Bfttors you betyors wondered how sportsbooks make money? Many of those new to sports betting or gambling, in general, may look at sports betting from afar and consider it something that can be beaten with a bit of sports knowledge. This is called the vigorish or vig for short. One of the reasons sports betting seems so simple to a square bettor or someone who is mostly uninformed when it bettora to gambling probabilities is that they equate betting the point spread to picking outright winners. They also lack an understanding of vigorish. Read on and learn how betting sites make money and if you think you got what it takes to open your own and let us review it. In an ideal world, sportsbooks would like to have balanced action on both sides of each market.

In the Beginning …

Sports betting for a living is probably a dream job for many people. The number one reason people get into sports betting is to try and make money. You might get lucky early on in your betting career but in the long term it is extremely tough to make money from the sports betting markets. How do you bet on sports successfully? There are a few simple methods which actually do make money long term. Which are also relatively easy to learn.

The Reality

Successful bookmaking is about building margins into odds and balancing the book so no matter who wins the bookie makes a profit. Odds are not just set to reflect the probabilities of an outcome they also hoa the bookmakers own exposure. The goal of any fixed odds bookie is to ensure that each outcome is backed in the right proportion so that they make a profit whatever the outcome.

This means it is often possible to find good value odds if you are betting against the grain. In this guide we cover everything you need to know about the factors that go into pricing markets. We show you how to calculate bookmaker margins, we explain what vig and overround are and how betting sites make money. We also discuss how prices move in response to betting, what markets have higher or lower margins, how to spot overpriced odds before the bookie does as well as how to be your own bookie and use exchanges.

Ironically the last thing a bookmaker wants to do when it comes to setting odds is gamble on one outcome over. Prices howw set in a way that reduces variance and ensures profit while still roughly reflecting the real probability of an event occurring.

This is a balance of making a profit and ensuring punters are still attracted to bet on the outcome. The margin built in to a bet is referred to as the Vig s;orts Overrround which we will also discuss further.

The betting company calculate the probability of each outcome occurring and then subtract the margin. Bookmakers and odds traders calculate the real probabilities of something happening based on statistics, form, history and ultimately human opinion their own opinions, other bookies opinions and public opinion.

The more data that is available the more likely the bookmaker odds are going to reflect the real probability, if the event has never happened before or there is less data on the outcomes then bookmakers will be more cautious and their odds will be hod reflective of the real probability.

For example, football odds, on the whole, tend to be good value as there is a lot of data available. However, odds professionaal say the winner of X-factor are far less certain and so will have higher margins built in, therefore overall worse value for the punter.

The easiest way to understand odds pricing is to think of an event with just two possible outcomes. The margin therefore is Probability however is only one aspect of odds pricing. Bookies don’t actually hlw their odds based completely on the real mobey but rather on how likely they think their punters will prpfessional on each outcome, allowing them to balance their book.

See our section on how odds move in response to betting for more about. For markets where there are multiple outcomes or uneven chances we need to do a little more calculation, details can be found further down this page. The vig or overround is the process by which the bookmaker sets to balance the wagers bettore on all possible outcomes so that they will make a profit regardless of what happens.

This is in effect making a book. In practice it is rarely possible professiohal perfectly balance a book and so in reality bookmakers will tend to have liability more one way than the.

The bookmaker will change the odds lines in a run up to an event to attract bets that they have less exposure on whilst deterring more bets on lines they are over exposed on. Another way of thinking of Vig is the amount charged by a bookie for taking the bet from the punter. Technically Vigorish and Bettora are different:.

In any market where the odds are unequal or there are multiple outcomes then there is a basic and easy mathematical formula you can use to calculate a bookie margin.

For simplicity let’s say there are five outcomes with odds A-E:. To do this calculation spofts need to convert your odds to decimal. See our article on betting odds explained for more on how to do. Now let’s plug in a real world example to the equation. We have a horse race with seven runners, I’ve taken this from a race from Catterick at the time of writing, decimal odds in brackets:.

The bookie will want to have an equal proportion of bets on each line, this is the same as the proportions in the equation, so for example you would want In financial markets if there is more interest in buying the stock of a company then it will go up, if there is more interest in selling stock then it will go.

The same basic principle sportd principle is true in bookmaking. As I mentioned earlier the real probability of an event occurring is only one factor in setting odds.

The bookie starts off by making a rough prediction of the probability and then adds in their margin on top. If everyone was to now bet on just one of those outcomes then the money coming in will be skewed one way. In response to this the bookie will increase their margin on the popular line to stop people betting and will reduce their margin on the less popular line to encourage betting. You can see from this example how heavy betting on one particular outcome can move entire markets.

