PERPlayer Efficiency Rating
PER is a per-game number summarizing everything a player does — scoring, rebounds, assists, defense, and turnovers.
Formula
PER = (PTS + REB + AST + STL + BLK − (FGA − FGM) − (FTA − FTM) − TO) / GPExample
A player with totals of 84 PTS, 22 REB, 12 AST, 6 STL, 2 BLK on 60 FGA / 28 FGM, 18 FTA / 14 FTM, 9 TO across 4 games: (84+22+12+6+2 − 32 − 4 − 9) / 4 = 81 / 4 = 20.3.
Why it matters
Box-score stats reward role players unevenly. PER lets you rank a center who blocks shots against a guard who passes — same scale, same context.
In depth
Player Efficiency Rating rewards positive actions (points, rebounds, assists, steals, blocks) and subtracts negative ones (missed shots, turnovers). The result is a single number you can rank players by.
ArcStat’s PER is the simplified per-game variant — the NBA’s "Efficiency (EFF)" formula. The full Hollinger PER also adjusts for league pace and team context, which requires data we don’t yet aggregate. Pace-adjusted PER ships in a future update.
A simplified PER above 25 is exceptional in a barangay or corporate league; 15–20 is solid. Below 10 usually means the player is doing more harm than good.
