How It Works

How Save Percentage Is Calculated

Formula

SV% = (Shots Against - Goals Against) / Shots Against

GAA = Goals Against / Games Played

Benchmarks

  • SV% above .920: Very good
  • SV% above .910: Average
  • SV% below .900: Below average
  • GAA below 2.50: Very good

    • Worked Example

    500 shots against, 45 goals in 20 games.

    shots_against = 500goals_against = 45games_played = 20
    1. 01Saves = 500 - 45 = 455
    2. 02SV% = 455 / 500 = 0.9100
    3. 03GAA = 45 / 20 = 2.25
    4. 04Shots per game = 500 / 20 = 25.0
