गोल्फ़ हैंडीकैप कैलकुलेटर (WHS).

Unofficial: caps, exceptional-score reductions and 9-hole rounds are not applied. Everything is calculated in your browser; nothing you type is uploaded.

Differential = (113 ÷ slope) × (score − rating − PCC); the index averages the lowest differentials from the WHS table.

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.
