Two teams can both win ten games in a season and still finish in a different order in the standings. That is because leagues do not rank teams by wins alone. They rank them by win percentage, which compares wins with the total number of games played. As a result, it is the fairest simple way to compare teams that have not played the same number of games, and it is the number next to every record in a standings table. For the answer straight away, use the win percentage calculator at the top of this page: enter the wins, losses and any ties, choose how ties should count, and you will get the percentage instantly. This guide explains the formula, shows worked examples, and clears up the detail that causes most confusion — how ties are treated.

How to Use the Win Percentage Calculator
The win percentage calculator at the top of this page takes three numbers: wins, losses and ties. In addition, ties are optional, so leave that box at zero if your sport never ends level, as in basketball. The last choice is the tie convention. Pick “ties count as half a win” for the standard method used in most US leagues, or “ignore ties” if you want the percentage based only on games with a winner.
Press Calculate and the win percentage calculator shows the win percentage to two decimal places, the total games played, and the record in the familiar wins-losses-ties format, plus the win and loss shares of the games played. The result updates as you change the numbers, so you can test “what if” questions — for example, how much one more win would lift the percentage. Finally, enter one team at a time, make sure the figures add up to the games actually played, and leave cancelled or unplayed games out completely.
How Win Percentage Is Calculated
The formula is short:
Win percentage = wins ÷ (wins + losses) × 100
In words, you divide the number of wins by the total number of games that produced a winner, then multiply by 100 to turn the decimal into a percentage. Therefore, a team with 45 wins and 27 losses has played 72 decisive games, so its win percentage is 45 ÷ 72 = 0.625, which is 62.50%.
Standings tables often show this figure as a decimal, such as .625, instead of 62.50% — the same number written two ways, which is why this tool is also known as a winning percentage calculator. Our average calculator can help with related averages.
| Part of the formula | What it means | Example (45 wins, 27 losses) |
|---|---|---|
| Wins | Games the team won | 45 |
| Wins + losses | Total decisive games | 72 |
| Wins ÷ total | Decimal form | 0.625 |
| × 100 | Percentage form | 62.50% |
The steps, in order, are:
- First, count the team’s wins and losses.
- Then, add them together to get the total number of decisive games.
- Next, divide the wins by that total.
- Finally, multiply by 100 and round to two decimal places for the percentage.
That is all there is to it when no ties are involved. In addition, the next section covers the version of the formula you need when games can end level.
How Ties Change the Calculation
In sports where games can finish tied, a simple wins-over-games figure would treat a tie exactly like a loss. Most leagues decided that was unfair, because a tie is a better result than losing. The standard convention in most US leagues, including the NFL, NHL and MLB standings, is that a tie counts as half a win — whenever this page uses a record with ties, the figures follow that convention unless stated otherwise.
With ties counted as half a win, the formula becomes:
Win percentage = (wins + 0.5 × ties) ÷ (wins + losses + ties) × 100
Every tied game adds half a win to the top of the fraction and one full game to the bottom. The alternative is to ignore ties completely, removing them from both parts to give wins ÷ (wins + losses), as if the tied games had never been played. As a result, the two methods can give noticeably different answers for the same record, so check which convention a league or website uses before comparing percentages from different sources.
| Convention | Formula | Best used when |
|---|---|---|
| Ties count as half a win (standard) | (W + 0.5 × T) ÷ (W + L + T) × 100 | Comparing with official NFL, NHL or MLB standings |
| Ties ignored | W ÷ (W + L) × 100 | A league or table that drops tied games entirely |
| No ties possible | W ÷ (W + L) × 100 | Basketball, baseball regular games and most knockout sports |
Win Percentage Examples
Worked examples make the two conventions much easier to follow. For example, start with a record that has no ties, then look at what changes when ties enter the picture.
Example 1: 45 wins, 27 losses, no ties. Add the wins and losses: 45 + 27 = 72 games. Divide: 45 ÷ 72 = 0.625. Multiply by 100, and the win percentage is 62.50%. In decimal standings form, that is written as .625.
Example 2: a 10–5–3 record, ties counting as half a win (standard convention). The team won 10, lost 5 and tied 3, for 18 games in total. The ties add 0.5 × 3 = 1.5 wins, so the top of the fraction is 10 + 1.5 = 11.5. Divide by all 18 games: 11.5 ÷ 18 = 0.6389, which is 63.89%.
