Winning Percentage Calculator. Enter your team's wins, losses, and ties to calculate your winning percentage. The calculator applies the standard sports formula — counting ties as half a win — and returns your win percentage, total games played, and a visual breakdown of your record. Also try the ERA Calculator (Baseball).

The standard formula is: Winning Percentage = (Wins + 0.5 × Ties) ÷ Total Games × 100. When there are no ties, it simplifies to Wins ÷ Total Games × 100. The result is typically expressed as a percentage or a decimal between 0 and 1. See also our WAR Calculator (Baseball).
Ties represent a partial success — neither a full win nor a full loss. The convention of counting a tie as 0.5 wins is used in major leagues like the NFL and NHL to fairly credit teams for not losing while not overstating their success. It keeps the winning percentage mathematically balanced.
Simply divide the number of wins by the total number of games played (wins + losses), then multiply by 100. For example, a team with 48 wins and 34 losses has played 82 games, giving a winning percentage of (48 ÷ 82) × 100 = 58.54%.
Multiply the total games by the winning percentage: 15 × 0.40 = 6 wins. So a team with a 40% winning percentage across 15 games won exactly 6 of those games.
It depends on the sport and competition level. In most professional leagues, a winning percentage above 50% (0.500) means a team wins more than it loses, which is generally considered competitive. Elite teams typically maintain 60–70%+ over a full season.
Winning percentage represents wins as a share of all games played (a value from 0% to 100%), while win/loss ratio is simply wins divided by losses (e.g., 2:1 means two wins for every loss). Winning percentage is more commonly used in official standings and statistics.
No. Winning percentage is capped at 100% (or 1.000 in decimal form), which would mean winning every single game played. In practice, very few teams achieve a perfect record over a full season in any sport.
The core formula is the same, but how ties are handled varies. Sports like basketball and baseball rarely have ties, so the simple wins ÷ games formula is used. Sports like American football, hockey, and soccer regularly have draws, so the half-tie adjustment is applied to reflect performance accurately.
