How to calculate winning percentage

- Enter ties if your sport allows them, otherwise leave it at zero.

Frequently asked questions
How is winning percentage calculated?
Winning percentage is wins plus half of ties, divided by total games played. With no ties it simplifies to wins divided by games played. For example, a 90-72 record is 90 / 162 = .556.
How are ties handled?
A tie counts as half a win. So a 10-5-1 record is (10 + 0.5) / 16 = 10.5 / 16 = .656. Sports without ties simply use wins divided by games played.
Why is the result shown without a leading zero?
Like batting average, winning percentage is written without the leading zero, so 0.556 becomes .556. This tool follows that convention and rounds to three decimal places.
How are games behind related to winning percentage?
Games behind compares two records directly and is not the same as winning percentage, though the two move together. This tool reports winning percentage, which ranks teams regardless of how many games they have played.
Can winning percentage be exactly .500?
Yes. An equal number of wins and losses with no ties gives .500. Counting ties as half a win can also land a team at .500, for example a 4-4-2 record.
