Calculate your golf handicap index using the official USGA formula. Understand your skill level, track your progress, and compete fairly with golfers of all abilities!
Your handicap index represents your potential playing ability. The lower your handicap, the better golfer you are. A handicap of 0 is a "scratch golfer" who typically shoots par.

The USGA Handicap System is designed to measure a golfer's potential ability and enable players of different skill levels to compete equitably. Here's the detailed explanation:
Course Rating: Represents the expected score for a scratch golfer (handicap 0) on a course under normal conditions. It's based on yardage and other obstacles.
Slope Rating: Measures the relative difficulty of a course for bogey golfers compared to scratch golfers. It ranges from 55 to 155, with 113 being the standard difficulty.
Handicap Formula: (Score - Course Rating) × 113 ÷ Slope Rating. This calculation produces a Handicap Index that represents a player's potential ability.
An official USGA Handicap Index requires a minimum of 54 holes (typically three 18-hole rounds) and is calculated using the best 8 of the most recent 20 scores.

Frequently Asked Questions
What is a golf handicap and why is it important?
A golf handicap is a numerical measure of a golfer's potential ability that allows players of different skill levels to compete fairly. It represents the number of strokes above par a player is expected to shoot on a course of standard difficulty. The handicap system enables golfers of all abilities to enjoy competitive play together by adjusting scores based on each player's skill level. This creates a more equitable playing field and makes the game enjoyable for everyone regardless of their experience or natural ability.
How accurate is this golf handicap calculator?
This calculator uses the official USGA (United States Golf Association) formula for calculating a handicap index: (Score - Course Rating) × 113 / Slope Rating. While this provides an accurate single-round handicap estimate, an official USGA handicap requires multiple scores (typically 20 rounds) to establish a reliable index that reflects a player's true potential ability. The official system uses the best 8 scores from the most recent 20 rounds, making it more representative of a golfer's potential rather than their average performance.
What's the difference between Course Rating and Slope Rating?
Course Rating measures the difficulty of a course for a scratch golfer (handicap 0) and represents the expected score for that player. It's typically between 67 and 77 for 18 holes. Slope Rating measures the relative difficulty of a course for a bogey golfer compared to a scratch golfer, with higher numbers indicating more difficulty for average players. Slope Rating ranges from 55 to 155, with 113 being the standard difficulty. While Course Rating indicates overall difficulty, Slope Rating shows how much more challenging the course is for higher-handicap players.
