Definition – What is “Assist Ratio”?
Assist ratio is a measurement of how frequently a team uses assists to contribute to offense.
A team with a high assist ratio is more likely to score using an assist than a team that does not. Teams with a high assist ratio are more likely to pass and work together. Teams with a low assist ratio are more likely to have a small number of stars who play on their own.
The statistic is credited to basketball statistician John Hollinger.
Formula – How to calculate Assist Ratio
Assist Ratio = (AST ÷ (FGA + (0.44 x FTA) + AST + TO)) x 100%
Where:
- “AST” are assists.
- “FGA” are field goal attempts.
- “FTA” are free throw attempts.
- “TO” are turnovers.
Example
A team has 586 assists, 1909 field goal attempts, 858 free throw attempts, and 387 turnovers.
Assist Ratio = (586 ÷ (1909 + (0.44 x 858) + 586 + 387)) x 100%
Assist Ratio = (586 ÷ (1909 + 377.52 + 586 + 387)) x 100%
Assist Ratio = (586 ÷ 3259.52) x 100%
Assist Ratio = 0.1798 x 100%
Assist Ratio = 17.98%
