Ever feel like you played great but your scorecard didn't show it? Or maybe you think your putting is holding you back, only to spend weeks practicing it without seeing any real improvement. Frustrating, right? There’s a better way to understand your game, and it’s called Strokes Gained. This single concept has revolutionized how professional golfers practice and play, and it’s finally accessible to amateurs who want to make smarter decisions and shoot lower scores. This guide will walk you through exactly what Strokes Gained is, why it matters more than your other stats, and how you can start tracking it yourself.
What is Strokes Gained (And Why Should You Care)?
For decades, we’ve measured our golf games with basic stats: Fairways in Regulation (FIR), Greens in Regulation (GIR), and Putts Per Round. While these numbers aren't useless, they often lie. Let me explain.
Imagine two golfers, Golfer A and Golfer B. They both shoot 90 and have 36 putts. On paper, their putting performance looks identical. But what if Golfer A’s 36 putts came from an average distance of 15 feet, and Golfer B’s came from an average of 40 feet? Suddenly, it’s obvious Golfer A had a poor day on the greens, while Golfer B was a lights-out lag putter whose approach shots were letting them down.
This is the problem Strokes Gained solves. It adds context to every shot. Instead of just counting shots, it measures the quality of each shot against a benchmark - typically the performance of PGA Tour players.
It answers a much more valuable question: “Given where this shot started, how much better or worse was my result compared to a pro?” By doing this for every shot, you get a clear, unbiased verdict on what parts of your game are genuinely helping you and which are costing you strokes.
The Four Pillars of Strokes Gained
Strokes Gained analysis breaks the game down into four fundamental categories. This helps you pinpoint exactly where you’re winning or losing against your benchmark.
- Strokes Gained: Off-the-Tee (SG:OTT): This tracks all your shots from the tee on par 4s and par 5s. It doesn’t just measure whether you hit the fairway, it measures how much your drive improved your position for the next shot. A 300-yard drive into the rough might be worse than a 270-yard drive in the fairway, and SG:OTT will show you that.
- Strokes Gained: Approach-the-Green (SG:APP): This includes all shots that are not from the tee on a par 4 or 5 and are intended to land on the green. This is your iron and wedge play. It’s widely considered the most important statistic for scoring, as it determines how close your birdie putts will be.
- Strokes Gained: Around-the-Green (SG:ARG): This category covers your short game - any shot within about 50 yards of the green, such as chipping, pitching, and bunker play. It measures your ability to get up and down.
- Strokes Gained: Putting (SG:P): This one is simple: it’s all your action once the ball is on the putting surface. It evaluates how many putts you took compared to how many a pro would be expected to take from that same distance.
How the Calculation Works (It's Simpler Than You Think)
The math behind Strokes Gained might seem intimidating, but the core concept is straightforward. It’s all based on a massive database of shots, which tells us the average number of strokes it takes a PGA Tour pro to hole out from any given distance and lie (fairway, rough, sand, etc.).
Let's walk through an example. You have 150 yards to the hole from the middle of the fairway.
According to the PGA Tour benchmark, the average number of strokes it takes to get in the hole from there is 2.8. That’s your starting value.
You hit a great 8-iron that stops 10 feet from the cup. The Tour average to hole out from 10 feet is 1.5 strokes. That’s your ending value.
Now, we use this simple formula:
Strokes Gained = Starting Value - Ending Value - 1 (for the one shot you just hit)
For your approach shot, the calculation is:
2.8 - 1.5 - 1 = +0.3
In that single swing, you gained three-tenths of a stroke on a PGA Tour pro. Great job!
Now, let's look at the putt. You’re at 10 feet, and the average strokes to hole out is 1.5. You make the putt in one stroke. The "ending value" is 0 because the ball is in the hole. So the calculation is:
1.5 - 0 - 1 = +0.5
You gained half a stroke with that putt. Congratulations!
