What Is a TS Calculator?

A TS calculator turns a basketball box score into a single efficiency number called true shooting percentage, shortened to TS%. The metric was popularised by the Association for Professional Basketball Research Metrics and is one of the most cited shooting statistics across the NBA, college basketball, and amateur leagues.

  • Evaluating NBA players: Compare a guard or big against the league-wide TS% benchmarks without being misled by free throws and three-pointers.
  • Scouting college and amateur players: Translate a college box score into the same TS% number used in the pros so prospects can be compared on a level scale.
  • Fantasy and betting prep: Add a TS% layer to fantasy or betting analysis so a hot scoring streak can be checked against actual shot quality.
  • Coaching shot selection: Show a player or team how often a two-point jumper, three-pointer, or trip to the line actually moves the efficiency needle.

Traditional field goal percentage treats every shot the same, which is why the league moved to effective field goal percentage and then to true shooting percentage. TS% weights the points scored by the possessions used, so a three-pointer counts for more than a two-pointer and free throws are credited at roughly the right value.

The tool is most useful when the user has a box score in hand. Three numbers go in: total points, total field goal attempts, and total free throw attempts. Three numbers come out: TS%, TSA, and an efficiency tier.

When the tool surfaces a strong percentage and the next question is how the player contributed in rebounds, assists, and turnovers, Basketball PER Calculator turns the rest of the box score into a single per-minute efficiency number.

How the True Shooting Formula Works

The TS calculator applies the two-step true shooting formula. First it builds a true shooting attempts total from the field goal attempts and the free throw attempts, and then it divides the points scored by twice that total to produce the percentage.

TS% = Points / (2 x (FGA + 0.44 x FTA))
  • Points: The PTS column from the box score. Use the period you want to evaluate, such as a single game, a playoff series, or a full season.
  • FGA: Field goal attempts, including both two-pointers and three-pointers. And-ones that finish with a made basket still count as one attempt.
  • FTA: Free throw attempts. The TSA term multiplies FTA by the 0.44 possession weighting to convert attempts into possession-equivalent units.
  • 0.44 weighting: The possession weighting constant that turns free throw attempts into a possession-equivalent number, since the average free throw trip uses about 0.88 of a field goal possession.

The numeric answer is a single percentage, but the supporting TSA value tells the user how many possession-equivalent attempts the percentage was built on. A 62 percent TS% on 200 TSA is far more meaningful than 62 percent on 5.

Worked Example: 1,295 Points, 850 FGA, 420 FTA

1,295 points across 850 field goal attempts and 420 free throw attempts.

TSA = 850 + (0.44 x 420) = 1,034.8. TS% = 1,295 / (2 x 1,034.8) = 1,295 / 2,069.6 = 0.6257.

62.57 percent true shooting percentage

Falls into the Great band and is close to the career TS% of several Hall of Fame forwards.

Worked Example: 1,500 Points, 1,000 FGA, 300 FTA

A high-volume three-point shooter scoring 1,500 points on 1,000 field goal attempts and 300 free throw attempts.

TSA = 1,000 + (0.44 x 300) = 1,132. TS% = 1,500 / (2 x 1,132) = 1,500 / 2,264 = 0.6625.

66.25 percent true shooting percentage

Crosses the elite 65 percent line, the kind of line typical for a high-volume three-point shooter who also draws enough free throws to keep the FTA multiplier working.

According to Basketball Reference glossary, true shooting percentage is points divided by twice the sum of field goal attempts and 0.44 times free throw attempts, and it remains one of the most cited single-number shooting metrics in basketball.

When a high TS% is driven by layups and dunks at the rim rather than three-pointers, Dunk Calculator shows how the player's height, reach, and vertical combine into the rim clearance needed to keep that shot diet going.

Key Concepts Behind True Shooting Percentage

The TS% formula looks simple, but the four pieces that feed it each carry a specific meaning.

True shooting attempts

TSA is the denominator of the TS% formula. Each free throw attempt is weighted as 0.44 of a possession, an APBRmetrics value based on how many field goal possessions an average free throw trip replaces.

The 0.44 free throw weight

The 0.44 constant is the formula's key number. It is a possession weighting, not a points value: an average free throw trip uses about 0.88 of a field goal possession, so each FTA counts as roughly 0.44 of a possession in the TSA denominator.

Why three-pointers matter

A made three-pointer adds 50 percent more points than a made two-pointer, but both still cost one field goal attempt. TS% is one of the few standard metrics that captures that extra value, which is why high-volume three-point shooters tend to lead the league.

TS% versus effective field goal percentage

Effective field goal percentage (eFG%) adjusts for three-pointers but ignores free throws. TS% adds the free throw component, which is why a foul-drawing big man can post a higher TS% than a shooter with a similar eFG%.

These four concepts feed each other. The 0.44 weight lines up the TSA denominator with the points numerator for a fair single-number summary of shot efficiency.

When the key concept discussion turns to shot quality at the rim and how rim pressure feeds the percentage, Vertical Leap Calculator pairs the TS% reading with the jump height and power number that often backs it up.

How to Use This True Shooting Tool

The calculator is built around three box-score counts. Pull them from any source you trust and paste them in for a real-time result.

