How It Works
Simplified Player Efficiency Rating
PER is a per-minute rating of a basketball player's statistical production. This simplified version captures the core concept.
Simplified Formula
PER = Points + 1.2 x Rebounds + 1.5 x Assists + 2 x Steals + 2 x Blocks - Turnovers - 0.5 x Missed FG
The official PER (created by John Hollinger) uses pace-adjusted per-minute stats with more complex weighting. Average PER in the NBA is set to 15.0 by definition. An MVP-caliber player typically rates 27+.
Worked Example
A player averaging 20 pts, 8 reb, 5 ast, 1.5 stl, 1.0 blk, 3 TO, 8 missed FG.
points = 20rebounds = 8assists = 5steals = 1.5blocks = 1turnovers = 3missed_fg = 8
- 01Positive = 20 + 1.2(8) + 1.5(5) + 2(1.5) + 2(1) = 20 + 9.6 + 7.5 + 3 + 2 = 42.1
- 02Negative = 3 + 0.5(8) = 3 + 4 = 7
- 03PER = 42.1 - 7 = 35.1
