American Odds Explained for 2026: A Comprehensive Guide to Understanding And Using the Odds Format
As you know by now, betting is figuring out how likely something is to happen. However, that can be a bit challenging if you’re not sure how to read the odds or understand what they mean for your potential winnings.
The good thing is learning American odds makes all this easier. That’s because instead of multiplying and calculating what your return could be, American odds tell you the story right away. But that’s only the tip of the iceberg. In this article, we’ll talk more about American odds and why they’re so popular with bettors.
American odds explained
Before we talk about why American odds are so popular, let’s first get down to the basics because it tends to get confusing, especially if you’ve been used to decimal odds for prop bets while betting.
Unlike decimal odds where you have to multiply your bet by the number shown, American odds focus on how much you need to risk or how much you can win. They are usually written with a plus (+) or minus (-) sign, and that small detail can make it easier for you to understand the chances and potential payouts at a glance.
A plus sign means that the selection is an underdog. So, if you place a $100 bet, the number next to the plus sign shows how much profit you could make if your selection wins. To explain it further, we’ll look at this example.
| Teams | Odds |
|---|---|
| Washington Wizards ML | +450 |
| Milwaukee Bucks ML | -300 |
In this example, the Wizards are the underdog at +450. That means a $100 moneyline bet on the Wizards would earn you $450 in profit if they win plus, your original $100 bet back. So, in this scenario, your total return would be $550.
On the other hand, a minus sign means your selection is the favorite. So, this means you have to bet more to win a smaller profit, because the outcome is more likely to happen. Using the example above where the Bucks are -300 favorite, you would need to bet $300 to make a $100 profit if they win. In this case, your potential total return would be $400 which includes your original $300 stake plus the $100 profit.
Why are American odds so popular?
Now that you understand how the plus and minus signs work, you might be wondering why American odds are so popular. Besides the reasons we’ve mentioned above, here are a few more factors that make American odds a favorite among bettors:
It helps manage your bankroll
Bankroll management is something that gets thrown around a lot of times in betting circles. But the truth is only a few practice it and that’s because most do not have systems in place to make it possible.
One thing we love about using American odds is that they make bankroll management much simpler since you can quickly see how much you stand to win from the risk you are taking. This way, you can set limits and avoid overcommitting on each bet which tends to happen sometimes especially when emotions are running high.
It helps understand probabilities
As we’ve mentioned in the intro, betting is all about knowing the probability of something happening – regardless of lay betting or back betting. American odds makes this much easier because you can convert them into implied probabilities by simply using a formula based on whether the odds are positive or negative.
For positive odds, the formula is dividing 100 by the odds plus 100. So, using the example above with the Wizards at +450, you divide 100 by 550, which gives you an implied probability of 18.2%. This means that the sportsbook believes the Wizards will win a little over 18 times out of 100 versus the Bucks.
By understanding these probabilities, you can compare what the sportsbook thinks will happen versus what you believe will happen. So, if you think that the underdog has a better chance than the implied probability suggests, that’s when a bet may offer value.
It makes odds shopping easier
If you’ve been betting for quite a while, then you know as we do how important it is to shop for lines. That’s because small differences can add up over time and significantly affect your results in the long run. The thing with American odds is you can easily find which sportsbook is offering the best value at a glance.
For example, seeing +449 at one book on the Wizards and +450 at another immediately tells you where the better payout is without doing extra math. While this might not seem like a lot, these tiny differences can add up quickly especially if you are placing multiple bets or following a long-term betting strategy. When you take the better odds consistently, you are giving yourself a long-term advantage which is pretty nowadays considering how quickly lines can move.
It simplifies parlay betting
Another reason why American odds are so popular among bettors is that it simplifies parlay betting. If you’ve placed a parlay bet or two using decimal odds, then you know how quickly the math can get confusing when combining multiple selections.
By using American odds, you can see right away how much you can win on each leg of your parlay bet. This way, you can compare different combinations and see whether the potential payout is worth the risk you are taking. Moreover, it also helps you avoid overextending your bankroll on a parlay bet which happens more often than you’d expect especially when the idea of chasing big payouts clouds your judgment.
It is used across North American sports
The first time we learned about American odds, it felt like we just unlocked some secret code. That’s because American odds are the standards across major North American sports, including the NBA, NFL, NHL, and MLB. When you can understand them, you can quickly find the selections that offer more value which is important considering how fast lines move in all major North American sports. This means no more multiplying decimals or figuring out complicated fractions which means that you can focus on your betting strategy instead of getting caught up in complicated math.
