If you want to know how good the last season really was for your favorite baseball or hockey team, you should definitely give this winning percentage calculator a try. All you have to do is input the number of wins, losses, and ties on the team's record, and you'll have an answer in a split second!

💡 Click on the Advanced mode button under the calculator to include tied games and to assign their value.

Win percentage formula

Calculating the winning percentage is equivalent to estimating a proportion of wins in the total number of games. If there are no tie results, you need to divide the number of wins by the total number of games (wins and losses):

winning percentage = wins / games

For example, let's assume that your favorite basketball team has played 82 games and won 48 of them. Their winning percentage is:

(48 / 82) × 100 = 58.54%

How to calculate winning percentage with ties

If, on the other hand, you want to include ties into the whole calculation, the formula gets a bit more complicated. It is usually assumed that a tie is worth the same as 1/2 of a win. In such a case, you can calculate the percentage in the following way:

winning percentage = (wins + 0.5 × ties) / games

For this equation, the number of games is the sum of win, loss, and tie results on the team's record.

To get a better understanding of this formula, let's consider the following example: a football team playing in the National Football League has played 16 games in total. They lost 4 of them and got a tie result in 5. What is their winning percentage?

  1. Determine the number of wins. If the total number of games is 16, then you can use the formula below:

    wins = games - ties - losses = 16 - 5 - 4 = 7

  2. Now, you know that the team has won 7 games during the last season. Add that number to half of the tie results:

    wins + 0.5 × ties = 7 + 0.5 × 5 = 9.5

  3. Divide the number you got by the total number of games:

    (9.5 / 16) × 100 = 59.38%

  4. 59.38% is the winning percentage of the football team you cheer for. Quite good, but still not enough to win the League!

🙋 We use percentages in almost all aspects of our life, not just sports. For example, we can also use percent to express the relative error between the observed and true values in any measurement. To learn how to do that, check our percent error calculator.

Should you bet on this team?

Even if your favorite team has a stellar track record and a winning percentage oscillating around 80%, it doesn't necessarily mean they will win the next match! Instead of calculating the win percentage, you should use our odds calculator to determine your chances when betting on them.
