NBA average pace ≈ 100 possessions/48min. College ≈ 70. High school ≈ 60.
Player Efficiency Rating (PER) is an advanced basketball statistic created by ESPN analyst John Hollinger. It measures a player's per-minute performance while adjusting for pace. The league average is always 15.0, making it easy to understand at a glance: above 15 is above average, below 15 is below average. This calculator uses the standard PER formula components to estimate a player's efficiency rating from per-game statistics. All calculations happen in your browser with zero data sent to any server.
A PER of 15.0 is exactly league average. 20+ is All-Star level, 25+ is superstar territory, and 30+ is MVP caliber. For context, only a handful of players in NBA history have posted a single-season PER above 30.
PER is pace-adjusted and per-minute so you can compare players who play different minutes. A bench player with a 22 PER in 15 minutes is more efficient than a starter with an 18 PER in 35 minutes, even though the starter scores more total points.
PER rewards scoring volume and does not fully capture defensive impact (especially off-ball defense). It also tends to overvalue high-usage players. Use PER alongside other metrics like Win Shares, BPM, and Box Plus-Minus for a complete picture.
