Understanding the Strokes Gained Calculator
The strokes gained calculator is a powerful tool used in golf analytics to measure a player’s performance against a benchmark, typically the average performance of professional golfers (like those on the PGA Tour). It tells you how many strokes you gained or lost compared to the benchmark in different aspects of your game: Tee-to-Green and Putting. A positive number means you performed better than the benchmark, while a negative number means you performed worse.
What is Strokes Gained?
Strokes Gained is a statistical measure in golf that compares a player’s performance on every shot to a baseline or benchmark (e.g., PGA Tour average). It quantifies exactly how much better or worse a player’s shot was compared to the average, measured in strokes. The concept was developed by Professor Mark Broadie of Columbia Business School and has been adopted by the PGA Tour and golf analysts worldwide.
Instead of just looking at fairways hit or greens in regulation, strokes gained tells you the value of each shot. For example, if the average number of strokes to hole out from 150 yards in the fairway is 2.99, and a player holes out in 2 strokes, they gained 0.99 strokes on that shot relative to the average.
Who should use it?
Any golfer serious about improving their game can benefit from understanding and using strokes gained analysis, not just professionals. Our strokes gained calculator helps you pinpoint weaknesses and strengths in your game by comparing your performance to a high-level benchmark across different situations (driving, approach shots, putting).
Common Misconceptions
- It’s only for pros: While the benchmarks are often based on pro data, the concept of comparing your performance to a consistent baseline is valuable for all skill levels. You can even compare against your own past performance or a scratch golfer benchmark if data is available.
- It’s too complicated: The core idea is simple – comparing your strokes taken to an average. Our strokes gained calculator simplifies the process for individual shots or holes.
- You need expensive software: While detailed round-by-round analysis often uses specialized software, our calculator gives you a taste of how it works for specific scenarios.
Strokes Gained Calculator Formula and Mathematical Explanation
The strokes gained calculator breaks down performance into two main categories for a given hole or series of shots leading to the green and then on the green:
- Strokes Gained Tee-to-Green (SG T2G): Measures performance on all shots from the tee until the ball is on the green.
- Strokes Gained Putting (SG P): Measures performance on the green.
The formulas used by our strokes gained calculator are:
SG Tee-to-Green = Benchmark Strokes from Start - Benchmark Putts from First Putt Distance - Strokes to Reach Green
SG Putting = Benchmark Putts from First Putt Distance - Actual Putts Taken
Total Strokes Gained = SG Tee-to-Green + SG Putting
Alternatively, Total Strokes Gained can also be calculated as: Total Strokes Gained = Benchmark Strokes from Start - Total Strokes Taken (where Total Strokes Taken = Strokes to Reach Green + Actual Putts Taken, assuming you don’t hole out from off the green).
Variable Explanations
| Variable | Meaning | Unit | Typical Range |
|---|---|---|---|
| Benchmark Strokes from Start | Average strokes to hole out from the starting distance and lie. | Strokes | 1.0 – 5.5 |
| Benchmark Putts from First Putt | Average putts to hole out from the first putt distance on the green. | Strokes | 1.0 – 2.5 |
| Strokes to Reach Green | Number of shots taken from the start until the ball is on the green. | Strokes | 0 – 6 |
| Actual Putts Taken | Number of putts taken on the green. | Strokes | 0 – 4 |
Practical Examples (Real-World Use Cases)
Example 1: Good Approach, Average Putting
A player starts on a 450-yard par 4 (Tee). The benchmark strokes from there are 4.10. They hit their drive and then their approach shot, taking 2 strokes to reach the green, leaving a 10-foot putt. The benchmark putts from 10 feet are 1.60. The player takes 2 putts.
