Turn your Handicap Index into the strokes you get on a specific course and set of tees. WHS-style math, 9-hole and plus handicaps supported.
Index × (Slope ÷ 113) + (Rating − Par)
Rounded to the nearest whole number. A harder course (higher slope or rating) gives you more strokes than an easier one.
Many formats apply an allowance, such as 95% for individual stroke play. The playing handicap is the unrounded course handicap times the allowance, rounded once at the end.
Halve your index, then use the 9-hole rating and par. Without a native 9-hole rating, we use half the 18-hole rating and half the par with the same slope.
A plus handicap, such as +2.1, belongs to a player who typically beats the course rating. Plus players give strokes back, so the result is shown with a plus sign.

Your Handicap Index measures your potential ability on a course of standard difficulty. Your course handicap converts that index into the strokes you receive on a specific course and set of tees.
Course Handicap = Handicap Index x (Slope Rating / 113) + (Course Rating - Par), rounded to the nearest whole number.
Halve your Handicap Index, then apply the same formula using the 9-hole course rating and par. If a tee has no 9-hole rating, this calculator uses half the 18-hole rating and half the par with the same slope.
A plus handicap, such as +2.1, belongs to a player who typically scores better than the course rating. Plus players give strokes back, so the course handicap is shown with a plus sign.
Some leagues run their own handicap method, cap indexes, or apply a different allowance. Use the allowance menu to match your format.

The calculator works off numbers you type in. LeaderBoard Caddie applies handicap strokes from each player's index and tees automatically, and keeps handicaps up to date every week.
