About the Winning Percentage Calculator
This winning percentage calculator turns a win-loss record into the three-decimal percentage printed in every standings table. Enter wins, losses and ties, choose how ties are treated, and it returns the winning percentage (such as .636), the same figure as a percent, and the number of games played.
Add a rival’s record to see how many games behind (GB) you are, using the standard standings formula. Add the games left in the season and a target percentage — say .600 for a playoff line or .500 for a winning season — to find how many of the remaining games you must win, and the best record you could still finish with.
It works for any sport and any level: the NFL and high school football count a tie as half a win, while many leagues and fantasy formats simply leave ties out. Coaches, fantasy managers and fans tracking a playoff race can all use it.
With the default inputs, the winning percentage is 0.636. Change any value above to recalculate instantly.
How to use the winning percentage calculator
- 1Enter your wins, losses and ties.
- 2Choose whether ties count as half a win or are ignored.
- 3Enter a rival’s or division leader’s record to see games behind.
- 4Add games remaining and a target percentage to see the wins you need.
- 5Read the winning percentage in standings format and as a percent.
Formula and method
Winning percentage is wins divided by games played. When ties count as half a win (the NFL, NCAA and most high school rules), each tie adds 0.5 to the numerator and 1 to the denominator. When ties are ignored, they are removed from both sides. The result is written to three decimals without the leading zero, so 7 wins in 11 games is .636.
Games behind is the standard standings formula: half the difference in wins plus half the difference in losses between the leader and your team. Wins needed solves (current credit + x) ÷ (games after the season) ≥ target for the smallest whole x.

Worked examples
7–4 team chasing an 8–3 leader
7 ÷ 11 = .636. The leader has one more win and one fewer loss, so you are (1 + 1) ÷ 2 = 1 game behind. A .600 finish over 17 games needs 10.2 wins, so 11 — four more out of six.
NFL record with a tie: 10–6–1
Counting the tie as half a win gives 10.5 ÷ 17 = .618. An 11–6 rival is half a game ahead, because they have one more win and the same losses.
Baseball: 88–74 season, ignore ties
88 ÷ 162 = .543. A 95–67 division winner is ((95 − 88) + (74 − 67)) ÷ 2 = 7 games ahead.
Frequently asked questions
How do you calculate winning percentage?+
Divide wins by total games played. A team that is 45–35 has played 80 games, so its winning percentage is 45 ÷ 80 = .563, or 56.3%.
How do ties affect winning percentage?+
In the NFL, NCAA and most high school sports a tie counts as half a win and half a loss, so a 10–6–1 team has (10 + 0.5) ÷ 17 = .618. Some leagues ignore ties completely.
How is games behind calculated?+
Take the difference in wins plus the difference in losses between the leader and your team, then divide by two. A 50–40 team trailing a 54–37 leader is (4 + 3) ÷ 2 = 3.5 games back.
Why is winning percentage shown without a leading zero?+
By convention standings print it like a batting average, to three decimals without the zero: .636 rather than 0.636. A perfect record is written 1.000.
Can a team be ahead in percentage but behind in games?+
Yes. When teams have played different numbers of games, games behind and winning percentage can disagree. Most leagues rank by winning percentage, with games behind as a guide.
