Golf Handicap Calculation:

A golfer's handicap is calculated by averaging the lowest 10 handicap differentials from the 20 most recent postings in a golfer's scoring record.

Each round is given a Handicap Differential by the following calculation:

Handicap Differential = (Adjusted Gross Score - Course Rating) * (113 / Slope Rating)

The above calculator only estimates your Handicap based on your 3 best rounds in recent memory.
