Pros and cons of American betting odds
As one of the most popular odds types found in online sportsbooks, American odds are commonly used by regular bettors. But for newbie punters, here are its pros and cons:
- Clear favorite indicator
- Works for all sports
- Easy to compare lines
- Confusing to read and determine values at first
What exactly are American odds?
American odds are a way sportsbooks display the “price” of a bet using a plus number or a minus number, like +150 or -200. That number does two jobs at the same time. It tells you how the sportsbook rates the chance of the outcome, and it tells you how your potential winnings are calculated for a given stake.
If you remember one idea, remember this. The sign matters. A plus number is usually attached to an underdog or a less likely outcome. A minus number is usually attached to a favorite or a more likely outcome. However, if a market has outcomes that only have plus signs, remember that the higher the value, the lesser it’s likely to happen.
So when you see American odds, you are not just looking at a random code. You are looking at the sportsbook saying, “This side is more likely,” or “This side is less likely,” and then setting the payout rules around that belief. If you understand American odds, lay betting also clicks fast because you are judging whether the price is worth taking the other side of a result.
Next, we will show you how to read the plus and minus numbers plainly.
Why do American odds have a plus or minus sign?
Plus odds show what happens on a 100 stake. When odds are positive, the number tells you the winnings you would get if your stake is 100.
Example: +150
This is read like this. If you stake 100 and win, your winnings are 150. Your total is your 100 stake plus 150 winnings, which is 250. So +150 does not mean “better” or “safe.” It means the sportsbook thinks the outcome is less likely, so the winnings on a standard 100 stake are larger.
Minus odds show what stake matches 100 winnings. When odds are negative, the number tells you how much you would need to stake to have 100 winnings.
Example: -200
This means you must stake 200 to win 100. Your total would be your 200 stake plus 100 winnings, which is 300. So -200 does not mean you are “down.” It means the sportsbook thinks the outcome is more likely, so the winnings on a standard stake are smaller.
What do the values actually mean in real life?
American odds always connect back to a simple question; “How much do I put down, and what happens if this wins?”
The plus number answers the question by fixing the stake at 100. The minus number answers the question by fixing the winnings at 100.
That is why beginners get stuck. It looks like two different systems. But it is one system with two viewpoints. If you are new, start with simple prop bets and always convert the odds into what they mean for your exact stake before you place the pick.
- Plus odds: winnings shown for a 100 stake
- Minus odds: stake shown for 100 winnings
And yes, terms and conditions always apply. Sportsbooks can adjust lines fast, limit markets, and include rules like voids, push results, settlement timing, and specific payout terms by sport and market type.
How to calculate winnings American odds
Your potential payout calculation depends if the American odds have a plus (+) or minus (-) sign indicated. Most often than not, online sportsbooks automatically calculate your potential winnings before you finalize placing a bet. This will help you easily determine your total payout if you win. Nevertheless, here are the calculations for both plus and minus odds:
How to calculate winnings for plus odds
When odds are positive, the number tells you the winnings per 100 stake. If your stake is not 100, you scale it.
Example: +150 with a stake of 40
A 100 stake would have 150 winnings. A 40 stake is less than half of 100, so the winnings are less than half of 150. You calculate it like this;
Winnings = Stake × 150 ÷ 100
Winnings = 40 × 150 ÷ 100
Winnings = 60
So if you stake 40 at +150 and win, your winnings are 60. Your total is 40 plus 60, which is 100.
How to calculate winnings for minus odds
When odds are negative, the number tells you the stake needed for 100 winnings. If your stake is smaller, your winnings are smaller.
Example: -200 with a stake of 40
At -200, a 200 stake would have 100 winnings. A 40 stake is one fifth of 200, so the winnings are one fifth of 100. You calculate it like this;
Winnings = Stake × 100 ÷ 200
Winnings = 40 × 100 ÷ 200
Winnings = 20
So if you stake 40 at -200 and win, your winnings are 20. Your total is 40 plus 20, which is 60.
Examples of American odds calculation
To give you an idea on the total payouts in comparison to the American odds and your stake, here are a few examples:
| American odds | Stake | Winnings for successful wagers | Total return |
|---|---|---|---|
| +150 | 10 | 15.00 | 25.00 |
| +150 | 40 | 60.00 | 100.00 |
| -110 | 10 | 9.09 | 19.09 |
| -200 | 40 | 20.00 | 60.00 |
| +300 | 25 | 75.00 | 100.00 |
| -400 | 25 | 6.25 | 31.25 |

Tips for reading American odds the easy way
These are the kind of tips that stop you from misreading odds when you are excited, rushed, or tilted.
If you remember nothing else, remember this. Plus means winnings shown on a 100 stake. Minus means stake shown for 100 winnings. This one tip prevents most beginner mistakes.
A lot of confusion comes from mixing them up. Your stake is what you put down. Your winnings are what you receive if your prediction is correct. Your total payout is the sum of your stake and winnings. This is also why a moneyline bet is the easiest place to practice, because it is a straight win or lose pick with a clear price attached.
A line like -350 or -500 is the sportsbook telling you the favorite is priced as very likely. That also means the winnings are usually small for the stake. Ask yourself if that is worth it before you click.
A line like +250 or +400 looks great because the winnings jump. But that number exists because the sportsbook believes the outcome is less likely. If the odds look too good to be true on a parlay bet, slow down and translate each line into stake and winnings so you understand what you are really taking on.
This is very important. Different markets settle differently. Some bets can be voided, pushed, or graded based on specific conditions. The odds tell you the price, but the rules tell you how the result is judged. Terms and conditions always apply.
Final take: Clear payout insights if you learn how to read American odds right
American odds look strange at first, but they are simply payout rules written in shorthand. Plus odds show what a 100 stake could return in winnings, while minus odds show what you would need to stake to land 100 in winnings. Once you lock that in, you start reading them the same way we have been breaking them down in this article.
What matters next is how you apply it. You want to know what the odds mean for your own stake size, and you want to understand the implied chance behind the line. Terms and conditions always apply, and odds can move, so always double check the market before you place a bet.
