True Shooting Percentage Calculator

How it works

TS% = points ÷ (2 × TSA) × 100, TSA = FGA + 0.44 × FTA · points from makes = 2 × FGM + 3PM + FTM · eFG% = (FGM + 0.5 × 3PM) ÷ FGA · points vs league = (TS% − league TS%) × 2 × TSA · points needed = target × 2 × TSA (rounded up)

Raw field-goal percentage treats a three-pointer like a two and ignores free throws, so it undersells modern scorers. True Shooting fixes that by putting all points over the total scoring possessions a player used. The 0.44 coefficient converts free-throw attempts into possession-equivalents, since not every trip to the line ends a possession (and-ones, technical shots); college analysts often use 0.475, which you can choose under More options. Enter total points, or switch to made shots (field goals, threes and free throws made) to also get eFG%, FG%, FT% and, with three-point attempts, 3P% and the three-point attempt rate. The calculator compares the result with the NBA league average (58.1% in 2025-26) or your own league and turns the gap into points: how many more or fewer points the player scored than a league-average shooter would have on the same attempts. Switch to “Points for a target TS%” to see how many points a given number of attempts must produce.

Worked example

25 points on 18 field-goal attempts and 6 free-throw attempts: TSA = 18 + 0.44 × 6 = 20.64, so TS% = 25 ÷ (2 × 20.64) × 100 = 25 ÷ 41.28 × 100 = 60.6% — above the 58.1% NBA average. A league-average shooter would have scored 0.581 × 41.28 = 24.0 points on those attempts, so the player added about 1.0 point. With made shots of 9 field goals (3 of them threes) and 4 free throws, the 25 points give an eFG% of (9 + 1.5) ÷ 18 = 58.3%. To reach 65% on the same attempts he would need ⌈0.65 × 41.28⌉ = 27 points.
