Goals Against Average Calculator
Goals against average is the goals a goaltender allows per sixty minutes of play. Enter goals against and minutes played.
Calculate goals against average
Fill in the fields and select Calculate.
What you'll need
To use the goals against average calculator, have these figures ready:
- Goals against — for example, 120.
- Minutes played — for example, 3000.
The calculator then returns the goals against average the moment you press calculate.
How it works
Goals against average = (goals against × 60) ÷ minutes played
You enter the goals against and minutes played, and the calculator returns the goals against average using the formula above.
When to Use
Use the goals against average (GAA) calculator to measure how many goals a goaltender allows per 60 minutes of play. GAA is one of the traditional goaltending metrics used alongside save percentage to evaluate performance. Lower is better — a goaltender who keeps the GAA low is keeping the team in games.
What the result tells you
A goals against average around 2.50 is solid and the best goaltenders sit near 2.00. Like a team defensive stat, it reflects the skaters in front of the goalie as much as the goalie themselves, which is why save percentage is often preferred to judge a netminder on their own.
Benchmarks & Interpretation
Here is how typical results are categorized and interpreted:
| Value / Range | Rating | Description |
|---|---|---|
| Below 2.00 | Elite | Outstanding goaltending. Among the best in the league. |
| 2.00 – 2.50 | Very good | A strong goaltender who limits scoring opportunities. |
| 2.50 – 3.00 | Average | A typical GAA for starting NHL goaltenders. |
| 3.00 – 3.50 | Below average | Allowing too many goals. Defence or goaltending needs improvement. |
| 3.50+ | Poor | A struggling goaltender or one playing behind a weak defence. |
Pro Tips & Advice
GAA is influenced by both goaltender performance and team defence. A goaltender playing behind a strong defensive team will naturally have a lower GAA than one facing a barrage of shots. To improve GAA, work with your defenders on communication, positioning, and clearing rebounds. As a goaltender, focus on high-danger save situations — saves from the slot and in close are the most impactful for lowering GAA. Shutout-level focus in the first and third periods is especially important because early goals deflate the team and late goals seal losses.

Worked example
120 goals against over 3000 minutes is (120 × 60) ÷ 3000, which is 2.40.

GAA or save percentage?
Save percentage isolates the goalie better, since GAA depends on how many shots the defence allows. Read the two together for a fuller picture.
How does GAA differ from save percentage?
GAA measures goals allowed per 60 minutes, while save percentage measures the proportion of shots stopped. A goaltender who faces few shots (strong team defence) can have a good GAA with a mediocre save percentage, and vice versa.
What factors beyond goaltending affect GAA?
Team defence, shot quality allowed, power play goals against, and even the score of the game (teams take more risks when trailing) all affect GAA. This is why save percentage and GSAx are often preferred for isolating goaltender performance.
