Use Cases

Track a goaltender's performance

Use this calculator to quickly compute a goalie's GAA after a game or over a season. Enter the total goals allowed and minutes played to see their average goals allowed per full game.

Example: A goalie allows 2 goals in 45 minutes. GAA = (2/45)*60 = 2.67.

Compare goalies fairly

Since GAA is per 60 minutes, you can compare goalies who have played different amounts of time. This helps coaches and fans evaluate performance on an equal basis.

Example: Goalie A: 10 goals in 300 min (GAA 2.00) vs. Goalie B: 5 goals in 150 min (GAA 2.00).

Frequently Asked Questions

What is goals against average (GAA) in hockey?
Goals against average (GAA) is a statistic that measures how many goals a goaltender allows per 60 minutes of play. It is calculated by dividing the number of goals allowed by the number of minutes played, then multiplying by 60. A lower GAA indicates better performance.
How do I calculate goals against average?
To calculate GAA, divide the total goals allowed by the total minutes played, then multiply the result by 60. For example, if a goalie allows 3 goals in 120 minutes, the GAA is (3 / 120) * 60 = 1.50.
Why is GAA based on 60 minutes?
GAA is standardized to a full game length of 60 minutes in hockey. This allows for fair comparison between goaltenders who may play different amounts of time. By scaling to 60 minutes, you can compare performance regardless of ice time.

Tips & Common Mistakes

Tips

  • Ensure you enter the exact minutes played, including overtime, to get an accurate GAA.
  • For season stats, sum all goals allowed and all minutes played across games before calculating.
  • Remember that an empty-net goal is not charged to the goaltender, so exclude those from goals allowed.
  • Use GAA alongside save percentage for a more complete picture of a goalie's performance.

Common Mistakes to Avoid

  • Forgetting to multiply by 60 after dividing goals by minutes, which gives goals per minute instead of per game.
  • Including empty-net goals or shootout goals in the goals allowed total.
  • Using periods played instead of minutes played (e.g., 3 periods instead of 60 minutes).
