Volleyball Hitting Percentage Calculator

Hitting percentage is volleyball's standard offensive efficiency stat, and this calculator uses the same formula coaches and stat crews have used for decades: kills minus errors, divided by total attempts. Subtracting errors is what separates it from a simple kill rate — a hitter who racks up kills but also hits plenty of balls into the net or out of bounds will see this number pulled down for every error, since an error is effectively the opposite of a kill rather than a neutral outcome. Kill percentage, by contrast, only looks at kills over attempts and doesn't penalize errors at all, so it's possible for a volume attacker to show a strong kill percentage while their hitting percentage tells a less flattering story once errors are factored in.

Error percentage isolates just the error side of that same ratio. The efficiency rating buckets translate the raw hitting percentage (which typically ranges from negative values up through the .400s) into a 1-to-5 scale: below .100 is Below Average, .100-.199 Average, .200-.299 Good, .300-.399 Excellent, and .400 or above Elite — thresholds that roughly track how hitting percentage is talked about at the college level, where a .300 hitter is considered a strong offensive threat. Service aces and digs are collected as inputs but don't factor into any of the four calculated outputs here; they're tracked for context on the same stat line since they're commonly reported together, not because this particular tool's math depends on them.
