About the True Shooting Percentage Calculator
This true shooting percentage calculator measures how efficiently a basketball player scores, counting two-pointers, three-pointers and free throws together. Enter field goals made and attempted, three-pointers made and attempted, and free throws made and attempted for a game or a season, and it returns true shooting percentage (TS%), effective field goal percentage (eFG%), plain FG%, 3P%, FT%, total points and true shooting attempts.
Plain field goal percentage treats a made three the same as a made layup and ignores free throws entirely. TS% fixes both, which is why analysts, coaches and fantasy players use it to compare a high-volume three-point shooter, a rim-running big and a guard who lives at the free-throw line on equal terms.
Points are calculated from the makes (2 per field goal, plus 1 extra per three, plus 1 per free throw), so the stat line must be internally consistent. The 0.44 free-throw factor is the standard Basketball-Reference and NBA estimate of how many free throws make up one scoring possession.
With the default inputs, the true shooting percentage (ts%) is 64%. Change any value above to recalculate instantly.
How to use the true shooting percentage calculator
- 1Enter total field goals made and attempted (threes included).
- 2Enter three-pointers made and attempted.
- 3Enter free throws made and attempted.
- 4Read TS% for overall scoring efficiency and eFG% for shooting from the field.
Formula and method
True shooting percentage divides points by twice the number of true shooting attempts. True shooting attempts add field goal attempts to 0.44 × free throw attempts — the 0.44 factor approximates how many free throws equal one possession, since and-ones and technical free throws use one shot while most fouls award two or three.
Effective field goal percentage adjusts only for the extra value of a three: each made three counts as 1.5 made field goals. Unlike TS%, eFG% ignores free throws. Points are derived from makes, so a made three contributes 2 (as a field goal) plus 1 extra.

Worked examples
27-point game
9 field goals (3 of them threes) and 6 free throws make 27 points. True shooting attempts are 18 + 0.44 × 7 = 21.08, so TS% = 27 ÷ 42.16 = 64.0%. eFG% counts each three as 1.5 makes: (9 + 1.5) ÷ 18 = 58.3%.
Season of a three-point specialist
400 field goals, 220 threes and 150 free throws total 1,170 points. With 880 + 0.44 × 170 = 954.8 true shooting attempts, TS% = 1,170 ÷ 1,909.6 = 61.3%, well above the 45.5% plain FG%.
Big man who gets to the line but misses free throws
Shooting 8 of 13 from the field is 61.5%, but making only 4 of 10 free throws drags efficiency down: 20 points on 17.4 true shooting attempts is a 57.5% TS%.
Frequently asked questions
How do you calculate true shooting percentage?+
Divide points by 2 × (FGA + 0.44 × FTA). For example, 27 points on 18 field goal attempts and 7 free throw attempts is 27 ÷ (2 × 21.08) = 64.0%.
What is a good true shooting percentage?+
Recent NBA league averages have been around 57–58%. A TS% above 60% is very efficient, and elite high-volume scorers often reach 62–65%. Below about 52% is inefficient at the NBA level.
What is the difference between TS% and eFG%?+
eFG% gives extra credit for threes but ignores free throws. TS% includes free throws as well, so it captures all scoring. A player who draws many fouls will have a TS% noticeably higher than their eFG%.
Why is 0.44 used for free throws?+
Not every free throw attempt is a full possession: two-shot fouls use two attempts, and-ones use one, and three-shot fouls use three. Historical data shows about 0.44 free throw attempts ends one possession on average.
Can true shooting percentage be over 100%?+
Yes, in tiny samples. A player who makes one three-pointer on one attempt has a TS% of 150% because 3 points ÷ (2 × 1) = 1.5. Over a season TS% always lands far below that.
