Golf handicap calculator
Course Handicap and Playing Handicap for one player or a full group, with the official WHS formula.
Indicative result. Your official handicap is issued by your home club or national federation.
Formula
Course Handicap = Handicap Index × (Slope / 113) + (Course Rating − Par)
Playing Handicap = Course Handicap (unrounded) × format allowance
Where to find Course Rating, Slope and par
These three numbers describe the difficulty of a course from a specific set of tees. They are printed on every scorecard and listed on the course's official handicap form. Each tee box has its own values.
- Course Rating — the score a scratch golfer (HCPI 0) is expected to shoot, to one decimal place. Typically 65–76.
- Slope Rating — a measure of relative difficulty for a bogey golfer compared to a scratch golfer. Range 55–155, standard value 113.
- Par — the standard score for the course, usually 70–72 over 18 holes.
Outside Finland, your national federation publishes course rating files alongside the scorecards. The R&A also hosts an official course handicap calculator for reference values.
