Smash Factor Calculator
The Math
Smash Factor = Ball Speed / Clubhead Speed
Smash factor is the measure of energy transfer from the clubhead to the golf ball. It is primarily dictated by centering of contact and the club's COR (Coefficient of Restitution).
| Club | PGA Tour Avg | Theoretical Max |
|---|---|---|
| Driver | 1.48 | 1.52* |
| 6 Iron | 1.38 | 1.42 |
| PW | 1.25 | 1.29 |
*USGA rules limit COR, making true >1.52 impossible without faulty radar readings.
