## 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%) calculates as:
$\frac{\text{Player Offensive Rebounds}\times\frac{\text{Team Minutes Played}}{5}}{\text{Player Minutes Played}\times(\text{Team Offensive Rebounds}+\text{Opponent Defensive Rebounds})}\times100\%$

## 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 * 34)) * 100%
Offensive Rebound Percentage (ORB%) = (144 / 1394) * 100%
Offensive Rebound Percentage (ORB%) = 0.1033 * 100%
Offensive Rebound Percentage (ORB%) = 10.33 %
Therefore, this player has an offensive rebound percentage of 10.33 %.

## What counts as a Defensive Rebound in Basketball?

In basketball, a defensive rebound is recorded to the player who passes the ball to a teammate who then scores a basket.
In the NBA, assists that result in points from free throws (the pass is made to a player who is then fouled, followed by that player making a basket through a free throw) are not counted, however, they are counted in FIBA (International Basketball Federation) matches.
