Definitions of Different Odds Formats

Decimals

Example : £100 x 2.2 = £220

Decimal format is probably the simplest odds format and very commonly used in many countries.You simply multiply your wager to get the final return. A decimal odds of 2 means that you will get 2 times your wager in return. So a £100 bet will turn into £200. Your profit is £100 in this case.

Often websites, apps, or tools choose to show decimal odds as the default choice because it is universally easy to understand and it's very short to write.

Fractional

Example : £100 wager on 3/1 = £400

Simply put : The first number of the left is the winnings. The second number is the wager you need to put to get that winning. So a 3/1 means that you will get £3 if you put a £1 wager. The £3 does not include your wager, so your total payout is £4.

This can get a little confusing because you have to do some mental math to compare one fractional odds to another, but alas it's the most popular way of representing odds in the UK.

American (aka Moneyline)

Example : £100 wager on +150 = £250

Positive American odds represent the money you will win if you place a £100 bet. So if the odds are +150 and you place a £100 wager, then you will get £150 as a winning. Your total payout would be £250 (£150 winning + £100 initial wager). Similarly, if you place a £100 bet on +500, that means your payout will be £600 if you win. This is relatively easy to understand.

Example : £100 wager on -300 = £133.33

Negative American odds represent how much money you need to wager in order to get a £100 winning. So -300 would mean that you need to wager £300 to get a winning of £100. This is equivalent to decimal odds of 1.33. American odds is harder to understand for some due to this flip in formula between positive and negative numbers.

How Are Odds Calculated?

Odds are calculated using a variety of data, numbers, and other factors, which means they can be impacted by various external factors such as player injuries, and the preferences of the betting market. As a result, odds can change over time, and the different factors involved in determining odds can lead to variation between bookies.

Implied Probability Definition

The implied probability of an odd is the bookmaker's predicted likelihood of a particular outcome occurring. This probability is then expressed as decimal odds. A higher implied probability means that the bookmaker believes that an event is more likely to occur, and as a result, the odds of that event will be lower.

For example, by inputting the decimal odds of 1.14 into the odds converter (7/50 fractional and -714 American), it states that there is an implied probability of 87%; this percentage represents the bookmaker's predicted likelihood of the outcome occurring.
