Box Plus/Minus estimates a player's contribution to the team per 100 possessions relative to an average player. Positive BPM = better than average.
Box Plus/Minus (BPM) estimates a player's contribution to the team per 100 possessions, relative to a league-average player. A BPM of 0.0 is league average. Our estimate splits into Offensive BPM (OBPM) and Defensive BPM (DBPM).
Players like Nikola Jokic consistently post the highest BPM because of their dominant two-way contributions. Elite passers and efficient scorers who also contribute defensively tend to rank highest.
BPM (Box Plus/Minus) estimates how many points per 100 possessions a player contributes above a league-average player. It uses box-score stats to approximate on-court impact.
A BPM above +2.0 is solid starter level. Above +5.0 is All-Star caliber. Above +8.0 is MVP-level. The all-time single-season BPM leaders include Michael Jordan, LeBron James, and Nikola Jokic.
OBPM measures offensive contribution per 100 possessions, while DBPM measures defensive contribution. Together they form total BPM. Some players dominate offensively while others provide more balanced two-way value.
While PER measures per-minute production, BPM estimates a player's net impact on team performance per 100 possessions. BPM better accounts for playing style and team context, though both rely on box-score data.
