Note
Simplified model: these are the standard published statistics computed from the numbers you enter. They ignore park factors, opponent strength, playing conditions and league adjustments, so results are indicative only and not an official rating.

What is Player Efficiency Rating (PER) trying to measure?+
PER is an all-in-one basketball rating designed to summarize a player's per-minute statistical production into a single number, folding in scoring, rebounding, assists, steals, blocks, and turnovers with pace and league adjustments. It's meant to estimate overall per-minute productivity relative to league average.
What does a PER of 15.00 signify?+
By design, the league average PER in a given season is set to exactly 15.00, so any player's PER can be read directly relative to that baseline. A PER above 15 indicates above-average per-minute production, and below 15 indicates below-average.
What's considered an elite PER?+
A PER above 25 is typically considered MVP-caliber, 20-25 represents an All-Star level player, and 15-20 is a solid role player or starter. The all-time highest single-season PERs, posted by historically dominant scorers, have approached or slightly exceeded 30.
What does PER leave out that limits its usefulness?+
PER is a purely offense-weighted, counting-stat-driven formula that doesn't capture defensive positioning, screen-setting, floor spacing, or team chemistry. A player can inflate their PER with high-volume scoring or rebounding stats while providing little defensive value, which the formula doesn't penalize.
Why is PER adjusted for pace and league scoring context?+
Without adjustment, players on fast-paced, high-possession teams would automatically accumulate more counting stats than equally skilled players on slower teams, and different eras have very different scoring environments. The pace and league adjustments try to put every player's numbers on the same relative scale regardless of team style or era.
