Win Percentage Calculator

A record only becomes a percentage once you decide what a tie is worth, and leagues disagree: the NFL counts a tie as half a win, Major League Baseball leaves ties out of the total, and a plain win rate counts only wins against every game played. This page works out all three for the record you type, side by side, each with the denominator it divided by and the fraction behind it, so you can see why 10-6-2 is 61.1%, 62.5% or 55.6% depending on who is counting. Add games that have not been played yet and it shows the record you would end up with and how far the percentage moves, in percentage points. It is arithmetic on the numbers you enter: no account, no gate, and no opinion about a game that has not happened.

Ties to add
Leagues count a tie differently. The NFL counts a tie as half a win, which makes a 10-6-2 record 61.1%. Major League Baseball divides wins by wins plus losses, so a tie sits outside the total and the same record reads 62.5%. A plain win rate counts only wins against every game played, and reads 55.6%. All three are on the page because no single one of them is right for every league.

Common questions

How do you calculate win percentage?
Divide the wins by the games that count, and the tie rule decides which games those are. With ties left out it is wins over wins plus losses, so 10-6-2 is 10 divided by 16, or 62.5%. Counting a tie as half a win adds half to the top and keeps the tie in the bottom: (10 + 2 divided by 2) divided by 18, or 61.1%. Counting a tie as nothing keeps the tie in the bottom only: 10 divided by 18, or 55.6%. The page prints the substituted division it used, the fraction, and the total it divided by, so the number can be checked rather than trusted.
How should a tie count?
It depends on the league, which is why all three are shown at once rather than one being chosen for you. The NFL counts a tie as half a win. Major League Baseball divides wins by wins plus losses, so a tie sits outside the total. A plain win rate, common where a draw is simply a result that is not a win, counts only wins against every game played. Pick the one your standings use with the three buttons, and the other two stay on the page for comparison.
What is the difference between 62.5% and .625?
They are the same number written two ways. Standings print a win percentage as a three-decimal figure with no leading zero, so .625 is read as six twenty-five, and a perfect record reads 1.000. Both forms appear here: the percentage in the large figure and in each row, the three-decimal form beside it. A percentage that does not terminate is shown to one decimal place and says so, with the exact fraction printed next to it, so 1-2 reads 33.3% with 1 / 3 beside it.
What will my record be if I win the next two games?
Put 2 in the wins to add box under Games still to play. A 10-6 record becomes 12-6, the percentage goes from 62.5% to 66.7%, and the change is shown as +4.2 points, meaning percentage points rather than a percentage of a percentage. Losses and ties to add work the same way and follow whichever tie rule is selected. Empty those boxes and the projection disappears, leaving the record as it stands. This is arithmetic on a record you supply, not a prediction about any game.
Does a 0-0 record have a win percentage?
No, and the page says so rather than printing 0% or NaN. With no games played there is nothing to divide by, so it asks for at least one game. The same happens in one other case: if every game entered is a tie and you have chosen to leave ties out of the total, that rule has nothing left to divide by, and the message tells you to count a tie as half a win or as nothing to get a percentage. The other two rules still show a figure for that record.
Do my numbers leave this browser?
No. The counts are read and divided in the page itself, with no upload, no account and no sign-up. The last record you typed is kept in this browser so the page opens where you left it, and the Start over button at the top of the page forgets it. The site counts that this tool was opened, the name of the tool and nothing else: not your wins, losses, ties or any figure on the page.

Exact arithmetic on the record you enter, and the tie rule is yours to choose because leagues differ: a tie can count as half a win, as nothing, or be left out of the total entirely. Each choice is shown with the denominator it uses.
