Golf Handicap Calculator & Score Chart
Wondering what handicap is shooting 90 — or 80, or 100? Calculate a round's differential for any course below, then jump to a detailed breakdown for your exact score.
Your Handicap Index is the average of your best 8 differentials from your last 20 rounds, multiplied by 0.96 — so a single round's differential is a snapshot, not your index. Slope 113 and rating 72.0 represent a course of standard difficulty.
How a golf handicap works
A Handicap Indexis a portable number representing your ability, so players of any level can compete fairly. Under the World Handicap System it's the average of your best 8 Score Differentials from your last 20 rounds, multiplied by 0.96. Because it uses your better rounds, your index sits a few strokes below your typical score — a golfer who averages 90 usually carries an index around 14–16, not 18.
At any given course, your index converts to a Course Handicapusing that course's Slope Rating, which is why the same index gives you more strokes at a harder course.
