Basketball Calculators

  • Assist / Turnover Ratio (AST/TOV) – compares the number of assists a player makes to the number of turnovers committed. A higher ratio indicates better decision-making and effectiveness in facilitating the offense.
  • Assist Ratio – the percentage of a player’s possessions that result in an assist. A higher assist ratio indicates a player’s effectiveness in creating scoring opportunities for teammates.
  • Defensive Rebound Percentage (DRB%) – the percentage of available defensive rebounds a player secures. A higher percentage indicates greater effectiveness in limiting second-chance opportunities for the opposing team.
  • Efficiency (EFF) – a player’s overall performance by combining various contributions, such as points, rebounds, assists, steals, and blocks, while subtracting turnovers and missed shots. A higher EFF indicates a more impactful performance.
  • Effective Field Goal Percentage (eFG%) – adjusts shooting efficiency by accounting for the extra value of three-pointers. It’s calculated by adding half the number of three-pointers made to total field goals made, divided by total attempts. A higher eFG% indicates better scoring efficiency.
  • Estimated Wins Added (EWA) – the number of additional wins a player contributes to their team compared to a replacement-level player. A higher EWA indicates a more valuable player.
  • Field Goal Percentage (FG%) – measures a player’s shooting efficiency by calculating the ratio of successful field goals to total attempts. A higher FG% indicates better scoring accuracy.
  • Free Throw Percentage (FT%) – a player’s accuracy at the free-throw line, calculated by the ratio of successful free throws to total attempts. A higher FT% indicates greater reliability in scoring from the line.
  • Floor Percentage – measures the effectiveness of a player’s shooting during possessions that end in a field goal attempt. A higher floor percentage indicates better scoring efficiency.
  • Game Score (GmSc) – evaluates a player’s performance in a single game by combining various statistics into a single number. A higher game score reflects a more impactful performance.
  • Offensive Rebound Percentage (ORB%) – the percentage of available offensive rebounds a player secures. A higher percentage indicates greater effectiveness in gaining second-chance opportunities for scoring.
  • Pace Factor – measures the number of possessions a team has per game, indicating the tempo of play. A higher pace factor suggests a faster style of play with more scoring opportunities.
  • Performance Index Rating (PIR) – evaluates a player’s overall impact in a game by aggregating various statistics. A higher PIR indicates a more significant contribution to the team’s performance.
  • Points per Possession (PPP) – measures offensive efficiency by calculating the average points scored per possession. A higher PPP indicates a more effective offense.
  • Pythagorean Win Percentage – estimates a team’s expected winning percentage based on points scored and allowed. It provides a better assessment of team performance than win-loss records alone, with a higher percentage indicating a stronger team.
  • Rebound Rate – the percentage of available rebounds a player secures while on the court, combining offensive and defensive rebounds. A higher rebound rate indicates greater effectiveness in gaining possession for the team.
  • Safe Lead – a point margin (often around 10 points) that is considered secure enough to maintain control of the game, reducing the risk of a late comeback by the opposing team.
  • Steal Percentage (STL%) – the rate at which a player records steals during defensive possessions. It’s calculated by dividing the number of steals by the total defensive possessions. A higher steal percentage indicates a player’s effectiveness in disrupting the opposing team’s offense.
  • Steal / Turnover Ratio (STL/TOV) – compares the number of steals a player records to the number of turnovers they commit. A higher ratio indicates a player is effective at creating defensive opportunities while minimizing mistakes on offense.
  • Team Possessions – This is kind of embarrassing, but we have no idea where this formula came from. It’s a calculator we made a while ago and forgot the source of it. We keep it around because people keep using it.
  • Total Rebound Percentage – the percentage of available rebounds a player secures, combining both offensive and defensive rebounds. It’s calculated by dividing the total rebounds by the total number of available rebounds. A higher percentage indicates greater effectiveness in rebounding.
  • True Shooting Percentage (TS%) – measures a player’s scoring efficiency by accounting for field goals, three-pointers, and free throws. It’s calculated by dividing total points scored by twice the total number of field goal attempts plus total free throws. A higher TS% indicates better scoring efficiency.
  • Turnover Percentage (TOV%) – the rate at which a player commits turnovers relative to their total possessions. It’s calculated by dividing the number of turnovers by the total number of possessions. A lower turnover percentage indicates better ball control and decision-making.
  • Usage Rate (USG) – the percentage of a team’s offensive plays that a player is involved in while on the court. It reflects how much a player is relied upon for scoring and creating plays. A higher usage rate indicates a significant role in the team’s offense.
  • Value Added (VA) – measures a player’s overall impact on their team’s performance by estimating the number of additional wins they contribute compared to a replacement-level player. It takes into account various statistics, providing a comprehensive view of a player’s contribution to the team’s success.
