About Player Efficiency Rating Calculator

This is the classic NBA efficiency formula: points plus rebounds, assists, steals and blocks, minus missed shots and turnovers, then divided by games played. Efficiency counts every box score event at the same weight, which flatters high-volume players, so the negative rate is worth reading alongside it.

Formula
