How do I calculate winning percentage?
Add wins and half the ties, divide by wins plus losses plus ties, then multiply by 100. For ten wins and five losses with no ties, the result is approximately 66.67 percent.
Calculate winning percentage with ties and compare games behind a reference team. See the formula, total games, and the difference between percentage and standings points.
Winning percentage measures the share of games credited as wins. With ties counted as half a win, the formula is wins plus one half of ties, divided by all games played, multiplied by 100. Enter wins, losses, and ties as nonnegative whole numbers. The calculator shows both the percentage and the number of games included. A record of ten wins, five losses, and no ties is 66.67 percent after rounding. The unrounded value is used for the calculation; the display is shortened to make it easier to read.
A tied game belongs in the total number of games and contributes half a win to the numerator. For ten wins, five losses, and one tie, the credited-win total is 10.5 across sixteen games, producing 65.625 percent before display rounding. This convention is common but is not universal across sports. A league may award three points for a win or track overtime outcomes separately. Check the competition rules before treating a generic winning percentage as the official ranking metric.
Games behind compares two win-loss records using half the sum of the leader additional wins and the compared team additional losses. If the reference team has twelve wins and three losses while another has ten wins and five losses, the difference is two games. The two teams need not have played the same total number of games. The formula uses only wins and losses, so ties do not enter this calculation. A negative result means the compared team is ahead of the entered reference rather than behind it.
A team with no wins, losses, or ties has played zero games, so its winning percentage is undefined. The calculator shows No games played instead of assigning a misleading zero percent. A team with one win has 100 percent, but that result says little about long-term strength compared with a team that has played a full season. Always publish the record or sample size alongside the percentage. The same percentage can describe very different amounts of evidence and very different schedules.
Some sports rank by standings points, sets won, goal difference, head-to-head results, or opponent strength. A generic winning percentage does not reproduce those systems. Brackify leaderboards also use their own documented placement-based scoring, rather than converting every tournament finish into a season win percentage. Use this calculator when the win-loss record itself is the relevant comparison. For a league table, apply the published league rules and explain any tiebreak order before participants begin the season.
Count matches or games consistently across every team you compare. A best-of-three set is one match when the league table records match wins, even though it contains two or three individual games. Do not combine game wins for one player with set wins for another. Decide how forfeits, disqualifications, postponed fixtures, and abandoned matches enter the record. Store the original counts so you can recompute the percentage after a correction. Rounding an already rounded percentage back into wins and losses loses information.
Copy the output with its wins, losses, ties, percentage, and games-behind value. Including the raw record helps other people check the arithmetic and avoids arguments caused by display rounding. Use a reference team with a clearly identified record and update both records through the same date. For tournaments, a bracket or Swiss standings table supplies the actual progression; for recurring competitions, the league system maintains the season context. This calculator is a quick arithmetic companion that remains useful without an account or a live data feed.

Not in this calculator. A tie adds one game to the denominator and half a win to the numerator. If your league uses another scoring convention, use its official rules rather than this generic percentage.
Division by zero is undefined. A team that has not played has neither a zero-percent nor a 100-percent record. The tool displays No games played so an empty record is not mistaken for a losing one.
Yes. A negative games-behind value means the entered team is ahead of the reference record under the win-loss formula. The label changes to games ahead so the comparison is easier to understand.
