Golf Handicap Calculator
Calculate your golf handicap index from recent round scores, course ratings and slope ratings.
What is Golf Handicap Calculator?
A golf handicap index is a standardized number that represents a golfer's potential playing ability, allowing players of different skill levels to compete fairly against each other. The lower the handicap, the better the player.
It is calculated from recent round scores adjusted by the difficulty of each course, which is captured by the course rating and slope rating. This calculator estimates your handicap index from your most recent rounds.
How does the Golf Handicap Calculator work?
Each round produces a score differential that normalizes your raw score for the course you played. The course rating is the expected score for a scratch golfer, and the slope rating measures the course's difficulty relative to a standard course.
The handicap index is the average of your differentials multiplied by 0.96. The 113 is the standard slope rating used as a baseline so all courses are compared on the same scale.

- Enter your score for each of your three most recent rounds.
- Enter the course rating and slope rating printed on the scorecard for each course.
- Review each round's score differential.
- Read your estimated handicap index at the top of the results.

Frequently Asked Questions
What is the 113 in the formula?
113 is the standard slope rating used as a baseline. Slope ratings around this value represent an average-difficulty course, and the formula normalizes your score to that baseline.
What does a lower handicap index mean?
A lower handicap index means you are a stronger player. A scratch golfer has a handicap near 0, while higher numbers indicate more room for improvement.
Why multiply the average by 0.96?
The 0.96 multiplier is the official convention in the handicap system. It makes the index slightly more conservative so it reflects a golfer's potential rather than an average score.
This calculator turns a tedious calculation into an instant answer, so you can focus on understanding the concept instead of the arithmetic.
