Every golfer thinks they know which club is costing them the most shots. Most will point to the driver that sprays two fairways over or the 60-degree wedge that gets skulled across the green. But when we look at the numbers, the reality is a little different.
We analyzed the data to identify which clubs are statistically costing golfers the most strokes. Shot Scope gave us access to Strokes Gained data broken down by handicap and while I’d love to say the results are shocking, they’re actually pretty much what you’d expect. Still, seeing the numbers paints a clear picture of where golfers of all skill levels lose the most ground.
25 handicap
For a 25-handicap golfer, the 5-iron is the biggest stroke loser in the bag. On average, it costs –0.373 strokes per swing compared to a scratch player. That’s a steep penalty for a single shot.
Long irons demand swing speed, precise contact and tight dispersion, all things higher handicaps struggle with the most.
By comparison, the putter and gap wedge are far more efficient, costing fewer strokes per attempt and serving as reliable tools to keep scores manageable.
| Category | Club | Avg SG per Shot (vs Scratch) |
|---|---|---|
| Costs the Most | 5-Iron | –0.373 |
| Saves the Most | Putter | –0.137 |
| Next Best | Gap Wedge | –0.254 |
20 handicap
When your handicap drops to a 20, the 5-iron continues to drag scores down, losing –0.328 strokes per swing. While not quite as severe as for 25 handicaps, it still represents a high-risk club. For most golfers at this level, replacing the 5-iron with a hybrid or higher-lofted fairway wood would likely save strokes.
The putter remains the most efficient club, with the gap wedge following closely behind.
| Category | Club | Avg SG per Shot (vs Scratch) |
|---|---|---|
| Costs the Most | 5-Iron | –0.328 |
| Saves the Most | Putter | –0.115 |
| Next Best | Gap Wedge | –0.216 |
15 handicap
For mid-handicap golfers, the same trend holds. The 5-iron costs –0.276 strokes per swing. While ball striking improves at this level, the long iron still demands precision that most players can’t consistently deliver.
The gap and putter still save the most strokes.
| Category | Club | Avg SG per Shot (vs Scratch) |
|---|---|---|
| Costs the Most | 5-Iron | –0.276 |
| Saves the Most | Putter | –0.092 |
| Next Best | Gap Wedge | –0.178 |
10 handicap
Take a wild guess at which club is still costing golfers the most strokes?
It’s the 5-iron, costing –0.205 strokes per swing. At this level, players are more consistent, but the punishment for even small misses with a long iron keeps the numbers negative.
What changes is the “best” category: the driver enters the conversation alongside the putter, reflecting improved ball speed, strike quality and dispersion off the tee.
| Category | Club | Avg SG per Shot (vs Scratch) |
|---|---|---|
| Costs the Most | 5-Iron | –0.205 |
| Saves the Most | Putter | –0.067 |
| Next Best | Driver | –0.121 |
5 handicap
Even for 5-handicap golfers, the 5-iron remains the weakest performer at –0.136 strokes per swing. The gap in Strokes Gained compared to that of a scratch player is much smaller at this level. Here is where we see that skilled players are handling their 5-iron much better, but it’s still not a club that gains strokes.
At this level, the putter remains the most efficient club and the 3-wood joins as another strong performer.
| Category | Club | Avg SG per Shot (vs Scratch) |
|---|---|---|
| Costs the Most | 5-Iron | –0.136 |
| Saves the Most | Putter | –0.040 |
| Next Best | 3-Wood | –0.052 |
Scratch Golfers
Even scratch golfers aren’t immune to the struggles of the 5-iron. It still averages –0.062 strokes per swing compared to the scratch baseline (yes, even the best of the best lose ground with it). The difference is tiny but it proves that the 5-iron remains unforgiving no matter the skill level.
What’s most interesting is that, for scratch players, the driver and 3-wood actually produce positive StrokesGgained, making them the only group where the long game truly becomes a scoring tool rather than a liability.
| Category | Club | Avg SG per Shot (vs Scratch) |
|---|---|---|
| Costs the Most | 5-Iron | –0.062 |
| Saves the Most | Driver | +0.027 |
| Next Best | 3-Wood | –0.024 |
Final takeaway
Across every handicap, the 5-iron consistently costs golfers the most strokes. The losses shrink as skill improves but even scratch players can’t turn it into a net positive. Meanwhile, putters dominate as the most efficient club for nearly every group, with drivers and 3-woods becoming increasingly valuable as skill levels rise.
Bottom line: if you’re looking to save strokes, ditch the 5-iron. Swap it for a hybrid or higher-lofted fairway wood.

There are A LOT of good points in the discussion referring to how many times a round a club is used. It begs the question of how many rounds are included in that stat. Comparing to a 0HCP in 2020 my 3I and 4I were -0.2 strokes for the season, in 2021 my 6I was -0.3, in 2022 my 3I jumped to -0.3 SG,in 2023 my 4I improved to +.03 SG the dropped back to -0.2 in 2024, but is even for this season yet my 6I dropped to -0.25. I believe a lot of this has to do with frequency of use. When we shift to compare to my own group, 5HCP everything changes. In 2020 my 3I was the worst iron at -0.1SG, in 2022 ONLY my 5I and 50 deg were +SG, in 2022 9I down were all negative SG, in 2023 even # irons were all +SG and neg # irons were all -SG, 2024 iron performance was grouped in pairs, 3-4I neg, 5-6I pos, etc. down the line. This year, 2025, my 6I and 56 degree are the only -SG irons. Every other iron is under 0.05+/-.
