Golf HCP Calculator (WHS Style)
Use this free calculator to estimate your Course Handicap and Playing Handicap for a round.
Common allowances: 100% stroke play, 95% individual match play, 85% four-ball.
What is an HCP in golf?
In golf, HCP usually means handicap. A handicap lets players of different ability levels compete fairly. Under the World Handicap System (WHS), your Handicap Index travels with you, while your Course Handicap adjusts for the specific course and tees you are playing.
This page focuses on the practical round-day numbers most golfers need: how many strokes you receive today, on this course, from these tees.
How this HCP calculator works
1) Course Handicap
We calculate Course Handicap with this standard formula:
Course Handicap = Handicap Index × (Slope Rating ÷ 113) + (Course Rating − Par)
The result is then rounded to the nearest whole number.
2) Playing Handicap
Competition formats may apply a handicap allowance. We calculate:
Playing Handicap = Course Handicap × (Allowance % ÷ 100)
That value is also rounded to the nearest whole number.
Input guide
- Handicap Index: Your official index from your golf association app or club system.
- Slope Rating: Difficulty for a bogey golfer, usually printed on the scorecard.
- Course Rating: Expected score for a scratch golfer on those tees.
- Par: Total par for the course from the selected tees.
- Allowance: Percentage of handicap used in your format (e.g., 95%).
Example calculation
Suppose your Handicap Index is 12.4, Slope Rating is 127, Course Rating is 71.8, Par is 72, and allowance is 95%.
- Course Handicap = 12.4 × (127 ÷ 113) + (71.8 − 72)
- Course Handicap = 13.73 → rounds to 14
- Playing Handicap = 14 × 0.95 = 13.3 → rounds to 13
In this example, you would receive 13 strokes in that 95% format.
Tips for accurate handicap planning
Check the correct tees
Slope and course rating change by tee box. Always use the values for the exact tees you are playing.
Know your format before the round
Match play, stroke play, team events, and four-ball can all use different allowance percentages. Confirm the rules with your competition committee.
Use official systems for posting scores
This tool is excellent for planning and understanding your numbers, but official handicap records should always come from authorized golf association platforms.
Quick FAQ
Is Handicap Index the same as Course Handicap?
No. Handicap Index is your portable ability measure; Course Handicap is specific to one course and tee set.
Why does Par matter in this formula?
WHS includes a course rating minus par adjustment so strokes reflect tee-specific scoring expectations more accurately.
Can this replace my club’s official handicap software?
No. This is an educational and planning tool. Use official systems for posted rounds and formal results.