  1. 1 Pull the PTS, FGA, and FTA totals: Open the box score, season log, or scouting report and copy the points, field goal attempts, and free throw attempts. Choose the window you want to evaluate, such as a single game, a series, or a season.
  2. 2 Enter the three numbers: Type the points value into the first box, the field goal attempts into the second, and the free throw attempts into the third. The FGA box must be at least 1 to avoid a divide-by-zero in the TS% step.
  3. 3 Read the TS% and TSA together: The percentage is the headline output, but the TSA value below it tells you how many possession-equivalent attempts the percentage was built on. A small sample is interesting, a large sample is meaningful.
  4. 4 Check the efficiency tier: Compare the percentage against the Elite (65%+), Great (60-64.99%), Average (57-59.99%), Below Average (53-56.99%), and Poor (under 53%) bands the calculator displays. The tier label gives a quick read of how the player stacks up against modern NBA benchmarks.
  5. 5 Use the Reset button to start over: Press Reset to return to the worked-example defaults (1,295 points, 850 FGA, 420 FTA) and start a new comparison.

A coach types in 2,000 points, 1,600 FGA, and 600 FTA. The TS% lands at 53.65 percent in the Below Average band, which tells the coach the player is taking too many mid-range shots for the modern league.

When a coach wants to round out a player's TS% scouting profile with a court-speed number, Sprint Speed Calculator turns 40-yard and three-quarter sprint times into the meters-per-second number that sits alongside TS% on a recruiting sheet.

Benefits of Using This True Shooting Tool

TS% is one of the few basketball metrics that captures what a player did on offense in a single number. The calculator makes that number reproducible and comparable across leagues.

  • Three numbers in, one answer out: Pulls the three box-score counts you already collect and returns a percentage in the same units a coach would write on a clipboard.
  • Cross-league comparability: Translates a college, G-League, or international stat line into the same TS% scale the NBA uses, so a prospect can be evaluated without rescaling.
  • Free throw value is built in: Unlike raw field goal percentage, the 0.44 weighting means a trip to the line moves the needle, which is useful for big men and slashing guards.
  • Sample size visibility: Surfaces the true shooting attempts alongside the percentage so a small sample can be flagged as small instead of being mistaken for a real result.
  • Coaching and shot-selection feedback: Lets a coach and player run what-if scenarios quickly so a shot diet can be discussed with the same numbers the league uses.

The biggest benefit of using the TS calculator is that it removes the friction from using one of basketball's most-cited statistics. Once the percentage is on screen, the user can paste it into a scouting report, a fantasy spreadsheet, or a conversation with a coach.

Factors That Affect TS% Results

Several variables move a TS% number up or down. Knowing which ones are in play keeps the percentage from being read in isolation.

Three-point attempt rate

A higher share of three-point attempts pushes TS% up because a made three adds 50 percent more points than a made two-pointer, with the same FGA cost.

Free throw attempt rate and accuracy

Players who draw fouls and convert free throws at a high rate see the FTA term carry more weight in the denominator, which lifts the percentage.

Sample size and minutes played

TS% is most reliable over large samples. A 65 percent line on 50 TSA is interesting, while a 65 percent line on 1,000 TSA is a season-defining result.

Role and shot diet

A centre who lives at the rim and a stretch five who lives behind the arc will post different TS% ranges, and the tier bands are a rough guide rather than a fixed scale.

  • TS% does not separate team context from individual skill. A player who plays next to multiple playmakers can post a higher TS% than the same player would in isolation.
  • The 0.44 free throw weight is a league-average possession estimate. For a player who lives at the line, a team-specific constant can be more accurate, but the standard 0.44 keeps the metric comparable across the league.

Reading TS% alongside usage rate, assist rate, and pace gives the full picture. The tool focuses on the shooting number so it pairs with the rest of a scouting workflow without doubling up on inputs.

According to Wikipedia - True shooting percentage, the metric was popularized by the Association for Professional Basketball Research Metrics and the 0.44 weighting reflects that an average free throw trip uses about 0.88 of a field goal possession, which is why TS% is one of the standard advanced basketball statistics.

When the factors section breaks down how shot diet and role move TS%, Sport Calorie Burn Calculator estimates the energy cost of a basketball training session so offensive efficiency and conditioning load can sit on the same scouting sheet.

Frequently Asked Questions

Q: What is a TS calculator used for?

A: A true shooting calculator converts a basketball box score into a true shooting percentage. You enter points scored, field goal attempts, and free throw attempts, and the tool returns TS%, true shooting attempts, and an efficiency tier.

Q: How do you calculate true shooting percentage?

A: Calculate true shooting attempts as field goal attempts plus 0.44 times free throw attempts. Divide the points scored by twice that total, and multiply by 100 to get the percentage. The TS calculator does this in real time.

Q: What is a good TS% in the NBA?

A: Modern NBA league average TS% sits in the high 50s, typically around 57 to 58 percent. Anything from 60 percent up is in the Great band, and 65 percent or higher is the Elite band where top scorers like Stephen Curry and Kevin Durant post their seasons.

Q: How does true shooting percentage differ from effective field goal percentage?

A: Effective field goal percentage adjusts for three-pointers but ignores free throws. True shooting percentage adds the free throw component with the 0.44 weighting, which is why TS% is a better single-number summary of overall efficiency.

Q: What counts as a true shooting attempt?

A: A true shooting attempt is one field goal attempt plus 0.44 of one free throw attempt. The 0.44 constant is a possession weighting, not a points value. It reflects that the average free throw trip uses about 0.88 of a field goal possession, so each free throw attempt counts as roughly 0.44 of a possession in the TSA denominator.

Q: Can the true shooting percentage exceed 100 percent?

A: In practice the percentage can occasionally nudge above 100 percent when a stat line is logged with and-ones that are double-counted, which is why the tool caps the displayed value at 100 percent to keep the tier label honest.
