A goaltender's save percentage looks like a simple stat — saves divided by shots against — but reading ".912" correctly takes some context most box scores don't give you. Here's how to judge the number.
What it measures
SV% = Saves ÷ Shots Against
Take 27 saves on 30 shots against, and SV% = 27 ÷ 30 = .900. Notice the format: hockey reports save percentage as a decimal fraction without the leading zero — ".900", not "90.0%" — the same convention baseball uses for batting average.
Rough bands for NHL goaltenders
There's no official cutoff, but these ranges reflect how the stat is commonly read for starting goaltenders over a full NHL season:
- .920 and above — elite
- .915–.920 — solid, reliable starter
- .905–.915 — roughly league average
- Below .900 — below average
League-average save percentage isn't fixed — it shifts slightly year to year with rule changes, equipment, and the overall shooting talent in the league, so treat these as general bands rather than a permanent line.
What it can't see: shot quality
The basic save percentage formula treats every shot on goal identically — a routine wrist shot from the point counts exactly the same as a clean breakaway or an odd-man rush. A goaltender who faces an unusually difficult mix of shots (more odds-man rushes, more shots from high-danger areas because of a weak defense in front of him) will look worse on raw SV% than one facing the same shot volume from easier locations, even if their actual goaltending is identical.
Advanced stats like expected goals (xG) and goals saved above expected try to correct for this by weighting shots by their location and situation — but they require shot-location tracking data this site's calculator doesn't use, since every provider's xG model is proprietary and non-identical (the same reason we don't publish an xG calculator at all).
Shootouts don't count
Per the NHL's own statistical rules, shootout saves and goals are tracked completely separately from a goaltender's save percentage — the shootout is treated as its own scoring format, not part of regulation or overtime play. If you're calculating SV% by hand from a box score, leave shootout attempts out of both the numerator and denominator.
Comparing goaltenders fairly
Because shot difficulty varies by team and situation, save percentage is most meaningful when comparing goaltenders who face a similar volume and mix of shots (e.g. two starters on similarly-ranked defensive teams) rather than across very different situations — a backup who only plays against weaker opponents, for instance, may post an inflated SV% that doesn't reflect true talent.
