Picture a charity golf day where half the players have an official handicap and half have never kept one. How do you give everyone a fair shot? One of the oldest and most popular answers is the Callaway system. It figures out a handicap for each golfer after the round, using the player’s own worst holes.
This guide explains Callaway system golf in plain language. You will learn how Callaway golf system scoring works, see the full table, follow worked examples, and get a simple Callaway scoring system calculator method you can build in a spreadsheet. We also cover the Callaway scoring system for 9 holes and for a scramble, so you can run any event with confidence.
What Is the Callaway System in Golf?
The Callaway system is a one-day handicap method used in stroke play events. Instead of using a handicap that a golfer already carries, it creates a temporary handicap from the round itself. The player’s gross score decides how many of their worst holes can be deducted. The total of those holes, plus or minus a small adjustment, becomes the day’s handicap.
It is named after Lionel F. Callaway, a golf professional from Pinehurst, North Carolina, who published the method in the 1940s and 1950s. It remains common in charity events, corporate outings, and club days where many players do not have an official handicap.
Why Organizers Like It
- No handicap cards or official records needed
- Easy to explain and calculate after the round
- Rewards steady play, since wild blow-up holes can be removed
- Works for a mixed field of experienced and casual golfers
Important: A Callaway handicap is not an official handicap. It is used only for that day’s competition, and the result cannot be used to build a handicap index.
Callaway Golf System Scoring: Step by Step
- Play 18 holes and record every score. Players use normal stroke play.
- Apply the double-par limit. No hole can count for more than twice its par. That means 6 on a par 3, 8 on a par 4, and 10 on a par 5.
- Add up the adjusted gross score. This is the total after the double-par limit has been applied.
- Adjust for par if needed. The standard chart is built for a par-72 course. On a par-71 course, subtract 1 from the gross before using the table, and on a par-70 course, subtract 2.
- Look up the adjusted gross in the Callaway table. The table tells you how many worst holes you can deduct and what adjustment to make.
- Find your worst holes. The 17th and 18th holes cannot be deducted. Some events also exclude the 16th, so check the rules.
- Add the scores of those worst holes. This is your starting handicap.
- Apply the small adjustment. Add or subtract 1 or 2 strokes, as shown in the table.
- Calculate your net score. Subtract the final handicap from your gross score. The lowest net score wins.
The Callaway Scoring Chart (Par 72)
Use this table with the adjusted gross score after the double-par limit. These numbers match the traditional chart.
| Adjusted Gross Score | Worst Holes You May Deduct |
|---|---|
| 72 or lower | None (scratch, use gross score) |
| 73 to 75 | ½ worst hole, plus adjustment |
| 76 to 80 | 1 worst hole, plus adjustment |
| 81 to 85 | 1½ worst holes, plus adjustment |
| 86 to 90 | 2 worst holes, plus adjustment |
| 91 to 95 | 2½ worst holes, plus adjustment |
| 96 to 100 | 3 worst holes, plus adjustment |
| 101 to 105 | 3½ worst holes, plus adjustment |
| 106 to 110 | 4 worst holes, plus adjustment |
| 111 to 115 | 4½ worst holes, plus adjustment |
| 116 to 120 | 5 worst holes, plus adjustment |
| 121 to 125 | 5½ worst holes, plus adjustment |
| 126 to 130 | 6 worst holes, plus adjustment |
| 131 to 135 | 6½ worst holes, plus adjustment |
The traditional chart keeps going in the same pattern (half a hole more for every five strokes). The maximum total deduction under the system is 50 strokes.
How the Adjustment Works
Each row of the chart has five scores, and each one carries a different adjustment. The first score in the row is −2, then −1, 0, +1, and +2 for the last. For example:
- A score of 76 earns −2, while 80 earns +2.
- A score of 81 earns −2, while 85 earns +2.
- A score of 96 earns −2, while 100 earns +2.
- In the shorter row, 73 earns −2, 74 earns −1, and 75 earns 0.
The adjustment keeps golfers at the low end of a row from getting too big a benefit and gives a little extra to those at the high end.
How Half Holes Work
When the table says “1½ worst holes,” you deduct the worst hole in full and half of the next worst hole. When it says “½ worst hole,” you deduct half of your single worst hole. Round half strokes up, so half of 7 becomes 4.
Callaway System Golf Handicap Examples
Example 1: A Higher-Scoring Golfer
Sam shoots 96 on a par-72 course, and none of his holes was higher than double par.
- The table gives 3 worst holes for 96, with an adjustment of −2.
- Sam’s worst holes in the first 16 are a 7, an 8, and an 8, which total 23.
- Handicap = 23 − 2 = 21.
- Net score = 96 − 21 = 75.
