player can differ a lot for a bogey player if one has forced carries, narrow fairways or heavy rough that punish missed shots. That difference shows up only in the Bogey Rating and therefore in the slope.

How does slope change my course handicap?

Your index is multiplied by slope over 113. A 10.0 index becomes about 11.5 on a 130 slope and about 8.8 on a 100 slope, before the Course Rating minus par adjustment is added.

Where do I find the Bogey Rating?

It is rarely printed on scorecards. National associations and some club rating sheets list it next to the Course Rating; if you only have Course Rating and slope, you can work it back as CR plus slope divided by the factor.
