Player Efficiency Rating (PER)
A per-minute rating of a player's overall statistical contributions. Higher is better.
Full Definition
Player Efficiency Rating (PER) is a single-number measure of per-minute production developed by John Hollinger. It accounts for positive accomplishments (field goals, assists, rebounds, steals, blocks) and subtracts negative ones (missed shots, turnovers, fouls), adjusted per minute and pace. The league average is always 15.0. PER is useful for quickly comparing overall player impact, but it favors high-usage offensive players and undervalues elite defenders.
What's a good Player Efficiency Rating?
Above 25.0 is MVP caliber, 20-25 is All-Star level, 15-20 is average starter, below 12 is below average.
