Any matched bettor needs a calculator that works out all your qualifying and free bets, that is why Trickybet has created the only calculator you will ever need. This calculator will tell you how much your lay bets need to be, what your qualifying loss or profit will be and of course what profit you will make when using a free bet. You can use this calculator for arb betting too, just enter the back odds from the bookmaker and the lay odds from the exchange to make a profit no matter the outcome. 

We have also added advanced features like underlay and overlay so the expert bettor can choose to place their matched bets as they see fit allowing the possibility of bigger wins while still keeping the risk to a minimum 

If you have part lays in place then that is no problem either. Just enter what you have layed and the odds and the calculator will do the rest. Telling you what you need to lay at the current odds to get the best result possible from the bet.
