Question: How are Goaltending Statistics Calculated?
Answer: Goals-Against Average
This is the number of goals allowed per 60 minutes played, rounded to two decimal points.
The Formula: multiply the number of goals allowed by 60 and divide by the total number of minutes played.
The Example: If you allowed 4 goals in 180 minutes your GAA is 1.33 (4 times 60 = 240. 240 divided by 180 = 1.33). The result suggests that for every full game you play, you allow 1.33 goals.
Do not count empty net goals or shootout goals.
Save Percentage
This number expresses a goalie's success based on the number of shots he faces.
The Formula: Divide the number saves made by the number of shots on goal. Work it out to 3 decimal places.
The Example: If you faced 45 shots and allowed 5 goals, your save percentage is .888 (40 saves divided by 45 shots = .888). The number suggests that if you were to face 1,000 shots you would stop 888 of them.
