All-star level · true shooting 63.5%
True shooting percentage is the honest shooting measure. It counts all points against all shooting possessions, treating free throws as 0.44 of a possession, so it weights threes and free throws properly where raw field goal percentage does not. Effective field goal percentage takes the simpler route of giving a three-pointer 1.5 times the weight of a two. Both fix the same problem: raw field-goal percentage systematically undervalues anyone who shoots from distance. Efficiency rating rewards volume as well as quality — a player taking many shots accumulates it faster, and it undervalues defence entirely because steals and blocks are only a fraction of defensive contribution. It is a rough single number, not a verdict.
How the Basketball Efficiency Calculator works
Efficiency rating per game alongside true shooting and effective field goal percentage. Raw field goal percentage systematically undervalues anyone who shoots threes or draws fouls; these two fix that.

Frequently asked questions
What is true shooting percentage?
Points divided by twice the shooting possessions, where free throws count as 0.44 of a possession. It is the only common shooting measure that weights twos, threes and free throws properly.
How is effective field goal percentage different?
It only fixes the three-point problem, giving a made three 1.5 times the weight of a two. It ignores free throws, which true shooting includes.
How is efficiency rating calculated?
Points, rebounds, assists, steals and blocks added, then missed shots, missed free throws and turnovers subtracted. It is deliberately simple and correspondingly crude.
What are the limits of efficiency rating?
It rewards volume as much as quality, and it barely measures defence — steals and blocks are a small fraction of defensive contribution, and good positioning registers as nothing at all.
What is a good true shooting percentage?
Around 58% is roughly league average in the modern NBA, with 62% and above excellent. It has risen substantially as three-point volume has grown.
