Performance Index Rating (PIR) is a total performance metric. European Basketball leagues use it.
The metric calculates using addition and subtraction of positive and negative game factors.
Its initial use was to help select MVP awards in the Euroleague. The metric remains even though the selection process is now done by voting.
Some favor the PIR metric for its simplicity. Critics feel that the metric does not adjust for total playtime and also balances all factors instead of weighting them.
PIR = (Points + Rebounds + Assists + Steals + Blocks + Fouls Drawn) – (Missed Field Goals + Missed Free Throws + Turnovers + Shots Rejected + Fouls Committed
A player statistics show that they have: 26 points, 5 rebounds, 10 assists, 1 steal, 1 block, 4 fouls drawn, 9 missed field goals, 7 missed free throws, 7 turnovers, 9 shots rejected, and 1 foul committed.
PIR = (26 + 5 + 10 + 1 + 1 + 4) – (9 + 7 + 7 + 9 + 1)
PIR = 47 – 33
PIR = 14
Therefore, this player has a Performance Index Rating of 14.
