What is a Basketball PER Calculator?
The Basketball PER Calculator is an essential tool for players, coaches, and scouts to measure a player's all-around efficiency and per-minute productivity on the court. Developed by John Hollinger, the Player Efficiency Rating (PER) is a 'catch-all' metric that summarizes a player's total statistical contribution into a single number.
- • Comparing historical NBA performances across different eras.
- • Evaluating college prospects before the professional draft.
- • Scouting rotational players to find high-impact bench contributors.
By normalizing performance per minute and adjusting for team pace, this tool allows for a fair comparison between players regardless of their role or the style of play of their team.

How Basketball PER Works
The PER formula uses a complex system of weighting that awards points for positive outcomes and subtracts points for negative outcomes.
Positive stats like field goals, rebounds, assists, steals, and blocks increase the score, while turnovers, personal fouls, and missed shots decrease it. The final result is adjusted for the team's pace relative to the league average and normalized so that 15.0 represents a league-average player.
According to Basketball-Reference, the Player Efficiency Rating (PER) is a rating of a player's per-minute productivity, developed by John Hollinger.

Key Concepts Explained
Pace Adjustment
Normalization based on how many possessions a team averages per 48 minutes.
League Average (15.0)
The baseline score where exactly half the league performs better and half worse.
Unadjusted PER (uPER)
The raw efficiency score before team-specific pace and league normalization are applied.
Usage Rate
How often a player finishes a possession, correlating with PER efficiency.

Factors That Affect Your Results
Field Goal Percentage
Because the formula penalizes missed shots, shooting efficiency is the single biggest driver of a high PER rating.
Turnover Rate
Every turnover is heavily penalized, making ball security essential for maintaining a high efficiency score.
Rebound Dominance
Defensive Rebound Percentage adjustments mean that dominant big men often see significantly higher PER scores.
According to NBA Statistics, the league-wide pace average was approximately 98.5 possessions per game during the 2023-24 season.

Frequently Asked Questions (FAQ)
Q: How is PER calculated in basketball?
A: PER is calculated by weighting all of a player's positive accomplishments (like points and assists) against negative ones (like turnovers and missed shots). The raw score is then adjusted for the team's pace and normalized to ensure the league average remains 15.00.
Q: What is a good PER in the NBA?
A: In the NBA, a PER of 15.0 is the league average. Scores above 20.0 typically indicate an All-Star caliber player, while scores above 25.0 are reserved for MVP candidates. Historical greats like Michael Jordan often maintain averages above 30.0.
Q: Who invented the PER (Player Efficiency Rating) stat?
A: The Player Efficiency Rating (PER) was invented by John Hollinger, a former ESPN analyst and NBA executive. Hollinger designed the metric to normalize performance per minute and per possession, which was revolutionary for comparing players across different team tempos.
Q: How do you calculate player efficiency rating?
A: To calculate the player efficiency rating, you need a full box score including minutes played, field goals, free throws, rebounds, assists, blocks, steals, and turnovers. This is combined with league-wide averages to determine the final standardized score.
Q: What does PER mean in basketball stats?
A: PER stands for Player Efficiency Rating. It is a 'catch-all' metric that attempts to summarize a player's total contribution to their team into a single number, allowing for comparisons across different positions and playing styles.
Q: Can PER be used for college or high school basketball?
A: Yes, PER can be adapted for college and high school basketball. While the league constants (like league-average pace and shooting percentages) will differ, the underlying formula effectively measures per-minute productivity regardless of the level of competition.
