'''Goals against average''' ('''GAA'''), also known as '''average goals against''' ('''AGA'''), is a [statistic](/source/statistic) used in [field hockey](/source/field_hockey), [ice hockey](/source/ice_hockey), [lacrosse](/source/lacrosse), [soccer](/source/soccer), and [water polo](/source/water_polo) that is the [mean](/source/mean) of [goals](/source/Goal_(sports)) allowed per game by a [goaltender](/source/goaltender) or [goalkeeper](/source/goalkeeper) (depending on sport). GAA is analogous to a [baseball](/source/baseball) [pitcher](/source/pitcher)'s [earned run average](/source/earned_run_average) (ERA). In Japanese, the same translation (防御率) is used for both GAA and ERA, because of this.

For ice hockey, the goals against average statistic is the number of goals a goaltender allows per 60 minutes of playing time. It is calculated by taking the number of goals against, multiplying that by 60 (minutes) and then dividing by the number of minutes played. The modification has been used by the [National Hockey League](/source/National_Hockey_League) (NHL) since 1965, the [International Ice Hockey Federation](/source/International_Ice_Hockey_Federation) (IIHF) since 1990 & [Professional Women's Hockey League](/source/Professional_Women's_Hockey_League) (PWHL) since 2024.<ref>{{cite web |url=http://proicehockey.about.com/od/learnthegame/f/goalie_stats.htm |title=How are Goaltending Statistics Calculated? |first=Jamie |last=Fitzpatrick |access-date=June 11, 2010 |archive-date=October 22, 2016 |archive-url=https://web.archive.org/web/20161022085103/http://proicehockey.about.com/od/learnthegame/f/goalie_stats.htm |url-status=dead}}</ref> When calculating GAA, overtime goals and time on ice are included, whereas empty net and shootout goals are not.<ref>

The top goaltenders in the NHL have a GAA of about 1.85–2.10, however this has not been seen since the [Dead Puck Era](/source/Dead_puck_era).<ref>{{Cite web |title=Death of the .900 save percentage: Why stopping the puck is so tough for today’s NHL goalies |url=https://www.dailyfaceoff.com/news/death-of-the-900-save-percentage-why-stopping-the-puck-is-so-tough-for-todays-nhl-goalies |access-date=2026-03-05 |website=Daily Faceoff |language=en}}</ref> Although, the measure of a good GAA changes as different playing styles come and go. The top goaltenders in the [National Lacrosse League](/source/National_Lacrosse_League), however, have a GAA of about 10.00, and the top 2005 [Western Lacrosse Association](/source/Western_Lacrosse_Association) goaltenders had a GAA of about 9.00. At their best, elite [NCAA](/source/National_Collegiate_Athletic_Association) water polo goalies have a GAA between 3.00 and 5.00. 

Since the statistic is highly dependent on the team playing in front of a goalie, [save percentage](/source/save_percentage) is usually considered a more accurate measure of a goaltender's skill, especially in ice hockey and lacrosse, as it takes into account the number of shots the goaltender has faced. For example, in hockey, a goaltender saving 83% of shots, but allowing a 2.00 GAA would be considered worse than a goalie who saves 96% of shots, and has a 4.00 GAA. In soccer, since it is considered a part of the goalkeeper's job to coach defenders on proper positioning to prevent opponents' shots, GAA is more commonly used to evaluate goalkeepers than save percentage.
