Comprehensive Guide: How to Calculate Strokes Gained in Golf

Strokes Gained is a revolutionary golf statistic that measures a player’s performance relative to the field or a specific benchmark (like a scratch golfer). Developed by Professor Mark Broadie from Columbia Business School, this metric has become the gold standard for analyzing golf performance at all levels—from PGA Tour professionals to weekend amateurs.

What Is Strokes Gained?

Strokes Gained compares the number of strokes a player takes to complete a hole (or shot) against the statistical average for that same situation. It answers the question: “How many strokes did this player gain (or lose) compared to an average player from this exact position?”

The beauty of Strokes Gained is that it accounts for every shot in a round—drives, approach shots, short game, and putting—allowing golfers to pinpoint exactly where they’re gaining or losing strokes.

Key Benefits of Strokes Gained

  • Precision: Measures performance for each shot type independently.
  • Comparability: Allows direct comparison between players of different skill levels.
  • Actionable: Identifies specific areas for improvement (e.g., “You lose 1.2 strokes per round on approach shots from 150-175 yards”).
  • Tour-Proven: Used by 100% of PGA Tour players and their coaches.

Strokes Gained vs. Traditional Stats

  • Fairways Hit: Doesn’t account for distance or lie quality.
  • Greens in Regulation: Ignores proximity to the hole.
  • Putts per Round: Doesn’t consider starting distance.
  • Strokes Gained: Accounts for all variables—distance, lie, difficulty, and outcome.

How Strokes Gained Is Calculated

The formula for Strokes Gained is:

Strokes Gained = (Average strokes to hole out from starting position) – (Actual strokes taken to hole out) – (Average strokes to hole out from resulting position)

Let’s break this down with an example:

  1. Starting Position: You’re 160 yards from the hole in the fairway. The PGA Tour average strokes to hole out from this position is 2.85.
  2. Your Shot: You hit your approach to 15 feet. The Tour average strokes to hole out from 15 feet is 1.85.
  3. Actual Strokes Taken: You take 2 putts to finish the hole (1 stroke for the approach + 2 putts = 3 total).
  4. Calculation:
    • Expected strokes from 160 yards: 2.85
    • Expected strokes from 15 feet: 1.85
    • Actual strokes taken: 3
    • Strokes Gained: 2.85 – (3 – 1.85) = +1.70

In this case, you gained 1.70 strokes on the field with that approach shot—a fantastic result!

Strokes Gained by Category

Strokes Gained is typically broken into four key categories:

Category Description PGA Tour Average (2023) 10-Handicap Average
Off the Tee Measures driving distance and accuracy. Longer drives that stay in play are rewarded. +0.25 strokes/round -0.80 strokes/round
Approach the Green Shots from >50 yards until the ball is on the green. Proximity to hole is critical. +1.10 strokes/round -1.50 strokes/round
Around the Green Shots from ≤50 yards (not on the green). Includes chips, pitches, and bunker shots. +0.40 strokes/round -0.90 strokes/round
Putting All strokes on the green. Accounts for starting distance (3-ft putts vs. 40-ft putts). +0.30 strokes/round -0.70 strokes/round

Note: Positive numbers indicate strokes gained on the field; negative numbers indicate strokes lost.

How to Use Strokes Gained to Improve Your Game

Here’s a step-by-step plan to leverage Strokes Gained for rapid improvement:

  1. Track Your Shots: Use a golf GPS app (like Arccos or Shot Scope) or a simple notebook to record:
    • Starting distance and lie for every shot
    • Resulting distance and lie
    • Strokes taken to hole out
  2. Calculate Your Averages: After 5-10 rounds, compute your Strokes Gained in each category. Most GPS systems do this automatically.
  3. Identify Weaknesses: Look for categories where you’re losing >0.5 strokes/round compared to your handicap benchmark.
  4. Prioritize Practice: Allocate 70% of your practice time to your biggest weakness. For example:
    • If you’re losing 1.2 strokes/round on approach shots, focus on wedge play and iron accuracy.
    • If putting is your weakness, practice lag putting and 5-10 footers.
  5. Set Measurable Goals: Aim to improve by 0.2 strokes/round in your weakest category over 3 months.
  6. Reassess: After 10 rounds, recalculate your Strokes Gained to measure progress.

