What Is My Golf Handicap if I Shoot 85?

By Spencer Lanoue
July 24, 2025

Shooting an 85 is a major milestone in golf, and it usually means you've broken the 90 barrier for good. But when other players ask What's your handicap? you might find yourself unsure of the answer. This article will show you exactly how to turn that 85 into a real handicap. We'll walk through the entire process, explaining what a handicap truly represents and how it's calculated using your scores.

First things First: Why a Score of 85 Doesn't Automatically Mean a Handicap of 13

It's easy to assume that since par on most courses is 72, a score of 85 would mean you have a handicap of 13 (85 - 72 = 13). While that math is simple, it's not how the World Handicap System (WHS) works. That number, 13, is your score relative to par for that one round, not your official Handicap Index.

Think of it like this: your Handicap Index is more like your school GPA than a score on a single test. Your GPA isn't based on your final exam alone, it’s an average of your performance across all your classes, factoring in that some classes were harder than others. Similarly, your Handicap Index is a measure of your demonstrated potential, not a simple average of every score you've ever posted. It’s calculated using your best rounds while taking the difficulty of the golf course into account.

This is actually great news. It means the system is designed to reward you for shooting an 85 on a beast of a course and to accurately reflect that a breezy 85 on an easy course is a different kind of performance. Let's break down the key ingredients the system uses to figure this out.

Understanding the Three Key Ingredients of Your Handicap

To accurately calculate a handicap, the WHS needs more than just your final score. It considers three specific elements to create a standardized number for every round you play. Understanding these concepts is the first step to seeing how your 85 fits into the bigger picture.

1. Adjusted Gross Score (AGS)

Have you ever had one disastrous hole ruin an otherwise solid round? A snowman (an 8) on a par 4 or that dreaded 10 on a par 5? The WHS has a built-in safety net for this called Adjusted Gross Score, which uses a "Net Double Bogey" to put a maximum score on any single hole.

Net Double Bogey is calculated as: Par of the hole + 2 strokes + any handicap strokes you receive on that hole.

Don't worry if you don't know your exact handicap yet to determine your strokes per hole. In the beginning, if you're officially posting scores for the first time, you have an initial handicap limit. For men, it might be 18 strokes (one per hole), and for women, maybe 24. A more direct way to think about it for now is that you can't post a score higher than a triple-bogey for handicap purposes if you're a high-handicapper just starting out.

Let's use a clear example. You're playing a tough Par 4 that is ranked as the #1 handicap hole on the course, meaning you'd definitely get a stroke on it.

  • Par is 4.
  • Double Bogey is +2.
  • Your handicap stroke is +1.
  • Your max score on this hole is 4 + 2 + 1 = 7.

So, even if you found the water hazard, then the deep stuff, and eventually carded a 9, the score you'd enter for your handicap calculation would be adjusted down to a 7. This prevents that one big mistake from unfairly inflating your Handicap Index. When you shoot an 85, you likely have a hole or two that get adjusted down, making your AGS slightly lower than your 85.

2. Course Rating™

Course Rating is the baseline for a course's difficulty. Put simply, **it’s the score a scratch golfer (a 0 handicap) is expected to shoot on that course from a specific set of tees.** It’s usually a number very close to the par of the course, but it can be higher or lower.

For example:

  • Course A: Par 72, Course Rating 70.8
  • Course B: Par 72, Course Rating 73.5

A scratch golfer would be expected to shoot a 70.8 on Course A (over a stroke under par) and a 73.5 on Course B (over a stroke over par). This tells you immediately that Course B is a more difficult test for an expert player. The rating takes into account factors like length, hazards, and green complexity.

3. Slope Rating®

If Course Rating is the difficulty for a scratch golfer, the Slope Rating evaluates **how much more difficult the course is for a bogey golfer (someone who shoots around a 90) compared to a scratch golfer.**

The number ranges from 55 (easiest) to 155 (most difficult), with 113 being the standard for a course of "average" relative difficulty. A high Slope Rating (e.g., 140) means the course gets significantly tougher for the mid-to-high handicapper. It punishes mistakes more severely. Think of long carries over water or courses with thick rough and slick, fast greens. A scratch player might handle these, but a bogey golfer will find them much more challenging.

