Definition – What is Offensive Rebound Percentage?
Offensive Rebound Percentage (ORB%) is a basketball statistic that puts a player’s number of offensive rebounds in proportion to the total number of offensive rebounds available while they were in active play.
It is Offensive rebounds are important to a team’s offensive strategy as they increase the number of chances that the team has to score on a second (or third) scoring attempt in a play.
Formula – How to Calculate Offensive Rebound Percentage
((Player Offensive Rebounds x (Team Minutes Played ÷ 5)) ÷ (Player Minutes Played x (Team Offensive Rebounds + Opponent Defensive Rebounds))) x 100
Example
A player has 3 offensive rebounds and has played 41 minutes. Their team has 7 offensive rebounds and has played 240 minutes. The opposing team has 27 defensive rebounds.
ORB% = ((3 x (240 ÷ 5)) ÷ (41 x (7 + 27))) x 100%
ORB% = ((3 x 48) ÷ (41 x 34)) x 100%
ORB% = (144 ÷ 1394) x 100%
ORB% = 0.1033 x 100%
ORB% = 10.33 %
Therefore, this player has an offensive rebound percentage of 10.33 %
