Hitting percentage is the main stat for judging a volleyball attacker. It tells you how many points a hitter wins per swing, after taking away the points they give up with errors. Use the calculator below for a match or a whole season, then read on for the formula, what counts as a kill or an error, and what a good hitting percentage looks like.

The hitting percentage formula
Hitting percentage = (kills − attack errors) ÷ total attempts
For example, a hitter with 12 kills, 4 errors and 30 attempts hits (12 − 4) ÷ 30 = .267. Volleyball writes it as a three-digit decimal, like a batting average, so .267 means the hitter won a net 26.7 points per 100 swings.
Hitting percentage runs from 1.000 (every swing a kill) to −1.000 (every swing an error). It goes negative whenever a hitter makes more errors than kills.
What counts as a kill, an error and an attempt
These definitions follow the NCAA statistics conventions, as summarized by the American Volleyball Coaches Association (AVCA):
| Stat | What it means | Examples |
|---|---|---|
| Attempt | Any attack meant to score a point | Spikes, tips and roll shots; not a free ball sent over to keep the rally alive |
| Kill | An attack that directly leads to a point | The ball lands in, or the defense can’t keep it in play |
| Attack error | An attack that directly gives the other team a point | Hit out, into the net or the antenna, blocked for a point, or a line or net violation |
| Zero attack | An attack that stays in play | The other team digs it and the rally continues |
Zero attacks count as attempts, but not as kills or errors. That’s why a hitter who keeps the ball in play without scoring has a lower hitting percentage than one who scores more, even with the same number of errors.
What’s a good hitting percentage in volleyball?
It depends on position and level. Middle blockers usually post the highest numbers because they attack fewer, better-set balls; outside hitters take the most swings, often against a set block, so their numbers are lower. An analysis of NCAA Division I men’s stats by Dartmouth Sports Analytics found the best middles hitting above .333, while even the top outside hitters were mostly in the .200s.
| Hitting % | Rough rating |
|---|---|
| Below .000 | More errors than kills |
| .000–.149 | Below average |
| .150–.249 | Average |
| .250–.349 | Good |
| .350 and above | Excellent |
Use these as a rough guide only, and compare players with others in the same position and league. A .250 from an outside hitter who takes 40 swings a match can be worth more than a .400 from a middle who takes 10.
Other attacking stats
- Kill percentage: kills ÷ total attempts. It shows how often a hitter scores, ignoring errors.
- Error percentage: attack errors ÷ total attempts. Useful for spotting hitters who score a lot but also give away points.
- Kills per set: total kills ÷ sets played. It shows how much of the offense a hitter carries.
The calculator shows kill percentage, error percentage and zero attacks as well as hitting percentage.
How to improve your hitting percentage
- Cut errors first. Because errors are subtracted, turning one error into a zero attack raises your hitting percentage as much as adding a kill.
- Use the tip and roll shot. Against a big block, a smart off-speed shot keeps the ball in play or scores instead of getting blocked.
- Hit around the block. Work on hitting line and sharp cross-court so you aren’t swinging straight into hands.
- Work with your setter. Many errors come from poor sets; agree on tempo and location in practice.
- Get more reps. A rebounder or spike trainer lets you groove your arm swing at home; see the best volleyball rebounders and the best volleyball training equipment.
Frequently asked questions
Can hitting percentage be negative?
Yes. If a hitter makes more attack errors than kills, the result is below zero, down to −1.000 if every swing is an error.
Why is hitting percentage written as .300 instead of 30%?
It’s a convention borrowed from baseball batting averages. A .300 hitting percentage means a net 30 points won per 100 swings.
Does a blocked ball count as an attack error?
Yes, if the block wins the point. If the ball is blocked but your team or the other team keeps playing, it’s a zero attack.
Do tips count as attack attempts?
Yes, when they’re attacks meant to score. A ball sent over just to keep the rally going, often called a free ball, doesn’t count.
What’s a good hitting percentage for a team?
Team hitting percentage is calculated the same way using team totals. Many coaches aim for around .250 to .300, but it varies a lot by level.
