True Shooting Percentage (TS%) is a shooting efficiency metric that accounts for all three ways a basketball player can score: two-point field goals, three-point field goals, and free throws. Introduced by researcher Dean Oliver in his landmark 2004 book 'Basketball on Paper,' TS% solved a glaring flaw in traditional field goal percentage — the older metric treated every made shot equally, making a player who hits nothing but corner threes look worse than a player who exclusively scores on close-range two-pointers, even though the three-point shooter generates 50% more points per attempt. The elegance of TS% lies in its simplicity: it expresses how many points a player generates per shooting opportunity, where a shooting opportunity is defined as a field goal attempt plus 0.44 times free throw attempts (the 0.44 factor accounts for the fact that many free throw trips come in pairs or after made baskets). The result is scaled to resemble a percentage — a TS% of 60% means a player generates 60 points per 100 true shooting attempts. In the modern three-point era, TS% has become perhaps the most important single-number shooting metric. Stephen Curry's 2015-16 season TS% of .670 shattered previous records and demonstrated how elite three-point shooting combined with high-percentage mid-range and free throw shooting creates an almost unfair scoring efficiency. The 2023-24 NBA league average TS% hovered around .582. Elite shooters consistently exceed .600, while the threshold for historically great seasons typically sits above .640. GM offices, coaching staffs, and player development departments use TS% to identify which players are genuinely helping or hurting their team's offense. A player averaging 25 points per game with a .520 TS% is actually a significant offensive burden — his team would likely score more with better ball distribution. Conversely, a player averaging just 14 points with a .640 TS% is one of the most efficient scorers on the floor. Contract valuations, lineup decisions, and shot-creation priorities all flow from this single metric in modern front offices.
TS% = PTS / (2 × (FGA + 0.44 × FTA)) Where: PTS = total points scored; FGA = field goal attempts; FTA = free throw attempts; 0.44 = the free throw adjustment factor (accounts for and-one free throws, technical free throws, and situations where only one or two free throws are awarded rather than a full two-shot trip). Worked example — Kevin Durant, 2013-14 MVP season: PTS = 2593, FGA = 1688, FTA = 805. TS% = 2593 / (2 × (1688 + 0.44 × 805)) = 2593 / (2 × (1688 + 354.2)) = 2593 / (2 × 2042.2) = 2593 / 4084.4 = 0.635 (63.5%). This placed Durant among the most efficient high-volume scorers in NBA history that season.
- 1Collect the player's seasonal or game-level statistics: total points scored, total field goal attempts, and total free throw attempts.
- 2Multiply free throw attempts by 0.44 to convert them into 'true shooting possessions' — this adjustment prevents double-counting and-one trips and accounts for technical free throws that generate a point without using a possession.
- 3Add that adjusted free throw figure to total field goal attempts to arrive at the total 'true shooting attempts' denominator.
- 4Multiply the denominator by 2 to place the metric on a percentage scale analogous to field goal percentage (since FG% is made/attempted, and TS% should feel comparable).
- 5Divide total points by the scaled denominator — the resulting decimal multiplied by 100 gives the True Shooting Percentage.
- 6Compare the result against league average (typically .570-.585 in the modern NBA) and position benchmarks to assess efficiency relative to peers.
Curry's .670 TS% in 2015-16 is one of the highest ever recorded for a primary scorer, driven by an absurd three-point percentage of .454 on a then-record 402 attempts and elite free throw shooting at .908.
LeBron's ability to score efficiently from every zone — mid-range, driving, and free throw line — produced a TS% in elite territory, confirming that his 26.8 PPG was genuinely efficient rather than volume-driven.
A TS% right at the league average reflects adequate efficiency — this player is neither hurting nor significantly boosting their team's points-per-possession on possessions they use.
A TS% below 52% on high volume is a net negative for a team's offense — this player is essentially converting fewer than one point per true shooting attempt, creating negative value versus league average ball movement.

Players who draw fouls at elite rates (James Harden, peak Shaq) can post TS%
Players who draw fouls at elite rates (James Harden, peak Shaq) can post TS% above .620 even with mediocre field goal percentages because they generate so many free throw points at high conversion rates.. In the True Shooting Percentage, this scenario requires additional caution when interpreting true shooting percentage results. The standard formula may not fully account for all factors present in this edge case, and supplementary analysis or expert consultation may be warranted. Professional best practice involves documenting assumptions, running sensitivity analyses, and cross-referencing results with alternative methods when true shooting percentage calculations fall into non-standard territory.

Centers who primarily score on dunks, putbacks, and short rolls (like Clint Capela or DeAndre Jordan) can post TS% above .650 — but these numbers are easier to achieve at lower volumes and against less focused defensive attention than primary scorers face.. In the True Shooting Percentage, this scenario requires additional caution when interpreting true shooting percentage results. The standard formula may not fully account for all factors present in this edge case, and supplementary analysis or expert consultation may be warranted. Professional best practice involves documenting assumptions, running sensitivity analyses, and cross-referencing results with alternative methods when true shooting percentage calculations fall into non-standard territory.
Extremely large or small input values in the True Shooting Percentage may push
Extremely large or small input values in the True Shooting Percentage may push true shooting percentage calculations beyond typical operating ranges. While mathematically valid, results from extreme inputs may not reflect realistic true shooting percentage scenarios and should be interpreted cautiously. In professional true shooting percentage settings, extreme values often indicate measurement errors, unusual conditions, or edge cases meriting additional analysis. Use sensitivity analysis to understand how results change across plausible input ranges rather than relying on single extreme-case calculations.

What is a good true shooting percentage in the NBA?
The NBA league average TS% is approximately .580. A TS% above .600 is considered good, above .620 is elite, and above .640 marks one of the most efficient scoring seasons in league history. Below .520 for a high-volume scorer indicates a significant offensive efficiency problem. This is particularly important in the context of true shooting percentage calculations, where accuracy directly impacts decision-making. Professionals across multiple industries rely on precise true shooting percentage computations to validate assumptions, optimize processes, and ensure compliance with applicable standards. Understanding the underlying methodology helps users interpret results correctly and identify when additional analysis may be warranted.
What is the difference between TS% and effective field goal percentage?
Effective field goal percentage (eFG%) adjusts raw field goal percentage to give three-pointers 1.5 times the weight of two-pointers, but it excludes free throws entirely. True Shooting Percentage incorporates free throw efficiency, making it more comprehensive for evaluating overall scoring value. This is particularly important in the context of true shooting percentage calculations, where accuracy directly impacts decision-making. Professionals across multiple industries rely on precise true shooting percentage computations to validate assumptions, optimize processes, and ensure compliance with applicable standards. Understanding the underlying methodology helps users interpret results correctly and identify when additional analysis may be warranted.
Why is the free throw multiplier 0.44 and not 0.5?
Not every free throw trip generates two shots — and-one opportunities produce only one free throw, while technical fouls produce one uncontested attempt. The 0.44 factor is an empirically derived average that accurately converts free throw attempts into possession-equivalents across the full distribution of shooting situations. This is particularly important in the context of true shooting percentage calculations, where accuracy directly impacts decision-making. Professionals across multiple industries rely on precise true shooting percentage computations to validate assumptions, optimize processes, and ensure compliance with applicable standards. Understanding the underlying methodology helps users interpret results correctly and identify when additional analysis may be warranted.
Who has the highest career true shooting percentage?
DeAndre Jordan and other dunker/lob specialists often lead raw TS%, but among high-volume primary scorers, Stephen Curry leads active players. Historically, players like Shaquille O'Neal at his peak (.640s) and Artis Gilmore posted elite marks. This is particularly important in the context of true shooting percentage calculations, where accuracy directly impacts decision-making. Professionals across multiple industries rely on precise true shooting percentage computations to validate assumptions, optimize processes, and ensure compliance with applicable standards. Understanding the underlying methodology helps users interpret results correctly and identify when additional analysis may be warranted.
Can true shooting percentage be over 100%?
No — TS% is bounded by the scoring mathematics of basketball. The theoretical maximum for a player who hits every three-pointer and every free throw approaches about 150%, but in practice, the highest single-season marks among qualifiers are around 70-72% for players who play limited but extremely efficient minutes. This is particularly important in the context of true shooting percentage calculations, where accuracy directly impacts decision-making. Professionals across multiple industries rely on precise true shooting percentage computations to validate assumptions, optimize processes, and ensure compliance with applicable standards. Understanding the underlying methodology helps users interpret results correctly and identify when additional analysis may be warranted.
Does TS% account for shot difficulty?
TS% is completely shot-selection agnostic — it rewards outcomes, not process. A contested mid-range two and an open corner three count equivalently by difficulty; only the result matters. For shot quality, analysts use additional metrics like expected points added or shot quality scores from tracking data. This is particularly important in the context of true shooting percentage calculations, where accuracy directly impacts decision-making. Professionals across multiple industries rely on precise true shooting percentage computations to validate assumptions, optimize processes, and ensure compliance with applicable standards. Understanding the underlying methodology helps users interpret results correctly and identify when additional analysis may be warranted.
How does pace affect true shooting percentage?
Pace does not directly affect TS% because it is a rate stat (points per shooting attempt) rather than a counting stat. However, teams that push pace often generate more transition opportunities, which tend to be higher TS% shots, so fast teams may indirectly boost their shooters' TS% through shot selection.
เคล็ดลับโปร
When scouting free agents or evaluating contract extensions, pair TS% with usage rate to get a complete picture. A player with .620 TS% at 28% usage rate (creating their own shots at high volume) is dramatically more valuable than a player posting .635 TS% at 12% usage (catch-and-shoot specialist). The combination tells you whether the efficiency is self-generated or scheme-dependent.
