True Shooting Percentage Calculator

Calculate true shooting percentage (TS%) — the shooting-efficiency stat that credits three-pointers and free throws properly.

Informational only — not a substitute for official league statistics or professional judgment.

How it's calculated

TS% = Points ÷ (2 × (FGA + 0.44 × FTA)) × 100 Example: 28 points on 18 field goal attempts and 6 free throw attempts TS% = 28 ÷ (2 × (18 + 0.44 × 6)) × 100 ≈ 68.4%

Assumptions

  • Uses the standard 0.44 free-throw-attempt weighting adopted across basketball analytics sites (Basketball Reference, FanGraphs-style glossaries) — a league-wide empirical constant, not an exact per-player figure.

Frequently asked questions

Why is true shooting percentage better than field goal percentage?

Field goal percentage treats every made shot the same, so a player who scores efficiently from three-point range or draws free throws looks worse than their actual scoring efficiency. TS% weighs points actually scored per shooting possession, giving full credit for threes and the lower cost of free-throw trips.

What counts as a good true shooting percentage?

In the modern NBA, a TS% above 58% is considered very good for high-usage scorers, and the league average is typically in the mid-50s. Big men who shoot mostly at the rim often post the highest TS% marks in the league.

Where does the 0.44 factor in the formula come from?

Free-throw trips aren't all equivalent to a single shot attempt — some are from and-one fouls, technicals, or two-/three-shot fouls. The 0.44 multiplier is a league-wide empirical estimate of how many "true" individual scoring attempts each free throw represents, refined over years of use by basketball analytics sites like Basketball Reference.

Can true shooting percentage exceed 100%?

Yes, in theory — a player who scores efficiently on threes and free throws in a small sample can post a TS% above 100%, since it measures points per shooting possession rather than a simple make/attempt ratio. This is rare over a full season but common in single-game calculations.
