# Odds Formats in sports betting explained

Understanding the odds of a game is essential for the sports trading world, so you know how much you could expect from each bet. When displaying odds, there are generally three different ways bookmakers choose to do so. These are:

## DECIMAL ODDS

Widely used in various parts of the world, decimal odds is arguably the easiest odds format to comprehend.

They reflect the inverse of the probability of its corresponding outcome.

Decimal odds quote the ratio of the potential payout to the initial stake. In other words, if you place a \$10 bet at odds of 1.9, a winning bet returns \$19.

Remember that the stake is included in the return, making the remaining \$9 your profit.

## MONEYLINE / american odds

Also called American odds, Moneyline odds can either be quoted with a positive or negative sign.

To illutrate the difference, consider the following example:

New York Yankees -145
Toronto Blue Jays +125

When positive, the number indicates the potential profits on a \$100 bet.

This is used when the outcome is considered less likely to happen than not, and suggests that you are betting on an underdog.

When negative, the number indicates the amount that must be wagered to potentionally win \$100 in profits.

This is used when the outcome is more likely to happen than not, making a negative sign the hallmark of a favourite.

## FRACTIONAL odds

Favoured in the United Kingdom and Ireland, fractional odds quote the potential return relative to the stake.

For example, a won £100 bet at odds of 2/1 would imply that the bettor made £200 in profits, whereas the same bet at 1/2 imply profits of £50.

## HOW DO THESE THREE ODDS TYPES RELATE TO EACH OTHER?

It’s easier to see for yourself:
