Your Handicap Index travels with you; the strokes used for a particular round depend on the tees and format. Start with your current Index, the correct Course Rating, Slope Rating and par, then use the competition’s handicap allowance. This guide describes the U.S. World Handicap System process; check your national association for local administration.
Three numbers with different jobs
Swipe the table, or focus it and use the arrow keys to see every column.
| Number | What it describes | Where to use it |
|---|---|---|
| Handicap Index | Demonstrated playing ability on a standardized scale. | The starting value in your authorized handicap record. |
| Course Handicap | Strokes associated with a particular set of tees before an allowance. | Course-based adjustments, including maximum hole scores for posting. |
| Playing Handicap | The strokes used for the chosen competition format. | Applying the committee’s allowance and scoring the competition. |
An Index is not a prediction that you will shoot that many strokes over par every round. With 20 scores in the record, the basic calculation uses the lowest eight Score Differentials; safeguards and other adjustments also apply. A Differential accounts for course difficulty and other prescribed factors, so averaging eight raw scores is a different calculation. See the USGA Rules of Handicapping, Rule 5.2b.
Calculate for the tees you will actually play
For an 18-hole U.S. calculation: Course Handicap = Handicap Index × (Slope Rating ÷ 113) + (Course Rating − par). Keep the unrounded result for the Playing Handicap calculation. Multiply it by the applicable allowance and then round to the nearest whole number. For posting adjustments, round the Course Handicap itself. These are the USGA calculation and rounding instructions.
Use the official Course Handicap calculator or your authorized service. Verify the course, tee name, rating set and number of holes. A different tee’s rating can change the result even if its par is identical. Nine-hole calculations have their own inputs; avoid halving an 18-hole result by assumption.
Separate the playing score from the posting adjustment
After an Index is established, the maximum hole score for handicap posting is net double bogey: par + 2 + the handicap strokes received on that hole based on Course Handicap. The USGA net-double-bogey guidance distinguishes this from the rule used before an Index exists.
Use the stroke-index allocation on the scorecard to establish strokes by hole. Competition scoring and permission to pick up depend on the format; the handicap cap alone does not create a maximum-score competition.
Build a reliable posting routine
- Before play, confirm that the round will meet acceptable-score requirements and note the tee set.
- Record actual hole scores and any holes not played or not completed so the correct procedure can be applied.
- Post promptly using the correct date, course and tees. Follow your association’s current process for nine holes and incomplete rounds.
- If the record is wrong, contact your club or handicap committee with the original scorecard and the specific correction.
For a first Index, ask an authorized club or association how to join and establish a record. U.S. players generally need 54 holes in acceptable combinations of nine- and 18-hole scores. The USGA getting-started FAQ explains the minimum. An app that averages scores may offer a useful personal statistic without maintaining an official Index.
Keep the USGA handicapping hub handy for revisions. If a calculation disagrees with your service, first compare the date of the Index, tee ratings, par, allowance and rounding sequence.
