The Math / Science

The Performance Index Rating is a basketball statistical formula that is used by the Euroleague Basketball Company's first and second tier competition, the EuroLeague and the EuroCup, as well as various European national domestic and regional leagues. It is used to determine the league's MVP of the Week and regular season MVP awards.

The formula for Basketball Performance Rating is:

$PIR = (PTS+REB+AST+STL+BLK+FD)-((FGA-FGM)+(FGA-FGM)+TO+SR+FC)$

where:

PIR = Performance Index Rating
PTS = number of points
REB = number of rebounds
AST = number of assist
STL = number of steals
BLK = number of bocks
FD = number of fouls drawn
FGA = number of field goals attempted
FGM = number of field goals made
TO = number of turnovers
SR = number of shots rejected
FC = number of fouls committed

Basketball Statistics Calculators

Assists per Game: Enter comma separated values for the number of assists in each game (e.g., 2,4,0,0,4,5,6), and compute the assists per game average, number of games, total assists, fewest assists (min), and most assists (max)
Turnovers per Game: Enter comma separated values for the number of turnovers in each game (e.g., 2,4,0,0,4,5,6), and compute the turnovers per game average, number of games, total turnovers, fewest turnovers (min), and most turnovers (max).
Rebounds per Game: Enter comma separated values for the number of defensive rebounds and offensive rebounds in each game (e.g., 2,4,0,0,4,5,6), and compute the rebounds per game average, number of games, total rebounds, fewest rebounds (min), and most rebounds (max), and then the same stats for defensive and offensive rebounds (total, average, min and max).
Fouls per Game: Enter comma separated values for the number of fouls in each game (e.g., 2,4,0,0,4,5,6), and compute the fouls per game average, number of games, total fouls across all games, fewest fouls (min), and most fouls (max).
Free Throw Percentage: Computes the free-throw percentage based on free throws attempted and made.
Basketball Scoring Efficiency: Computes an efficiency metric based on a collection of stats associated with a player or team across a number of games played.
Basketball Shooting Efficiency (AKA Effective Field Goal Percentage): Computes the metric based on the number of 2 point and 3 point goals made and the number of attempts within a single game.
Two Point Shooting Percentage: Compute the percent shooting and total score made on 2 point shots.
Three Point Shooting Percentage: Compute the percent shooting and total score made on 3s.
Performance Index Rating: Computes a basketball metric is used by the Euroleague Basketball Company's first and second tier competition, the EuroLeague and the EuroCup. The metric is computed as a function of numerous individual game metrics.
