What is GAA in hockey?

Goals-against average estimates how many goals a goalie allows per 60 minutes played. Lower is better—but the number makes more sense when you know how it is calculated and what it does not tell you.

GAA stands for goals-against average. It expresses the number of goals a goaltender allows for every 60 minutes of playing time.

How is GAA calculated?

The NHL formula multiplies goals allowed by 60 and divides the result by the goalie’s minutes played.

GAA = (GOALS AGAINST × 60) ÷ MINUTES PLAYED

Because the calculation uses minutes instead of simply counting games, it can handle situations where a goalie plays only part of a game.

A simple GAA example

Imagine a goalie allows 20 goals over 600 minutes. Multiply 20 by 60 to get 1,200, then divide by 600. The goalie’s GAA is 2.00.

If another goalie allows 25 goals over the same 600 minutes, the calculation is 1,500 divided by 600, which produces a 2.50 GAA.

Which number is better? For GAA, lower is better. A 2.00 GAA means the goalie has allowed fewer goals per 60 minutes than a goalie at 2.50, assuming the same amount of playing time.

Why GAA is not the same as save percentage

GAA measures goals allowed relative to minutes played. Save percentage measures the share of shots on goal that the goaltender stops. They describe different parts of goalie performance.

A goalie behind a team that allows very few dangerous chances may post a strong GAA while facing a lighter workload. Another goalie may face far more shots and still have a strong save percentage even if the goals-against average is higher.

Why games played and minutes matter

A very low GAA over a tiny sample can be misleading. That is why fantasy competitions and statistical leaderboards often use qualification rules before treating a goalie as an eligible leader.

RosterHouse’s goalie competition uses qualification logic so the GAA race is not decided simply by someone with an unusually small sample of playing time.

What else should you look at?

GAA becomes more useful when read beside other goalie statistics:

  • Games played: indicates the size of the sample.
  • Minutes played: the actual denominator used in the GAA calculation.
  • Save percentage: saves divided by shots faced.
  • Wins: the number of games credited as victories to the goaltender.
  • Shutouts: games in which the opposing team is held scoreless and the goalie qualifies for the individual shutout.

How GAA works in the RosterHouse goalie competition

The idea is intentionally easy to follow: choose a goalie and track the qualified GAA race through the season. Because lower GAA is better, the competition feels different from a scoring pool, where participants are normally chasing the largest total.

This also makes the live NHL goalie statistics page a useful companion to the fantasy competition. You can see the current numbers and still keep the contest rules separate from the underlying NHL statistics.

The shortest definition

If you only want one sentence to remember: GAA is the average number of goals a goalie allows per 60 minutes played.
