Winning Percentage Formulas

When you calculate a winning percentage, you are essentially approximating a ratio of wins versus total attempts. If there were no draws, you simply divide the total number of wins by the number of games that were played, as follows:

Winning Percentage = (Number of Wins / Total Games Played) × 100

Where:

Total Games Played = Number of Wins + Number of Losses

Let's look at an example. Let's say that a basketball team has played 64 games, of which they have won 52. The winning percentage of that basketball team would be as follows:

Winning Percentage = (52 / 64) × 100 = .8125 × 100 = 81.25%

If some games were drawn (i.e., both teams achieved the same score), you would use a different formula that is based on the assumption that a tie represents 0.5 of a win. In such a scenario, you would use the following formula:

Winning Percentage = (2 × Number of Wins + Number of Ties) / (2 × Total Games Played) × 100

Where:

Total Games Played = Number of Wins + Number of Losses + Number of Ties

Example: Let's say our basketball team has played 25 games, of which they have lost 5 and drawn 4. The winning percentage would be determined as follows:

Number of Wins = Total Games Played - Number of Ties - Number of Losses = 25 - 4 - 5 = 16

Winning Percentage = (2 × 16 + 4) / (2 × 25) × 100 = .72 × 100 = 72%
