How do American betting odds work?

Most people worldwide can recognize the US dollars, which are considered the world currency. Therefore, it's not surprising that American odds are expressed in terms of money. How do they work, and how to read the moneyline odds? Let's find out.
The first thing to know is that they include only odds to win. In other words, you pick the potential winner of an event, either based on your intuition or data, such as a result from the winning percentage calculator.
Moneyline betting odds are centered around $100 that you can either win or wager, depending on how likely the victory is.

  • You're betting a favorite if the odds have a minus (-) sign in front of them. For example, -150 means you need to wager $150 for a $100 payout.
  • An underdog will have a plus (+) sign before the number. +150 would mean you could win $150 for every $100 risked.
  • For an even likelihood, you will see either +100 or -100. In both cases, the potential payout is $100.

Since converting the moneyline odds to percentage requires some effort, you may find the above association easier to remember.

How to calculate moneyline odds? Moneyline odds calculator explained

You now know how to read the moneyline odds; it's time to learn how to calculate them! The easiest way to do it is to follow the following steps:

  1. Determine the chances for and against your team's success. Let's assume they're in great shape and take 5 and 2 as an example.
  2. Divide the likelihood of losing by the victory probability to obtain the fractional odds, ff. In this case, it's 25\frac{2}{5}.
f=chances against successchances for successf = \frac{\text{chances against success}}{\text{chances for success}}
  1. Convert ff to a decimal number. In our example, f=25=0.4f = \frac{2}{5}= 0.4.
  2. Calculate the moneyline betting odds.
  • If f>1f > 1, you have an underdog, and you should use this formula:
odds=f×100.\text{odds} = f \times 100.
  • For f<1f < 1, a potential favorite, use the following equation:
odds=100f.\text{odds} = \frac{-100}{f}.

We now know how to calculate the moneyline odds from our example. Since 0.4<10.4 < 1, we can use the second equation and find the result is -250.
