What is Batting Park Factor?

Batting Park Factor is a metric that compares total runs scored (runs scored by both teams) for home games and away games.
The metric can be interpreted in different ways, from a team’s style of play at home compared to on the road, as well as evaluating different baseball parks for their offensive or defensive friendliness.
BPF is expressed to 3 digits. A batting park factor over 1 favors the hitter, while a BPF under 1 favors the pitcher. The further the number is from one, the more heavily it favors either the hitter or the pitcher.
Other statistics such as Home Runs or hits be used as a substitute for runs to see how a certain park favors different elements of the game.

How to Calculate BPF

In Baseball, Batting Park Factor (BPF) is calculated as:

A = (Runs Scored at Home + Runs Against at Home) ÷ Home Games

B = (Runs Scored while Away + Runs Against while Away) ÷ Road Games

BPF = A ÷ B

Example

If team has the following statistics:
Home: Games – 158 | Runs Scored – 790 | Runs Against – 780
Away: Games – 139 | Runs Scored – 841 | Runs Against – 891
then:

BPF = ((790 + 780) ÷ 158) ÷ ((841 + 891) ÷ 139)

BPF = (1570 ÷ 158) ÷ (1732 ÷ 139)

BPF = 9.937 ÷ 12.460

BPF = 0.798

Therefore, the team’s Batting Park Factor is 0.798, or 79.8%.
