Lineup Impact Calculator
Measure a lineup's net rating — points outscored per 100 possessions while they are on the floor, the standard way to judge a five-man unit.
net rating = (points for − points against) / possessions × 100
Frequently asked questions
Why per 100 possessions?
Because teams play at different paces. Standardising to 100 possessions lets you compare a fast and a slow lineup fairly, by removing the effect of tempo.
What is a good net rating?
Positive means outscoring opponents. Elite lineups post double-digit net ratings, but small samples are noisy, so a few minutes together can mislead.
What are offensive and defensive ratings?
The two halves of net rating: points scored per 100 (offence) and points allowed per 100 (defence). A great lineup is strong at both.
Is this a real metric?
Yes. Net rating is a core team and lineup metric used throughout modern basketball analysis.
