About this calculator
Volleyball attack percentage, also called hitting percentage or hitting efficiency, measures how effectively a player converts attack attempts into points while accounting for mistakes. The formula is: Attack % = ((Kills − Errors) / Total Attempts) × 100. Kills are successful attacks that result in a point; errors are attacks that either go out of bounds or get blocked for a point against your team. Subtracting errors from kills penalizes reckless swings and rewards clean, efficient attacking. A positive percentage means you are contributing more points than you are giving away. Elite outside hitters in college and professional play typically maintain attack percentages between 25% and 35%, while top middle blockers can exceed 40% due to shorter, more efficient swings.
How to use
Suppose an outside hitter records 45 kills, 12 errors, and 110 total attack attempts in a tournament. Apply the formula: Attack % = ((45 − 12) / 110) × 100 = (33 / 110) × 100 = 30.0%. A 30% attack percentage is a strong result for an outside hitter at the college or club level. If the same player had 20 errors instead, the result would be: ((45 − 20) / 110) × 100 = 22.7%, showing how much errors drag down overall efficiency.
Frequently asked questions
How do you calculate volleyball attack percentage and what does it mean?
Attack percentage is calculated as ((Kills − Errors) / Total Attempts) × 100. It expresses offensive efficiency as a percentage, where a higher number means you win more points than you concede on your attacks. A score of 0% means your kills exactly cancel your errors, while negative values indicate you are hurting your team more than helping. It is a more complete measure of attacking value than kills alone.
What is a good volleyball attack percentage for college and pro players?
For NCAA Division I players, an attack percentage above 0.250 (25%) is considered solid, and above 0.300 (30%) is excellent. At the professional and international level (FIVB, Pro League), elite attackers regularly post percentages of 50–60% in favorable rotations, particularly middle blockers who face fewer digs. Outside hitters at the pro level typically range from 30–45%, reflecting the greater defensive attention they receive.
Why is attack percentage a better statistic than just counting kills in volleyball?
Kills alone do not account for the errors a hitter commits, which directly cost the team points in rally-scoring. A player with 20 kills and 18 errors is far less valuable than one with 20 kills and 3 errors, yet both have the same kill total. Attack percentage captures the net impact of an attacker by subtracting errors from kills before dividing by attempts, giving coaches and analysts a more honest picture of offensive contribution.
