What does winning percentage mean?
Winning percentage is the share of games a team has won, written as a three-digit decimal: a team that wins 6 of every 10 games is a .600 team. It's the number standings are sorted by in most leagues, because it compares teams fairly even when they haven't played the same number of games.
The reference point is .500 — exactly as many wins as losses. "Above .500" means a winning record, "below .500" a losing one, and whole seasons are told as the story of a team fighting to get back to .500. Everything else about the stat is just arithmetic on the win–loss record.
How to calculate win percentage
Without ties, divide wins by games played:
Win percentage = W ÷ (W + L)
A team with 90 wins and 60 losses has played 150 games:
90 ÷ (90 + 60) = 90 ÷ 150 = .600
How to calculate winning percentage with ties
Where ties are possible, each tie counts as half a win:
Win percentage = (W + 0.5 × T) ÷ (W + L + T)
An NFL team at 10–6–1 works out to (10 + 0.5) ÷ 17 = .618. This half-win rule is how the NFL has ranked teams since 1972 — before that, ties were simply left out of the calculation.
Why is it written .667 and not 66.7%?
Sports notation drops the leading zero and keeps three decimal places: 0.667 becomes .667, read aloud as "six sixty-seven". It's a convention from newspaper standings, where column space was precious. The calculator above shows both forms, so you can quote whichever your league uses.
Ties in MLB, NFL and NHL: three different answers
Every league divides wins by games — they differ only in what happens when a game doesn't produce a winner. Switch leagues with the presets in the calculator above.
| League | Season | Ties? | How the math handles it |
|---|---|---|---|
| MLB | 162 | No | Games play to a winner, so PCT is simply W ÷ (W + L). Historical ties were replayed or excluded, never counted. |
| NBA | 82 | No | Overtime continues until someone wins. Straight W ÷ (W + L). |
| NFL | 17 | Yes | Regular-season games can end tied after one overtime. Each tie counts as half a win: (W + 0.5 × T) ÷ (W + L + T). |
| NHL | 82 | No, since 2005–06 | Every game produces a winner, but an overtime or shootout loss still earns 1 point. Standings use points percentage: PTS ÷ (GP × 2). |
What counts as a good win percentage?
Context is everything — a percentage that wins one league is mid-table in another:
- MLB: .600 over a full season is elite. The 116-win 2001 Mariners finished at .716, the best record of the modern era.
- NBA: .700+ marks a genuine title contender; the 73–9 Warriors of 2015–16 peaked at .890.
- NFL: with only 17 games, .750 (a 13-win season, near enough) usually wins the division. The 1972 Dolphins' 14–0 remains the only perfect 1.000 regular season.
- NHL: a points percentage above .650 is typically a top seed.
One caveat: small samples lie. A 3–1 start is .750 but says very little — winning percentage stabilises as the games pile up, which is why early-season standings look so strange.

Win-loss record terms, explained
| Term | Full Name | What It Means |
|---|---|---|
| PCT | Winning Percentage | Wins divided by games played, written as a three-digit decimal like .667. With ties: (W + 0.5 × T) ÷ (W + L + T). |
| W–L | Win–Loss Record | Results written as wins–losses, or wins–losses–ties where ties exist, e.g. 10–6–1. |
| .500 | Break-Even Record | Exactly as many wins as losses. Above .500 is a winning record, below it a losing one. |
| T | Tie | A game with no winner. Counts as half a win in NFL percentage; doesn't exist in modern MLB or the NBA. |
| P% | Points Percentage | The NHL's standings measure: points earned ÷ points available, PTS ÷ (GP × 2). A win is 2 points, an OT/SO loss is 1. |
| GB | Games Behind | How far a team trails the leader: ((leader W − trailing W) + (trailing L − leader L)) ÷ 2. |
Frequently asked questions
Divide wins by total games played: winning percentage = W ÷ (W + L). A team with 90 wins and 60 losses has played 150 games, and 90 ÷ 150 = .600. In sports notation the result is written as a three-digit decimal — .600 rather than 60%. If your league has ties, count each tie as half a win (see the next question).
Count each tie as half a win and divide by all games played: (W + 0.5 × T) ÷ (W + L + T). This is how the NFL has computed winning percentage since 1972. An NFL team at 10–6–1 has (10 + 0.5) ÷ 17 = .618. The calculator above handles this automatically — enter ties and it applies the half-win rule.
A .500 team has won exactly as many games as it has lost — a 75–75 record is .500, the break-even mark. Teams "above .500" have a winning record and teams "below .500" a losing one. The phrase comes from the three-digit notation: 75 ÷ 150 = 0.500, written .500.
Sports standings traditionally print winning percentage as a bare three-digit decimal with the leading zero dropped — .667, not 0.667 or 66.7%. It is read aloud as "six sixty-seven". The maths is identical either way; the calculator above shows both forms so you can use whichever your league prefers.
Effectively no. Modern MLB games are played to a winner, so ties do not occur in the standings — winning percentage is simply wins divided by decisions, W ÷ (W + L). Historical ties (from suspended games in earlier eras) were replayed or excluded from the calculation rather than counted as half-wins.
The NHL ranks teams by points percentage rather than raw winning percentage: standings points earned divided by points available, P% = PTS ÷ (GP × 2). A win is worth 2 points and an overtime or shootout loss 1 point, so a team at 40–30–12 has (40 × 2 + 12) = 92 points from 82 games, and 92 ÷ 164 = .561. Pick the NHL preset above and enter OT/SO losses in the third field.
It depends on the league. In MLB anything above .600 over a season is elite — the 116-win 2001 Mariners finished at .716. In the NBA, .700+ marks a title contender and the 73–9 Warriors peaked at .890. In the NFL's short season, .750 usually wins a division, and the 1972 Dolphins' 14–0 season is the only perfect 1.000. Sustained play above .500 is a winning team in any league.
