The Early Payout Calculator is a great tool to help you lock in a profit when a bookmaker offers an early payout offer and the payout has been triggered.
The most common example of an early payout offer is the 2UP offer. In this case, the early payout would be triggered if the team you have backed go two goals ahead at any point in the match.
