How to Use This Calculator
  1. Enter your Club Head Speed in mph.
  2. Set your Attack Angle in degrees (negative for descending blow, positive for ascending with driver).
  3. Optionally enter measured Ball Speed and Spin Rate; leave Ball Speed at 0 to estimate it from clubhead speed.
  4. Review Estimated Carry Distance, Total Distance, Smash Factor, Optimal Launch Angle, and Optimal Spin Rate.
  5. Compare your inputs against the optimal values to identify equipment or swing adjustments.

What each input means

Club Head Speed (mph)
Driver clubhead speed in mph. PGA avg ~113, amateur avg ~93.
Attack Angle (degrees)
Angle of attack: positive = upward hit, negative = downward. PGA avg with driver: -1.3°.
Ball Speed (mph)
Measured ball speed. Leave at 0 to estimate from clubhead speed (1.48 smash).
Spin Rate (rpm)
Backspin rate in rpm. PGA driver avg ~2,686 rpm.

What each result means

Estimated Carry (yards)
Estimated carry distance with current launch conditions.
Estimated Total Distance (yards)
Carry plus roll distance estimate.
Smash Factor
Ball speed / clubhead speed. Ideal driver: 1.48-1.50.
Optimal Launch Angle (degrees)
Recommended launch angle for maximum carry distance.
Optimal Spin Rate (rpm)
Recommended spin rate for maximum carry distance.
Potential Distance Gain (yards)
Additional yards possible with optimal launch conditions.
Ball Speed Used (mph)
Ball speed used in calculations (measured or estimated).

How this is calculated

Worked example, using the default values

  1. Identify Input Parameters
    4 parameters
    Club Head Speed (mph) = 100, Attack Angle (degrees) = 0, Ball Speed (mph) = 0, Spin Rate (rpm) = 2700 = 4 input(s) provided
  2. Calculate Estimated Carry
    Estimated Carry = rawCarry * 0.035
    9.7 = 9.7
  3. Calculate Estimated Total Distance
    Estimated Total Distance = carryDistance * (1 + rollFactor)
    10.9 = 10.9
  4. Calculate Smash Factor
    Smash Factor = estimatedBallSpeed / clubHeadSpeed
    1.48 = 1.48
