## What is goals against average?

The goals against average is calculated by multiplying the number of goals allowed by 60 then dividing by the number of minutes played.

## How to calculate goals against average?

Example Problem:

The following example outlines how to calculate a goals against average.

First, determine the total number of goals allowed in a certain number of minutes. For this example, the goalie allowed 10 goals.

Next, determine the number of minutes played for those 10 goals to happen. In this example, the goal played 240 minutes.

Finally, calculate the goals against average using the formula above:

GAA = GA * 60 / M

GAA = 10* 60 / 240

GAA = 2.5 goals per game allowed
