The Ultimate Scoring Metric

For decades, basketball fans evaluated a player's scoring efficiency solely by looking at their Field Goal Percentage (FG%). However, standard FG% is deeply flawed because it treats a 3-point shot exactly the same as a 2-point layup, and it completely ignores free throws.

Enter True Shooting Percentage (TS%). Developed by advanced basketball statisticians, TS% is the gold standard for measuring a player's true scoring efficiency because it aggregates 2-pointers, 3-pointers, and free throws into one cohesive metric.

The Mathematics of True Shooting

The genius of True Shooting Percentage lies in how it mathematically converts free throws into standard field goal attempts.

Because two free throws generally take the place of one field goal attempt (when fouled in the act of shooting), we use a multiplier. However, we cannot simply divide free throws by 2, because of "And-1" fouls and technical fouls. Analytics experts established the 0.44 multiplier as the perfectly balanced mathematical constant to represent a true shooting possession.

The Formula

To calculate TS%, you take the total points scored and divide it by twice the number of True Shooting Attempts (TSA).

TS% = Points / (2 * (FGA + (0.44 * FTA)))

Where:
Points=
Total points scored by the player
FGA=
Total Field Goals Attempted
FTA=
Total Free Throws Attempted
0.44=
The mathematical constant for possession estimation

Analyzing the Result

  • If a player has a TS% of 60% or higher, they are scoring at an elite, highly efficient level.
  • A TS% of 55% to 58% is considered average to good in the modern NBA.
  • A TS% below 52% indicates that the player is an inefficient volume scorer, wasting valuable offensive possessions.

Frequently Asked Questions

If every free throw came in pairs, the multiplier would be 0.50. However, 'And-1' situations give a free throw on a possession that already counted as a field goal attempt. Furthermore, 3-point shooting fouls result in three free throws. The 0.44 constant accounts for these statistical anomalies perfectly over a large sample size.

Yes. If a player takes one 3-point shot, makes it, and takes no other shots, their TS% for that game would mathematically be 150%. However, over the course of a full season, no player will exceed 100%.

Effective Field Goal Percentage (eFG%) accounts for the added value of 3-pointers but completely ignores free throws. True Shooting Percentage (TS%) includes free throws, making it the most comprehensive measure of scoring efficiency.
