Golf Strokes Gained Calculator

Strokes Gained is a statistical method that measures how many strokes you gain or lose relative to a benchmark player from any given situation on the golf course. A positive value means you performed better than the benchmark; a negative value means you lost strokes compared to them. It was developed using PGA Tour ShotLink data and is now widely used at all levels of the game.

Strokes Gained compares the expected number of strokes needed to hole out from your starting position versus your finishing position, then subtracts 1 (for the shot played). This calculator uses your round statistics — fairways hit, GIR, proximity, scrambling, and putting — and compares them to benchmark averages for the selected player profile to estimate your strokes gained in each category.

The four standard categories are: SG: Driving (tee shots on par 4s and 5s), SG: Approach (shots from outside 100 yards targeting the green), SG: Short Game (shots from within 100 yards excluding putts, including chipping and bunker play), and SG: Putting (all strokes on the putting surface). Together they account for every shot in a round.

You can compare yourself against a Tour Pro, Scratch golfer, 5 Handicap, 10 Handicap, 15 Handicap, or 20 Handicap. Each benchmark represents the average statistical performance for that player level, including typical putts per round, GIR rates, driving distances, and scrambling percentages. Choosing a benchmark close to your own level gives the most meaningful feedback.

Traditional stats can be misleading in isolation — for example, a low putt count might simply mean you're missing a lot of greens and chipping close, not that you're a great putter. Strokes Gained accounts for context, measuring each shot relative to what an average golfer would score from the same position. This makes it a much more reliable diagnostic tool for identifying strengths and weaknesses.

This calculator uses your summary round statistics (GIR, putts, scrambling, etc.) rather than shot-by-shot tracking, so it provides a reliable approximation rather than exact shot-level data. Dedicated apps like Arccos, Shot Scope, or Golf Pad GPS track every shot's location and compute precise SG values. This tool is best used for quick round analysis and trend tracking without the need for GPS hardware.

The main limitation is that summary statistics (like total putts or GIR) can mask shot-by-shot variation. For example, two players with 30 putts may have very different putting performances depending on their average putt length. Shot-tracking apps remove this ambiguity. Additionally, benchmark values are averages — your course difficulty, playing conditions, and pin positions all affect the true strokes gained values.

Focus your practice on the category where you're losing the most strokes relative to your benchmark. If SG: Approach is strongly negative, prioritise iron play and course management into greens. If SG: Putting is the weakness, work on distance control and short-putt consistency. Track your SG values over multiple rounds to identify persistent patterns rather than reacting to a single outlier round.
