How to Calculate True Shooting Percentage
True Shooting Percentage (TS%) is a basketball statistic that measures a player's shooting efficiency by accounting for the value of different types of shots. Unlike traditional field goal percentage, TS% considers the extra value of three-pointers and free throws.
TS% Formula:
Step-by-Step Calculation:
- Multiply free throw attempts by 0.44 (accounts for shooting fouls)
- Add this result to field goal attempts
- Multiply the sum by 2
- Divide points scored by this result
- Multiply by 100 to get the percentage
Example:
If a player scores 20 points with 15 field goal attempts and 5 free throw attempts:
TS% = 20 ÷ [2 × (15 + 0.44 × 5)] × 100 = 20 ÷ [2 × 17.2] × 100 = 58.14%
Understanding True Shooting Percentage
What Makes TS% Superior
- ✓ Accounts for the value of three-pointers (worth 1.5x more than two-pointers)
- ✓ Includes free throw efficiency in the calculation
- ✓ Provides a more complete picture of scoring efficiency
- ✓ Better reflects a player's true offensive impact
TS% Benchmarks
TS% vs Other Shooting Metrics
| Metric | What It Measures | Limitations |
|---|---|---|
| Field Goal % | 2-point and 3-point shooting accuracy | Doesn't account for free throws or shot value |
| 3-Point % | Three-point shooting accuracy only | Ignores two-pointers and free throws |
| Free Throw % | Free throw shooting accuracy only | Doesn't reflect overall scoring efficiency |
| True Shooting % | Overall scoring efficiency | None - most comprehensive metric |
Frequently Asked Questions
Why is 0.44 used in the TS% formula?
The 0.44 coefficient accounts for the fact that not all free throw attempts come from shooting fouls. Some free throws result from technical fouls, flagrant fouls, or other situations. This coefficient represents the average proportion of free throws that are directly related to field goal attempts.
What's a good TS% for different positions?
Point guards typically have TS% around 55-58%, shooting guards 55-60%, small forwards 55-59%, power forwards 55-58%, and centers 55-60%. However, elite players at any position can exceed 60% TS%.
How does TS% compare to effective field goal percentage (eFG%)?
eFG% accounts for the extra value of three-pointers but ignores free throws. TS% is more comprehensive as it includes both three-point value and free throw efficiency, making it the superior metric for overall scoring efficiency.
Can TS% be over 100%?
No, TS% cannot exceed 100%. The formula is designed so that 100% represents perfect efficiency where every shot attempt results in the maximum possible points for that type of shot.
