Hitting percentage (also called hitting efficiency or kill efficiency) is the stat coaches lean on most when judging an attacker.
The idea is simple… it rewards kills and punishes errors.
Below, I’ll show you exactly how it’s calculated, what counts as a kill, error and attempt, and how to read the number once you have it.
How To Calculate Hitting Percentage In Volleyball
To calculate hitting percentage in volleyball, subtract a player’s attack errors from their kills, then divide by their total attack attempts.
Hitting Percentage = (Kills − Errors) ÷ Total Attempts
So a player with 12 kills, 4 errors and 30 attempts is hitting (12 − 4) ÷ 30 = .267.
Here’s the process step by step:
- Count the kills.
- Count the attack errors.
- Count the total attack attempts. This includes every kill, every error and every swing the other team kept in play.
- Subtract the errors from the kills, then divide by the total attempts.
- Round the result to three decimal places.
Why Is It Written As .267 And Not 26.7%?
It’s simply convention.
Box scores show hitting percentage as a three-digit decimal with no zero in front. You’ll usually hear .267 said out loud as “two sixty-seven”.
Some coaches will call it 26.7% efficiency instead, and that’s fine too… it’s the exact same number.
Example 1: A Single Match
Let’s say our outside hitter finishes a match with:
- 12 kills.
- 4 errors.
- 30 total attempts.
(12 − 4) ÷ 30 = 8 ÷ 30 = .267
That’s a solid night. She won her team 8 more points with her swings than she gave away.
Example 2: A Full Season
Hitting percentage really shows its value over a longer stretch.
Say the same player finishes the season with:
- 350 kills.
- 120 errors.
- 900 total attempts.
(350 − 120) ÷ 900 = 230 ÷ 900 = .256
The calculator above handles full-season totals, so you can plug your numbers straight in from your stat sheet.
Example 3: A Negative Hitting Percentage
Now for a rough night:
- 3 kills.
- 5 errors.
- 20 total attempts.
(3 − 5) ÷ 20 = −2 ÷ 20 = −.100
Yes, hitting percentage can drop below zero.
It means the player made more errors than kills, so her swings cost the team more points than they won.
What Counts As A Kill, Error And Attempt?
This is where most stat sheets go wrong.
The formula only works if everyone records the same plays the same way. Most U.S. programs follow the NCAA Volleyball Statisticians’ Manual, so here’s what it says in plain English.
A kill is an attack the other team can’t return, and it leads directly to a point. An error is an attack that directly loses the point.
| What happens on the swing | Kill? | Error? | Attempt? |
|---|---|---|---|
| The attack wins the point | Yes | No | Yes |
| The ball is hit out of bounds | No | Yes | Yes |
| The ball is hit into the net and your team can’t play it | No | Yes | Yes |
| The attacker is blocked straight down and the ball isn’t kept in play | No | Yes | Yes |
| The attacker touches the net, crosses the centerline or hits the antenna | No | Yes | Yes |
| The attack is called as an illegal contact (a thrown or lifted ball) | No | Yes | Yes |
| A back-row player attacks illegally from in front of the 10-foot line | No | Yes | Yes |
| The other team digs the ball or keeps it in play | No | No | Yes |
| A free ball is sent over just to keep the rally alive | No | No | No |
Two rules are worth remembering.
First, every kill and every error also counts as an attempt. So kills plus errors can never add up to more than total attempts.
Second, a swing that stays in play is still an attempt, even though it’s not a kill or an error. If the other team digs it, the NCAA calls this a “0 attack”. The same goes for a ball that’s blocked but kept alive.
If you’re ever unsure about a net call, here’s when you can touch the net in volleyball. And if you want to know how a block touch affects your team’s three contacts, see does a block count as a hit.
The Simple +, −, 0 Tally
You don’t need fancy software to track this.
Just mark every swing as it happens:
- A + for a kill.
- A − for an error.
- A 0 for a swing that stays in play.
At the end of the set, count the pluses and the minuses. Every mark on the sheet counts toward total attempts.
Then plug those three numbers into the calculator. I walk through a full example of this method in my complete guide to hitting percentage.
Hitting Percentage Vs Kill Percentage
These two stats sound alike, but they tell you very different things.
Kill Percentage = Kills ÷ Total Attempts
Kill percentage ignores errors completely. Hitting percentage doesn’t.
Here’s how they compare using our single-match example:
| Stat | Formula | Result |
|---|---|---|
| Kill percentage | 12 ÷ 30 | 40% |
| Hitting percentage | (12 − 4) ÷ 30 | .267 |
That difference matters more than it looks.
Picture two hitters who both get 12 kills from 30 swings. One makes 1 error and the other makes 10.
They share an identical 40% kill percentage. But the first is hitting .367 and the second is hitting just .067.
That’s why most coaches rely on hitting percentage, and why the calculator above shows kill % and error % right alongside it.
How To Read Hitting Stats In A Box Score
Open any college box score and you’ll see the attacking columns written in shorthand:
| Abbreviation | What it means |
|---|---|
| K | Kills |
| E | Attack errors |
| TA | Total attacks (attempts) |
| PCT | Hitting percentage |
So a line reading K 12, E 4, TA 30, PCT .267 is exactly our single-match example.
Is Your Hitting Percentage Good?
It depends a lot on position and level of play. But as a general rule of thumb:
- .250 to .300 or higher is considered good.
- .200 to .250 is fairly average.
- Consistently below .100 is cause for concern.
- Middle blockers usually hit higher, so .350 is good for them and anything over .400 is excellent.
Middles post bigger numbers because they’re mostly set off good passes. Outside hitters and opposites have to deal with far more scrappy, out-of-system sets.

Frequently Asked Questions
Can Hitting Percentage Be Negative?
Yes. If a player makes more errors than kills, their hitting percentage drops below zero. For example, 3 kills and 5 errors on 20 attempts works out to −.100.
What Is A Perfect Hitting Percentage?
A perfect hitting percentage is 1.000. That means every attempt was a kill and there were zero errors. You’ll only ever see it over a small number of swings.
Is Hitting Percentage The Same As Hitting Efficiency?
Yes. Hitting percentage, hitting efficiency and kill efficiency are different names for the same stat, and some stat sheets call it attack efficiency. They’re all worked out as (kills − errors) ÷ total attempts.
Does A Blocked Ball Count As An Error?
Only sometimes. Under NCAA rules, the hitter is charged with an error if they’re blocked straight back down and their team can’t keep the ball in play. If the blocked ball gets dug up and the rally continues, it’s just an attempt.
How Many Attempts Do You Need For A Reliable Hitting Percentage?
There’s no official minimum. Over a handful of swings, one kill or one error can move the number a lot. So I’d judge a player across several matches or a full season rather than a single set. That’s why the calculator flags anything under 20 attempts.
How Do You Calculate Team Hitting Percentage?
Use the same formula with team totals. Add up every player’s kills, errors and attempts, then work out (team kills − team errors) ÷ team attempts. Don’t just average each player’s hitting percentage. That gives a hitter with 5 swings the same weight as one with 40.
