Hockey Save Percentage Calculator

About the Hockey Save Percentage Calculator

Save percentage (SV%) and goals against average (GAA) are the two most fundamental goaltending statistics in hockey. SV% measures what fraction of shots on goal a goalie stops, while GAA calculates how many goals a goalie allows per 60 minutes of play. Together, they provide a comprehensive picture of goaltending performance that fans, coaches, and general managers use to evaluate their netminders.

Our Hockey Save Percentage Calculator computes both SV% and GAA from your inputs: shots faced, goals allowed, and minutes played. It classifies the goalie's performance against NHL benchmarks and shows where they rank on the historical scale. The calculator also breaks down save totals and shows how even small differences in SV% translate to significant goal differences over a full season.

Whether you're tracking your beer league stats, evaluating NHL goaltenders for fantasy hockey, or studying the evolution of goaltending in the data era, This calculator gives you instant, accurate goalie analytics.

When This Page Helps

SV% is the primary metric for evaluating goaltenders because it controls for the number of shots faced, unlike wins or shutouts. A goalie facing 35 shots per game with a .920 SV% is performing better than one facing 25 shots with a .910 SV%. Combined with GAA, you get a complete picture of both rate-based and volume-based goaltending performance.

How to Use the Inputs

1. Enter total shots on goal faced by the goalie.
2. Enter total goals allowed.
3. Enter total minutes played (for GAA calculation).
4. View save percentage, GAA, total saves, and classification tier.
5. Check the benchmark table to see how the performance compares to NHL standards.
6. Use the season projection to see full-season implications.

Example Calculation

Tips & Best Practices

• An NHL-average SV% is around .905–.910; elite goalies finish above .920.
• GAA is more influenced by team defence than SV%. A great goalie on a poor team will have a high GAA but still a good SV%.
• Each .001 of SV% over a full 60-game season translates to roughly 1.8 fewer goals allowed.
• Quality starts (SV% ≥ .913 in a game) are a useful game-level measure of goalie consistency.
• SV% has gradually increased over time as goalies have gotten larger and equipment has improved. A .900 once indicated strong goaltending.
• Even strength SV% (5v5 SV%) is more indicative of true goalie skill than overall SV%, which includes power play shots.

The Evolution of NHL Goaltending

League-average SV% has risen over time as goalies have gotten larger and equipment has improved. This improvement is driven by the butterfly technique revolution, larger goaltenders, improved equipment, and better coaching. What was once an elite SV% later became closer to average.

SV% vs GAA: Which Matters More?

Most modern analysts consider SV% the more informative metric because it isolates the goalie's performance from team defence. GAA is heavily influenced by shots allowed, which depends on skaters. A .920 SV% goalie on a team allowing 35 shots per game will have a 2.80 GAA, while the same goalie on a team allowing 25 shots would have a 2.00 GAA. The goalie didn't change; the defence did.

Advanced Goalie Metrics

Beyond SV% and GAA, the modern analytics toolkit includes GSAx (Goals Saved Above Expected), GSAA (Goals Saved Above Average), and high-danger SV% (save percentage on shots from the inner slot). These metrics correlate more strongly with future performance than raw SV% and help identify goalies who are truly elite versus those benefiting from strong defensive systems.

Frequently Asked Questions

• What is a good save percentage in the NHL?

  In the NHL, the league average SV% is about .905–.910. A good starter's SV% is .915+, very good is .920+, and elite is .925+. The all-time single-season record in the modern era is around .940. Over a full season, .930+ is extraordinary.

• How is GAA different from save percentage?

  SV% measures the rate at which a goalie stops shots (efficiency). GAA measures the number of goals allowed per 60 minutes (volume). A goalie facing 40 shots/game with a .920 SV% will have a higher GAA (3.20) than one facing 25 shots/game with the same .920 SV% (2.00), even though both are equally efficient. GAA conflates goaltending with team defence.

• What is GSAx (Goals Saved Above Expected)?

  GSAx is the modern advanced goaltending metric. It compares a goalie's actual goals allowed to the expected goals (xG) from the shots faced, based on shot quality. GSAx = xGA − GA. A positive GSAx means the goalie stopped more than expected. It accounts for shot quality, unlike raw SV%. It's considered the best publicly available goalie evaluation metric.

• Does SV% account for shot quality?

  No. Raw SV% treats all shots equally. A breakaway counts the same as a routine wrist shot from the point. This is SV%'s main limitation. Advanced metrics like GSAx and GSAA (Goals Saved Above Average, sometimes quality-adjusted) address this by incorporating expected goals models.

• What is a quality start in hockey?

  A quality start is defined as any game where the goalie's SV% is .913 or higher (the approximate league-average save percentage). This is more useful than wins because it isolates the goalie's performance from team offence. A goalie can make 30 saves on 33 shots (.909, not a quality start) and still win 5–3.

• Who has the highest career SV% in NHL history?

  Among goalies with significant careers in the modern era, Dominik Hasek (.922), Tuukka Rask (.921), and Ben Bishop (.921) rank among the highest. Hasek's dominance came with SV% marks that would remain elite by modern standards. The position has seen steady SV% inflation due to larger goalies and improved technique.
