Golf Handicap Calculator

Use it when your task matches one of these common needs: Estimate a round score differential from adjusted score, course rating, slope rating, and PCC. Estimate course handicap from Handicap Index, slope rating, course rating, and par. It works best when you already know the adjusted gross score, course rating, slope rating, PCC, Handicap Index, par, and allowance from the exact tees or format you are checking.

In plain language: Score differential uses (113 / slope rating) x (adjusted gross score - course rating - PCC). Course handicap uses Handicap Index x (slope / 113) + (course rating - par). The examples on the page are there so you can compare your inputs with a golf scorecard example before copying the answer.

Adjusted gross score: the round score after any maximum-hole-score adjustments required by the handicap rules. If you only know raw strokes, confirm the adjusted score first. Course rating: the expected score for a scratch player from the exact tees. Use the rating printed for your tee set, not a different box. Slope rating: the course difficulty number for non-scratch players. WHS-style formulas use 113 as the standard slope. PCC: the playing conditions calculation. Leave it at 0 unless your official scoring record or event gives a value. Handicap Index: your official index before it is adjusted for the course and tees you are playing. Allowance: the event or format percentage used to turn course handicap into playing handicap.

Read the headline answer, then check the smaller lines beside it. For everyday tools, those lines usually show the distance, time, cost, units, or setting that made the answer change.

This estimates one round or one tee setup. It does not create an official Handicap Index. Official records can include score-history rules, caps, exceptional-score reductions, 9-hole handling, and committee adjustments. Also check the exact tees, rating, slope, par, PCC, and allowance. A small tee or rating change can move the answer by a stroke.

No. It estimates score differential, course handicap, and playing handicap. An official Handicap Index needs your scoring record and the rules used by your golf association.

They adjust for the course and tees. An 86 from harder tees can be a better round than an 86 from easier tees, so the calculator needs those numbers.

Use 0 for a normal estimate. Enter -1, 1, 2, or 3 only when the official scoring record or event gives a playing conditions adjustment.

Course handicap is the tee-adjusted number. Playing handicap applies the allowance for the game format, such as 95% for some singles formats or 85% for some partner formats.

Use it as a check only. For an official event, use the tournament committee, GHIN or local association app, and the exact rules for that format.

No. The calculation runs in your browser tab. Your score, rating, slope, par, index, and allowance are not sent to a server.
