About This Calculator
The Golf Handicap Calculator helps you estimate your golf handicap index based on your scores, course rating, and slope rating. A golf handicap allows players of different skill levels to compete fairly by adjusting scores based on course difficulty.
This tool is useful for golfers who want to track their handicap or estimate their playing ability. The calculator uses the standard USGA handicap formula, which considers your best scores relative to the course difficulty (rating and slope).
Formula & Calculation Method
Golf handicap is calculated using the following formulas:
- Score Differential: ((Score - Course Rating) × 113) / Slope Rating
- Handicap Index: Average of the best differentials (typically best 8 of 20 scores)
Where:
- Course Rating = Difficulty of the course for a scratch golfer (typically 68-74)
- Slope Rating = Relative difficulty for a bogey golfer compared to scratch golfer (typically 113)
- 113 = Standard slope rating (average difficulty)
Note: The official USGA handicap system uses the best 8 differentials from your most recent 20 scores. This calculator provides an estimate based on the scores you enter.

Frequently Asked Questions
What is a golf handicap?
A golf handicap is a numerical measure of a golfer's potential ability. It allows players of different skill levels to compete fairly by adjusting scores based on course difficulty. Lower handicaps indicate better players.
How is handicap index different from course handicap?
Handicap Index is a standardized measure of ability. Course Handicap is the number of strokes a player receives on a specific course, calculated as: Handicap Index × (Slope Rating / 113).
What is course rating and slope rating?
Course Rating is the difficulty of a course for a scratch golfer (par). Slope Rating measures the relative difficulty for a bogey golfer compared to a scratch golfer. Standard slope is 113.
How many scores do I need for an accurate handicap?
The USGA handicap system uses the best 8 differentials from your most recent 20 scores. However, you can get a reasonable estimate with as few as 3-5 scores, though more scores provide better accuracy.
