Basketball Possessions & Efficiency Calculator

Estimate how many possessions a team used from its box score, then read points per possession, offensive rating, pace and turnover rate from the same counts.

Team points, 0 to 250
Made and missed field goals, 1 to 150
All free throw attempts, 0 to 100
Offensive boards only, 0 to 60
All turnovers, 0 to 60
Minutes played: 48 NBA, 40 FIBA or NCAA

The estimate adds field goal attempts to 0.44 times free throw attempts, subtracts offensive rebounds (a put-back keeps the same possession alive) and adds turnovers. The 0.44 factor reflects that not every free throw attempt ends a possession, because the last of two or three is often made and team rebounds do not always follow; it is the standard box-score estimate, not an official count. Points per possession is points divided by estimated possessions, offensive rating is that figure per 100 possessions, pace rescales possessions to a 48-minute game, and turnover rate is turnovers divided by attempts plus turnovers.
