Odds Explained
Betting with a bookmaker is rarely as simple as making a wager with one of your mates. Why? Because of a little mathematical devil known as “odds.”
If you’re a rookie bettor, you probably need to have sports betting odds explained before you place your first bet. Fail to understand them and you’ll be left sifting through a bunch of random numbers. The good news is that once you figure out how sports betting odds work, determining which team to bet on becomes much easier.
Fractional (British) Odds
Adding to the confusion for new bettors is the fact that odds can be expressed in several different ways. In the UK and Ireland, fractional odds – also known as British odds – are used.
Fractional odds aren’t the easiest to grasp, but if you remember learning fractions at school, you should be fine.
The second number in fractional odds is the denominator and it signifies the amount of the stake. The other number is the amount your stake will yield if your prediction is right. It’s crucial that you get these two numbers in the right order, otherwise you’ll find yourself betting at dramatically different odds than you expected.
Let’s say you’re placing a bet on a football match. You predict that Liverpool will win in a home game against Leeds United. The odds the sportsbook has set for that game are 2/5 (pronounced two-to-five). In this specific situation, you’d win £2 for every £5 you wager if you’re correct. So, if you were to stake £10, you’d get £14 back (your original stake of £10 plus the £4 you won). If the original stake were £50, your return would be £70: your stake of £50 plus your winnings of £20.
Decimal (European) Odds
If you’re still trying to understand how sports betting works, decimal odds are surely your best bet. This straightforward expression of odds is popular across continental Europe, as well as in Canada, New Zealand, and Australia.
To work out your potential payout, all you need to do is multiply your stake by the decimal odds. So, let’s say you bet £10 on Rafael Nadal to win Wimbledon at odds of 4.50. If Rafa wins the tournament, you’ll get a £45 payout (your stake of £10 plus £35 in winnings). This is surely the easiest way to calculate winnings.
Decimal odds are also helpful when working out the favourite in a head-to-head match. The key is to look at which of the two players or teams has the lower odds; the smaller the number, the greater the likelihood of winning and vice-versa.
Let’s stick with Rafa and look at his odds of winning a match against Stefanos Tsitsipas. If Nadal is listed at odds of 1.40 and Tsitsipas is paying 2.90, you can rest assured that Nadal is a comfortable favourite to win. Most sites allow you to choose how odds are expressed, and we’d recommend using decimal odds when just getting started.
Moneyline (American) Odds
Take a deep breath, because you’ll definitely need American betting odds explained. The first thing to look for here is a plus or minus sign. If a team’s odds are expressed as negative, then that team is the favourite. If the odds are positive, then that team is the underdog.
Let’s return to Nadal versus Tsitsipas. For the same match as above, Nadal’s American odds would be -250, which would mean you’d have to bet £250 on him winning to earn £100. Tsitsipas is the underdog at +190, which means you’d earn £190 from a £100 bet on him winning.