Example 2: A Steadier Golfer
Priya shoots 78. Her worst hole in the first 16 holes was a 7.
- The table gives 1 worst hole for 78, with an adjustment of 0.
- Handicap = 7 + 0 = 7.
- Net score = 78 − 7 = 71.
Example 3: A Half-Hole Case
Lee shoots 74 with a worst hole of 6 among the first 16 holes.
- The table gives ½ worst hole for 74, with an adjustment of −1.
- Half of 6 is 3. Handicap = 3 − 1 = 2.
- Net score = 74 − 2 = 72.
Example 4: When the Double-Par Limit Matters
Jordan makes a 9 on a par 4. For Callaway purposes, that hole counts as an 8, so the adjusted gross score is one lower than the actual total. If Jordan shot 100 with that 9, the adjusted gross is 99, which still falls in the 96 to 100 row.
Callaway Scoring System Calculator: Build Your Own
You do not need special software to calculate Callaway scores. A simple spreadsheet works. Follow these steps for each player:
- Enter 18 hole scores and the 18 hole pars.
- Apply the double-par limit to each hole, so the capped score equals the smaller of the actual score and twice the par.
- Add the capped scores to get the adjusted gross, then subtract the difference from par 72 if the course is not a par 72.
- Find the worst-hole entitlement using the chart or the pattern below.
- Add the largest capped scores from holes 1 to 16, using only the number of holes you are allowed.
- Apply the adjustment and calculate the net score.
The table follows a clean pattern, which makes it easy to automate. Using G for the adjusted gross score (converted to a par-72 basis):
- Worst holes: 0 if G is 72 or lower, ½ if G is 73 to 75, and 1 + 0.5 × (whole number of (G − 76) ÷ 5) if G is 76 or higher.
- Adjustment: 0 if G is 72 or lower, G − 75 if G is 73 to 75, and the remainder of (G − 76) ÷ 5, minus 2, if G is 76 or higher.
Check it against the earlier examples: for G = 96, the whole number of 20 ÷ 5 is 4, so worst holes = 1 + 2 = 3, and the remainder is 0, so the adjustment is −2. That matches the chart.
If you are running a bigger event, you can also feed these results into a live display. See how to make a golf leaderboard for ideas.
Callaway Scoring System 9 Holes
The classic Callaway chart was built for 18 holes. There is no single official nine-hole table, so organizers use one of two approaches. Decide which one before the round and print it on the rules sheet.
Option 1: The Scaled Method
- Double the nine-hole adjusted gross score to create an 18-hole equivalent.
- Look up that number in the standard table.
- Cut the entitlement in half. For example, 3 worst holes becomes 1½ holes, and a −2 adjustment becomes −1.
- Choose the worst holes from the first eight holes, so the last hole cannot be deducted.
- Subtract the final handicap from the nine-hole gross score.
Example: A player shoots 48 on a par-36 nine, with hole scores of 6, 5, 6, 4, 7, 5, 4, 6, and 5.
- Doubled score is 96, which gives 3 worst holes and a −2 adjustment on the 18-hole table.
- Halved, that is 1½ holes and a −1 adjustment.
- Holes 1 to 8 are eligible. The worst is a 7, and the next worst is a 6, so the deduction is 7 + 3 (half of 6) = 10.
- Handicap = 10 − 1 = 9.
- Net score = 48 − 9 = 39.
Option 2: A Simple League Table
Some nine-hole leagues create their own short table, for example, 1 worst hole for 40 to 44, 2 for 45 to 49, and so on, and exclude only the ninth hole. This works if everyone knows the rule in advance, but it is not an official Callaway table, so label it clearly as a league version.
For other nine-hole formats, read our golf league formats guide.
Callaway Scoring System for Scramble
Using Callaway with a scramble is tricky. In a scramble, the team plays one ball, so the team score is often far below par. If a team shoots 62 on a par-72 course, the standard Callaway table gives it a scratch handicap, which makes the system useless.
That is why most organizers choose one of these routes instead:
- Use a scramble handicap allowance. The World Handicap System recommends 25%, 20%, 15%, and 10% of a four-player team’s Course Handicaps (lowest to highest), and 35% of the lower plus 15% of the higher for a two-player team. See Appendix C of the Rules of Handicapping from the USGA.
- Run Callaway for individuals first. Some events play a shamble or best ball, which produces individual scores, and then use Callaway to calculate net results.
- Create a shifted table. A few organizers agree on a number to add to the team score before using the table, so a typical scramble result lands in a useful range. This is an organizer’s choice, not an official Callaway rule, so publish it clearly.

What Is a Texas Scramble Golf Tournament, and Can It Use Callaway?
