Strokes to Hole Out Reference Data
This table provides the hypothetical average number of strokes a PGA Tour player would take to hole out from various distances. This data is used by the Strokes Gained Calculator for its calculations. Values are interpolated for distances not explicitly listed.
| Shot Type | Distance Range | Unit | Average Strokes to Hole Out |
|---|---|---|---|
| Putting | 0 - 100 | Feet | 1.00 - 2.80 |
| Around the Green | 5 - 50 | Yards | 2.60 - 3.25 |
| Approach | 50 - 250 | Yards | 3.00 - 3.80 |
| Tee Shot (distance remaining) | 250 - 600 | Yards | 3.90 - 4.60 |
Note: These values are illustrative and simplified for the purpose of this calculator. Real PGA Tour data is more granular and dynamic.
Visualizing Strokes Gained Baselines
This chart illustrates the general trend of how average strokes to hole out decrease as a player gets closer to the hole. It helps visualize the baseline data used in Strokes Gained calculations.
What is Strokes Gained?
Strokes Gained is a revolutionary golf performance metric that quantifies a player's performance relative to the average of other professional golfers (typically the PGA Tour average). Unlike traditional statistics like fairways hit or greens in regulation, which only tell you if a target was hit, Strokes Gained tells you how good that shot was by comparing it to a baseline expectation.
It answers the question: "Did this shot save strokes compared to an average professional from the same starting position?" This powerful golf analytics tool was developed by Mark Broadie, a professor at Columbia Business School, and has transformed how golfers and coaches analyze performance.
Who Should Use It: Any golfer looking to truly understand their game beyond just their final score. From aspiring professionals to dedicated amateurs, understanding your Strokes Gained categories (Off-the-Tee, Approach, Around-the-Green, Putting) can pinpoint exact areas for improvement. Coaches use it extensively for golf performance metrics and player development.
Common Misunderstandings:
- It's not just about total score: A low score doesn't always mean efficient play, and vice-versa. Strokes Gained focuses on shot-by-shot efficiency.
- Relative, not absolute skill: It measures performance relative to a benchmark, not an absolute skill level. A player with +0.5 Strokes Gained in putting is half a stroke better than the average PGA Tour player for the putts they hit.
- Unit Confusion: The "strokes" gained is a unitless measure representing the difference in expected strokes, not literally how many strokes were saved on a single shot. Distances are crucial and must be consistently handled in yards or feet.
How is Strokes Gained Calculated? The Formula Explained
The core principle of how is Strokes Gained calculated lies in comparing the expected number of strokes a PGA Tour player would take to hole out from a given position, before and after your shot, and then accounting for the actual strokes you took.
The formula for a single shot is:
Strokes Gained (SG) = (Average Strokes to Hole Out from Start Position) - (Average Strokes to Hole Out from End Position) - (Strokes Taken for Shot)
Let's break down each variable:
| Variable | Meaning | Unit | Typical Range |
|---|---|---|---|
Avg_Strokes_Start |
The average number of strokes a PGA Tour player takes to get the ball into the hole from your starting position before the shot. | Strokes (unitless) | 1.00 (in hole) to ~5.00 (long par 5 tee shot) |
Avg_Strokes_End |
The average number of strokes a PGA Tour player takes to get the ball into the hole from your ending position after the shot. | Strokes (unitless) | 1.00 (in hole) to ~5.00 (long par 5 tee shot) |
Strokes_Taken |
The actual number of strokes you took to execute the shot. | Strokes (count) | 1 to 5 (for a single shot) |
For example, if a PGA Tour player averages 3.0 strokes to hole out from 150 yards, and your shot from 150 yards lands 20 feet from the hole (where the average is 2.0 strokes to hole out), and you took 1 stroke:
SG = 3.0 (Start) - 2.0 (End) - 1 (Taken) = 0.0
In this scenario, you performed exactly at the PGA Tour average. If your shot landed 10 feet from the hole (Avg 1.8 strokes), then SG = 3.0 - 1.8 - 1 = +0.2, meaning you gained 0.2 strokes on the field. This detailed golf improvement metric provides crucial insights.
Practical Examples of Strokes Gained Calculation
Let's walk through a few scenarios to illustrate how is Strokes Gained calculated using our hypothetical PGA Tour average data:
Example 1: Excellent Approach Shot
- Inputs:
- Shot Type: Approach Shot
- Starting Distance to Hole: 150 Yards
- Ending Distance to Hole: 6 Feet
- Strokes Taken: 1
- Calculation:
- Avg Strokes (Start, 150 yds): ~3.40
- Avg Strokes (End, 6 ft): ~1.45
- Strokes Gained = 3.40 - 1.45 - 1 = +0.95
- Result: You gained 0.95 strokes on the field with that approach shot. This is an exceptional shot!