Example 3: the same 10–5–3 record, ties ignored. Now the tied games drop out completely, leaving 10 wins from 15 decisive games. That is 10 ÷ 15 = 0.6667, or 66.67% — higher than the standard figure, because removing three non-losses from the record flatters the team.
| Record (W–L–T) | Method | Calculation | Win percentage |
|---|---|---|---|
| 45–27–0 | No ties | 45 ÷ 72 × 100 | 62.50% |
| 10–5–3 | Ties = half a win (standard) | 11.5 ÷ 18 × 100 | 63.89% |
| 10–5–3 | Ties ignored | 10 ÷ 15 × 100 | 66.67% |
| 8–8–0 | No ties | 8 ÷ 16 × 100 | 50.00% |
| 0–10–0 | No ties | 0 ÷ 10 × 100 | 0.00% |
Note that equal wins and losses always give exactly 50.00%, with or without ties under the half-a-win convention. To see how a percentage moves between two values, try the percentage increase calculator or the percentage difference calculator.
Win Percentage in Different Leagues
The same formula travels across sports, but each league presents it slightly differently. College standings on sites such as NCAA.com standings list wins and losses by conference and overall, and the percentage decides seeding when teams have played a different number of games. The official NCAA team statistics pages use the same records as their starting point.
In the NFL, ties are rare but possible, and the half-a-win convention means a team at 10–5–1 ranks ahead of a team at 10–6–0, even though both won ten games. In MLB, where regular-season games cannot end in a tie, the percentage is wins divided by games played, usually shown to three decimal places. The NHL adds a points system on top, so always check whether a table is sorted by points or by percentage. For the underlying idea, Wolfram MathWorld’s page on percent explains how ratios become percentages.
| League or sport | Can games end tied? | How the percentage is normally shown |
|---|---|---|
| NFL (American football) | Yes, rarely | Decimal or %, ties = half a win |
| MLB (baseball) | No | Decimal to three places, e.g. .625 |
| NHL (ice hockey) | Standings use points | % shown alongside points |
| NBA (basketball) | No | Decimal or %, wins ÷ games |
| Soccer leagues | Yes, draws are common | Tables usually sorted by points, % used for comparison |
Common Mistakes to Avoid
Most wrong answers come from a handful of repeat errors rather than from the formula itself. The first is dividing wins by the number of games the team should have played, including fixtures that were postponed or cancelled. Only completed games belong in the calculation. The second is mixing conventions: taking a percentage from a source that counts ties as half a win and comparing it with one that ignores ties. For example, the 10–5–3 record above shows that gap can be nearly three full percentage points.
A third mistake is rounding too early: rounding 11.5 ÷ 18 to 0.64 before multiplying by 100 gives 64.00% instead of 63.89%. In addition, keep the full decimal until the final step, then round once — the win percentage calculator at the top of this page does this automatically. Finally, win percentage says nothing about strength of schedule or margin of victory, which is why leagues use tiebreakers beyond the basic record.
FAQs
How do you calculate win percentage?
Divide the wins by the total number of decisive games and multiply by 100: wins ÷ (wins + losses) × 100. A team with 45 wins and 27 losses gets 45 ÷ 72 × 100 = 62.50%. Finally, with ties, use the half-a-win convention above, or the win percentage calculator at the top of this page.
How are ties counted in win percentage?
Under the standard convention used in most US leagues, a tie counts as half a win, so the formula is (wins + 0.5 × ties) ÷ (wins + losses + ties) × 100. Some tables ignore ties instead, which gives a different result for the same record. As a result, the win percentage calculator lets you switch between the two so you can match the convention your league uses.
What is a .625 win percentage as a record?
A .625 mark means the team won 62.50% of its decisive games. One record that produces it is 45 wins and 27 losses, because 45 ÷ 72 = 0.625. In addition, shorter seasons can produce the same figure too — 10 wins and 6 losses also gives 10 ÷ 16 = 0.625.
What win percentage is a winning record?
Any percentage above 50.00% means the team won more games than it lost. Similarly, exactly 50.00% is a level record, and anything below it is a losing record.
Can win percentage be over 100%?
No. A team cannot win more games than it played, so the highest possible figure is 100.00%, reached by winning every game. Therefore, if a calculation returns more than 100%, a number has been entered in the wrong box — most often wins and games played have been swapped.
Why do standings show .625 instead of 62.50%?
It is the same value in a different format. In addition, many North American leagues print win percentage as a decimal between .000 and 1.000, while other sports and most international tables use a percentage. To convert, multiply the decimal by 100: .625 becomes 62.50%.
