The Goals Against Average (GAA) Calculator helps you figure out how many goals, on average, a goaltender allows per full game. It is a very popular tool in sports like ice hockey and soccer, where measuring a goalkeeper’s performance is important. By using this calculator, coaches, players, and fans can easily evaluate defensive skills without doing manual math each time. It works by using the total goals allowed, total minutes played, and the standard length of a full game.
This calculator falls under the Sports Statistics category. It is especially useful for quick evaluations during tournaments, team analysis, or even casual game tracking.
formula
The main formula for calculating Goals Against Average (GAA) is:
Goals Against Average = (Total Goals Against × Minutes in a Full Game) ÷ Total Minutes Played
Total Goals Against
Total Goals Against = Sum of all goals allowed by the goaltender
Total Minutes Played
Total Minutes Played = Sum of all minutes played by the goaltender
Minutes in a Full Game
For Ice Hockey: 60
For Soccer: 90

This table shows average GAA values based on goals allowed and minutes played, so you can skip manual calculations.
| Goals Allowed | Minutes Played | GAA |
|---|---|---|
| 2 | 60 | 2.00 |
| 3 | 60 | 3.00 |
| 5 | 120 | 2.50 |
| 8 | 180 | 2.67 |
| 10 | 240 | 2.50 |
| 12 | 300 | 2.40 |
Example
Let’s say a hockey goalie played 180 minutes and allowed 8 goals.
Step 1: Identify the values:
Total Goals Against = 8
Minutes in a Full Game = 60
Total Minutes Played = 180
Step 2: Apply the formula:
GAA = (8 × 60) ÷ 180
GAA = 480 ÷ 180
GAA = 2.67
So, the goalie’s Goals Against Average is 2.67.
Most Common FAQs
A good GAA in professional hockey is usually below 2.50. The lower the number, the better the goaltender’s performance.
Yes, overtime minutes are included in the total minutes played, which can change the final GAA result.
