How to Use the Calculator

The margin calculator on this page is one of our esports and sports betting resources that offers you a great way to see exactly how much betting margin a bookmaker is imposing on your bets.

Our calculator is designed to be supremely easy to use and here is what you need to do:

  1. Select your preferred odds format
  2. Choose between a two-way or three-way betting event
  3. Enter the odds from your selected bookmaker
  4. Hit return and the calculator will reveal what the betting margin will be

From here, you can see how much of a margin the bookmaker is applying to the betting event, and you can use this to see whether you should stick at the betting site or try somewhere else.

How Does an Odds Margin Calculator Work?

While our margin calculator will do all of the heavy lifting for you, it’s worth having a deeper understanding of how this calculator actually works.

  1. The first thing to realise is that the calculator will initially convert the odds into a percentage that describes the implied probability. After all, if you know how to read betting odds, you’ll understand that these odds describe what kinds of returns you could make rather than the probability itself.
  2. The next thing that the calculator does is to tally up the two or three odds in the event to see exactly how much of a betting margin the bookmaker is adding. From here, you can then compare this betting margin with those featured at other betting sites to see exactly which bookmaker is giving you the greatest value for your bets.

Benefits of a Using a Bet Margin Calculator

When using a bet margin calculator, it will soon become apparent what a useful and simple tool it is. Here are the main advantages:

What is Betting Margin?

A betting margin or ‘vig’ refers to the difference between the odds set by a bookmaker and the true probability of the outcome. Such betting margins are put in place to ensure that a bookmaker can stay in business regardless of the outcome of the event.

Betting margins are best understood as a percentage. So if the bookmaker had odds that suggested that Team Spirit had a 60% chance of winning The International but you felt that the probability was closer to 50%, the 10% difference would be the betting margin. You can check out this guide that discusses the meaning of vig for a more detailed explanation.