A Texas scramble golf tournament is a scramble in which each player’s tee shot must be used a minimum number of times. Because it still produces a single team score, the same issue applies: Callaway alone rarely fits. Use a scramble allowance for team events, and keep Callaway for individual stroke play days. Our full guide on what a Texas scramble is covers the rules, drive tracker, and strategy.
Callaway vs the World Handicap System
| Feature | Callaway System | World Handicap System |
|---|---|---|
| Handicap source | Calculated from that day’s round | Built from many past rounds |
| Official? | No, one-day use only | Yes |
| Needs a handicap index? | No | Yes |
| Best for | Charity days, outings, club events with mixed fields | Regular play and posted scores |
| Fairness over time | Moderate | Higher |
To understand official handicaps, read about the golf handicap index, course handicap, course handicap vs playing handicap, and handicap allowance. For a quick explanation of a top-level player, see what a scratch golfer is.
Callaway vs Other Handicap Methods
- Peoria system: before the round, players secretly choose six holes whose scores will be used to work out handicaps after play. It is a similar idea, but the hidden holes are picked in advance.
- Stableford: points replace strokes, so a bad hole costs little. It is not a handicap method, but it gives a similar “bad holes don’t ruin you” feel. See our better ball golf format guide for the Stableford point table.
- Net double bogey: a cap used for official handicap scoring. Learn more in what net double bogey is.
Pros and Cons of the Callaway System
Advantages
- No official handicap needed
- Easy to teach on the day of the event
- Keeps high-scoring players competitive
- Works well for stroke play events with mixed skill levels
- Removes the pain of one disastrous hole
Drawbacks
- Results are not official and cannot count for a handicap
- It can be gamed by a golfer who plays poorly on purpose
- Calculations take time after the round
- Not a natural fit for scrambles or other team formats
- Variations (16th hole, tie-breakers) can cause confusion
Tips for Organizers Using the Callaway System
- Announce the variation. State whether the 16th hole can be deducted and how ties are broken.
- Print the chart on the scorecard or rules sheet. Players like to see the numbers.
- Use scorecards with pars. The double-par limit depends on each hole’s par.
- Plan a scoring desk. Have two people calculate results so errors are caught quickly.
- Use a spreadsheet. Build the formulas before the day and test them with sample scores.
- Set a tie-break rule. A common one is to award the tie to the player with the lower gross score or lower handicap.
- Watch for sandbagging. Ask players to keep honest scores, and consider a rule that scores out of line with the field may be reviewed.

Common Callaway Mistakes to Avoid
- Forgetting to cap each hole at double par before adding the total.
- Deducting the 17th or 18th hole.
- Using the par-72 table on a par-70 or par-71 course without converting.
- Applying the adjustment in the wrong direction.
- Rounding half holes down instead of up.
- Mixing 18-hole and 9-hole tables.
- Treating the Callaway handicap as an official handicap.
Frequently Asked Questions
What is the Callaway system in golf?
It is a one-day handicap method that deducts a player’s worst holes, based on their gross score, to calculate a net score.
How do you calculate a Callaway handicap?
Cap each hole at double par, add up the adjusted gross, find the number of worst holes in the table, total those holes (excluding the 17th and 18th), and apply the adjustment. Subtract the result from the gross score.
Why can’t you deduct the 17th and 18th holes?
The rule stops players from throwing away the last holes once they know what score they need. It keeps the finish honest.
What is the maximum Callaway handicap?
The traditional system caps the total deduction at 50 strokes.
Can you use the Callaway system on a par-70 course?
Yes. Subtract the difference from par 72 from the adjusted gross score before using the table. For par 70, subtract 2.
Is the Callaway system an official handicap?
No. It is a temporary method for one event and is not part of the World Handicap System.
How does the Callaway system work for 9 holes?
There is no single official table. A common method is to double the nine-hole score, use the 18-hole table, then halve the number of worst holes and the adjustment. Announce your method before play.
Can the Callaway system be used for a scramble?
It is not a good fit, because scramble scores are very low. Most events use a scramble handicap allowance instead.
What happens if two players tie on net score?
Rules vary. A common approach is to give the win to the player with the lower handicap or lower gross score. Announce it in advance.
How is the Callaway system different from the Peoria system?
Callaway uses a player’s actual worst holes after the round. Peoria uses six holes chosen secretly before the round and applies a formula to the scores on them.
Final Thoughts
The Callaway system is one of the simplest ways to make a stroke play day fair for everyone, even when most players have no official handicap. Cap each hole at double par, find your entitlement in the table, deduct the worst holes (never the last two), apply the small adjustment, and compare net scores.
Announce your variations, test your spreadsheet, and keep everyone honest. With those pieces in place, your next outing will run smoothly, and every golfer will feel they had a fair chance.
