GAA Calculator - Goals Against Average
Enter the number of goals allowed, the minutes played, and the standard game length for your sport. The calculator returns the goaltender's Goals Against Average (GAA) and a performance rating, along with a step-by-step breakdown of the arithmetic. Switch sports to auto-fill the correct game length, or enter a custom value for youth or minor-league schedules.
Formula
Worked example
A goaltender allows 32 goals in 637 minutes of ice time. With a 60-minute game length: GAA = (32 x 60) / 637 = 1920 / 637 = 3.01. The equivalent games played are 637 / 60 = 10.6 full regulation games.
What is Goals Against Average (GAA)?
Goals Against Average (GAA) is the standard statistical measure of how many goals a goaltender allows per regulation-length game. Rather than counting raw goals over a season, GAA normalises the figure against the amount of time the goaltender actually played, making it a fair comparison across goalies who have logged very different minutes. The formula is: GAA = (Goals Against x Regulation Game Length) / Minutes Played. A goaltender who allowed 10 goals in 300 minutes of a 60-minute game gets a GAA of 2.00, exactly the same as one who allowed 20 goals in 600 minutes.
Which goals and minutes count?
Only goals scored while the goaltender is physically in the crease count toward GAA. Empty-net goals, scored when the goaltender has been pulled for an extra attacker, are excluded from all official GAA calculations because the goaltender has no chance to stop them. Shootout goals are also excluded in ice hockey, since a shootout is a skills competition rather than a true game situation. Overtime goals and the overtime minutes played are included. Shutting out a team across a full game counts as zero goals against for that outing. Minutes are recorded to the second in most leagues, then converted to decimal minutes for calculation.
How to use this calculator for multiple sports
Select your sport from the dropdown to auto-fill the standard regulation game length: 60 minutes for ice hockey and lacrosse, 90 minutes for soccer, 70 minutes for field hockey, and 32 minutes for water polo. Enter the total goals allowed and the goaltender's total minutes played, and the GAA appears instantly. For youth or minor-league schedules that differ from the standard, select "Custom game length" and enter the length your league uses. The "GAA per 90 min" output normalises results to a 90-minute basis, which is handy for comparing across sports. Lacrosse and water polo naturally produce higher GAA values than ice hockey because the games are faster-paced and higher-scoring.
GAA vs save percentage: which matters more?
GAA and save percentage (SV%) measure different things. GAA counts how many goals get past the goaltender per game, while SV% measures how many shots the goaltender stops. A goalie backed by a poor defence that allows many shots can have a higher GAA than their skill level deserves, yet still post an excellent SV%. Conversely, a goalie with a stingy defence may record a low GAA even on modest saves. In ice hockey, most analysts consider SV% the more reliable indicator of individual goaltender skill because it adjusts for shot volume. In soccer, where the goalkeeper plays a larger role in organising the backline, GAA remains the dominant metric. Using both together gives the fullest picture.
GAA performance tiers (ice hockey)
| GAA range | Rating | Context |
|---|---|---|
| Below 2.00 | Outstanding | Elite NHL starter territory |
| 2.00 - 2.70 | Good | Solid starter, playoff-calibre |
| 2.70 - 3.00 | Respectable | Competent backup or developing starter |
| Above 3.00 | Below average | Below average for top-flight play |
Standard benchmarks for ice hockey goaltenders. Lacrosse and water polo use higher GAA values by nature of the sport.
Frequently asked questions
What is a good GAA in ice hockey?
In the NHL, a GAA below 2.70 is generally considered good for a starting goaltender. Elite goaltenders in the modern era typically post GAAs in the 1.85 to 2.30 range. GAAs above 3.00 usually indicate either a leaky defence or a goaltender below top-flight standard.
Do empty-net goals count in GAA?
No. Official GAA calculations exclude goals scored into an empty net when the goaltender has been pulled, and also exclude shootout goals in ice hockey. Only goals scored while the goaltender is on the ice in the crease during regulation and overtime are counted.
How is GAA different for soccer compared to hockey?
The formula is the same but the game length changes: hockey uses 60 minutes as the standard, while soccer uses 90 minutes. A soccer goalkeeper allowing 25 goals in 450 minutes has a GAA of (25 x 90) / 450 = 5.00. Because soccer goalkeepers face fewer shots than hockey goalies, GAA values tend to be lower, typically between 0.80 and 1.50 for top-flight teams.
Can I use this calculator for a youth hockey league with 30-minute games?
Yes. Select "Custom game length" from the sport dropdown and enter 30 in the game-length field. The calculator will use 30 minutes as the regulation length so your GAA is comparable across all goalies in that specific league rather than being inflated relative to the 60-minute NHL standard.
Why does lacrosse have such a high GAA?
Lacrosse is a faster, higher-scoring sport than ice hockey. Professional lacrosse goalies routinely post GAAs of 8 to 12 or higher, which does not mean they are poor goaltenders. GAA benchmarks are always sport-specific, so only compare a lacrosse goalie's GAA to other lacrosse goalies, not to hockey or soccer standards.
What is a GAA record in the NHL?
The all-time NHL career GAA record belongs to Alec Connell, who posted a 1.916 GAA across his career in the 1920s and 1930s, an era without helmets and with different rules. Among modern-era goaltenders, the career bests are typically in the 1.80s to 2.20s range. Season records from the current era include values below 1.70, set under especially favourable defensive conditions.
