Your scorecard says 95, but the score you post for your handicap might be 91. This isn't cheating, it's a core part of the game called an adjusted golf score, and it's what keeps the handicap system fair for everyone. This article will show you exactly how to do it, breaking down the simple, step-by-step process of turning your actual score into the official one you submit for your handicap.

What Exactly Is an Adjusted Golf Score?
Think of an adjusted gross score as your raw score with a safety net. Under the World Handicap System (WHS), there's a maximum number you can take on any single hole for handicap purposes. One disastrous hole where you put three in the water and take a 10 shouldn't completely inflate your handicap, as that score might not reflect your true playing ability. The adjustment process smooths out those outlier holes, giving a more accurate picture of your potential.
The system used to apply this safety net is called Net Double Bogey. It sounds a bit complicated, but it's very straightforward once you understand the components. By applying this simple limit to each hole, you get to your "adjusted gross score," which is the only number you should be posting to maintain your Handicap Index®.

Before we walk through the step-by-step calculation, let's get familiar with a few terms that are fundamental to the process. You'll find most of what you need right on your scorecard or posted in the pro shop.
Your Course Handicap
This is the number of strokes you get for the specific course and set of tees you’re playing on a given day. It's different from your Handicap Index, which is your general ability rating. Your Course Handicap adjusts your Index based on the difficulty of the course (its Slope Rating and Course Rating). You can usually find a chart in the clubhouse or near the first tee that lets you look up your Handicap Index and find your corresponding Course Handicap for the tees you're playing.
Example: If your Handicap Index is 18.5, you might find that your Course Handicap from the white tees is 20.
Strokes Per Hole (Stroke Index)
Your Course Handicap translates to strokes you "get" on certain holes. Every scorecard has a line labeled "Handicap" or "Stroke Index" (S.I.) with numbers from 1 to 18. This ranks the holes from hardest (1) to easiest (18).
If your Course Handicap is 15, you get one stroke on the holes with a Stroke Index of 1 through 15.
If your Course Handicap is 22, you get one stroke on every hole (1-18) and a second stroke on the four hardest holes (Stroke Index 1, 2, 3, and 4).
Knowing this is the first step toward figuring out your max score on any hole.
The Golden Rule: Net Double Bogey
This is it - the simple formula that determines your maximum score per hole for handicap purposes.
Net Double Bogey = Par for the hole + 2 + any handicap strokes you receive on that hole.
Once your actual score on a hole exceeds this number, you adjust it down to the Net Double Bogey value. If your score is equal to or less than your Net Double Bogey, you just record your actual score. That's a good way to stay on track on the course as well. Once you hit your Net Double Bogey number for the hole, just pick up your ball and move on to the next hole since that is your "Equitable Stroke Control" anyway.
How to Calculate Your Adjusted Golf Score: Step-by-Step
Now, let's put it all together. Grab your last scorecard, and we'll walk through the process. For this example, let's imagine our golfer, Alex, has a Course Handicap of 20.
Step 1: Go Through Your Scorecard Hole-by-Hole
Don't try to do it all in your head. The best way is to sit down with your scorecard and review one hole at a time. For each hole, check your actual score against what your maximum score would have been.
Step 2: Calculate the Max Score (Net Double Bogey) for Each Hole
With a Course Handicap of 20, Alex gets one stroke on all 18 holes, plus a second stroke on the two hardest holes (Stroke Index 1 and 2).
Example A: A Good Hole
Hole: #4, a Par 4
Stroke Index: 15
Alex's Actual Score: 5 (a bogey)
First, calculate Alex's max score. Alex gets one stroke on this hole (since the Stroke Index of 15 is less than his Course Handicap of 20). Net Double Bogey = Par (4) + 2 + Handicap Strokes (1) = 7
Alex's score of 5 is less than 7, so there's no adjustment needed. The score for this hole remains a 5.
Example B: A Blow-Up Hole
Hole: #7, a Par 5
Stroke Index: 1
Alex's Actual Score: 10
This is the hardest hole on the course. Since Alex has a Course Handicap of 20, he gets two strokes on this hole. Now, let’s calculate his max score here. Net Double Bogey = Par (5) + 2 + Handicap Strokes (2) = 9
Alex's actual score of 10 is higher than his maximum allowable score of 9. Therefore, for handicap purposes, he must adjust this score down from 10 to 9.
Example C: In-Between Hole
Hole: #12, a Par 3
Stroke Index: 18
Alex's Actual Score: 6
This is the easiest hole on the course, but Alex still gets one stroke here because of his Course Handicap of 20. Net Double Bogey = Par (3) + 2 + Handicap Strokes (1) = 6
Alex's actual score of 6 is exactly his Net Double Bogey. So, in this case, there's no adjustment. His score stays at 6. Had he scored a 7, he would have had to adjust it down to 6.
This is what the completed process might look like for a few holes on Alex's card:
Once you’ve gone through all 18 holes, making any necessary downward adjustments, add up the new hole-by-hole scores. This final number is your Adjusted Gross Score. This is the score that gets reported to GHIN or your handicap service.
Let's say Alex's raw score (the actual strokes he took) was 101. But after adjusting the score on hole #3 from a 10 down to a 9, and another adjustment on hole #14 from an 8 to a 7, his Adjusted Gross Score might be 98. That score of 98 is what he posts.

It's tempting for some golfers to think this is a way to artificially lower their handicap, but its purpose is the exact opposite. It's designed to stop your handicap from becoming artificially high. An outlier blow-up hole simply doesn’t reflect your general playing ability, so the system is designed to moderate that impact.
Posting your adjusted scores correctly and consistently is good for you and everyone you play with. It allows your Handicap Index to accurately reflect your skill, making for fairer and more enjoyable matches when strokes are involved. It’s a habit every golfer should build, just like repairing a ball mark or raking a bunker.
