Golf Handicap Calculator

How golf handicap is calculated

The official USGA/World Handicap System averages your best score differentials from your last 20 rounds, with the exact number of rounds used depending on how many you've played. This calculator uses a simplified version based on the rounds you enter.

The formula

113 is the "standard" slope rating used as a baseline, and the 0.96 multiplier is applied by the official system as a slight downward adjustment.

How to use this calculator

1. Enter your score, the course rating, and the slope rating for each recent round (found on the scorecard or course website).
2. Enter 1-3 rounds — more rounds gives a more representative average.
3. Press Calculate to see your estimated handicap index.

Frequently asked questions

Is this an official USGA handicap? No — this is a simplified estimate for personal reference. An official World Handicap System index requires posting scores through an authorized golf association or club.

What's a course slope rating? Slope rating measures the relative difficulty of a course for a bogey golfer compared to a scratch golfer, ranging from 55 to 155, with 113 representing standard difficulty.

What's a good golf handicap? A single-digit handicap (0-9) is considered advanced, 10-18 is solid intermediate, and most recreational golfers fall somewhere between 15 and 25.

How many rounds does the official system use? The World Handicap System uses up to your best 8 of your last 20 scores, updated daily as you post new rounds — this calculator simplifies that to whatever rounds you enter here.
