Winning Percentage Calculator

Winning percentage turns a win-loss record into one comparable number, so a 12-4 team and a 30-12 team can be ranked even though they have played a different number of games. The basic version is wins divided by games played. The wrinkle is what to do with ties, and different sports answer that differently.

The standard convention, used in the National Football League (NFL) and most published standings, counts a tie as half a win: percentage equals wins plus half the ties, all divided by total games. So an 8-6-2 team has (8 + 1) divided by 16, which is .563. A second approach simply ignores ties and divides wins by decided games (wins plus losses). A third, stricter approach counts a tie the same as a loss. This calculator lets you pick, because the same record gives three slightly different numbers depending on the rule.

Winning percentage is written as a three-decimal figure with the leading zero dropped, the way baseball does it: .625, not 0.625. Read aloud it becomes “six twenty-five.” A mark of .500 is the break-even line, an equal number of wins and losses. Anything above is a winning record, anything below is a losing one. Teams chasing a playoff spot watch this number more closely than raw win totals, since a club with games in hand can have a worse record but a better percentage. The doughnut below shows your wins, losses, and ties as a share of the season so you can see the split at a glance.
