Formula: Course Handicap = Handicap Index x (Slope Rating / 113) + (Course Rating - Par)
Worked example — Course Handicap: 17 | Playing Handicap: 16
Formula
Course Handicap = Handicap Index x (Slope Rating / 113) + (Course Rating - Par)
Where Handicap Index is your portable measure of playing ability, Slope Rating measures course difficulty for bogey golfers relative to scratch golfers (standard 113), Course Rating is the expected score for a scratch golfer, and Par is the designed number of strokes.
Worked Examples
Example 1: Standard Course Handicap Calculation
Problem:A golfer with a 15.4 handicap index plays a course with slope 128, course rating 71.2, and par 72.
Solution:Course Handicap = 15.4 x (128 / 113) + (71.2 - 72) = 16.64. Rounded = 17 strokes. Playing Handicap (95%) = 16
Result:Course Handicap: 17 | Playing Handicap: 16
Example 2: High Slope Championship Course
Problem:A golfer with a 20.0 handicap index plays a championship course with slope 148, course rating 75.3, and par 72.
Solution:Course Handicap = 20.0 x (148 / 113) + (75.3 - 72) = 29.49. Rounded = 29. Playing Handicap (95%) = 28
Result:Course Handicap: 29 | Playing Handicap: 28
Frequently Asked Questions
What is a course handicap and how is it calculated?
A course handicap is the number of strokes a golfer receives on a specific course, adjusted from their handicap index based on the difficulty of that course. Under the World Handicap System (WHS), the formula is Course Handicap equals Handicap Index multiplied by Slope Rating divided by 113, plus the difference between Course Rating and Par. The standard slope rating of 113 represents a course of average difficulty. A course with a slope above 113 is more challenging and gives you more strokes, while a course below 113 is easier and gives fewer strokes. This ensures fair competition regardless of which course you play on.
What is the difference between handicap index and course handicap?
Your handicap index is a portable number that represents your overall playing ability, calculated from your best score differentials across multiple rounds. It stays the same regardless of where you play. Your course handicap, on the other hand, changes for every course and set of tees you play from. A player with a 15.0 handicap index might receive 13 strokes on an easy course with a low slope rating, but 18 strokes on a difficult course with a high slope rating. The course handicap translates your ability into the specific number of strokes needed to play a particular course at net par.
What is slope rating and why does it matter for course handicap?
Slope rating measures the relative difficulty of a golf course for a bogey golfer compared to a scratch golfer. It ranges from 55 to 155, with 113 being the standard neutral value. A high slope rating like 145 means the course is significantly harder for higher-handicap players relative to scratch golfers, so those players receive more strokes. A low slope like 90 means the course plays relatively easier for all skill levels. Slope matters because it directly scales your handicap index up or down, ensuring that the strokes you receive accurately reflect how much harder or easier a specific course will be for your skill level.
What is the difference between course rating and par?
Course rating is the expected score for a scratch golfer on a specific course, determined by official raters who evaluate factors like distance, obstacles, elevation changes, and green difficulty. Par is simply the designed number of strokes for each hole based on its length. A course might have a par of 72 but a course rating of 73.5, meaning even scratch golfers are expected to shoot 1.5 over par on average. The WHS formula adds the Course Rating minus Par adjustment to your course handicap, accounting for courses that play harder or easier than their par suggests. This adjustment can add or subtract strokes from your allowance.
What is a playing handicap and how does it differ from course handicap?
A playing handicap is the final number of strokes you actually receive in a competition, derived from your course handicap by applying a handicap allowance percentage. For individual stroke play, the allowance is 95 percent of your course handicap. For individual match play, it is 100 percent. For four-ball stroke play, the allowance is 85 percent, and for foursomes it is 50 percent of the combined handicap. So if your course handicap is 20, your playing handicap for stroke play would be 19. These allowances are set by the governing bodies to ensure equitable competition across different formats of play.
How do I know which holes I get strokes on?
Strokes are allocated based on the stroke index printed on the scorecard for each hole. Holes are ranked from 1 to 18 based on difficulty, with stroke index 1 being the hardest hole and 18 the easiest. If your course handicap is 14, you receive one extra stroke on the 14 holes with stroke indices 1 through 14. If your handicap exceeds 18, you get two strokes on the hardest holes and one on the rest. For example, a 22 course handicap means two strokes on holes with stroke indices 1 through 4 and one stroke on all remaining holes. Always check the scorecard for the specific allocation order.
Can my course handicap be higher than my handicap index?
Yes, absolutely. When you play a course with a slope rating above the standard 113, your course handicap will be higher than your handicap index. For example, a player with a 12.0 handicap index playing a course with a 140 slope rating would receive a course handicap of about 14.9, plus any Course Rating minus Par adjustment. Additionally, if the course rating is significantly above par, the CR minus Par adjustment adds even more strokes. On particularly difficult courses with both high slope and high course rating, you could receive several strokes more than your index. This system properly accounts for course difficulty.
How does the World Handicap System handle different tee boxes?
Each set of tees on a golf course has its own course rating and slope rating, reflecting the different distances and challenges presented. When calculating your course handicap, you use the ratings for the specific tees you are playing from. Forward tees typically have lower course ratings and often lower slope ratings, while back tees have higher values. This means a player might have a course handicap of 16 from the white tees but 19 from the championship tees at the same course. The WHS ensures fair competition even when players in the same group play from different tees by adjusting handicaps accordingly.
What happens if my course handicap is a negative number?
A negative course handicap means you are expected to score below par on that course. This typically only applies to very skilled plus-handicap golfers with a handicap index below zero. In competition, a player with a negative course handicap effectively gives strokes to the course rather than receiving them. For example, a plus-3 course handicap means the player must beat par by 3 strokes just to play to their handicap. In match play against a higher-handicap opponent, the plus-handicap player gives strokes based on the difference between the two course handicaps. These situations are relatively rare and mostly occur among elite amateur golfers.
Why was the CR minus Par adjustment added to the course handicap formula?
Before the World Handicap System was introduced in 2020, some handicap systems did not include the CR minus Par adjustment, which created inequities. Consider two courses both with par 72 where Course A has a course rating of 72.0 and Course B has a rating of 74.5. Without the adjustment, a 15-handicap player would get the same strokes on both, even though Course B plays 2.5 strokes harder for scratch golfers. Adding CR minus Par corrects this by giving about 2 to 3 extra strokes at Course B. This ensures that the handicap system accounts for courses rated significantly above or below par, producing fairer net scores.
