Winning Percentage Calculator

Enter a team's wins, losses and any ties to compute its winning percentage. Ties count as half a win, and the result is shown in the standard three-digit .XXX form.

How to calculate winning percentage

  1. Enter the number of wins and losses.
  2. Enter ties if your sport allows them, otherwise leave it at zero.
  3. Read the winning percentage as a decimal and as .XXX.

Examples

A 90-72 baseball season

wins 90, losses 72
Winning percentage .556

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.
