Enter makes and attempts from one box score and get true shooting %, effective field goal %, FG%, 3P% and FT% instantly — the efficiency numbers coaches and analysts actually use.
Raw field-goal percentage ignores the extra point on a three and free throws. True shooting folds them in, so it is the fairest single efficiency number.
22 points on 8/17 shooting is a 57.3% true shooting mark.

Both formulas use the numbers from the box above. Worked example for 8/17 from the field, 2/6 from three, 4/5 at the line.
| Stat | Formula | Worked example |
|---|---|---|
| True shooting % (TS%) | PTS ÷ (2 × (FGA + 0.44 × FTA)) | 22 ÷ (2 × 19.2) = 57.3% |
| Effective FG% (eFG%) | (FGM + 0.5 × 3PM) ÷ FGA | (8 + 0.5 × 2) ÷ 17 = 52.9% |
| Points (PTS) | 2 × (FGM − 3PM) + 3 × 3PM + FTM | 2 × 6 + 3 × 2 + 4 = 22 |
The 0.44 in true shooting estimates how many free throws make up one possession — and-ones and three-shot fouls mean a trip to the line is not always two shots. eFG% ignores free throws entirely, which is why TS% is the fuller efficiency number and eFG% is the better measure of shot selection alone. Both are explained in depth in true shooting % explained and effective FG% explained.
| Metric | Solid mark | What it measures |
|---|---|---|
| Field goal % (FG%) | 45%+ | Overall shot accuracy from the floor. |
| Three-point % (3P%) | 35%+ | 35% from three is a genuinely good shooter. |
| Free throw % (FT%) | 75%+ | A reliable free-throw shooter clears 75%. |
| Effective FG% (eFG%) | 50%+ | FG% that credits the extra point a three is worth. |
| True shooting % (TS%) | 55%+ | The best single measure — folds in threes and free throws. |
Field goal percentage is field goals made divided by field goals attempted, times 100. For example, 8 makes on 17 attempts is 8 ÷ 17 = 47.1%. Three-point and free-throw percentages use the same made-over-attempted formula for those shots.
True shooting percentage measures scoring efficiency across all shot types. It is total points divided by 2 × (FGA + 0.44 × FTA). Because it accounts for threes and free throws, TS% is a better efficiency measure than raw field-goal percentage.
Effective field goal percentage adjusts FG% to credit the extra point a made three is worth: (FGM + 0.5 × 3PM) ÷ FGA. A 50% eFG% is roughly average; anything above is efficient.
As a rough guide: 45%+ field goal, 35%+ from three, and 75%+ from the line are good. On the combined measures, an eFG% above 50% and a true shooting percentage above 55% mark an efficient scorer.