Example 2: Missed Short Putt
- Inputs:
- Shot Type: Putting
- Starting Distance to Hole: 6 Feet
- Ending Distance to Hole: 2 Feet
- Strokes Taken: 1
- Calculation:
- Avg Strokes (Start, 6 ft): ~1.45
- Avg Strokes (End, 2 ft): ~1.10 (interpolated)
- Strokes Gained = 1.45 - 1.10 - 1 = -0.65
- Result: You lost 0.65 strokes on the field with that putt. This indicates a significant area for putting analysis and improvement.
Example 3: Solid Tee Shot
- Inputs:
- Shot Type: Tee Shot
- Starting Distance to Hole: 450 Yards (representing a par 5 tee)
- Ending Distance to Hole: 200 Yards
- Strokes Taken: 1
- Calculation:
- Avg Strokes (Start, 450 yds): ~4.60
- Avg Strokes (End, 200 yds): ~3.60
- Strokes Gained = 4.60 - 3.60 - 1 = 0.00
- Result: You performed at the PGA Tour average for that tee shot. A good driving accuracy shot.

Key Factors That Affect Strokes Gained
Understanding how is Strokes Gained calculated allows you to identify specific areas of your game that contribute positively or negatively to your overall score. Here are key factors that significantly influence your Strokes Gained performance:
- Accuracy Off-the-Tee: Hitting fairways, especially long ones, reduces the average strokes needed for your subsequent approach shot. Poor driving accuracy often leads to lost strokes.
- Approach Shot Efficiency: The ability to hit greens and leave yourself with shorter putts directly translates to higher Strokes Gained: Approach numbers. This is a critical component of approach shot efficiency.
- Putting Performance: This is often the most scrutinized Strokes Gained category. Consistently holing short putts, avoiding three-putts, and lagging long putts close are huge contributors to positive Strokes Gained: Putting.
- Short Game Skill (Around-the-Green): Excellent chipping, pitching, and bunker play from around the green can turn potential bogeys into pars or even birdies, saving crucial strokes.
- Course Management & Decision Making: Smart choices about club selection, target lines, and risk assessment can prevent costly mistakes and indirectly improve Strokes Gained by putting you in better positions.
- Mental Fortitude: Performing well under pressure, especially on crucial shots, helps maintain or improve Strokes Gained. A strong mental game minimizes errors that lead to lost strokes.
- Physical Fitness: A good golf fitness routine can lead to increased clubhead speed and better control, improving distances and accuracy across all categories.
Frequently Asked Questions About Strokes Gained
Q: What is a good Strokes Gained number?
A: For a single shot, a positive Strokes Gained number is good, meaning you outperformed the average PGA Tour player. Over an entire round, PGA Tour winners often average +2 to +4 Strokes Gained per round, meaning they gained 2-4 strokes on the field over 18 holes.
Q: How do you calculate Strokes Gained for an entire round?
A: To calculate for an entire round, you sum the Strokes Gained values for every single shot. The total is then compared to the baseline of 0 (average PGA Tour performance for that round). Most professional shot tracking systems do this automatically.
Q: What are the different Strokes Gained categories?
A: Strokes Gained is typically broken down into four main categories: Off-the-Tee (drives), Approach (shots from fairway/rough to green), Around-the-Green (chips, pitches, bunkers), and Putting. This granular breakdown is crucial for targeted golf improvement.
Q: Why is Strokes Gained better than traditional golf stats?
A: Traditional stats like "fairways hit" don't tell you the quality of the miss or how easy the next shot was. Strokes Gained provides context by comparing every shot to a professional baseline, giving a more accurate picture of a player's true performance and where they are gaining or losing strokes.
Q: Does this calculator use real PGA Tour data?
A: This calculator uses hypothetical, simplified data that approximates PGA Tour averages for illustrative purposes. Real PGA Tour data is more complex, dynamic, and includes a wider range of distances and situations. It's a great tool for understanding the calculation but not for precise professional analysis.
Q: How do I convert between yards and feet for distances?
A: There are 3 feet in 1 yard. If you have yards, multiply by 3 to get feet. If you have feet, divide by 3 to get yards. Our calculator's unit selectors handle this conversion internally.
Q: Can I use this calculator for non-PGA Tour players?
A: Absolutely! While the baseline is PGA Tour average, the calculation method is universal. It helps any golfer understand their performance relative to a high standard, highlighting areas where they might be losing more strokes compared to a pro. This helps with personalized golf performance metrics.
Q: What if my shot goes out of bounds or into a hazard?
A: This calculator is designed for "live ball" scenarios where you have a clear starting and ending distance to the hole. Shots with penalties (out of bounds, water hazard) complicate the Strokes Gained calculation significantly, as they involve re-hitting and adding penalty strokes. Our simplified model doesn't directly account for penalties in the distance inputs, but you would factor in the additional strokes taken for the penalty in the "Strokes Taken" field.
