The maths

How to calculate win percentage

With no ties it is simply wins ÷ games played. A 12-4 season is 12 ÷ 16 = 0.750, written .750 in a standings table and read as 75%. Both forms mean the same thing; the decimal just sorts cleanly in a narrow column, which is why baseball adopted it and everyone else copied.

Ties are where it gets inconsistent. The common convention treats a tie as half a win: (wins + 0.5 × ties) ÷ total games. An 8-6-2 record is (8 + 1) ÷ 16 = .563. Some competitions instead drop ties from the calculation entirely and divide wins by wins plus losses, which for 8-6-2 gives .571 — a different number for the same record. Neither is wrong; they answer slightly different questions. The checkbox above switches between them so you can match whichever your league uses.

A record above .500 is a winning one, below it a losing one, and exactly .500 means half the games went each way — 41-41 across an 82-game NBA season. Watch out for sports that award points rather than counting wins directly: hockey standings run on a points system where an overtime loss still earns a point, so a team's points percentage and its win percentage are not the same figure.

By sport

Win percentage by sport

Which convention you want depends on whether your sport has ties at all. The NFL is the well-known case where they still happen, and its standings count a tie as half a win — a 9-7-1 season is (9 + 0.5) ÷ 17 = .559. Leave the checkbox on its default and you will match the published figure.

Baseball and basketball effectively never end level, so the tie box stays at zero and both conventions collapse to the same answer: wins ÷ wins plus losses. That is why an MLB or NBA standings column only ever shows two numbers.

Football (soccer) is the one to be careful with. League tables there are ranked by points — three for a win, one for a draw — not by win percentage, so a table position will not match anything this calculator produces. The percentage is still useful for comparing form, it just is not what decides the league.

Outside sport, win rate in poker, esports or trading usually means the same arithmetic with pushes and voids thrown out — which is the ties-excluded setting. Same formula, different name.

Worked examples

The same record, both ways

Ties are the only place the two methods disagree, and the gap widens the more of them you have. A few records run through both:

RecordHalf-winTies excluded
12-4.750.750 — no ties, both agree
10-5-3.639.667
8-6-2.563.571
9-7-1.559.563 — a typical NFL season
0-0-6.500undefined — nothing decided

That last row is not a trick. Six draws and nothing else gives you exactly half under the first method and no answer at all under the second, because there is nothing to divide by. The calculator says so rather than showing a zero.

Spreadsheets

The formula in Excel or Google Sheets

If you are keeping a season in a spreadsheet, with wins in B2, losses in C2 and ties in D2, it is one formula either way.

Ties as half a win
=(B2+0.5*D2)/(B2+C2+D2)

Ties excluded
=B2/(B2+C2)

To display it the way a standings table does, format the cell as Number with a custom format of .000 — that gives you .750 rather than 0.75. Wrap the second formula in IFERROR if a team might have played nothing but draws, or the division by zero will show through.

FAQ

How do you calculate win percentage?+

Divide wins by games played. A 12-4 record is 12 ÷ 16 = 0.750, or 75%. If there are ties, the usual convention counts each tie as half a win, so the formula becomes (wins + 0.5 × ties) ÷ total games.

How do ties affect win percentage?+

Most leagues count a tie as half a win. An 8-6-2 record works out as (8 + 1) ÷ 16 = 0.563. Some competitions instead ignore ties entirely and divide wins by wins plus losses, which gives a different number, so it is worth knowing which convention your league uses. This calculator does both.

What does a .500 record mean?+

It means exactly half the games were won — 41-41 in an 82-game NBA season, for example. Above .500 is a winning record, below it a losing one. The .XXX form is just the win percentage written as a decimal with the leading zero dropped.

Why is win percentage written like .750 instead of 75%?+

It is a baseball convention that spread to other sports. The two say the same thing: .750 and 75% are the same number. Standings tables use the decimal because it sorts cleanly and fits in a narrow column. This calculator shows both.

Is the win percentage calculator free?+

Yes — free, no sign-up, and it runs entirely in your browser. Nothing you type is sent anywhere.

How do I calculate win percentage in Excel?+

With wins in B2, losses in C2 and ties in D2, use =(B2+0.5*D2)/(B2+C2+D2) to count a tie as half a win, or =B2/(B2+C2) to leave ties out. Format the cell with a custom number format of .000 if you want it to read .750 the way a standings table does. Wrap it in IFERROR if a row might have no decided games.

How do you calculate win percentage in baseball?+

Wins divided by wins plus losses. Baseball games are played to a result, so ties almost never enter into it and the tie setting makes no difference. The figure is written as a three-decimal number with the leading zero dropped — 92-70 becomes .568.

Does the NFL count a tie as half a win?+

Yes. NFL winning percentage adds half a win for each tie and divides by every game played, so a 9-7-1 season is (9 + 0.5) ÷ 17 = .559. That is the default setting here, so the number matches the published standings without changing anything.

Is win rate the same as win percentage?+

The arithmetic is the same; the conventions differ. Win rate in poker, esports or trading normally throws out pushes, draws and voided results and divides wins by decided attempts, which is the ties-excluded setting. Tick that box and the calculator gives you a win rate.
