True Shooting Percentage Calculator
Measure scoring efficiency with points, field goal attempts, and free throws.
What it does
True shooting percentage measures how efficiently a basketball player turns shooting opportunities into points. It includes two-point field goals, three-point field goals, and free throws, so it is broader than ordinary field goal percentage.
The formula divides points by twice the estimated number of shooting attempts. Field goal attempts count once. Free throw attempts count 0.44 times because not every free throw uses a full possession, and some trips produce two or three attempts.
This calculator reports TS%, the estimated true shot attempts, and points per attempt. The extra figures make the math easier to check and help compare a high-volume scorer with a player who takes fewer shots but earns more free throws.
TS% is a scoring metric, not a complete offensive rating. It does not include turnovers, offensive rebounds, assists, screening, or shot difficulty. The 0.44 multiplier is an estimate, and league context matters. Use it with usage rate and role in mind.
How to use
- Enter total points scored.
- Enter field goal attempts, including both two-point and three-point attempts.
- Enter free throw attempts.
- Read the true shooting percentage.
- Check the estimated true attempts and points per attempt.
- Compare players with similar roles and era rather than across every style.
Formula
- PTS
- Total points scored.
- FGA
- Field goal attempts, including twos and threes.
- FTA
- Free throw attempts.
- 0.44
- Estimated possessions used per free throw attempt.
The multiplier 0.44 is a convention, not an exact count. Some analysts adjust it for technical free throws or and-one situations. A player with no free throw attempts still gets a valid result from field goals alone. The denominator uses 2 because a made field goal is worth two points before the extra point for a three.
Worked example
Example: 30 points on 20 FGA and 8 FTA
Points 30, field goal attempts 20, free throw attempts 8.
- Free throw equivalent: 0.44 x 8 = 3.52.
- True attempts: 20 + 3.52 = 23.52.
- Denominator: 2 x 23.52 = 47.04.
- TS%: 30 / 47.04 x 100 = 63.8 %.
- Points per attempt: 30 / 23.52 = 1.276.
- The tool shows 63.8 %, 23.52 true attempts, and 1.276 points per attempt.
Reference table
| Points | FGA | FTA | TS% |
|---|---|---|---|
| 25 | 18 | 6 | 60.6 % |
| 30 | 20 | 8 | 63.8 % |
| 35 | 25 | 6 | 63.3 % |
| 40 | 30 | 10 | 58.1 % |
| 12 | 10 | 0 | 60.0 % |
Limits
- The 0.44 free throw multiplier is an estimate, not a possession count.
- Turnovers and offensive rebounds are not included.
- The metric does not measure defense, passing, or shot difficulty.
- Small samples and different eras can make comparisons misleading.
Common mistakes
- Using made field goals instead of field goal attempts.
- Leaving free throw attempts out of the denominator.
- Treating TS% as a percentage of shots made.
- Using 0.5 instead of 0.44 for free throw attempts.
- Comparing a high-usage scorer with a low-usage finisher without context.

Questions
What is a good true shooting percentage?
NBA league averages usually sit in the mid to high 50s. A mark above 60% is strong, but role, era, and shot diet matter.
Why does the formula use 0.44?
It estimates how many possessions a free throw attempt uses. A two-shot trip is one possession, so each attempt is about half a possession, with adjustments for and-ones and technicals.
Does TS% include three-pointers?
Yes. Points include threes, and field goal attempts include three-point attempts. That is one reason TS% is more complete than FG%.
Is TS% better than field goal percentage?
It is better for scoring efficiency because it includes threes and free throws. It still ignores turnovers and other parts of offense.
Can TS% be above 100%?
Yes. A player can score more than two points per true attempt by making threes and free throws, so the percentage can exceed 100.
Are technical free throws included?
This calculator uses all free throw attempts you enter. Some analysts remove technical free throws before calculating TS%.
