Are you confused by the different ways in which betting odds are presented on online sportsbooks?

American, decimal, fractional, implied odds… what’s the difference?

At WSN, we have created a simple-to-use and free betting odds calculator and converter that lets you convert American, decimal, fractional, and implied odds.

It also shows you how much you can win when you bet on specific odds, in whichever format you choose to enter them.

How to Use the Sports Betting Odds Calculator and Converter

To convert between different odds formats and calculate your payout, simply follow these 2 easy steps:

  1. Fill in the odds in any of the odds fields: American, decimal, fractional or implied
  2. Enter the amount you want to bet, i.e. your stake

That’s it!

Now you will be able to see your entered odds expressed in all other formats, as well as how much money you can win betting on them and your total payout, based on your stake.

The “To win” field will show you how much money you will make in profit, i.e. your potential winnings, while the “Payout” field will display the total amount you will receive, which includes your initial stake.

Whether you are betting on the NFL, NBA, soccer or any other sport, as well as horse racing, our payout calculator and odds converter can come in handy.

What’s the Difference Between American, Decimal, Fractional, and Implied Odds?

They all express the ratio of payoff to stake, in their own way. Check out the difference between these betting odds below.

What Are American Odds?

American, or moneyline, odds show you how much money you can win on a $100 bet. As their name suggests, they are used by American sportsbooks.

In American Odds you will either see a (+) or a (-). This means that if you bet $100 on a match with odds of +130 that when the bet wins you will receive $130.

On the flip side, the negative odd indicates that on a bet with odds of -130 that you must bet $130 in order to win $100 on a winning bet.

What Are Decimal Odds?

Decimal odds, which are mostly used in Continental Europe, present the ratio of payout to the stake, where the stake itself is also included. The favorites and underdogs of any given matchup can be identified by their numbers alone.

So the decimal odds indicate the number of winnings for every $1 wagered. So for instance, if we see the odds of something happening being 3.00 and we bet $100 on that odd then we can expect a $300 payout from this win putting us in a profit of $200.

What Are Fractional Odds?

Fractional odds, widely used in the United Kingdom, show you how much you will profit on your stake should you win. For example, if you see odds of 6/1, this means you will make a $600 profit after having staked $100.

What Are Implied Odds/Implied Probability?

Finally, implied odds are simply the implied probability of winning. As such, they are the result of the conversion of betting odds into a percentage.

Changing the odds into a percentage, or likelihood of an outcome, is an excellent way of boiling down the odds into a more easily quantifiable outcome.
