Smash Factor is ball speed divided by club speed
Smash Factor relates to the amount of energy transferred from the club head to the golf ball.
The higher the smash factor the better the energy transfer. A golfer would hope to achieve a smash factor near 1.50 on driver shots.
That means for a 100 mph club speed the ball speed would be 150 mph. The higher the loft of the club, the lower the smash factor is expected to be. A PW should have a smash factor near 1.25.
Golfer A has a club speed of 100 mph and a smash factor of 1.40. Golfer A’s ball speed is 140 mph.
Golfer B has a club speed of 100 mph and a smash factor of 1.50. Golfer B’s ball speed is 150 mph.
The 10 mph difference in ball speed between Golfer A and Golfer B equates to approximately 20 yards in distance between the two golfers even though they have the same club speed.

The standard assumption for smash factor comes from the TrackMan Optimizer. For the driver, a club speed of 94 mph, attack angle of 0 degrees, and optimized carry results in a smash factor of 1.46. For a 6-iron, a club speed of 80 mph and mid-trajectory results in a smash factor of 1.38. For a PW, a club speed of 72 mph and mid-trajectory results in a smash factor of 1.19.
What our TrackMan Masters say about Smash Factor…
Andrew Rice Berkeley Hall Golf Club, United States
“Smash factor is often misunderstood as being representative of only how centered a ball was struck.
I stress that it purely represents how well a player converted club speed into ball speed.
It is also possible to have a smash factor that is too high with certain clubs.”
James Leitz Pinewood Country Club, LA, US
“Smash factor is used to determine the efficiency of impact.
Face to path relationships, spin loft, and impact point location are the main factors to look at after you have determined that the smash factor is too low.”
Richard Woodhouse KDV Sports. Australia
“During an initial assessment of a golfer I will observe smash factor, in particular with the driver.
If a golfer’s attack angle, dynamic loft, face to path numbers, and impact location are good, then I will definitely question if the equipment is the correct fit.
If these items are not optimal, then I will educate the player to understand what we are looking for.
From there we can begin work on the primary improvement which will be the parameter that is furthest from optimal.”
