True Shooting Percentage Calculator

Free true shooting calculator plus eFG% tool. Enter box score stats to compute TS% and effective field goal percentage for players or teams.

Calculate true shooting percentage from points, field goal attempts and free throw attempts, and compute effective field goal percentage on the same page with plain-language definitions for coaches.

True shooting percentage (TS%) measures scoring efficiency in one number by counting twos, threes and free throws together. This page gives you a true shooting calculator, an eFG% calculator, and short definitions, so you can enter the numbers from any box score.

This calculator uses the 0.44 free throw factor from Basketball-Reference's NBA formula. Sports Reference's college glossary uses 0.475, so a college number can differ slightly.

Points (PTS) Field goal attempts (FGA) Free throw attempts (FTA)

Enter stats to calculate true shooting percentage.

What Is True Shooting Percentage?

Formula: TS% = 100 × PTS ÷ (2 × (FGA + 0.44 × FTA)).

The 0.44 multiplier estimates how many possessions end with free throw trips, so attempts at the line count toward efficiency without treating every foul as a full possession. Sports Reference's college formula uses 0.475 in place of 0.44.

Coaches use TS% to compare guards who shoot mostly threes, wings who mix midrange and drives, and posts who live at the line. Field goal percentage alone leaves out free throws.

More context on shooting value lives on effective field goal percentage, basketball statistics guide and stat sheet setup.

Effective Field Goal Percentage Calculator

eFG% counts made threes as one and a half field goals because they are worth 50% more on the scoreboard.

Field goals made (FGM) Field goal attempts (FGA) Three-pointers made (3PM)

Enter shooting lines to calculate eFG%.

Formula: eFG% = 100 × (FGM + 0.5 × 3PM) ÷ FGA.
