Both heads and tails will have -110 odds, meaning you have to bet $110 to win $100. If two people bet $100 on opposite sides, the bookmaker will pay the winner using $100 of the $110 that was bet on tails, and pocket the remaining $10 for itself. That $10 made on a wager of $110 means the vig is 9.09%. Working out an implied probability percentage from fractional odds is simple. You just divide the stake by the combined sum of the two numbers which make up the fractional odds. In the case of 2/1 the equation looks like this: 1 / (2+1) = 0.33 or 33%. For odds of 8/13 this is the equation: 13 / (8+13) = 0.62 or 62%. When you bet for the underdog, it is called betting 'against the odds.' For example, if odds are 3/1 for the Cowboys this Sunday, then it is three times more likely that they will lose than win. Odds of 3-1 indicate that if you bet $100, you will win $400, the original amount of your bet plus the profit.

There are two ways odds – or prices – are displayed at racecourses in Britain: the traditional fractional system or the more recently introduced decimal system.

The odds will change heavily if the team makes a late swap. Vegas Odds & Betting Lines. Betting is popular across the US, with many forms taking differing priorities. With Nevada seen as the hub of betting in the country, gamblers flock to Las Vegas to experience the thrills of betting, both on casino games and sporting events.

Fractional odds:

These are usually displayed in this format: 4/1.

In spoken form this is “Four-to-one” and sometimes this can be written as: 4-1.

Odds are just maths. To illustrate some examples, let’s call each number a unit. So:

4/1: For every 1 unit you stake, you will receive 4 units if you win (plus your stake).
7/2: For every 2 units you stake, you will receive 7 units if you win (plus your stake).
9/4: For every 4 units you stake, you will receive 9 units if you win (plus your stake).

If you see fractional odds the other way round – such as 1/4 – this is called odds-on and means the horse in question is a hot favourite to win the race.

In spoken form this is “Four-to-one on”.

1/4: For every 4 units you stake, you will receive 1 unit if you win (plus your stake).
1/2: For every 2 units you stake, you will receive 1 unit if you win (plus your stake).

Sometimes you will see Evens or EVS displayed. This is the equivalent of a 1/1 fraction. Again it means the horse in question is expected to win the race.

EVS: For every 1 unit you stake, you will receive 1 unit if you win (plus your stake).

Decimal odds:

These are usually displayed in this format: 5.00.

5.00: Simply multiply this number by your stake to calculate your total potential returns if you are placing a win bet. Unlike fractional odds, your stake is already factored into this price i.e. this is the equivalent of 4/1 plus the 1 unit you stake.

Favourites:

How To Calculate Odds Payout

Each race has a favourite. This is the horse most likely to win, which is reflected in having the shortest price displayed with betting operators.

You will see an F alongside the horse’s odds when they are the favourite. If more than one horse has the same odds of winning according to the betting market, this will be displayed as JF, meaning joint-favourite.

What about odds when betting each-way?

Explain Betting Odds Football

Racecourse bookmakers operating at Jockey Club Racecourses must meet (or exceed in the customer’s favour) a standard set of terms if you decide to place an each-way bet.

Explain Betting Odds Ratio

You will appreciate it is not affordable for bookmakers to pay out on all four places in a four runner race (!) so these agreed terms concerning place part of your each-way bet have to vary dependent on the number of runners and type of race. These are:

Understanding Betting Odds