But what if you miss and have a 2-foot tap-in? You took two shots to get in the hole. The calculation would be:
1.5 - 0 - 2 = -0.5
You lost half a stroke to the pros on that 10-foot putt. By applying this logic to every single shot over a round, you get a precise measurement of your entire game, broken down by category.
Three Ways You Can Start Tracking Your Strokes Gained
Thinking like a pro is one thing, but how do you actually get this data for your own game? You have a few options, ranging from fully automated to simple and manual.
Method 1: Use a Golf App or GPS Device (The Easy Way)
The most convenient way to track Strokes Gained is with an automated system. Companies like Arccos Caddie and Shot Scope offer smart sensors that you attach to the end of your grips. Once paired with a smartphone app or a GPS watch, these systems register every shot you hit on the course automatically.
How it works:
- You play your round just like you normally would. The sensors and GPS technology collect your shot data (club used, start and end location) without you having to do much.
- After your round, the app processes all this information and crunches the numbers for you.
- You get a beautiful dashboard that shows you exactly how many strokes you gained or lost in all four categories (and others, like specific distance ranges).
The Pro: It’s virtually effortless on your part. You just play golf and get powerful insights.
The Con: These systems come with an upfront cost and sometimes an annual subscription fee.
Method 2: The DIY Spreadsheet (For the Data Fanatic)
If you enjoy numbers and want full control over your data without paying for a subscription, you can build your own Strokes Gained calculator in a program like Google Sheets or Microsoft Excel.
Step-by-step instructions:
- Gather Your Data: This is the hard part. During your round, you need to be diligent about recording where every shot starts and ends. You’ll need the distance to the pin and the lie (Tee, Fairway, Rough, Sand, Recovery, Green) for every shot. You can use a GPS watch or a rangefinder to get distances and make notes on your scorecard or in a notepad.
- Find a Baseline Chart: You need the benchmark data. A quick search for "Strokes Gained baseline data chart" will give you tables showing the average strokes to hole out for different lies and distances. You’ll use this as your reference data.
- Set up Your Spreadsheet: Create a sheet with the following columns: Hole, Shot Number, Start Distance, Start Lie, End Distance, End Lie.
- Execute the Formula: Add more columns for "Start SG Value" and "End SG Value." Use a `VLOOKUP` or `INDEX/MATCH` function to pull the PGA Tour average from your baseline data chart for the start and end of each shot. Finally, create a "Strokes Gained" column and apply the formula: `Start SG Value - End SG Value - 1`.
Here’s a simplified look at what a function in a cell might look like in Excel or Google Sheets:
=VLOOKUP(Start_Distance, Baseline_Table, 2, TRUE) - VLOOKUP(End_Distance, Baseline_Table, 2, TRUE) - 1
This method requires effort, but it's incredibly rewarding and gives you a deep understanding of the engine behind the stats.
Method 3: "Relative" SG Thinking (The On-the-Fly Approach)
Don't want to mess with apps or spreadsheets? You can still benefit from the mindset. Instead of formal tracking, you can learn a few key benchmarks and compare yourself to them during your round. This helps with strategy and post-round analysis.
Here are a few benchmarks to remember:
- From 8 feet, a PGA Tour pro makes the putt 50% of the time. So, their average is 1.5 strokes. If you make it, you did great! If you two-putt, that’s about average. Three-putting? You lost strokes.
- From 100 yards in the fairway, a pro’s average proximity to the hole is about 15-18 feet. How does your wedge play stack up? Are you regularly hitting it inside that range?
- A tour pro gets up and down from a greenside bunker about 50% of the time. You can think of their "average score" from the sand as a 2.5. If you get up and down, your score for that situation is 2. You "gained" half a shot. If you take 3 to get down, you lost half a shot.
Thinking this way frames your performance in a more realistic light. It pushes you to focus on the shots that truly make a difference in your scoring, rather than obsessing over things like hitting every fairway.
