Calculate rebound rate to measure a player's ability to secure missed shots on both ends of the floor.
Basketball Rebound Rate Calculator (TRB%)
Calculate the gold standard rebounding metric: the percentage of available rebounds a player grabs while on the court.

Understanding the Inputs
Why we need team and opponent stats for accuracy
Minutes Played (MP)
Crucial for the "Rate" calculation. A player who grabs 10 rebounds in 20 minutes is far more dominant than one who grabs 10 rebounds in 48 minutes.
Total Team & Opponent Rebounds
Used to determine "Total Opportunities." If there were only 20 missed shots in a game, grabbing 10 rebounds is historic (50%). If there were 100 misses, 10 rebounds is just okay (10%).
Team Minutes
Standardizes the calculation for 5 players on the court. Usually 48 mins (NBA) or 40 mins (College/FIBA).
This advanced formula calculates the percentage of available rebounds a player obtained while they were on the floor. It adjusts for game length and pace, making it superior to raw "Rebounds Per Game."
Total Rebound Percentage (TRB%) is an advanced basketball statistic that estimates the percentage of available rebounds a player grabs while they are on the court.
An "available rebound" is simply a missed shot. If a player is on the court for 10 missed shots and grabs 2 of them, their Rebound Rate is roughly 20%.
The formula looks complex because it has to adjust for the fact that a player is one of 10 people on the court, and also normalize for the exact minutes played.
TRB% vs. Rebounds Per Game (RPG)
Most fans look at Rebounds Per Game (RPG). While useful, RPG is flawed:
The Pace Problem
In the 1960s, the pace of play was incredibly fast. Wilt Chamberlain averaged 22.9 rebounds per game career. Today, pace is slower. Does that mean Wilt was 2x better than modern centers? Or just that there were 2x more missed shots to grab?
TRB% solves this. It measures share of rebounds, not just total count. This allows us to compare players across eras and different team styles.
The Minutes Problem
A starter playing 40 minutes who grabs 10 rebounds has a TRB% much lower than a bench specialist who grabs 8 rebounds in just 15 minutes. The bench player is actually the more efficient rebounder, and TRB% highlights this dominance.
The Dennis Rodman Standard: Benchmarks
There is Dennis Rodman, and then there is everyone else. Rodman regularly posted TRB% seasons over 25%, peaking at nearly 29.7%—meaning he grabbed almost 1/3 of every missed shot while he was on the floor. That is a statistical outlier of massive proportions.

Offensive vs. Defensive Rebound Rate
While TRB% combines them, they are very different skills:
Defensive Rebound Rate (DRB%): Usually much higher (70-80% of misses are grabbed by defense). A good DRB% is 20%+. It's about securing possession.
Offensive Rebound Rate (ORB%): Historically lower (20-30% of misses are grabbed by offense). A good ORB% is 10%+. It's about creating extra possessions.
How to Improve Your Rebound Rate
Rebounding is often cited as 80% desire and 20% technique, but technique matters:
The Box Out: Making contact with your opponent before looking for the ball is step one. Displacement leads to possession.
Swim Moves: Use arm bars and swim moves (like in football) to get around defenders who are boxing you out.
Anticipation: "The Rodman Science." Majority of long shots (3-pointers) result in long rebounds. Knowing where the ball will bounce based on the shot angle is a learnable skill.
Keep Hands High: Rebounds are often tipped. Keeping hands above shoulder level increases the "win zone" for 50/50 balls.
Frequently Asked Questions
Q&A regarding rebound analytics
Is high Defensive Rebound Rate always good?
Usually, yes. However, some players "steal" rebounds from teammates (uncontested boards) to pad stats. Analytics sometimes differentiate between "Contested Rebound Rate" and "Uncontested."
Does height determine Rebound Rate?
Correlation, not causation. While taller players have higher rates, smaller players like Charles Barkley (6'6") or Russell Westbrook (6'3") have posted elite rates through positioning and athleticism.
What is a good rate for a Point Guard?
For a traditional PG, anything over 5% is great. Players like Russell Westbrook or Luka Doncic often exceed 10-15%, which is akin to centers, giving their team a huge structural advantage.

Who Should Use This?
Contract NegotiatorsUse TRB% to argue a player's value despite low minutes per game.
Fantasy ManagersIdentify "per-minute monsters" who will explode if a starter gets injured.
CoachesIdentify which lineups actually secure the ball best.
Summary
The Basketball Rebound Rate Calculator (TRB%) measures the percentage of available rebounds a player captures.
It is the most accurate metric for evaluating rebounding talent, stripping away pace and playing time to reveal true efficiency on the boards.
