Enter your adjusted score, course rating, and slope rating into the calculator to determine your golf handicap index.

Golf Handicap Index Calculation Formula

The following formula is used to calculate the golf handicap index:

Handicap Index = (Adjusted Score - Course Rating) * 113 / Slope Rating

Variables:

  • Handicap Index is a measure of a golfer’s potential ability.
  • Adjusted Score is the score adjusted for course difficulty.
  • Course Rating is the expected score for a scratch golfer on a specific course.
  • Slope Rating is a measure of the difficulty of a course for a bogey golfer compared to a scratch golfer.

To calculate the handicap index, subtract the course rating from the adjusted score, multiply the result by 113, and then divide by the slope rating.

What is a Golf Handicap Index?

The golf handicap index is a numerical measure of a golfer’s potential ability based on their past performance. It allows players of different skill levels to compete fairly against one another. The lower the handicap index, the better the golfer is considered to be. The system is designed to level the playing field, enabling golfers of varying abilities to enjoy the game together.

FAQ

1. What is an adjusted score?

An adjusted score is the score a golfer achieves after accounting for the maximum number of strokes they can take on a hole, which is determined by the course’s par and the golfer’s skill level.

2. How is the course rating determined?

The course rating is determined by evaluating the difficulty of a golf course for a scratch golfer, taking into account factors such as length, obstacles, and overall course conditions.

3. What does slope rating mean?

Slope rating measures the difficulty of a golf course for a bogey golfer compared to a scratch golfer. A higher slope rating indicates a more challenging course for average players.

4. How often should I update my handicap index?

It’s recommended to update your handicap index after every round of golf you play, especially if you have a significant change in your performance or if you play on different courses.

5. Can I use this calculator for different courses?

Yes, you can use this calculator for any golf course by entering the appropriate course rating and slope rating for that specific course to calculate your handicap index accurately.
