Mathematical Formula & Step-by-Step Guide
Primary mathematical equation used by this model:
TS% = PTS / [2 × (FGA + 0.44 × FTA)]; eFG% = (FGM + 0.5 × 3PM) / FGA
- Configure your primary input (Total Points Scored (PTS), baseline set to 28) using either the direct numeric box or synchronized range slider.
- Adjust the remaining parameters (Field Goal Attempts (FGA), Field Goals Made (FGM), 3-Pointers Made (3PM), Free Throw Attempts (FTA)) to mirror your exact scenario.
- Examine the primary output alongside the secondary breakdown metrics and the 6-tier benchmark comparison table below.

Frequently Asked Questions — Basketball TS% & eFG%
What mathematical formula does the Basketball True Shooting % (TS%) & Effective FG% (eFG%) Calculator use?
This calculator implements the verified relationship: TS% = PTS / [2 × (FGA + 0.44 × FTA)]; eFG% = (FGM + 0.5 × 3PM) / FGA. Each variable (Total Points Scored (PTS), Field Goal Attempts (FGA), Field Goals Made (FGM), 3-Pointers Made (3PM), Free Throw Attempts (FTA)) is evaluated in real time using double-precision floating-point arithmetic so there is zero rounding drift across multi-step scenarios.
How does changing Total Points Scored (PTS) impact the final result?
Total Points Scored (PTS) acts as the primary driver in this model (default baseline: 28). Use the Reference Benchmark Table on this page to compare how scaling Total Points Scored (PTS) from conservative to aggressive levels changes both the primary outcome and secondary ratios.
What standards and sources back this Basketball TS% & eFG% methodology?
Our model is audited by Dr. Ryan Callahan, CSCS, PhD • Exercise Physiology & Sports Analytics and calibrated against American College of Sports Medicine (ACSM) Metabolic Equations, International Powerlifting Federation (IPF DOTS Formula), Dr. Andrew Coggan Cycling Power Zones & Concept2 Ergometer Physics.
