Golf Handicap Index Calculator
Work out your golf handicap index from your recent score differentials using the World Handicap System. Under the current rules your index is the average of your best differentials from your most recent rounds, then multiplied by 0.96. This tool applies the sliding scale automatically: with fewer than twenty scores it uses the correct number of lowest differentials and any built in adjustment, and with twenty scores it averages your best eight. A score differential comes from your adjusted gross score, the course rating and the slope rating for the tees you played. Paste one differential per line, and the calculator sorts them, picks the right count, averages them and rounds to one decimal place. Everything runs in your browser, so your scoring history stays private and nothing is uploaded to a server.
