How Betting Odds are calculated

Understanding the underlying mechanics behind betting odds is key for any punter who aims to master the game and get an edge over the bookmakers. Of course, it’s extremely difficult to beat the bookies because, in every casino, the house always wins. Still, with an understanding of how odds are calculated, you’re in a better position to have a sustainable gambling experience and not just always lose money to gaming platforms.

While sites like betting.net can do so much as offer betting tips or provide info about promotional bonuses on different bookies, that’s not enough to give any punter an edge because the bookies deliver odds in a way that isn’t in favour of the gambler. We’ll consider how the bookmakers generate their odds; perhaps you get insights on how to manoeuvre your way around their rigged system.

Data Analysis

The bookies employ data analysts to investigate fixtures and compile odds of future events by evaluating their gathered data. Although most of the processes are now handled by AI and algorithms following the advancement of technology, there is still a reasonable amount of human involvement, especially for high-profile fixtures – the ElClásico between Real Madrid and Barcelona, for example.

These data analysts have the best tools to work with – from algorithms to statistical data and even mirroring programs to analyse the odds offered by other bookmakers, so they remain competitive and at the same time not become a tool for experienced punters who are looking for betting arbitrage opportunities.

Cash Flow Projections

Next on their list of activities is to make cash projections, which involves an analysis of potential cash flow in a specific market. The analysts use algorithms that also consider previous cash flows on the same market but different fixtures to improve the accuracy of the evaluated number.

The bookmakers must evaluate cash flow to keep an individual balance sheet of each outcome in a market on a particular fixture. The balance sheet helps keep things clean and ensures they don’t lose money when customers place their bets. More so, it helps them better readjust the odds to the relevant values before, even in cases of live match bets.

Addition of Margin

Now, this is where the bookmakers do the manipulation to profit in their pockets. Before the odds are posted on bookmarker sites, they tweak them, adding “Margin” or “Juice.” Margin or Juice is the extra value added to odds that makes them exceed the normal value they should be.

This ‘profit margin’ ensures that the bookies always win regardless of how a punter tries to place multiple bets. After evaluating the true probability of an outcome, they insert the profit margin so that even if a punter wins, they’re always paid less than what the actual probabilities of outcome represent. Profit margins are artificially generated, just like how people buy watch time, likes and subscribers on YouTube channels to make the channel convert more viewers/customers.

For example, in a final ElClásico fixture;

• Barcelona: To win has odds of 2.20 (which means the team has a 45.45% chance of winning)
• Real Madrid: To win has odds of 1.50 (which means the team has a 66.66% chance of winning)

Ordinarily, the probability of at least one of them happening should be 1 (100%). However, the offered odds are 45.45% and 66.66%, which totals to give 112.11% – an abnormal value for percentage.  The extra 12.11% is the profit margin. This means even if you bet on both teams to win, you’re risking 12.11% to make 100% in return. As such, to place the bet at $121.11, you only get paid $100 in any winning case.

Meanwhile, dubious practices like match-fixing are also part of bookmakers’ numerous activities to ensure they get an edge over you. However, as most of these processes are automated, there are sometimes slipups from the bookmakers, which give them high odds that might be in favour of the punter – although this is very rare with top-level casino platforms.
