I have been a golf enthusiast for many years and I built this calculator to help easily calculate your golf handicap index.
Understanding the Golf Handicap Index Calculator
The handicap index calculator helps golfers determine their playing potential across different courses. Your handicap index is a more portable measure than a course handicap, as it can be used at any golf course worldwide.
What is a Handicap Index?
A handicap index represents your potential scoring ability on a course of standard difficulty. Unlike a course handicap, which is specific to one course, your handicap index can be used to calculate your course handicap at any golf course.
Key Components for Handicap Index Calculation
- Score differentials from your scoring record
- Course rating for each played round
- Slope rating from each course
- Playing conditions calculation (PCC)
Calculator Input Fields
Course Information
- Course Rating: The expected scores for a scratch golfer
- Slope Rating: The relative difficulty rating (113 is standard)
Round Information
- 18-hole scores: Complete round scores
- 9-hole scores: Partial round scores
- PCC: Playing conditions calculation adjustment
Calculation Process
Score Differential Calculation
(Score - Course Rating) × (113 ÷ Slope Rating) + PCC
This formula converts your scores into score differentials that account for course difficulty.
Handicap Index Determination
- Calculate score differentials for each round
- Sort differentials from lowest to highest
- Use the best 8 out of your last 20 score differentials
- Average the selected differentials
- Round to the nearest tenth
