What is PDO (SPSV%)?

PDO (or SPSV%) is the sum of a team’s shooting percentage and save percentage when both teams are at even strength.

PDO is based on the theory that team will regress to a PDO of 100%. A team with a PDO of more than 100% is seen as performing better than they actually are (and due for a bad luck streak). A team with a PDO of less than 100% may be performing worse than they actually are (and due for a lucky streak).

A player’s PDO is calculated using only the time they are on the ice. A team’s PDO is calculated for the entire team’s performance.

Formula

PDO = Team’s Shooting Percentage + Team’s Save Percentage

  • Shooting Percentage” is the percentage of shots a team makes that count as goals. Do not include statistics from a shootout.
  • Save Percentage” is the percentage of saves a team makes. Include empty net statistics (unlike calculating a goalie’s save percentage). Do not include statistics from a shootout.

Example

A team has a shooting percentage of 11.2% and a save percentage of 87.3%.

PDO = 11.2% + 87.3%
PDO = 98.5%

This team’s PDO would be 98.5%, or 0.985
