Rebound Rate Calculator
Calculate offensive (ORB%), defensive (DRB%), and total rebounding percentage (TRB%) to measure a player's true rebounding impact, normalized for playing time.

Frequently Asked Questions
Rebounding percentage estimates what fraction of available rebounds a player grabbed while on the floor. It normalizes for playing time and team context, making it far more meaningful than raw rebound totals. ORB% measures offensive rebounds; DRB% measures defensive rebounds; TRB% covers both.
NBA ORB% benchmarks: below 3% = below average; 3–7% = average; 7–12% = good; 12–17% = very good; above 17% = elite. Elite offensive rebounders like Dennis Rodman and DeAndre Jordan have posted ORB% above 20% in peak seasons.
NBA TRB% benchmarks: below 10% = below average; 10–15% = average; 15–20% = good; 20–25% = very good; above 25% = elite. Dennis Rodman holds the record for highest single-season TRB%, hovering around 29–30% in his peak seasons.
Raw rebounds per game are influenced by playing time, pace of play, and team shooting percentage (more misses = more rebound opportunities). Rebounding percentage normalizes for all these factors by measuring what fraction of available rebounds the player actually secured while on the floor.
Rebound Rate Formulas
ORB% = 100 × (Player ORB × (Team Minutes / 5)) ÷ (Player Minutes × (Team ORB + Opponent DRB))
DRB% = 100 × (Player DRB × (Team Minutes / 5)) ÷ (Player Minutes × (Team DRB + Opponent ORB))
TRB% = 100 × (Player TRB × (Team Minutes / 5)) ÷ (Player Minutes × (Team TRB + Opponent TRB))
- The (Team Minutes / 5) factor converts team minutes to per-player minutes
- Use season totals (not per-game) for a more stable estimate
