### 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 intended to be representative of part of a player’s ability. 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.

### How to Calculate Offensive Rebound Percentage

Offensive Rebound Percentage (ORB%) is calculated as:

### 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.

Offensive Rebound Percentage (ORB%) = ((3 * (240/5)) / (41 * (7 + 27))) * 100%

Offensive Rebound Percentage (ORB%) = ((3 * 48) / (41 * 24)) * 100%

Offensive Rebound Percentage (ORB%) = (144 / 984) * 100%

Offensive Rebound Percentage (ORB%) = 0.1463* 100%

Offensive Rebound Percentage (ORB%) = 14.63%

Therefore, this player has an offensive rebound percentage of 14.63%.

Their team has 7 offensive rebounds and has played 240 minutes.