This commonly happens in big horse races. The process isn’t quite this risky in reality. The bookmaker doesn’t just wait to see which bets will be popular and then move the move the margins, instead they profile their customer base in attempt to predict which markets and lines will be more popular than. Now the bookmakers know there will be more betting on Manchester United, partly because they are the favourites and partly because they are more widely supported. The bookie therefore builds in a higher margin to odds on Manchester United to win over Crystal Palace.

If you bet on Palace and they win you will get a better value bet but either way the bookie doesn’t care, as long as their book is balanced they make money. No matter how hard xo individual bookie tries they can only balance their books if there is an equal proportion of bets. Betting is based on popular opinion and this means that it is simply not always possible to get the right proportions just by moving their own odds lines.

For example, a UK facing bookmaker will often be over exposed with bets on England in international tournaments. Let’s say England are playing Spain in the final, it is hard for these UK operators to attract sufficient bets to balance the book on their own without creating a huge margin on England.

If they did this people wouldn’t bet on England and they could lose money to their competitors. The bookie therefore now has a choice. Firstly, they could take the risk that England will lose and they will still make a profit. Taking risks in bookmaking is a very quick way to go out of business so instead, where possible, bookmakers will lay their liabilities with other bookmakers or through mechanisms simialr to betting exchanges. Taking the dp example if a UK facing bookie is over exposed on England then a Spanish facing bookie will be over exposed on Spain.

This means the UK bookie can lay their overall liability with the Spanish bookie and vice versa, this way they both make a small profit either way due to their margins without having to take any risks.

They do this through wholesale bookmakers how do professional sports bettors make money effectively work as a clearing house for unbalanced books. There will still always be scenarios however where all bookmakers have liabilities on the same market.

If we take the example of a strong favourite in the Grand National, now all bookmakers will be over exposed and there will be less options to lay the liabilities. In this scenario the whole industry stands to lose if the favourite wins, and this does happen quite. You read stories all the time of bookies losing millions on individual wagers, this is the nature of the industry, punters collectively can beat the bookie but it rarely happens.

In general, the bookies do not want the favourites to win. If something is favourite it is because on one hand it has a high probability of winning and on the other hand there are lots of wagers placed on it. Bookies will often how do professional sports bettors make money horrendous odds on the favourite if over exposed in the hope that people will back more outsiders to balance their book, or they hope they punters will place their bets on the favourites with another bookie who has better odds.

The converse of this is if an outsider wins the bookie will tend to win. Very rarely however the bookies get it very wrong and price an outsider at ridiculous odds. This backfired terribly for the industry and cost UK operators tens of millions.

It goes to show that bookies, for all their resources, koney price events very badly, if you are the lucky punter who happens to be on that band wagon then you can end up quids in. Simpler markets tend to have better margins because there is less variation and less chance for unexpected outcomes. The more outcomes there are in a market the higher the margin tends to be to control for variation an unbalanced books.

Goalscorercorrect score. The most popular sports and events will have the lowest margin built in. This is due to the wealth of information available coupled with the bookmakers desire to be competitive in those markets and make money. The more obscure or exotic a wager is the higher the margin. This is because there is less data so the bookie is less certain of the outcome and also because the bookie may have a harder time balancing the book. As a rule novelty and special bets tend to offer the worse value and top sports like top footballtennishorse racing.

For bettots beginner or an occasional punter sticking to lower margin markets will more likely give you better value. This doesn’t mean you shouldn’t place bets in higher margin markets. The higher margin reflects the greater uncertainty and therefore increases the chances that you might find a line that the bookie has over-priced. Jump on this before everyone else and you could make a good profit if it wins.

Higher margin vo are also more likely profedsional vary more between bookies allowing you to shop around sporhs even hedge your bets see later. There is a reason why many bookmakers tend to push offers and promotions on multiple outcome markets, this is because they have higher margins to play. This way they can offer you a deal while still making a good profit most of the time. Try not to get sucked in, a goalscorer market with a deal e. Accumulator betting attracts more bookmaker promotions than any other bet typeask yourself why?

As soon as you place an accumulator then you are in effect compounding the bookmakers margin. This is why they can afford to provide accumulator insurancefreebets, or accumulator bonuses. Let’s look at the most basic example, a double bet. You pick a tennis match between players A vs B and B vs C and let’s now say all four selections have an equal chance of winning of winning their respective matches.

By combining these selections into a double we give the bookie double the margin, 4. Of course this also applies to full cover betssuch as Lucky 15’s and Yankees, as these are just packaged multiple individual accumulators. This is also why you find so many offers for these bet types. Accumulators are great fun and give good returns when you do win but in general they are poor value bets and the more selections you have the more margin you are giving the bookie.

This again doesn’t mean you shouldn’t place them but perhaps you should only place small stake accumulators and multiples for this reason. If you believe that competition in a capitalist free market works there is no better example than modern bookmaking. Competition between betting sites forces them to run with as low a margin as they think they can get away with, this is a professionwl for a punter. A quick scan of an odds comparison site is all you need to get the best price on a major outcome.
