What is my true shooting percentage?

Type a player’s points, field goal attempts and free throw attempts. The true shooting calculator gives the true shooting percentage (TS%), and the effective field goal percentage (eFG%) when you add makes.

True shooting percentage: 66.9%. 2,375 points on 1,598 field goal and 400 free throw attempts is a true shooting percentage of 66.9%.

How to calculate

Works out a basketball player’s true shooting percentage (TS%) from points, field goal attempts and free throw attempts, with the effective field goal percentage.

Example with the default inputs (Points 2,375, Field goal attempts 1,598, Free throw attempts 400, Field goals made 805, 3-pointers made 402): 2,375 points on 1,598 field goal and 400 free throw attempts is a true shooting percentage of 66.9%.

Method: TSA = FGA + 0.44 × FTA; TS% = PTS ÷ (2 × TSA); eFG% = (FG + 0.5 × 3P) ÷ FGA.

  • The 0.44 free throw factor is the one Basketball-Reference and the NBA use; it counts and-ones and three-shot fouls on average.
  • TS% can pass 100% when most points come from free throws.

How it works

All inputs are whole numbers; the maths is exact.

  • True shooting attempts TSA = FGA + 0.44 × FTA.
  • TS% = PTS ÷ (2 × TSA) × 100%.
  • Points per shooting attempt = PTS ÷ TSA.
  • eFG% = (FG + 0.5 × 3P) ÷ FGA × 100%, shown when you type field goals made and 3-pointers made and FGA is above 0.

Rules

  • FGA and FTA cannot both be 0. Field goals made are at most FGA, and 3-pointers made at most field goals made.

Worked examples by hand

Stephen Curry, 2015-16: 2,375 points, 1,598 FGA, 400 FTA, 805 FG, 402 3P. TSA = 1,598 + 0.44 × 400 = 1,774. TS% = 2,375 ÷ 3,548 = 66.9%. eFG% = (805 + 201) ÷ 1,598 = 63.0%.

30 points, 20 FGA, 10 FTA. TSA = 20 + 4.4 = 24.4. TS% = 30 ÷ 48.8 = 61.5%.

10 points, 0 FGA, 10 FTA. TSA = 4.4. TS% = 10 ÷ 8.8 = 113.6%.

Other questions people ask

What is the true shooting percentage formula?

TS% = points ÷ (2 × (FGA + 0.44 × FTA)). The bracket is the true shooting attempts: field goal attempts plus 0.44 of each free throw attempt.

Why 0.44 for free throws?

Most free throws come in pairs, but and-ones take one and fouls on threes take three. 0.44 is the average share of a shooting possession one free throw attempt uses, as Basketball-Reference and the NBA count it.

What is a good true shooting percentage?

NBA league averages have been in the high 50s in recent seasons. Above 60% is efficient; Stephen Curry’s 2015-16 season was 66.9%.

What is the difference between TS% and eFG%?

eFG% = (FG + 0.5 × 3P) ÷ FGA gives a three its extra point but leaves out free throws. TS% counts every point, free throws included.

Can true shooting be over 100%?

Yes, when most points come from free throws. 10 of 10 free throws and no field goals is 10 ÷ (2 × 4.4) = 113.6%.
