True shooting percentage estimates how efficiently a player converts scoring opportunities into points. It uses total points and a denominator built from field goal attempts plus a weighted share of free throw attempts. That makes it broader than field goal percentage, because it accounts for the value of threes and free throws together.
Measure scoring efficiency across twos, threes, and free throws.
TS% = PTS ÷ (2 × (FGA + 0.44 × FTA)) × 100
The 0.44 weight approximates how many extra scoring chances a free throw trip represents. Two free throws are one trip, an and-one adds a free throw to a made basket, and technical free throws stand alone, so the factor is a league-level estimate rather than a precise count. TS% is an efficiency measure, not the percentage of shots a player makes.
| Symbol | Meaning |
|---|---|
| PTS | Total points scored from field goals and free throws. |
| FGA | Field goals attempted, including both two-point and three-point attempts. |
| FTA | Free throws attempted. |
| TS% | Points divided by a possession-weighted shooting denominator, shown as a percentage. |
The denominator is 2 × (15 + 0.44 × 6) = 2 × 17.64 = 35.28. TS% is 24 ÷ 35.28 = 0.6803, or 68.0%. The same 24 points on 20 field goal attempts and 6 free throws would be 53.0%, so shot volume matters.
True shooting percentage measures points scored against the shooting possessions used to score them. The formula is points divided by twice the sum of field goal attempts and 0.44 times free throw attempts. The factor of two converts the denominator into a points scale, so the result reads like a percentage of scoring efficiency.
The 0.44 multiplier estimates how many free throw attempts correspond to one shooting possession. Not every trip to the line consumes a possession, because and-one free throws and technical free throws follow a make or occur outside normal play, so counting each free throw as half a possession would overstate the cost.
True shooting percentage is a volume efficiency measure, not a pure accuracy stat. A player who scores efficiently on high usage and one who scores at the same rate on low usage can post identical marks, even though their roles and difficulty differ. Context such as shot creation and defensive attention still matters.
It also inherits the estimate in the 0.44 weight, which is an average rather than an exact accounting for every player. For most comparisons the approximation is sound, but treat small differences as noise and use the stat to compare scoring value across roles rather than to crown the best shooter.

No. It is a scoring efficiency measure that includes free throws and the extra value of threes. A player can post a high TS% without a high field goal percentage.
