## 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 %
