Below you will find our free to use Matched Betting Calculator. Simply select the bet type you are looking to make and the fill in the back stake & odds at the bookmaker & the lay odds & commission on the betting exchange. Your lay stake, liability at the betting exchange will be returned to you along with the profit/loss on that selection

When cashing out a free bet it is important to know whether the free bet stake is returned or not by the bookmaker in question so always read the Terms & Conditions on the site you are using or if you need any guidence please just drop us a line at and we will be glad to help.

One thing to remember is that the free bet stake is not returned you are looking for a bet at odds of 3.5 or above to make around 65% of your free bet back as profit. Of course the higher the odds the more money will be tied up for the duration of the bet as the liability at the exchange will be more, but this still of course all risk free.

As a rough guide, with equal back and lay odds, the % return for a non returned stake offer will be approximately:

  • 50% at odds of 2
  • 60% at odds of 2.63
  • 70% at odds of 3.7
  • 80% at odds of 6
  • 90% at odds of 20
  • 94% at odds of 100

Try entering different permutations of BACK and LAY odds at first to see what effect the difference in odds have on the overall liability and more importantly your profits so you can find a level of liability to profit ration that you are happy with.

We also have an Advanced Mode for the calculator too where you can select the amount you wish to underlay / overlay the bet by in order to weight it towards a particular outcome.
