How to use Golf Handicap Calculator (WHS)
Add up to 20 recent 18-hole rounds with the adjusted gross score, course rating, slope and PCC. Optionally enter the tees for your next round.
How it works
Differential = (113 ÷ slope) × (score − rating − PCC); the index averages the lowest differentials from the WHS table.
Example
Eight rounds use the best 2 differentials (16.0 and 15.1) for a Handicap Index of 15.6; on a 128 slope course rated 71.2 at par 72 that is a course handicap of 17.
