Knowing your handicap index is one thing. Knowing how to actually apply those strokes hole-by-hole on a scorecard is what lets you compete fairly with players of any skill level. Here is exactly how it works.
Your Course Handicap is calculated from your Handicap Index, the slope rating, and course rating for the specific tees. Check the scorecard header, the handicap calculator on the course website, or the USGA app. This is NOT the same as your Handicap Index.
Every scorecard has a Stroke Index column — sometimes labeled "HCP" or "Hdcp." It ranks the 18 holes from 1 (hardest) to 18 (easiest). This determines which holes you receive your strokes on, not the hole number.
You receive one stroke on every hole whose Stroke Index is less than or equal to your Course Handicap. Example: if your Course Handicap is 14, you get a stroke on holes rated SI 1 through SI 14. If your handicap is 19, you get one extra stroke on SI 1 (total two strokes on that hole).
For each hole where you receive a stroke, subtract 1 from your gross (actual) score to get your net score. If you made a 5 on a par-4 where you get a stroke, your net score is 4 (a net par).
In match play, only the difference in handicaps matters. The lower handicap player plays scratch; the higher handicap player receives the difference on the hardest stroke-index holes. Example: a 12 playing a 20 — the 20-handicap gets 8 strokes on SI 1 through SI 8.
An 18-handicap receives one stroke on every hole (all 18 SIs are 18 or below). Here is how their net score is calculated on the first 5 holes:
| Hole | SI | Par | Gross | Net | Explanation |
|---|---|---|---|---|---|
| 1 | 7 | 4 | 5 | 5 | 18 handicap gets a stroke only on SI 1-18; this is SI 7 so yes |
| 2 | 15 | 3 | 4 | 3 | SI 15 is within 18 — stroke received → 4 becomes net 3 (par) |
| 3 | 1 | 5 | 6 | 5 | Hardest hole (SI 1) — always gets a stroke, 6 becomes net 5 |
| 4 | 9 | 4 | 5 | 4 | SI 9 within 18 — stroke given, net 4 (par) |
| 5 | 3 | 4 | 5 | 4 | SI 3 — stroke received, 5 becomes net 4 |
| Match-up | Difference | Strokes given | Which holes |
|---|---|---|---|
| Player A (12 handicap) vs Player B (20 handicap) | 8 strokes | Player B gets 8 strokes | Holes rated SI 1 through SI 8 (the 8 hardest holes) |
| Player A (5 handicap) vs Player B (15 handicap) | 10 strokes | Player B gets 10 strokes | Holes rated SI 1 through SI 10 |
| Player A (0 handicap) vs Player B (18 handicap) | 18 strokes | Player B gets 18 strokes | Every hole (SI 1 through SI 18) |
| Player A (22 handicap) vs Player B (18 handicap) | 4 strokes | Player A gets 4 strokes | Holes rated SI 1 through SI 4 (hardest 4 holes) |
Stroke index is the ranking of each hole from 1 (hardest) to 18 (easiest) on a scorecard. It is used to determine which holes you receive handicap strokes on. Hole 1 on the scorecard might be SI 7, meaning it is the 7th hardest hole — you get a stroke there if your handicap is 7 or higher.
Find the Stroke Index column on your scorecard (may be labeled HCP or Hdcp). You receive one stroke on every hole whose Stroke Index number is less than or equal to your Course Handicap. If your Course Handicap is 12, you get strokes on the 12 holes rated SI 1 through SI 12.
Your gross score is your actual stroke count per hole. Your net score is the gross score minus any handicap strokes you receive on that hole. Net scores are used to compare players of different skill levels fairly.
Yes. If your Course Handicap is 19, you receive one extra stroke on the SI 1 hole (making it two strokes on that hole), plus one stroke on holes SI 2 through SI 18. At 36, you would receive two strokes on every hole.
In match play, you only use the difference between the two players' handicaps. The higher-handicap player receives that difference in strokes, starting on the holes with the lowest Stroke Index (hardest holes). Example: a 10 vs a 16 — the 16-handicap gets 6 strokes on SI 1 through SI 6.
In individual stroke play, most competitions use 100% of Course Handicap. In Stableford, 100% is standard. In four-ball best ball, both players typically use 100%. In foursomes (alternate shot), each pair uses 50% of their combined handicap. In scrambles, common formats use 10%-25% of the team's combined handicap.
Your Handicap Index is your portable skill number (calculated from your best 8 of last 20 scoring differentials). Your Course Handicap is what that index becomes on a specific course and tee set after applying the slope rating and course rating formula. Always use your Course Handicap for the actual tees you are playing.
Yes. If your Course Handicap is 36, you receive 2 strokes per hole (one full round distributed twice). If it is 37, you get an extra third stroke on SI 1. High Course Handicaps simply cycle through the Stroke Index again.
Handicap strokes make golf fair across skill levels. The stroke index on your scorecard tells you exactly which holes are hardest — and those are exactly the holes you get your strokes on first. In stroke play, subtract your strokes from your gross score per hole to get your net score. In match play, only the gap between handicaps matters. Once you understand the system, applying it takes less than a minute per round.
