Understanding 9-Hole Golf Handicap Calculation
A 9-hole handicap index is calculated using your adjusted gross scores from 9-hole rounds, along with the course rating and slope rating of the courses played. This calculation helps players of different skill levels compete fairly.
How to Use This Calculator
Follow these steps to calculate your 9-hole handicap:
- Enter your 9-hole score from your most recent round
- Input the course rating and slope rating for the 9 holes you played
- Add additional scores if available (more scores provide a more accurate handicap)
- Choose your calculation method (all scores, best 3, or most recent 3)
- Click "Calculate Handicap" to see your 9-hole handicap index
Understanding Course Rating and Slope
Course Rating
Course rating represents the expected score for a scratch golfer (0 handicap) on 9 holes. For example:
- A course rating of 35.5 means a scratch golfer should shoot around 35-36
- Lower ratings indicate an easier course
- Higher ratings indicate a more challenging course
- Most 9-hole course ratings range from 32 to 37
Slope Rating
Slope rating measures the relative difficulty of a course for bogey golfers compared to scratch golfers:
- The standard slope rating is 113
- Ratings range from 55 to 155
- Higher slopes indicate a greater difference in difficulty between scratch and bogey golfers
- Lower slopes indicate the course plays similarly for players of different skill levels
The Calculation Process
Step 1: Calculate Score Differential
For each round, the score differential is calculated using this formula:
Differential = (Score - Course Rating) × 113 ÷ Slope Rating
Step 2: Select Differentials
Based on your selection:
- All Available Scores: Uses all entered differentials
- Best 3 Differentials: Uses your three lowest differentials
- Most Recent 3: Uses your three most recent differentials
Step 3: Calculate Handicap Index
The final calculation:
- Average the selected differentials
- Multiply by 0.96 (the handicap adjustment factor)
- Round to the nearest tenth
When to Use 9-Hole Handicaps

Frequently Asked Questions
How many 9-hole scores do I need for a handicap?
You can calculate a handicap with as few as three 9-hole scores, but more scores (up to 20) will provide a more accurate handicap index.
How often should I update my handicap?
Update your handicap after each round played. Most handicap systems update daily with new scores.
Can I combine 9-hole and 18-hole scores?
Yes, two 9-hole scores can be combined to create an 18-hole score for handicap purposes. Use separate calculators for 9-hole and 18-hole rounds.
Where do I find course and slope ratings?
Course and slope ratings are typically displayed on:
- Scorecards
- Course websites
- Golf club notice boards
