Winning Percentage Calculator
Whether you are tracking a fantasy league, your kid's soccer team, or an MLB pennant race, winning percentage tells you exactly where things stand. Enter your wins, losses, and ties to see your percentage, record, and how far above or below .500 you are.
Winning percentage is calculated as effective wins divided by total games. In its simplest form, that is just wins / (wins + losses). When ties are involved, most leagues count each tie as half a win: (wins + 0.5 * ties) / total games.
In baseball, winning percentage is traditionally displayed as a three-digit decimal like .600 rather than 60%. The NFL also counts ties as half wins since overtime rule changes made ties rare but possible. Soccer and hockey use points systems instead of raw winning percentage, but the underlying win-loss-draw math still applies if you want a simple percentage.
Games over or under .500 tells you how far a team is from a perfectly average record. A team at 60-40 is 10 games over .500 because they would need to lose 10 more games (or win 10 fewer) to reach 50-50. This is a quick way to compare teams that have played different numbers of games.
