Understanding Matched Betting

Matched betting is a popular and effective method for making a guaranteed profit from promotions and free bets offered by bookmakers licensed by the UK Gambling Commission. The core principle is to cover all possible outcomes of an event by placing two separate bets: a 'back' bet with a bookmaker (betting that an outcome will happen) and a 'lay' bet on a betting exchange (betting that the same outcome will not happen). By doing this, you cancel out the risk and can lock in a profit from the free bet offer.

The process usually involves two stages. First, you place a 'qualifying bet' to unlock the bookmaker's free bet offer. This usually results in a very small, calculated loss. Once you have the free bet, you repeat the process, but this time you use the free bet stake. Because you are not using your own money for the back bet, the calculations change, and you are able to guarantee a profit regardless of the outcome. Our calculator at Calculator Site is designed to handle both of these scenarios, making the process straightforward.
