What this Basketball True Shooting Percentage Calculator does
This Basketball True Shooting Percentage Calculator estimates a player’s true shooting percentage, commonly shortened to TS%. It combines points scored with field goal attempts and free throw attempts to express scoring efficiency as a percentage. The worksheet uses the conventional 0.44 weighting for free throw attempts and returns the result to two decimal places.
Enter three totals from the same game, period, or other consistent span: points, field goals attempted (FGA), and free throws attempted (FTA). Points and attempts are counts, so enter whole numbers. The supported range is 0 to 5,000 for points and free throw attempts, and 1 to 5,000 for field goal attempts. The minimum of one FGA keeps the denominator above zero.
The calculator is a limited arithmetic worksheet. It does not check a box score, infer missing statistics, separate made shots, or decide whether the totals describe the same period. Its result is meaningful only when the numbers you enter are coherent and refer to one player and one matching span. It also cannot calculate a line with zero field goal attempts, even if free throw attempts are present.
How to use the Basketball True Shooting Percentage Calculator
Find the player’s points, FGA, and FTA for the period you want to evaluate. Enter each value in its matching field, then calculate the result. A season total, for example, should use season totals for all three inputs. Combining points from one game with attempts from another produces a mathematically valid output that does not describe a valid statistical line.
- Points scored: Enter the player’s total points for the selected period.
- Field goals attempted: Enter FGA for that same period. At least one is required.
- Free throws attempted: Enter FTA for the same period. Zero is allowed.
All three inputs are counts rather than rates, minutes, or decimal percentages. Do not enter field goals made where attempts are requested. The default example uses 30 points, 20 FGA, and 10 FTA. With those values, the calculator reports approximately 61.48%.
How the true shooting percentage formula works
The calculator uses this formula: points ÷ [2 × (field goal attempts + 0.44 × free throw attempts)] × 100. First, it weights free throw attempts by 0.44 and adds that amount to FGA. It then doubles the adjusted attempt total, divides points by that denominator, and multiplies by 100 to express the ratio as a percentage.
For the default example, the calculation is 30 ÷ [2 × (20 + 0.44 × 10)] × 100. The weighted free throw attempts equal 4.4. The adjusted attempt total is therefore 24.4, and twice that amount is 48.8. Dividing 30 by 48.8 and multiplying by 100 gives about 61.48%.
The 0.44 value is a conventional weighting used in this estimated statistic. It accounts for the way free throw trips relate to shooting opportunities in the formula. It is not a count of actual possessions, and the calculator does not reconstruct possession-by-possession play. Results may differ from measures that use other methods or more detailed play data.
There is no 100% ceiling in the formula. A coherent, highly efficient scoring line can produce a TS% above 100%. That result follows from the relationship between points and the weighted attempts, rather than from a percentage cap imposed by this worksheet.
Use cases for the Basketball True Shooting Percentage Calculator
This calculation can help readers summarize scoring efficiency when reviewing a game, comparing a player’s performances across periods, or checking how field goal and free throw attempts relate to points. Since it incorporates free throw attempts alongside field goal attempts, it offers a broader estimate than points per field goal attempt alone.
For a fair comparison, keep the time span and source consistent. A single-game line can be compared with another single-game line, while season totals should be compared with season totals. Context also matters. The statistic summarizes scoring efficiency, but it does not show how a player created shots, how teammates contributed, or what defensive pressure they faced.
It can also serve as a quick arithmetic check when a reader already has a complete line. If the output looks unexpected, verify the three inputs and make sure the totals cover the same period. A typo or mismatched total can change the result substantially, and the tool cannot identify that problem automatically.
Other factors to consider when calculating TS%
True shooting percentage is one compact summary, so it leaves out details that may matter in a fuller evaluation. It does not distinguish two-point attempts from three-point attempts, identify shot locations, show turnovers, or account directly for playing time. It also does not explain whether a player’s scoring volume was high or low. Consider the underlying box score and the comparison you are trying to make alongside the percentage.
The calculator’s input bounds are technical limits for this worksheet, not judgments about what totals are typical. Values within the allowed range can still be inconsistent or incorrect. Check that points, FGA, and FTA belong to the same player and span before interpreting the output. The formula accepts zero points and zero free throw attempts, but it requires at least one field goal attempt to avoid division by zero.
Because 0.44 is a fixed conventional weighting, the calculator cannot adapt it to a specific league, ruleset, or play-by-play record. Treat the answer as an estimate produced by the stated formula. For definitions and statistical context, consult the NBA glossary.
Frequently asked questions
Can true shooting percentage be higher than 100%?
Yes. TS% is not capped at 100% by this formula. A coherent line with exceptionally efficient scoring can produce a result above 100%, because points are divided by the weighted attempt measure.
Why does the calculator require at least one field goal attempt?
The formula divides points by twice the adjusted attempts. With zero FGA and zero FTA, the denominator would be zero. This worksheet sets a minimum of one FGA and does not handle zero-FGA-only lines.
Does 0.44 represent actual possessions?
No. It is the conventional free-throw weighting used in this estimated TS% formula. It helps account for free throw attempts in the calculation, but it does not count actual possessions.
What should I enter for a season calculation?
Use season points, season FGA, and season FTA for the same player and season. Keep the period consistent across all three inputs because the calculator does not validate or reconcile the totals.
Why might my result differ from another source?
Sources can use different data, rounding, or calculation methods. This calculator applies the displayed formula with a fixed 0.44 weighting and shows two decimal places. Check the inputs and the method used by the comparison source.