Seeing a high Course Rating and a high Slope Rating on the scorecard is a clear signal that you’re in for a tough round.

Let's Calculate! Turning Your 85 into a Handicap Differential

Now that we have the ingredients, we can plug them into the formula the WHS uses to calculate a "Handicap Differential" for your round. This is the magic number that converts your 85 into a standardized value that can be compared to any other round, on any other course.

The Handicap Differential Formula

The calculation looks like this:

(Adjusted Gross Score - Course Rating) x 113 / Slope Rating

Let's see how this works in practice by taking your score of 85 and applying it to two different types of courses. For this example, we'll assume your Adjusted Gross Score is also 85.

Example 1: Your Friendly Home Course

You tee it up at your local course. It's fair and you know it well. You shoot a solid 85.

  • Adjusted Gross Score: 85
  • Course Rating: 70.8
  • Slope Rating: 120

Let's do the math:

  1. (85 - 70.8) = 14.2
  2. 14.2 x 113 = 1604.6
  3. 1604.6 / 120 = 13.37

For this round, your Handicap Differential is 13.4. You can see it’s pretty close to the simple 13-over-par guess, because the course ratings were fairly standard.

Example 2: A Brutal Championship Course

A few weeks later, you play a famous course known for its difficulty while on a golf trip. You grind it out, play great, and post the same score: 85.

  • Adjusted Gross Score: 85
  • Course Rating: 73.5
  • Slope Rating: 138

Now, let's plug these values into the formula:

  1. (85 - 73.5) = 11.5
  2. 11.5 x 113 = 1299.5
  3. 1299.5 / 138 = 9.41

Your Handicap Differential for this round is a stellar 9.4. This is the beauty of the System: it recognized that your 85 on this incredibly tough course represented a much better performance than the 85 you shot at your local muni. It was almost four strokes better!]

From Differential to Handicap Index: Bringing It All Together

Your Handicap Index isn’t based on a single round, but on an average of your best ones. The WHS takes the **best 8 of your most recent 20 Handicap Differentials** and averages them to calculate your official Handicap Index.

Let's imagine you are a golfer who usually shoots around 85. Your last 20 scores would have produced 20 differentials. Some days you shot an 88 and had a higher differential, other days you went low with an 82 for a great one. Let's say the system identifies your best 8 differentials as:

  • 9.4 (that lights-out round on the tough course)
  • 10.2
  • 10.8
  • 11.5
  • 11.9
  • 12.3
  • 12.6
  • 13.1

To find your Handicap Index, we simply average these eight numbers:

(9.4 + 10.2 + 10.8 + 11.5 + 11.9 + 12.3 + 12.6 + 13.1) / 8 = 91.8 / 8 = 11.475

So, for a golfer who consistently shoots around 85 on courses of varying difficulty, your Handicap Index would likely be around an 11.5.

So, What Does This Actually Mean For My Game?

An 11.5 handicap puts you in a fantastic category of golfers. It means you're well above average and can handle yourself on almost any course. It does not mean you're expected to shoot an 83 or 84 every time you play (72 + 11.5). Remember, your handicap reflects your potential on a good day. It's an average of your best rounds.

An 11.5-handicapper likely has a scoring range that looks something like this:

  • Great Day: 81-83
  • Typical Day: 84-88
  • Tough Day: 89-92

Scoring an 85 consistently proves you have excellent fundamentals and course management skills. You've officially left the world of hoping to break 90 and are now on the verge of becoming a single-digit handicap - an amazing accomplishment that less than a quarter of all golfers ever achieve. The path from here is all about refining your game, managing mistakes, and turning those few blow-up holes that lead to an 88 into pars and bogeys that keep your score at 84.

Final Thoughts

Breaking 90 and shooting 85 is a tremendous achievement, and now you understand how that translates into a Handicap Index. It's a nuanced process that factors in your best rounds and the difficulty of the course, giving you a number around 11.5, which accurately reflects your true playing potential.
