The Golf Club That Costs You The Most Strokes (Broken Down By Handicap)
For a golfer with a 25 handicap, the 5-iron is the most significant stroke loser in their bag. On average, using a 5-iron costs –0.373 strokes per swing compared to a scratch player. That's a steep penalty for a single shot. Long irons require swing speed, precise contact, and tight dispersion, all of which higher handicappers often struggle to achieve. By comparison, the putter and gap wedge are much more efficient. They cost fewer strokes per attempt and are reliable tools for keeping scores manageable. When the handicap drops to 20, the 5-iron continues to drag scores down, losing –0.328 strokes per swing. Although it's not as severe as for 25 handicaps, it still represents a high-risk club. Most golfers at this level would likely save strokes by replacing the 5-iron with a hybrid or higher-lofted fairway wood. The putter remains the most efficient club, closely followed by the gap wedge. For mid-handicap golfers (15 handicap), the trend continues—the 5-iron costs –0.276 strokes per swing. Although ball striking improves at this level, long irons still demand a precision that many players cannot consistently deliver. The gap wedge and putter continue to be the top clubs for saving strokes. At a 10 handicap, the 5-iron still costs golfers the most strokes–0.205 strokes per swing. Here, players are generally more consistent, but even slight misses with a long iron can lead to negative results. The “best” category expands to include the driver, which joins the putter, reflecting improved ball speed, strike quality, and dispersion off the tee. Even for 5-handicap golfers, the 5-iron remains the weakest performer, costing –0.136 strokes per swing. The gap in Strokes Gained compared to scratch players is smaller at this level, indicating that skilled players are using their 5-iron more effectively; however, it still does not gain strokes. At this level, the putter remains the most efficient club, and the 3-wood becomes another strong performer. Even scratch golfers face challenges with the 5-iron. It still averages –0.062 strokes per swing compared to the scratch baseline, showing that even the best lose ground with this club. While the difference is minor, it confirms that the 5-iron is unforgiving, regardless of skill level. Interestingly, for scratch players, both the driver and 3-wood produce positive Strokes Gained, making them the only group where the long game truly becomes a scoring advantage rather than a liability.
