How to Calculate Winning Percentages

In baseball, a team can either win or lose. During the year, baseball standings provide winning percentage. The winning percentage is the probability a team won a game. For example, if a team had a winning percentage of 0.500 or 50 percent and played 100 games, they won half their games, or 50 games.

Instructions

    • 1

      Add the total amount of games the team won during the year. For example, the team won 80 games.

    • 2

      Add the amount of games played during the course of the season. In the example, the team played 120 games.

    • 3

      Divide the amount of wins by the amount of games played to determine winning percentage. In the example, 80 games divided by 120 games equals a winning percentage of 0.667 or 66.7 percent.
