What is True Shooting Percentage (TS%)?

True Shooting Percentage (TS%) is a basketball statistic that measures a player's overall shooting efficiency. Unlike traditional field goal percentage (FG%), which only considers made shots out of attempted shots, TS% incorporates 1-point (free throws), 2-point, and 3-point field goals. This provides a more comprehensive and accurate picture of how efficiently a player converts scoring opportunities into points.

Who Should Use It: True Shooting Percentage is valuable for players, coaches, analysts, and fans who want to go beyond basic shooting metrics. It's particularly useful when comparing players with different scoring styles, such as those who draw a lot of fouls versus those who primarily shoot from the perimeter.

Common Misunderstandings: A frequent misunderstanding revolves around the "2 * (FGA + 0.44 * FTA)" denominator. This part of the formula is designed to estimate the total number of scoring possessions a player uses. Field goal attempts (FGA) are counted as one possession each. Free throw attempts (FTA) are weighted at 0.44 because, historically, a free throw attempt is equivalent to about 0.44 scoring possessions on average. This normalization allows for a fair comparison of shooting efficiency across different types of scoring actions.

True Shooting Percentage Formula and Explanation

The formula for True Shooting Percentage is:

TS% = Total Points / (2 * (FGA + 0.44 * FTA))

Let's break down the components:

Formula Variables and Units

Variable	Meaning	Unit	Typical Range
FGM	Field Goals Made	Count	0 – 1000+ (per season)
3PM	3-Pointers Made	Count	0 – 500+ (per season)
FTM	Free Throws Made	Count	0 – 500+ (per season)
FGA	Field Goals Attempted	Count	0 – 1500+ (per season)
FTA	Free Throws Attempted	Count	0 – 700+ (per season)
Total Points	Calculated as (FGM * 2) + (3PM * 3) + FTM. Note: Some definitions simply use a provided "Total Points" value, but for clarity and completeness, we calculate it here from its components.	Points	0 – 3000+ (per season)
TS%	True Shooting Percentage	Percentage (%)	40% – 70%+ (Elite players often exceed 60%)

The denominator, 2 * (FGA + 0.44 * FTA), is crucial. It attempts to quantify the total number of scoring possessions a player uses. Each field goal attempt (FGA) is one possession. Free throws are more complex; while each made free throw is 1 point, each *attempt* is considered to be 0.44 of a possession on average. Multiplying the total possessions by 2 converts the total points into a points-per-possession metric, which is then expressed as a percentage for easier comparison.

Practical Examples

Example 1: Efficient Scorer

Player A had a strong offensive season:

• Field Goals Made (FGM): 400
• 3-Pointers Made (3PM): 120
• Free Throws Made (FTM): 180
• Field Goals Attempted (FGA): 800
• Free Throws Attempted (FTA): 240

Calculation:

• Total Points = (400 * 2) + (120 * 3) + 180 = 800 + 360 + 180 = 1340 points
• Possessions = 2 * (800 + 0.44 * 240) = 2 * (800 + 105.6) = 2 * 905.6 = 1811.2 possessions
• TS% = 1340 / 1811.2 = 0.7397… or 74.0%

Player A demonstrates elite efficiency with a 74.0% True Shooting Percentage.

Example 2: High Volume, Lower Efficiency

Player B is a high-volume scorer who relies more on volume than efficiency:

• Field Goals Made (FGM): 500
• 3-Pointers Made (3PM): 50
• Free Throws Made (FTM): 100
• Field Goals Attempted (FGA): 1200
• Free Throws Attempted (FTA): 150

Calculation:

• Total Points = (500 * 2) + (50 * 3) + 100 = 1000 + 150 + 100 = 1250 points
• Possessions = 2 * (1200 + 0.44 * 150) = 2 * (1200 + 66) = 2 * 1266 = 2532 possessions
• TS% = 1250 / 2532 = 0.4936… or 49.4%

Player B has a significantly lower True Shooting Percentage of 49.4%, highlighting that while they score a lot of points (500 FGM * 2 pts/FGM + 50 3PM * 3 pts/3PM + 100 FTM), they do so less efficiently per scoring opportunity compared to Player A. This example shows the value of the true shooting calculator in discerning efficiency from raw scoring output.

