How to Determine Kill Efficiency in Volleyball

Kill efficiency, often called hitting percentage, relates to the number of points a volleyball player scores during attacks to the number of attack errors and total attack attempts she makes. In volleyball terminology, "kill" means an attack that scores a point. You can calculate kill efficiency yourself as long as you keep a close eye on the game so you will get accurate numbers for kills, errors and attack attempts.

      Count the number of kills, attack errors and zero attacks the player makes during the game. A kill hit directly results in a point. An attack error occurs if the player hits the ball out of bounds or into the net, if the referee calls a fault or violation on the player, or if the opposing team blocks the ball and it cannot be kept in play. In a zero attack, the opposing team keeps the ball in play.

      Add together the number of kills, attack errors and zero attacks to get the total number of attack attempts. If a player had 15 kills, five errors and 30 zero attacks in a game, for example, 15 plus five plus 30 equals 50 attack attempts.

    • 3

      Subtract the number of attack errors from the number of kills. If the player had 15 kills and five errors, 15 minus five equals 10.

    • 4

      Divide the result by the number of attack attempts to find the kill efficiency. For example, 10 divided by 50 equals a kill efficiency of 0.2.

    • 5

      Multiply the kill efficiency by 100 to express it as a percentage. For example, 0.2 times 100 equals 20 percent.
