A Look at the Different Odds Formats And How To Calculate Your Profit
Published on January 5th, 2021 7:21 pm ESTWritten By: Dave Manuel
Sportsbooks use different odds formats.
You have decimal odds, fractional odds and American odds.
All of these odds formats boil down to the same thing  they are simply a different way of presenting the information to you.
One of the most frequently asked questions that we see in the sports betting world: how do I calculate my potential winnings using each of the different odds formats?
Here is a quick and easy way of figuring out your potential profit for all three.
Decimal Odds
This is probably the easiest odds format to calculate.
Let's say that the odds for a fighter that you want to bet on look like this:
1.80
In order to calculate your potential profit, simply multiply this number by your wager, and then subtract the amount of your wager to get your profit.
So, if you bet $100 on this fighter at 1.80, your calculation would look like this:
$100 * 1.80 = $180
$180  $100 = $80
You'd be looking at a profit of $80.
If the odds were something like 3.60, it would look like this:
$100 * 3.60 = $360
$360  $100 = $260
Your potential profit in this case would be $260
American Odds
With American odds, you will see a number with either a + or  next to it.
For instance, the number might look like this:
+200
Or like this:
330
Here is how you calculate the potential profit for either one:
In the case of a number with a + in front of it (which means that the side is an underdog), the amount of the number is the amount of profit that you would earn with a bet of $100.
So, if you bet $100 on a +200 line, you would realize a potential profit of $200.
So, your potential profit would be 2x your original bet. So, if you were betting $20, your potential profit would be $40, and so on.
With a line like 330, this means that side is an underdog.
This means that you would need to wager $330 in order to have a chance of winning $100 in profit.
So, simply divide $100 by $330 and then multiply this number by your bet size in order to see how much profit you could earn.
So, if you bet $50, your potential profit would be a little over $15.
Fractional Odds
Let's say that you have a number that looks like this:
3/2
In order to figure out your potential profit, divide 3 by 2 and then multiply this number by your bet to find your potential profit.
So, in this case, we divide 3/2 to get 1.5.
We then multiply this number by our bet (let's say $100) to get $150, which represents the amount of our potential profit on this bet.

That's it!
Sportsbooks will almost always let you choose your odds format of choice, and there are plenty of calculators available online to help you figure out the odds, including this one.