Key Factors That Affect True Shooting Percentage

Several factors contribute to a player's True Shooting Percentage, influencing their efficiency on the court. Understanding these can help players and coaches identify areas for improvement:

1. Shot Selection: Players who consistently take high-percentage shots (e.g., layups, dunks, open mid-range jumpers) will naturally have a higher TS%. Taking too many contested shots or low-percentage threes can decrease efficiency.
2. 3-Point Shooting Volume & Accuracy: While 3-pointers are worth more points, a low accuracy rate can drag down TS%. A player needs to be reasonably accurate from beyond the arc for it to be an efficient scoring method. High volume 3P% is key.
3. Free Throw Rate & Accuracy: Players who draw a lot of fouls (high FTA) and convert a high percentage of their free throws can significantly boost their TS%. Free throws are the most efficient scoring play in basketball (1 point per attempt on average, worth more than a 2-point FG if accuracy is high).
4. Shot Quality & Defense: The quality of shots generated (open looks vs. contested) and the effectiveness of opposing defenses play a role. Players who can create good shots for themselves or their teammates often have higher TS%.
5. Offensive System: The team's offensive strategy can impact a player's efficiency. Systems that generate open looks or prioritize efficient scoring can help boost a player's TS%.
6. Shot Type Mix: The balance between 2-pointers, 3-pointers, and free throws affects the overall calculation. A player scoring exclusively via layups might have a very high TS%, while a player taking many contested threes might have a lower one, even with similar scoring volume. The 0.44 factor in the formula helps normalize these differences.

Frequently Asked Questions (FAQ)

What is considered a good True Shooting Percentage?

Generally, a TS% above 60% is considered excellent. League averages typically hover around 55-58%. Elite scorers often achieve 60-65% or higher. Anything below 50% might indicate inefficient scoring relative to opportunities.

How does TS% differ from FG%?

Field Goal Percentage (FG%) only measures the efficiency of 2-point and 3-point shots made out of attempts. True Shooting Percentage (TS%) is more comprehensive, factoring in the point value of 3-pointers and the efficiency of free throws, providing a more accurate overall shooting efficiency metric.

Is the 0.44 FTA multiplier always accurate?

The 0.44 is a widely accepted statistical average representing the number of possessions used per free throw attempt. While it's a simplification, it provides a robust basis for comparing efficiency across different player styles and eras. Some analytics prefer variations, but 0.44 is standard for TS%.

Can TS% be over 100%?

No, True Shooting Percentage cannot be over 100%. It's a ratio of points scored to weighted scoring possessions. The maximum points a player could score per possession would be 3 (a 3-pointer) plus the value of free throws if fouled on the play. The formula ensures the percentage stays within a realistic range.

Should I use season totals or per-game averages for the calculator?

The calculator works with raw counts. For season or career analysis, use season/career totals. For game-specific analysis, use game totals. Ensure consistency in the data you input. The resulting TS% will reflect the efficiency for that specific dataset.

Does TS% account for turnovers?

No, the standard True Shooting Percentage formula does not directly account for turnovers. It focuses solely on shooting efficiency from field goals and free throws. Other metrics like Usage Percentage might consider turnovers as part of overall offensive possessions.

How do I calculate Total Points if it's not given?

If you have FGM, 3PM, and FTM, you can calculate total points: Total Points = (FGM * 2) + (3PM * 3) + FTM. Some advanced stats providers might list total points directly, but calculating it ensures accuracy with the specific shot counts.

What is the difference between "Field Goals Made" and "Total Points"?

"Field Goals Made" (FGM) refers only to the number of successful shots taken from the field (2-pointers and 3-pointers). "Total Points" is the sum of points from all scoring sources: 2-point field goals, 3-point field goals, and free throws.