Common Strokes Gained Mistakes to Avoid

❌ Mistake: Ignoring Lie Type

Strokes Gained varies dramatically by lie. A 150-yard shot from the rough is 0.5 strokes harder than from the fairway. Always record your lie!

❌ Mistake: Small Sample Size

Don’t draw conclusions from 1-2 rounds. You need at least 5 rounds (or 50 shots in a category) for meaningful data.

❌ Mistake: Comparing to the Wrong Benchmark

A 20-handicap shouldn’t compare to PGA Tour averages. Use handicap-specific benchmarks (see table below).

Strokes Gained Benchmarks by Handicap (Per Round)
Handicap Off the Tee Approach Around Green Putting Total
Scratch (0) -0.10 -0.30 -0.20 -0.10 -0.70
5 -0.30 -0.70 -0.40 -0.30 -1.70
10 -0.50 -1.10 -0.60 -0.50 -2.70
15 -0.80 -1.50 -0.90 -0.70 -3.90
20 -1.20 -2.00 -1.30 -1.00 -5.50
25 -1.70 -2.60 -1.80 -1.40 -7.50

Advanced Strokes Gained Strategies

Once you’ve mastered the basics, try these pro-level techniques:

  1. Course Strategy Optimization: Use Strokes Gained data to plan your approach to each hole. For example:
    • If you gain 0.3 strokes/round by laying up on par-5s, do it—even if it “feels” conservative.
    • If you lose 0.4 strokes/round going for par-3 pins, aim for the fat part of the green.
  2. Equipment Fitting: Bring your Strokes Gained data to a club fitting. If you’re losing strokes on 150-yard approaches, a properly fit 7-iron could be worth 0.5 strokes/round.
  3. Mental Game: Track “Strokes Gained: Mental” by noting how your performance changes under pressure. Many amateurs lose 1-2 strokes/round due to tension on critical shots.
  4. Practice Games: Design practice games that mimic real-course Strokes Gained scenarios. Example:
    • Place 10 balls at 100 yards and try to average <15 feet from the hole (Tour average is 14 feet).

Strokes Gained in Professional Golf

On the PGA Tour, Strokes Gained is the only statistic that correlates strongly with earnings. Here’s how the top players dominate:

  • Rory McIlroy: Gains +1.2 strokes/round off the tee (2023 average). His combination of distance (320+ yards) and accuracy (58% fairways) is unmatched.
  • Scottie Scheffler: Leads the Tour in Strokes Gained: Approach (+1.45 in 2023). His ball-striking is so precise that he averages 12 feet from the hole on approaches—3 feet closer than the Tour average.
  • Viktor Hovland: Gains +0.8 strokes/round putting, thanks to his ability to hole 20% of putts from 15-20 feet (Tour average is 12%).
  • Collin Morikawa: His iron play is elite—he gains +1.3 strokes/round on approaches, with 68% of his shots finishing inside 15 feet from 150-175 yards.

Even small improvements add up. In 2023, the difference between the 50th and 1st ranked player in Strokes Gained: Total was just +1.2 strokes/round—yet that translated to $5 million in earnings!

Frequently Asked Questions

How many rounds do I need to track for accurate Strokes Gained data?

For meaningful insights, track at least 10 rounds (or 100 shots in a specific category). The more data, the better—pro golfers often analyze 50+ rounds to identify trends.

Can Strokes Gained help me choose clubs?

Absolutely! If your Strokes Gained data shows you’re losing strokes on 50-yard shots, it might be time to add a 52° wedge or practice your partial swings. Similarly, if you’re losing strokes on 180-yard approaches, a hybrid might be a better play than a long iron.

How does course difficulty affect Strokes Gained?

Strokes Gained adjusts for course difficulty automatically. A 150-yard shot is harder from the rough on a U.S. Open setup than from the fairway at your local muni. The metric accounts for these differences using historical data from thousands of rounds.
