Basketball True Shooting % Calculator
Compute observed basketball points per two weighted shot-attempt equivalents under caller FT weight; approximation not exact possession tracking or eFG.
Description
True shooting estimates points per two shot-attempt equivalents.
True shooting estimates points per two shot-attempt equivalents. Free-throw weighting is an explicit approximation.1
The returned values include Modeled true shooting percent. The How section below explains the calculation, input rules and interpretation.
When to use Basketball True Shooting % Calculator
Use Basketball True Shooting % Calculator when you need to evaluate the supplied records under the calculation and evidence rules below. No exact possession tracking, eFG replacement or hidden weight is supplied.
Prepare the observed race, match or training records and the stated units. Supply independently verified rule editions, calibration tables and targets where requested.
How to use Basketball True Shooting % Calculator and understand its results
- Prepare the observed race, match or training records and the stated units. Supply independently verified rule editions, calibration tables and targets where requested.
- Enter observedPoints, observedFieldGoalAttempts, observedFreeThrowAttempts, callerFreeThrowPossessionWeight using the field table and calculation rules, then run the tool.
- Read modeledTrueShootingPercent. The explanation below defines the units, signs, ordering and any flags or placeholder values.
- If the tool reports an input issue, correct the values and run it again. Apply the stated assumptions when interpreting a successfully returned result.
| Input field | Meaning | Value type; see rules below | Requirement |
|---|---|---|---|
| observedPoints | Observed points | number | Required |
| observedFieldGoalAttempts | Observed field goal attempts | number | Required |
| observedFreeThrowAttempts | Observed free throw attempts | number | Required |
| callerFreeThrowPossessionWeight | Caller free throw possession weight | number | Required |
Enter integer points/FGA/FTA 0–1000000 and FT fraction 0–1 with positive denominator. Return modeled percentage, which is not clamped.
TS%=100×points/(2×(FGA+FTweight×FTA)) Units, indexing, boundary conditions and exceptional cases are defined in the calculation rules above.
| Output field | Meaning | Value type |
|---|---|---|
| modeledTrueShootingPercent | Modeled true shooting percent | number |
{
"input": {
"observedPoints": 30,
"observedFieldGoalAttempts": 20,
"observedFreeThrowAttempts": 10,
"callerFreeThrowPossessionWeight": 0.44
},
"output": {

}Limitations and assumptions
No exact possession tracking, eFG replacement or hidden weight is supplied.
Numeric inputs, where present, must be finite. Follow the calculation-specific rules for overflow, underflow and exceptional cases. Missing required fields, extra fields, wrong value types and violations of the calculation rules are input errors.
Alternative or Complementary methods
Use Basketball eFG% Calculator: Effective field-goal percentage gives a made three an extra half made-shot equivalent. It excludes free throws. For a complementary task, use Basketball Pace Possession Estimate: A possession estimate combines field goals, weighted free throws, offensive rebounds and turnovers. Pace averages team/opponent estimates before time normalization.
