About the Golf Handicap Calculator
This golf handicap calculator computes your handicap index using the World Handicap System (WHS) — adopted by the USGA, R&A, and all major golf associations in 2020 — from your recent score differentials. Enter up to 20 recent rounds (score, course rating, and slope rating) to see your handicap index calculated by averaging the best 8 of your last 20 differentials. Built for recreational golfers tracking their handicap, tournament players verifying their index, and golf coaches monitoring player progress.
