Smash Factor Calculator
This smash factor calculator divides your ball speed by your club head speed and tells you how your strike compares with tour players using the same club. It also works backwards: enter a ball speed and a smash factor to estimate your swing speed, or a swing speed to see the ball speed you should be getting. To see what your speed is worth in distance with every club, use the golf swing speed calculator.
What is smash factor?
Smash factor is the ratio of ball speed to club head speed: smash factor = ball speed ÷ club head speed. It shows how efficiently the club's speed is passed to the ball. Two golfers who swing at 100 mph can send the ball off at 140 mph or 149 mph depending on where they strike the face, and that difference is distance neither of them swung any harder for.
Smash factor chart by club
TrackMan's tour averages, 2023 season:
| Club | PGA Tour | LPGA Tour |
|---|---|---|
| Driver | 1.49 | 1.49 |
| 3-wood | 1.47 | 1.47 |
| 5-wood | 1.47 | 1.46 |
| Hybrid | 1.47 | 1.44 |
| 3-iron | 1.46 | – |
| 4-iron | 1.44 | 1.43 |
| 5-iron | 1.41 | 1.42 |
| 6-iron | 1.39 | 1.41 |
| 7-iron | 1.34 | 1.38 |
| 8-iron | 1.33 | 1.36 |
| 9-iron | 1.29 | 1.30 |
| Pitching wedge | 1.24 | 1.25 |
The calculator shows the club and ball speeds behind each figure too. With a driver, PGA Tour players average 115 mph of club speed and 171 mph of ball speed; LPGA Tour players 96 mph and 143 mph.
What's a good smash factor for amateurs?
TrackMan's Combine data gives driver averages by handicap. The gap between a scratch golfer and an average one is small, about 0.05, but at 100 mph of club speed it is worth 5 mph of ball speed.
| Handicap | Men | Women |
|---|---|---|
| Scratch or better | 1.49 | 1.46 |
| 5 | 1.45 | 1.45 |
| 10 | 1.45 | 1.44 |
| Average golfer (men 14.5, women 15) | 1.44 | 1.41 |
| Bogey golfer | 1.43 | – |
TrackMan publishes amateur averages for the driver only. For other clubs, the calculator rates your number against the tour average for the same club: within 0.03 is good, within 0.07 is a typical amateur strike.
Why smash factor drops as loft rises
A lofted club meets the ball with a more glancing blow. More of the energy goes into spin and less into ball speed, so a 1.24 with a pitching wedge is as good a strike as a 1.49 with a driver. That's why a smash factor only means something next to the club it was hit with.
Smash factor, ball speed and distance
Ball speed drives distance more than anything else. Comparing the PGA Tour and LPGA Tour driver averages, each extra mph of ball speed is worth roughly 2 yards of carry. A 100 mph swing at 1.44 instead of 1.49 leaves 5 mph of ball speed, about 10 yards, on the tee without swinging any faster. Launch decides how much of that ball speed turns into carry: see the ideal driver launch angle, and golf ball speed benchmarks for where tour players and long drivers sit.
Frequently asked questions
What is smash factor in golf?
Smash factor is ball speed divided by club head speed. It measures how much of the club's speed goes into the ball, which mostly comes down to how centrally you strike it. A 100 mph swing that sends the ball off at 145 mph has a smash factor of 1.45.
What is a good smash factor for a driver?
PGA Tour and LPGA Tour players both average 1.49 with a driver, according to TrackMan. Around 1.45 is good for an amateur: TrackMan's Combine data puts the average male golfer, a 14.5 handicap, at 1.44 and a scratch golfer at 1.49. About 1.50 is the practical ceiling.
What is a good smash factor for a 7-iron?
The PGA Tour average with a 7-iron is 1.34 and the LPGA Tour average is 1.38. An amateur in the low 1.30s is striking it well. Don't compare it with your driver: more loft always means a lower smash factor.
What is the maximum smash factor in golf?
About 1.50 with a driver. The Rules of Golf limit how springy a clubface can be, so even a perfectly centred strike can't push much past that, and a reading above about 1.52 usually means the launch monitor misread the club speed. Lofted clubs top out lower.
How does smash factor link ball speed and swing speed?
Ball speed is club head speed multiplied by smash factor, so either speed gives the other once you know the smash factor: a 100 mph swing at 1.45 sends the ball off at 145 mph. To turn a ball speed into a swing speed for every club, use the golf swing speed calculator.
How do you improve your smash factor?
Strike the centre of the face: impact tape or foot powder spray shows where you're making contact. With a driver, a slightly upward strike and a shaft and loft that suit your swing help too. Swinging harder doesn't raise smash factor, and often lowers it.

This smash factor calculator from Moor Golf compares your numbers with TrackMan's PGA Tour and LPGA Tour averages from the 2023 season (published May 2024). Launch monitors measure club and ball speed differently, so compare figures from the same device, averaged over several shots.
