Golf Handicap Calculator
Calculate score differentials for a dated 3-to-20-score record, apply the WHS selection table, exceptional-score reductions, and soft or hard cap against the entered Low Handicap Index.
How to use the Golf Handicap Calculator
Enter matching scores, ratings, slopes, PCC values, ordered dates, Handicap Index values in effect, and the preceding 365-day Low Handicap Index.
Review current WHS rules, acceptable scores, course and tee data, PCC, exceptional-score reductions, caps, playing conditions, and authorized record history.
Read score differentials, lowest differentials used, exceptional scores detected, cap applied, and the basic Handicap Index estimate.
Formula
Score differential = (113 ÷ slope rating) × (adjusted gross score − course rating − PCC). The Handicap Index uses the prescribed number of lowest differentials, adjustments, and rounding for the record size.
Example
An adjusted score of 90 on a 72.0/120 course with PCC 0 gives differential (113 ÷ 120) × 18 = 16.95 before prescribed rounding.
Assumptions and limitations
- The result depends on accurate official course data and a complete acceptable-score record; only an authorized association issues an official Handicap Index.
- Golf Handicap Calculator treats the entered values as estimates and does not infer missing project, account, or personal details.
- Calculations retain working precision except where the cited method requires an intermediate rounding step; displayed values are then formatted separately. Source rules and dated rates must be rechecked when they change.
