GHIN Differential Formula:
| From: | To: |
The GHIN (Golf Handicap Information Network) Score Differential is a measure of a golfer's performance relative to the difficulty of the course. It's used to calculate and maintain golf handicaps, allowing players of different skill levels to compete fairly.
The calculator uses the GHIN differential formula:
Where:
Explanation: The formula adjusts your raw score based on course difficulty, with Slope Rating indicating how much more difficult the course plays for average golfers compared to scratch golfers.
Details: Score differentials are crucial for maintaining an accurate handicap index. They allow for fair competition across different courses and conditions by normalizing scores based on course difficulty.
Tips: Enter your actual score, the course rating (typically between 67-77), and the slope rating (typically between 55-155). All values must be valid positive numbers.
Q1: What is a good differential score?
A: Lower differentials indicate better performance. A differential of 0 would mean you played to exactly scratch level for that course.
Q2: How many differentials are used for handicap calculation?
A: Typically, the best 8 of your most recent 20 differentials are used to calculate your handicap index.
Q3: What's the difference between Course Rating and Slope Rating?
A: Course Rating measures difficulty for scratch golfers, while Slope Rating measures relative difficulty for bogey golfers compared to scratch golfers.
Q4: Why is 113 used in the formula?
A: 113 is the standard slope rating, representing a course of average difficulty. The formula adjusts based on how much more or less difficult your course is compared to average.
Q5: How often should I post scores for handicap purposes?
A: You should post every acceptable score as soon as possible after completing your round, ideally within 24 hours.
