What is the Player Efficiency Rating & How does it work?
Player Efficiency Rating (PER) is a per‑minute rating that attempts to boil down a basketball player’s statistical contributions into a single number. It balances positive actions—points, rebounds, assists, steals, blocks—with negative ones such as missed shots and turnovers, then normalizes the result by minutes played. The core of the calculation is a weighted sum of box‑score stats. Positive contributions are added, while missed field goals, missed free throws, and turnovers are subtracted. The raw value is then divided by the minutes the player was on the court to produce a rate, and finally multiplied by a scaling factor that aligns league‑wide averages.
\frac{ (PTS + REB + AST + STL + BLK) – (FGA – FGM) – (FTA – FTM) – TO }{ MIN } \times factor
PTS = points scored, REB = total rebounds, AST = assists, STL = steals, BLK = blocks, FGM = field goals made, FGA = field goals attempted, FTM = free throws made, FTA = free throws attempted, TO = turnovers, MIN = minutes played, factor = league‑wide scaling constant.
Because PER is expressed per minute, it allows fair comparison between starters and bench players. A higher PER indicates a more efficient and productive performance, making it a valuable tool for analysts, coaches, and fans alike.

Frequently Asked Questions
What is Player Efficiency Rating (PER)?
Player Efficiency Rating (PER) is a per-minute rating that measures a basketball player’s statistical contributions by balancing positive actions like points, rebounds, and assists with negative ones such as missed shots and turnovers.
How do I calculate PER?
To calculate PER, input the player’s box-score stats including points, rebounds, assists, steals, blocks, missed field goals, missed free throws, and turnovers into the calculator. The tool will then compute the PER based on these inputs.
Why is PER important in basketball?
PER helps evaluate a player’s overall performance by normalizing their contributions across different playing times, providing a single metric to compare players’ efficiency.
Can I use this calculator for any sport?
This calculator is specifically designed for basketball and uses statistics relevant to the sport. It may not be suitable for other sports.
How does PER handle missed shots and turnovers?
PER subtracts missed field goals, missed free throws, and turnovers from the positive contributions like points, rebounds, and assists to balance the player’s statistical impact.
What is the significance of minutes played in PER calculation?
Minutes played are used to normalize the player’s stats, ensuring that players with fewer minutes are not unfairly penalized compared to those who play more.
Where can I find my team’s box-score stats for PER calculation?
You can typically find your team’s box-score stats on official sports websites, in game summaries from news outlets, or through your team’s statistics page.
