## Calculator

Value Added (VA) and Estimated Wins Added (EWA) are estimates of how much a player adds to a team’s performance.

Value Added is the estimated number of additional points a player contributes to a team’s season, compared to the number of points a replacement player (often the 12th player on the bench) would contribute.

Estimated Wins Added is similar to Value Added, but for wins. It is the estimated number of additional wins a player contributes to a team’s season, compared to the number of points a replacement player would contribute.

## Formula – How to calculate VA

VA = (Minutes Played x (PER – PRL) ) ÷ 67

Where:

• Minutes Played” is the number of minutes of play the player has recorded.
• PER” is “Player Efficiency Rating” – an overall rating of a player’s per-minute statistical production.
• PRL” is “Position Replacement Level” – what a replacement player (for example the 12th ranking player on the roster) would produce. Power Forwards are 11.5, Point Guards are 11.0, Centers are 10.6, Shooting Guards and Small Forwards are 10.5.

## Formula – How to calculate EWA

EWA = VA ÷ 30

### Example

A player has 2867 minutes played, a PER of 14.22, and plays Point Guard.

VA = (2867 x (14.22 – 11.0)) ÷ 67

VA = (2867 x 3.22) ÷ 67

VA = 9321.74 ÷ 67

VA = 137.79

Therefore, this player is estimated to have contributed 138 points to the team’s season above what a replacement player would contribute.

EWA = 138 ÷ 30

EWA = 4.6

Therefore, this player is estimated to contribute an additional 4.6 wins to the team’s season above what a replacement player would contribute.
