Enter the bat speed and pitch seed into the calculator to determine the exit velocity of the baseball.

Bat Speed to Exit Velocity Formula

The following equation is used to calculate the Bat Speed to Exit Velocity.

Ve = MF * (PS) + (1+MF)*BS
  • Where Ve is the exit velocity (mph)
  • MF is the material factor (= .2 for wooded bats)
  • PS is the pitch speed (mph)
  • BS is the bat speed (mph)

The exit velocity of a baseball depends on three factors:

  1. The speed of the pitch
  2. The speed of the bat
  3. The material the bat is made of

The faster the bat and pitch speed, the greater the exit velocity.

How to Calculate Exit Velocity From Bat Speed?

Example Problem:

The following example outlines the steps and information needed to calculate Exit Velocity From Bat Speed.

First, determine the material factor. In this example, the material factor is .2 (wooden bat).

Next, determine the pitch speed. For this problem, the pitch speed is found to be 95 mph.

Next, determine the bat speed. In this case, the bat speed is measured to be 75 mph.

Finally, calculate the exit velocity using the formula above:

Ve = MF * (PS) + (1+MF)*BS

Ve = .2* (95) + (1+.2)*75

Ve = 109 mph
