What Are Betting Odds?

UK Bookmakers and Betting Exchanges use betting odds to show the likelihood of a specific outcome happening.

Betting odds are usually written down as fractions or decimals. If you are using American odds, the numbers will come with a plus (+) or minus (-) symbol.

For any given event, bookmakers can provide multiple outcomes for any one event.

Example: Let’s take betting on a football match.

You can choose to bet on the home team or the away team winning. You can also bet on a draw. Bookmakers and betting sites will provide odd values for each outcome based on the probability of them coming true.

Betting Odds Explained

How do Betting Odds Work?

The basic function of the betting odd is to give a numerical representation of the chances of an event happening.

Betting odds will also give you an idea of how much you can possibly win should you end up with a winning bet or qualifying bet.

Types of Betting Odds

There are three basic types of betting odds. They are:

  • Fractional
  • Decimal
  • American

Fractional Odds

Fractional odds are also known as British betting odds. They are called fractional because they are usually written in fractions or ratios.

Example of this odds format is 6/1 or Six to One.

Decimal Odds

This is more straightforward and easy to compute. They display the amount that you could win for every £1 wagered.

American Odds

This is also called Moneyline Odds. They have a plus (+) or minus (-) at the front of the odds. The odds with the + symbol will have a lower probability of occurring, but a higher payout.

How Much Will My Bet Win?

Below is a quick breakdown of how you can read betting odds or make sense of an odds table or the odds displayed on your betting website.

Fractional Odds

With fractional odds, the number on the left shows the potential profit should you bet the amount on the right.

Example: 8/2: Win £8 per every £2 bet staked

3/15: Win £3 per every £15 bet staked

Odds On and Odds Against

When the number on the left-hand side of the fraction is smaller than on the left, this is referred to as “Odds-On”.

When the number on the left is bigger than the number on the right, this is Odds Against.

8/2 is Odds On. 3/15 is Odds Against.

Decimal Odds

Decimal odds show how much you could potentially win by multiplying your bet stake by the odds.

Example: Odds of 3.0 on a bet of £1. Multiply the odds by the bet amount and you get the potential qualifying bet settlement of £3.00.

A bet of £6 on 4.0 odds will return £24 should that bet win. A bet of £2.5 on odds of 1.50 should return £3.75 if you are to win.

American Odds Formats

Also known as Moneyline odds, American Odds tell you the potential profit from a win. Those that have the (-) before the odd numbers are the favorites to win and those that have (+) are the underdogs.

It is calculated on multiples of 100.

Example: Team A has odds of +150.

Team B has odds of -160.

If you get a qualifying bet from a bet on Team A with +150, you win £150 per every £100 bet. If you bet £10, you win £15 in profit plus your stake.

If you bet on Team B and they win, you will win £100 per every £160 bet.

In addition to the above, other odds terms and odds formats you may encounter include:

  • Actual odds
  • Traditional odds
  • Continental odds
