Win Percentage Calculator
Enter a win-loss-tie record. Ties count as half a win, the convention used in the NFL, the NHL and college sport.

Winning percentage
53.125%
(8 + 1 ÷ 2) ÷ 16 × 100
The formula
Winning percentage = (Wins + Ties ÷ 2) ÷ Games played × 100
Games played is wins plus losses plus ties. A tie counts as half a win — the convention in the NFL, the NHL and US college sport.
Worked example — 8 wins, 7 losses, 1 tie
8 + 1 ÷ 2 = 8.5
8 + 7 + 1 = 16 games
8.5 ÷ 16 = 0.53125
× 100 = 53.125%, printed as .531
Why half a win
A tie is neither a win nor a loss. Splitting it evenly means a team that ties every game finishes at exactly 50%, which is the honest answer. Counting a tie as a loss would punish a result nobody lost, and counting it as a win would reward one nobody won.
This is the league rule, not a convention this site invented. The NFL states it directly in its tie-breaking procedures: "Tie games count as one-half win and one-half loss for both clubs."
Why it is printed as .531
US sport prints winning percentage as a proportion to three decimal places, without the leading zero. A ".531 team" is a 53.1% team. Nothing differs but the notation.
Where the convention changes
- Association football mostly uses points — three for a win, one for a draw — rather than a winning percentage.
- The NHL awards a point for an overtime loss, so its standings use a points percentage that this formula does not reproduce.
- Baseball has no ties, so the tie term simply drops out.
What a winning percentage hides
It weighs every game the same. A team that beats weak opponents narrowly and loses heavily to strong ones can hold the same figure as a consistently good team. Strength of schedule and points difference answer questions this number cannot.
Common questions
- How is winning percentage calculated?
- Winning percentage = (wins + ties ÷ 2) ÷ total games × 100. A tie counts as half a win, which is the convention in the NFL, the NHL and college sport.
- Why does a tie count as half a win?
- A tie is neither a win nor a loss, so splitting it evenly keeps a team that ties every game at exactly 50%. Counting it as a loss would penalise a result nobody lost.
- Why is winning percentage often written as .625 rather than 62.5%?
- US sport prints it as a proportion to three decimal places rather than as a percentage. The two say the same thing: .625 is 62.5%.
- How many more games do I need to win to reach a target?
- Rearrange the formula: needed = (target ÷ 100 × games played − current wins) ÷ (1 − target ÷ 100). This calculator shows it for you.
