What Is Rebound Percentage (REB%)?

Rebound Percentage is the percentage of missed shots a player grabs while on the court. It estimates the share of all available rebounds, both offensive and defensive, that a player pulls down during the minutes they play.

Formula

REB% = 100 ×REB × (Tm MP / 5)MP × (Tm REB + Opp REB)
REB — The player's own total rebounds
MP — Minutes played by the player
Tm MP — The team's total minutes over that same game or season
Tm REB, Opp REB — Total rebounds grabbed by the player's team and by the opponent, combined, while that player was on the floor
REB% = OREB% + DREB%
OREB%
DREB%

Roughly illustrative split, not a fixed ratio. Defensive rebounds are simply far more available per game than offensive ones league-wide, which is part of why DREB% usually outweighs OREB% within a player's total REB%.

Worked Example

A player grabs 9 rebounds in 30 minutes, in a game where their team and the opponent combine for 84 total rebounds over 240 team minutes.
REB% = 100 × (9 × 48) / (30 × 84)
REB% = 100 × 432 / 2520
REB% ≈ 17.1%

REB% FAQ

What is a good Rebound Percentage by position?

It depends on position. Minutes-weighted averages this season: PG 7.3%, SG 7.3%, SF 9.2%, PF 11.3%, C 16.5%. Anything above the average for a player's own position is a reasonable bar for "good."

Why do some undersized players still post a high REB%?

Certain players play outside the restricted area while others stay near the paint and grab more boards, which isn't directly correlated with height. Positioning, timing, and how far a player roams from the basket matter as much as size.

Does REB% separate offensive and defensive rebounding, or combine them?

REB% is the combined of the two, offensive rebound percentage and defensive rebound percentage together into one overall number.
