Basketball shooting percentage calculatorCompute a shooting percentage from shots made and shots attempted.Slugging percentage (SLG) calculatorSlugging percentage measures a hitter's power by total bases per at-bat: SLG = (1B + 2·2B + 3·3B + 4·HR) ÷ AB. Unlike batting average, it weights extra-base hits, so a slugger who hits doubles and homers scores far higher than a singles hitter.Effective field goal percentage (eFG%) calculatorEffective field goal percentage adjusts the standard FG% to credit three-pointers with the extra point they are worth: eFG% = (FGM + 0.5·3PM) ÷ FGA × 100. It gives a fairer picture of a shooter's efficiency than raw field goal percentage.Field goal percentage (FG%) calculatorField goal percentage is the share of shots a player makes: FG% = field goals made ÷ field goals attempted × 100. It is the most basic measure of shooting accuracy in basketball, though it treats two- and three-pointers alike.On-Base Percentage Calculator (OBP)Compute a baseball slash line — OBP, AVG, SLG, OPS and OPS+ — from a batting line, with the formulas and MLB benchmarks to grade the result.True shooting percentage (TS%) calculatorTrue shooting percentage measures scoring efficiency across all shot types — field goals, three-pointers and free throws — at once: TS% = points ÷ (2·(FGA + 0.44·FTA)) × 100. The 0.44 factor approximates how many possessions free throws consume.Total bases (TB) calculatorTotal bases counts every base a hitter earns from hits, weighting each by its value: TB = 1B + 2·2B + 3·3B + 4·HR. Add at-bats and it also returns the slugging percentage (TB ÷ AB).Usage rate (USG%) calculatorUsage rate estimates the share of a team's offensive possessions a player uses while on the floor, through shots, free throws and turnovers: USG% = 100·((FGA + 0.44·FTA + TOV)·(Team MP ÷ 5)) ÷ (MP·(Team FGA + 0.44·Team FTA + Team TOV)). Team minutes default to 240 (5 players × 48 minutes).

For instance, with Player rebounds = 10, Player minutes = 32, Team minutes (total) = 240, Team rebounds = 42 and Opponent rebounds = 40 it returns Rebound percentage (TRB%) = 18.29%.

Frequently asked questions

What does the Basketball rebound percentage (TRB%) calculator actually compute?

It takes Player rebounds, Player minutes, Team minutes (total), Team rebounds and Opponent rebounds and derives Rebound percentage (TRB%) from them. The calculation is live as you type, so the result updates on every change.

What information do I need to provide?

5 values: Player rebounds, Player minutes, Team minutes (total), Team rebounds and Opponent rebounds. Nothing else is required — no account, no file upload.

Can you show a worked example?

With Player rebounds = 10, Player minutes = 32, Team minutes (total) = 240, Team rebounds = 42 and Opponent rebounds = 40, the calculator returns Rebound percentage (TRB%) = 18.29%. Those figures come from running this exact tool, so you can reproduce them by entering the same values.

When would I actually use this?

Running a league or a tournament: how many fixtures a format produces, how the table resolves ties, and what a team still needs to qualify.

What is the most common mistake?

Comparing two figures produced under different rules. A percentage over ten attempts and one over two hundred are not the same claim; the order of tie-breaks, the way a rating is adjusted and what even counts as an attempt are each set by the competition, not by the sport. The number means something next to the rulebook it came from and very little without it.

What is the difference between the Basketball rebound percentage (TRB%) calculator and the Basketball shooting percentage calculator?

This one returns Rebound percentage (TRB%); the Basketball shooting percentage calculator returns Shooting percentage. That is the whole difference — open the one whose figure you need.

Is there a tool for the next step?

Slugging percentage (SLG) calculator is the closest one after this: Slugging percentage measures a hitter's power by total bases per at-bat: SLG = (1B + 2·2B + 3·3B + 4·HR) ÷ AB. Unlike batting average, it weights extra-base hits, so a slugger who hits doubles and homers scores far higher than a singles hitter.

What else is worth having open alongside it?

Effective field goal percentage (eFG%) calculator and Field goal percentage (FG%) calculator — they come up in the same task often enough to be worth a second tab.

Where do the figures come from, and how current are they?

Fixture counts and point totals are pure combinatorics and hold for any competition. The tie-break order is set by each governing body's own regulations — check the one you are actually in.
