Winning percentage

In sports, a winning percentage is the fraction of games or matches a team or individual has won. It is equal to wins divided by wins plus losses. Winning percentage is one way to compare the record of two teams; however, another standard method most frequently used in baseball and professional basketball standings is games behind.


 * $$\mathrm{Winning}\ \mathrm{percentage} = \frac{\mathrm{Wins}}{\mathrm{Total}\ \mathrm{games}}$$

Ties count as a game and should be calculated as neither a loss nor a tie.

National Hockey League
In ice hockey, standings are determined by points, not wins, changing the nature of this statistic. In the National Hockey League, teams are awarded two points for a win, and one point for either a tie (a discontinued statistic) or an overtime loss. Since this calculation is not based solely on wins, the statistic is called points percentage. It can be calculated as follows:


 * $$\mathrm{Points}\ \mathrm{percentage} = \frac{\mathrm{Points}}{\mathrm{Total}\ \mathrm{possible}\ \mathrm{points}}$$
