Win Percentage Calculator
Calculate a team’s or player’s winning percentage from wins, losses and ties (ties as half a win or ignored), games over .500, league points and the straight wins needed to reach a target.
How it works
Win % = (W + ½T) ÷ (W + L + T) — or W ÷ (W + L) when ties are ignored · games over .500 = W − L · straight wins needed = ⌈(target × games − wins) ÷ (1 − target)⌉ · points = 3W + D
Winning percentage is the share of games won, conventionally written as a three-decimal number (.625) in North American sports and as a percentage elsewhere. The NFL, the NHL standings and most US high-school associations count a tie as half a win and half a loss; other leagues simply leave ties out. Football (soccer) leagues rank by points instead — 3 for a win and 1 for a draw since FIFA’s 1995 change — so the calculator also gives points and the share of possible points earned.
Worked example
A 10-6-0 record: 10 ÷ 16 = .625, or 62.50%, four games over .500. To reach 70% the team needs 4 straight wins: (0.70 × 16 − 10) ÷ 0.30 = 4 → 14-6 = 70%. In soccer terms it would have 30 points out of 48 possible (62.50%).

Frequently asked questions
How do you calculate win percentage?
Divide wins by games played. 10 wins in 16 games = 10 ÷ 16 = 0.625 = 62.5%. If there are ties, count each as half a win: 10-5-1 = 10.5 ÷ 16 = .656.
How do ties affect winning percentage?
In the NFL and most US standings a tie counts as half a win and half a loss. Some leagues ignore ties and divide wins by wins plus losses only — choose the method above.
What does “games over .500” mean?
Wins minus losses. A 10-6 team is 4 games over .500; a 6-10 team is 4 under. .500 means winning exactly half your games.
How many wins do I need to reach a certain win percentage?
Assuming you win every remaining game, solve (wins + x) ÷ (games + x) ≥ target. From 10-6 you need 4 straight wins for 70%, and 14 for 80%.
Why write .625 instead of 62.5%?
It is a baseball and North American tradition: standings print the decimal fraction to three places and call it “six twenty-five”. It is the same number.
