TS% & Efficiency Calculator
Enter a player's shooting stats to calculate True Shooting %, Effective FG%, and four additional efficiency metrics. Updates live as you type.
What is True Shooting Percentage (TS%)?
True Shooting Percentage is the most complete single-number measure of scoring efficiency in basketball. Unlike field goal percentage, TS% accounts for the extra value of three-pointers and weights free throw attempts at 44% of a full field goal attempt — the historically calibrated multiplier derived from actual NBA game data. The formula: TS% = Points ÷ (2 × (FGA + 0.44 × FTA)).
TS% Benchmarks
- 65%+: Elite — top echelon of NBA efficiency. Think peak Rudy Gobert finishing at the rim or a volume three-point specialist at a high clip.
- 60–64%: Excellent — All-Star caliber scoring efficiency. Consistent at this level signals a player who rarely wastes possessions.
- 55–59%: Above Average — solid efficiency, better than most NBA rotation players.
- 50–54%: League Average — serviceable but not a weapon. The NBA-wide TS% hovers around 57% in recent seasons.
- 45–49%: Below Average — a scoring approach that costs the team efficiency. Often seen in mid-range-heavy or low-free-throw-rate players.
- Below 45%: Inefficient — the player is hurting their team with volume scoring at poor rates.
Effective Field Goal % (eFG%) vs TS%
eFG% improves on raw FG% by giving three-pointers 1.5× weight — since they produce 50% more points per make than twos. Formula: eFG% = (FGM + 0.5 × 3PM) ÷ FGA. The difference between TS% and eFG% is that TS% also incorporates free throws, making it the more complete metric for players who draw fouls. A paint scorer like Joel Embiid scores heavily via the free throw line — eFG% understates his efficiency, while TS% captures it fully.
Free Throw Rate (FTr) and 3-Point Rate (3PAr)
Free Throw Rate (FTA ÷ FGA) measures how often a player earns free throws relative to their shot volume — a proxy for drawing contact and attacking the paint. Elite draw-foul players like James Harden have historically posted FTr above 0.50. Three-Point Attempt Rate (3PA ÷ FGA) shows the share of a player's shots that are threes. Modern NBA offenses target a 3PAr above 0.40 for perimeter players as part of shot-quality optimization strategies.
