What Does Plus Minus Mean in Basketball
Plus minus in basketball shows how a team performs when a specific player is on the floor. It tracks the difference between points scored by the player’s team and points scored by the opponent during that player’s minutes.
If a team outscores the opponent while a player is playing that player will have a positive plus minus. If the opponent outscores the team during that time the player will have a negative plus minus.
Plus minus does not measure individual scoring or defense directly. Instead it reflects overall team impact while that player is involved.
How Plus Minus Is Calculated

Points scored by the team while the player is on the court
Minus
Points scored by the opponent while the player is on the court
The result is the player’s plus minus number.
For example if a player is on the court while their team scores 30 points and allows 20 points their plus minus would be plus 10.
If the team scores 18 points and allows 25 points during that time the plus minus would be minus 7.
What a Positive Plus Minus Means
A positive plus minus means the team performed better than the opponent while the player was on the floor.
This can suggest the player contributed positively through scoring defense playmaking or simply being part of effective lineups.
However it does not guarantee the player personally played well in every way. It reflects team success during their minutes.
What a Negative Plus Minus Means
A negative plus minus means the opponent outscored the team while the player was playing.
This does not always mean the player performed poorly. It can be influenced by tough matchups poor team defense or playing against the opponent’s best lineup.
Context is important when interpreting negative plus minus numbers.
Example Plus Minus Table
| Player | Minutes Played | Team Points | Opponent Points | Plus Minus |
|---|---|---|---|---|
| Player A | 28 | 62 | 55 | plus 7 |
| Player B | 22 | 48 | 54 | minus 6 |
| Player C | 35 | 78 | 70 | plus 8 |
