How it works
Winning percentage summarizes a team's success in a single figure, and this calculator computes it from wins, losses, and ties. You enter the number of wins, losses, and ties, and it returns the winning percentage both as the traditional three-decimal figure, like .625, and as a normal percentage. The calculation divides wins by total games, with ties counted as half a win since they fall between a win and a loss. This standard treatment lets you compare teams that have played different numbers of games, because it expresses success as a rate rather than a raw count. In sports that report standings, winning percentage is the usual basis for ranking, and it is conventionally displayed to three decimal places, so a team that wins ten of sixteen games has a .625 winning percentage. Many sports have no ties, in which case the formula simplifies to wins divided by wins plus losses. A winning percentage of .500 means an even record, above .500 is a winning record, and below is a losing one. Coaches, fans, and analysts use it to gauge performance, seed playoffs, and compare seasons. Enter the wins, losses, and any ties to compute the winning percentage.
Win% = (wins + 0.5 × ties) / total games
Winning percentage divides wins, with each tie counted as half a win, by the total number of games played. Ties count as half because they are neither a full win nor a full loss. The result is usually shown as a three-decimal figure such as .625, and it lets teams with different numbers of games be ranked fairly.

Frequently asked questions
How do you calculate winning percentage?
Divide wins by total games played, counting each tie as half a win. For a 10-6 record with no ties, that is 10 divided by 16, or .625. The calculator returns this both as the traditional three-decimal figure and as a normal percentage when you enter wins, losses, and ties.
Why do ties count as half a win?
A tie is neither a win nor a loss, so counting it as half a win places it exactly between the two, which is the fair and standard convention. This keeps winning percentage consistent: a team that ties every game finishes at exactly .500, reflecting an even outcome across its schedule.
Why is winning percentage shown to three decimals?
By long-standing convention, sports display winning percentage to three decimal places, such as .625, often read aloud without the decimal point. This precision distinguishes teams with similar records over long seasons, where small differences in winning percentage can decide standings and playoff seeding, making the extra digits meaningful.
What if my sport has no ties?
If ties are impossible in your sport, simply enter zero for ties, and the formula reduces to wins divided by the sum of wins and losses. The calculator handles this automatically. Many sports, such as basketball and baseball, essentially never have ties, so the tie field is often left at zero.
What does a .500 winning percentage mean?
A winning percentage of .500 means a team has won exactly half of its decisions, an even record with equal wins and losses. Above .500 is a winning record, and below is a losing one. The .500 mark is a common reference point for describing whether a team is performing above or below break-even.
