Win Percentage Calculator
Turn a win-loss-tie record into a win percentage — with the right tie convention for your sport.
Three tie conventions
Count ties as half a win, ignore them, or treat them as games with no credit.
Ties change the number
A draw is worth nothing, half a win, or a discarded game depending on the rule you pick.
What is win percentage?
Wins as a share of games played
Win percentage expresses how often a team or player wins, as a percentage of the games that count. At its simplest it is wins divided by games played, times 100. The wrinkle is ties: different sports treat a draw differently, so the same record can produce different win percentages. As references like Wikipedia's article on winning percentage describe, the most common convention in standings counts a tie as half a win — but ignoring ties or counting them as games are both valid depending on the league.
The calculator offers the three standard ways to handle ties, all built on the same wins-over-games idea.
win % = (wins + 0.5 × ties) / (wins + losses + ties) × 100With ties as half a win, each draw adds half a win to the numerator and one game to the denominator — the standard for most standings. Ignoring ties uses only decided games: wins ÷ (wins + losses), which is common where draws are rare or excluded. Counting ties as games with no credit uses wins ÷ all games, treating a draw like a non-win. For a record with no ties, all three give the same answer, so the convention only matters once draws appear.
A team has 30 wins, 18 losses, and 2 ties, and you want the standard standings win percentage.
Credit the ties
Ties as half a win: 30 + (0.5 × 2) = 31 credited wins.Count all games
30 + 18 + 2 = 50 total games.Divide and scale
31 ÷ 50 = 0.62, or 62.0%.Check the alternatives
Ignoring ties gives 30 ÷ 48 = 62.5%; counting ties as games gives 30 ÷ 50 = 60.0%.
The convention you choose should match how your sport or league keeps standings.
Half a win
The default in most standings, including many North American leagues that record ties.
Ignore ties
Best when draws are rare or not part of how the table is ranked — uses only decided games.
As games, no credit
Treats a draw like a non-win; useful when you only reward outright victories.
The win-loss ratio is a different lens: it compares wins directly to losses (for example 30 to 18 is 1.67), ignoring ties entirely. It is handy for a quick sense of dominance, while win percentage is the figure that drives league tables and seedings.
The win percentage is the share of games won under your chosen convention, from 0% (no wins) to 100% (no losses or ties to drag it down). The total games confirms how many results went into the figure, and the win-loss ratio offers a complementary view that sets wins against losses alone. Because ties are handled differently across sports, always compare records using the same convention — a 62.0% under one rule is not directly comparable to a 62.5% under another. For sports without draws, the tie field stays at zero and all three methods agree.
The arithmetic is exact; the convention is a choice.
Match your league's rule
Win percentage only means something when everyone uses the same tie convention, so check how your sport or league defines it before comparing teams. Some leagues weight results differently again — using points systems (such as three points for a win and one for a draw) rather than a percentage — which this calculator does not model. It also treats every game as equal, ignoring strength of schedule, overtime rules, and forfeits. Use it to compute and compare records on a like-for-like basis, not as an official standings engine.