- Start Distance: 450 yards, Lie: Tee, Benchmark Start: 4.10
- Strokes to Green: 2
- First Putt Distance: 10 feet, Benchmark Putts: 1.60
- Putts Taken: 2
Using the strokes gained calculator:
SG Tee-to-Green = 4.10 – 1.60 – 2 = +0.50 strokes
SG Putting = 1.60 – 2 = -0.40 strokes
Total SG = 0.50 + (-0.40) = +0.10 strokes. The player gained 0.1 strokes overall compared to the benchmark, with a strong tee-to-green performance but slightly below-average putting.
Example 2: Poor Tee Shot, Great Putting
A player starts on a 180-yard par 3 (Tee). Benchmark strokes are 3.05. They hit a poor tee shot into the rough, then take 1 more shot to get on the green, leaving a 30-foot putt. Benchmark putts from 30 feet are 2.00. The player makes the 30-foot putt in 1 go.
- Start Distance: 180 yards, Lie: Tee, Benchmark Start: 3.05
- Strokes to Green: 2 (Tee shot + shot from rough)
- First Putt Distance: 30 feet, Benchmark Putts: 2.00
- Putts Taken: 1
Using the strokes gained calculator:
SG Tee-to-Green = 3.05 – 2.00 – 2 = -0.95 strokes
SG Putting = 2.00 – 1 = +1.00 strokes
Total SG = -0.95 + 1.00 = +0.05 strokes. Despite a poor tee-to-green performance, exceptional putting saved the day, resulting in a small overall gain.

Key Factors That Affect Strokes Gained Results
- Benchmark Data Accuracy: The quality of your analysis depends heavily on the accuracy and relevance of the benchmark data used. PGA Tour averages are common, but you could use scratch golfer data too.
- Honest Input: Accurately recording your distances, lies, and strokes taken is crucial for meaningful results from the strokes gained calculator.
- Shot Location Data: More advanced strokes gained analysis considers the precise location of each shot, not just distance and general lie.
- Course Conditions: Wind, rain, and course setup can influence scores and thus how your performance compares to a static benchmark.
- Lie Difficulty: “Rough” can vary greatly. More granular data (light rough, heavy rough) improves accuracy.
- Putt Distance Accuracy: Pacing off or estimating putt distances needs to be as accurate as possible for reliable SG Putting figures.
Frequently Asked Questions (FAQ)
- What is a good Strokes Gained value?
- Any positive value is good, meaning you performed better than the benchmark. Top professional golfers often have positive total strokes gained per round, while amateurs will more likely have negative values when compared to pros.
- How is the benchmark data derived?
- Benchmark data, like that used by the PGA Tour, is collected by tracking the starting and ending position of every shot taken by players over many rounds and calculating the average strokes to hole out from every conceivable position.
- Can I use this strokes gained calculator for practice rounds?
- Yes, it’s a great way to evaluate your performance in practice under course-like conditions.
- What if I hole out from off the green?
- If you hole out before reaching the green, set “Strokes to Green” to the number of shots taken, “First Putt Distance” and “Benchmark Putts” to 0, and “Putts Taken” to 0. Total SG would be Benchmark Strokes from Start – Strokes to Green.
- Where can I find more detailed benchmark data?
- Websites and apps dedicated to golf analytics, like those from Mark Broadie or the PGA Tour, often have more detailed data, sometimes requiring a subscription. The table above provides basic estimates.
- How does Strokes Gained differ from traditional stats like GIR or Fairways Hit?
- Traditional stats are binary (you hit it or you didn’t) and don’t weigh the quality of the shot. Hitting a fairway 10 yards short of the green is very different from hitting it 150 yards out. Strokes gained quantifies the value of every shot. Our golf stats page explains more.
- Can I compare my strokes gained to my handicap?
- While both relate to your skill, they measure different things. Handicap compares you to the course and other amateurs, while strokes gained often compares you to pros. You can find our golf handicap calculator here.
- Does the strokes gained calculator account for different clubs?
- Not directly. It focuses on the start and end position of the ball, regardless of the club used, although club choice influences those positions. Some advanced tools look at driving accuracy with specific clubs.
