Decoding Sports Betting Odds: A Comprehensive Guide

Understanding American Odds in Sports Betting

If you’re new to sports betting, it’s essential to understand how odds work. There are various ways in which odds are presented, including American, fractional, and decimal formats. In this article, we will focus on American odds and delve into their intricacies.

The Quirks of American Odds

American odds differ from the others in terms of their presentation and calculation. When a team is favored to win a game, the odds are typically listed with a ‘-‘ sign. This indicates the amount a bettor would need to wager in order to win $100.

On the other hand, when a team is considered the underdog, the odds are accompanied by a ‘+’ sign. This signifies the potential winnings for a bettor if they staked $100.

Understanding Favorite Odds with an Example

Let’s see American odds in action with an example. This Sunday, the Miami Dolphins are the favorites to win their game, with odds listed at -110. If you decide to place a $110 bet on the Dolphins and they emerge victorious, you would receive $100 in winnings, in addition to getting your original bet of $110 back. In total, your payout would amount to $210.

It’s important to note that negative odds indicate the amount you need to wager in order to win $100, while positive odds indicate the winnings you would receive if you bet $100.

Betting on the Underdog using American Odds

Now, let’s explore what happens when you use American odds to bet on the underdog. Suppose the Buffalo Bills are playing on that same Sunday and are considered the underdogs with odds of +240. If you decide to place a $100 bet on the Bills and they manage to secure a victory, you would receive $240 in winnings, on top of getting your original $100 bet back. Your total payout would thus be $340.

By betting on underdogs with positive odds, you have the potential to earn a higher return on your investment compared to favorites.
