Win Shares
A precise tool.
What is the Win Shares & How does it work?
Win Shares (WS) is a metric that estimates the number of wins a player contributes to his team. It aggregates a player’s offensive and defensive contributions into a single value, allowing comparisons across positions and eras. The calculation starts by summing a player’s basic box‑score stats—points, rebounds, assists, steals, and blocks—then subtracts the negative impacts such as missed shots and turnovers. This raw contribution is then scaled by the team’s success rate and the player’s share of total minutes. Because the formula ties individual performance to team outcomes, Win Shares provides a balanced view of a player’s value, rewarding both personal efficiency and the ability to help the team win games.
WS = left[ (PTS + REB + AST + STL + BLK) – (FGA – FGM) – (FTA – FTM) – TO right] times frac{Team Wins}{Team Games} times frac{Minutes Played}{Team Minutes}
PTS = points, REB = rebounds, AST = assists, STL = steals, BLK = blocks, FGA = field‑goal attempts, FGM = field‑goals made, FTA = free‑throw attempts, FTM = free‑throws made, TO = turnovers

Why is it important to subtract negative impacts like missed shots and turnovers?
Subtracting negative impacts provides a more accurate picture of a player’s net contribution to their team’s success.
How can I interpret the Win Shares value once calculated?
A higher Win Shares value indicates that the player has contributed more wins to their team compared to other players on the same team.
Is there a way to compare Win Shares across different eras or positions?
Yes, Win Shares is designed to aggregate contributions from various aspects of play and can be used to make comparisons across different eras and positions in basketball.
