Let the App Handle the Handicap Math
Settle Up Golf tracks every bet, calculates every payout, and tells you exactly who owes what, so you can focus on your game.
What your handicap number actually means, how it's calculated, and how strokes get applied when you're playing for money.
A golf handicap is a number that represents your potential playing ability. The lower your handicap, the better you play. A scratch golfer has a handicap of 0, they're expected to shoot right around par. A 20-handicapper typically shoots about 20 strokes over par on a given course.
The key word is potential. Your handicap isn't based on your average score, it's based on your best recent rounds. The World Handicap System (WHS), which is used internationally today, calculates your Handicap Index from the best 8 of your last 20 scored rounds. This means a slightly "streaky" player will carry a lower handicap than their average performance might suggest, which is by design.
The handicap system exists for one reason: to let golfers of different skill levels compete fairly against each other. Without it, a 5-handicap playing a 25-handicap would be a foregone conclusion every single time. With it, anyone can have a legitimate chance on a given day.
Here's where a lot of golfers get confused, and it's worth understanding because it directly affects how your strokes are calculated when you're playing a money game.
Your Handicap Index is the number associated with your GHIN number or golf app profile. It's a portable measure of your ability that travels with you everywhere. Whether you're playing a links course in Scotland or a mountain track in Colorado, your Handicap Index stays the same.
Your Course Handicap is different. It's a number specific to a particular set of tees on a particular course, and it's the number you actually use on the scorecard. A course handicap accounts for how difficult that specific set of tees is, adjusted by the course's Slope Rating and Course Rating.
The distinction matters because the same player might have a Course Handicap of 12 from the white tees and 15 from the blue tees, tougher tees mean more strokes.
The formula under the World Handicap System is:
Course Handicap = Handicap Index × (Slope Rating ÷ 113) + (Course Rating − Par)
Don't worry, you don't need to do this math in your head. The scorecard usually has a conversion table printed on it, and apps like Settle Up Golf handle the calculation automatically when you enter player handicap indexes before your round.
To understand what's happening: Slope Rating measures how much harder a course is for a bogey golfer compared to a scratch golfer (113 is the "average" slope). A slope of 130 means the course is relatively more demanding on higher handicappers, so they receive more strokes. Course Rating is the expected score for a scratch golfer, and subtracting par adjusts for courses where par might be 70 or 72.
If you only remember one thing from this page, make it this. Under the World Handicap System there are three related numbers, and people mix them up constantly. They build on each other in a clear chain, so once you see the order it stops being confusing.
The formula chain runs in this order:
Handicap Index → Course Handicap = Index × (Slope ÷ 113) + (Course Rating − Par) → Playing Handicap = Course Handicap × allowance
So your Index never changes from tee to tee, your Course Handicap goes up or down with the difficulty of the tees you choose, and your Playing Handicap is the final stroke count after any allowance the format calls for. For most weekend rounds the allowance is 100 percent, so the Course Handicap and the Playing Handicap are the same number. Where you see a difference is in net stroke-play events or team formats that trim everyone to 85 to 95 percent to tighten the field.
Numbers make this concrete. Say you have a Handicap Index of 10.4 and you are playing a set of tees rated slope 131, course rating 71.2, par 72. Here is the math step by step.
That player receives 11 strokes, one on each of the 11 hardest holes (stroke index 1 through 11). Now picture the whole foursome on those same tees:
Notice how a tougher slope spreads the players further apart, while an easier slope pulls them closer together. That is the whole point of the Slope Rating, and it is why you should always recalculate when the group moves up or back a set of tees. Apps like Settle Up Golf run this chain for every player the moment you pick a course and tee, so nobody has to do the arithmetic on the first box.
People search for things like "1 golf handicap" or "2 handicap golf" because the number alone does not tell you much until you translate it into scoring. Here is a rough guide to what each level represents in skill terms. Real results vary by course difficulty and conditions, so treat these as ballpark expectations rather than guarantees.
| Handicap | Typical score on a par 72 | What it means |
|---|---|---|
| 0 (scratch) | About even par, 72 | Elite amateur. Shoots par or better on a good day. Roughly the top 2 percent of golfers. |
| 1 | 73 to 74 | Near-scratch. A genuinely excellent player who breaks par regularly but not every round. A 1 handicap gets a stroke only on the single hardest hole. |
| 2 | 74 to 75 | Top-tier single digit. Two strokes on the two hardest holes. Very strong ball striker who rarely posts a big number. |
| 3 | 75 to 76 | Strong single digit. Consistently in the mid-70s, competitive in most club events. |
| 5 | 77 to 78 | Solid single-digit player. Breaks 80 most rounds. The skill bar where the game starts to look easy to onlookers. |
| 10 | 82 to 84 | Better-than-average golfer. Flirts with breaking 80 on a hot day, usually shoots low-to-mid 80s. |
| 18 (bogey golfer) | About 90 | The classic "bogey golfer," averaging one over par per hole. Gets a stroke on every hole. Very common for committed recreational players. |
The big takeaway: anything in the single digits is genuinely good golf, and a 1, 2 or 3 handicap is the kind of number you only reach by playing a lot and scoring well consistently. For context, the average male golfer carries a handicap in the mid-teens and the average female golfer in the high 20s, so a low single digit puts you well ahead of most players you will ever tee it up with.
