WHS Explained

Playing Handicap vs
Course Handicap.

Under the WHS, every golfer has a Handicap Index — but you need two more numbers before you tee off. Here's what Course Handicap and Playing Handicap are, how they differ, and how to calculate both.

Step 1 — Course Handicap

Formula

Course Handicap = HI × (Slope ÷ 113) + (Course Rating − Par)

Your Course Handicap takes your portable Handicap Index and adjusts it for the specific course and tees you're about to play. A harder course (high Slope Rating, CR above Par) gives you more shots. An easier course gives you fewer.

You calculate a new Course Handicap every time you play a different course or change tee. On most modern scorecards, it's printed in a table — look up your HI row and Slope column and the Course Handicap is shown. Or use the course handicap calculator.

Step 2 — Playing Handicap

Formula

Playing Handicap = Course Handicap × Allowance %

Your Playing Handicap is the actual number of shots you receive on your scorecard. The WHS applies a format-specific allowance percentage to your Course Handicap to get it. In singles matchplay, that allowance is 100% — your Playing Handicap equals your Course Handicap. In Stableford, it's 95%.

FormatAllowance
Individual Stableford95%
Stroke Play (medal)95%
Singles Matchplay100%
Four-Ball Better Ball85% per player
Foursomes50% of combined CH
Greensomes0.6 × lower + 0.4 × higher

Full worked example

Slope 126, Course Rating 73.2, Par 72

Player: Handicap Index 15.4

Step 1 — Course Handicap
15.4 × (126 ÷ 113)= 17.17
+ (73.2 − 72)= + 1.2
Total → roundedCourse Handicap = 18
Step 2 — Playing Handicap (Stableford)
18 × 0.95= 17.1
RoundedPlaying Handicap = 17
Step 2 (alternative) — Playing Handicap (Singles Matchplay)
18 × 1.00= 18
No rounding neededPlaying Handicap = 18
The same golfer receives 17 shots in Stableford but 18 shots in singles matchplay — because the format allowance changes.

Common questions

Which number goes on my scorecard — Course Handicap or Playing Handicap?

Your Playing Handicap goes on your scorecard — it's the actual shots you receive. Course Handicap is an intermediate calculation. In practice for a 95% format like Stableford, some clubs write the Course Handicap on the card and apply 95% separately. For a 100% format like singles matchplay, Course Handicap = Playing Handicap, so there's no distinction.

Does my Handicap Index ever change within a round?

No. Your Handicap Index is fixed at the start of the competition and does not change mid-round, even if a new handicap review is triggered during play. Your Course Handicap and Playing Handicap for that round are locked in at the time the competition starts.

What's the difference between Handicap Index and Course Handicap?

Your Handicap Index is a portable, course-neutral measure of your ability — it's the same number wherever you play in the world. Your Course Handicap converts that Index into the number of shots appropriate for a specific course and tee set. Think of Handicap Index as your passport and Course Handicap as the local currency conversion when you arrive.
