True Shooting Attempts Calculator
Turn field-goal and free-throw attempts into True Shooting Attempts (TSA) and True Shooting %, the scoring-efficiency stat that counts the trip to the line properly.
How it works
TSA = FGA + 0.44 × FTA · TS% = points ÷ (2 × TSA) × 100
True Shooting Attempts blend field-goal attempts with free-throw attempts, weighting each trip to the line by 0.44 — the empirical fraction of free-throw trips that actually end a possession, since and-ones, technicals and three-shot fouls mean two made free throws is not always one possession. Dividing points by twice the TSA yields True Shooting %, the cleanest single measure of scoring efficiency because it rewards threes and free throws that raw field-goal percentage ignores.
Worked example
A player takes 18 field-goal attempts and 6 free-throw attempts, scoring 27 points. TSA = 18 + 0.44 × 6 = 20.64. TS% = 27 ÷ (2 × 20.64) = 65.4%, well above the roughly 56% league average.
Frequently asked questions
Why the 0.44 coefficient on free throws?
Not every pair of free throws corresponds to a used possession — some come from and-one plays, technical fouls or three-shot fouls. Analysts settled on 0.44 as the long-run share of free-throw attempts that end a possession, which makes TSA a fair denominator for efficiency.
What is a good True Shooting percentage?
League average sits around 56–58%. Elite scorers push past 62%, while a TS% below 50% usually signals inefficient shot selection. It is best read alongside volume — high efficiency on few attempts is easier than on a heavy load.
How is TS% different from effective field-goal percentage?
eFG% adjusts field-goal percentage for the extra value of threes but ignores free throws entirely. TS% folds free throws in through the TSA denominator, so a player who draws lots of fouls scores better on TS% than on eFG%.