Scorecards, apps and golf forums are full of shorthand. Here is a quick glossary so the abbreviation for handicap in golf never trips you up again.
Once you have everyone's Course Handicap, you need to figure out which holes those strokes apply to. That's where the Stroke Index (sometimes called Handicap Index on the scorecard) comes in.
Every hole on the scorecard is assigned a rank from 1 to 18. The hole ranked 1 is considered the hardest hole on the course, that's where a single-stroke player would receive their stroke. The hole ranked 18 is the easiest.
The rule is simple: you receive strokes on the hardest holes first. If your Course Handicap is 5, you get one stroke on each of the five hardest holes (stroke index 1 through 5). If your Course Handicap is 18, you get one stroke on every hole. If it's 20, you get two strokes on the two hardest holes and one stroke on the other 16.
In practice, before teeing off in a money game, it's worth taking a minute to circle the holes on the scorecard where each player receives strokes. It avoids confusion mid-round when a hole result is close.
Once you understand stroke holes, the math is easy:
So if you make a 5 on a par-4 where you receive a stroke, your net score is 4, a net par. If your opponent makes a clean 4 with no stroke, you've halved the hole on a net basis.
Most recreational money games are played on net scores, which is what makes them competitive across different skill levels. Playing gross is an option, but it generally only works when players are closely matched.
In match play, you compare net scores hole by hole. The lower net score wins the hole; the higher net score loses it; equal net scores halve it. Handicap strokes are applied exactly as described above, the higher-handicap player receives strokes on the appropriate holes, making those holes more equitable.
In a Nassau, the most popular money game format, you're essentially playing three match play contests: the front 9, the back 9, and the full 18. Handicap strokes still apply on each hole they fall on. On a 9-hole match, strokes are assigned by the stroke index for those specific holes.
When four players are involved and you're playing team formats, the usual approach is to compute the net strokes for each player individually, then use those net scores to determine hole winners.
In a skins game, each hole is worth a set amount of money. Ties carry over. Handicap strokes are applied per hole, so a high-handicapper has a realistic chance of posting a net birdie or net eagle to win a skin, even against much better players.
Net skins are the fairest way to run a money game across a mixed-ability group. Without handicaps, the better players would win almost every skin and lower handicappers would go home empty-handed. With net scoring, anyone can hole out and walk away with the pot. If you want to see how the strokes shake out before you play, try the free skins calculator.
In many casual money games, players don't use their full Course Handicap. Instead, they play "off the low", meaning the lowest-handicap player in the group plays scratch, and everyone else receives only the difference between their handicap and the lowest player's.
For example: if your four players have Course Handicaps of 4, 10, 14, and 18, you subtract 4 from everyone. The adjusted handicaps become 0, 6, 10, and 14. The best player plays scratch; the others get their relative strokes.
Why do this? A few reasons:
Settle Up Golf supports both approaches, you can play full handicaps or off the low, and the app calculates stroke holes automatically either way.
Handicaps only work if everyone plays by roughly the same rules. Here are a few things that help keep money games fun and fair:
If you do not have a GHIN subscription but still want a running handicap that reflects your current play, the Settle Up Golf app calculates a WHS-style index for you. Every round you post in the app feeds your Settle Up Index, using the same 8-of-last-20 math the official system uses. It is not a replacement for GHIN if you need the official number for a tournament, but for side bets and casual play it works fine. See the step-by-step guide for how to find it and how to exclude rounds you do not want counted.
Anything under 10 is good golf, and a single-digit handicap puts you ahead of most players you will meet. The average male golfer sits in the mid-teens and the average female golfer in the high 20s, so breaking into single digits is a real milestone. A handicap of 0, called scratch, means you play to roughly par and ranks among the top few percent of all golfers.
A 1 Course Handicap means one stroke, and you receive it on the single hardest hole, the one ranked stroke index 1 on the scorecard. On every other hole you play to gross. In scoring terms a 1 handicap typically shoots around 73 to 74 on a par 72.
Your Handicap Index is a portable ability number to one decimal that stays the same wherever you play. Your Course Handicap converts that Index into the whole number of strokes you actually get on a specific set of tees, using the formula Index × (Slope ÷ 113) + (Course Rating − Par). The Index is your skill; the Course Handicap is how many strokes that skill earns you on the tees in front of you today.
WHS stands for the World Handicap System, the global standard introduced in 2020 that unified six older regional handicap systems into one set of rules. It is the system that calculates your Handicap Index from the best 8 of your last 20 score differentials.
