What is Steal Percentage?

Steal percentage is a metric that is intended to highlight the percentage of opponent team possessions that end with a steal by a specific player.

How to calculate Steal Percentage

Steal Percentage is calculated as:
\frac{100 \times \text{Player Steals} \times \text{Team Minutes Played}}{\text{Player Minutes Played}\times\text{Opponent Team Possessions}}


A player has 2 steals and 39 minutes played, on a team that has played 48 minutes. The opposing team has had 94 possessions in this time.
\text{Steal Percentage} = \frac{100 \times 2 \times 48}{39 \times 94}
\text{Steal Percentage} = \frac{9600}{3666}
\text{Steal Percentage} = 0.219
Therefore, this player’s steal percentage would be 0.2619, 2.62% of total opponent possessions.
