Win percentage calculator.

Divide wins by games played. A 12-5 record is 12 ÷ 17 = .706. Where a league plays ties they count as half a win, so 12-4-1 is (12 + 0.5) ÷ 17 = .735. The calculator above does both, and its NHL mode switches to points percentage.

As half a win and half a loss. The NFL adopted that in 1972; before then a tie was simply left out of the fraction, which is why some old seasons read differently in modern tables. An 8-8-1 season is .500 either way, but 9-7-1 is .559 today and would have been .563 under the old method.

The NHL standings rank teams by points, not wins: two for a win, one for an overtime or shootout loss, nothing for a regulation loss. Points percentage is points earned divided by points available, so a 50-20-12 team has 112 of a possible 164 points, or .683. Switch the mode above to get it straight from a win, loss and OT-loss record.

Anything above .500 is a winning record. Around .600 has been a playoff team in most leagues most years, .700 usually means one of the best records in the league, and .800 is rare anywhere — a 14-3 NFL season, a 66-16 NBA season, or a 130-32 baseball season that nobody has ever played.

NFL: New England went 16-0 in 2007, the only perfect 16-game regular season, and Miami went 14-0 in 1972 and finished 17-0 with the playoffs. NBA: Golden State’s 73-9 in 2015-16 (.890), ahead of Chicago’s 72-10 in 1995-96. MLB: Chicago went 116-36 in 1906 (.763); Seattle matched the 116 wins in 2001 across the longer 162-game schedule (.716). NHL: Montreal’s 60-8-12 in 1976-77 is the best points percentage (.825), while Boston’s 65 wins in 2022-23 are the most ever.

Exactly as many wins as losses. A team above .500 has a winning record and one below .500 a losing one, and “games over .500” counts wins minus losses, so 10-6 is four games over.

Baseball wrote it that way first, a fraction to three places with no leading zero, the same convention as batting average, and the other leagues’ standings copied it. The calculator shows three decimals for that reason; multiply by 100 for the everyday percentage.

Multiply the percentage by the schedule length. A .706 team is on pace for 12 wins over 17 NFL games, 58 over 82 NBA or NHL games and 114 over 162 in baseball. Read the other way, Golden State’s .890 from 2015-16 would be 15-2 in an NFL season and 144-18 across a baseball schedule.

It moves every year, so treat these as rough marks: the NBA’s tenth seed and play-in spot has often gone to teams around or just under .500; the NHL bubble sits near 95 points, about .580; ten wins (.588) has usually been enough in the NFL’s seven-team conference fields since 2020; and an MLB wild card has usually needed around 88 to 90 wins (.550). Ties in the standings are settled by head-to-head results and the other tiebreakers, never by percentage alone.

With wins in B2 and losses in C2 the formula is =B2/(B2+C2). Add ties in D2 and it becomes =(B2+0.5*D2)/(B2+C2+D2). Format the cell as a number with three decimal places; Sheets will show 0.706, and the leading zero is only the display, so drop it from the number format if you want the standings look.

Standings never do. Every league’s table is regular season only, and playoff results are kept separately. When a perfect season is quoted with the playoffs included, as Miami’s 17-0 in 1972, the record is written out in full rather than as a percentage.

Yes. The formula is the same at every level: wins over games played, ties as half where your league counts them. College football and basketball do not play ties, so those records are wins and losses only.
