Goals Against Average (GAA) Calculator

You can use our Goals Against Average (GAA) Calculator to compute how many goals a goaltender has conceded on average per regulation game.

You can calculate GAA in four simple steps:

  1. Enter the total number of goals conceded by a goaltender during a game. Goals scored in a shootout or when the net is empty are not counted.
  2. In minutes, enter the length of a regulation game (e.g. 60 minutes for ice hockey, 90 minutes for soccer).
  3. Enter the total number of minutes played by the goalkeeper during the contest.
  4. Click on the "Calculate GAA" button.

What is Goals Against Average (GAA)?

In hockey, the GGA statistic refers to the average number of goals a goalkeeper concedes per game. GAA is a metric used to assess a goalkeeper's performance. A goalkeeper with a lower rating is a better goalkeeper. GAA is most typically used in ice and field hockey, but it's also seen in soccer.

GAA Ranges
Grade GAA
Bad >3.00
Respectable 2.70 – 3.00
Good 2.00 – 2.70
Outstanding <2.00

GAA Formula & Example

Our calculator's GAA formula is simple and basic. Apply the following formula:

GAA = Game Length in Minutes / Total Minutes Played * Number of Goals Allowed

As an example, consider a hockey goaltender who conceded three goals in a 60-minute game while only being on the field for 48 minutes. In this case, the GAA is as follows:

GAA = 60 / 48 * 3 = 1.25 * 3 = 3.75

In this case, the goalkeeper's GAA for the game would be 3.75. The goalie's GAA would be 3.00 if he had played the full game, as he allowed an average of 3 goals each game.
