Early Payout Calculator
How it works
The Early Payout Calculator can be used to cash out for a profit when an early payout is triggered. Simply enter the exchange back odds and the calculator will tell you how much to stake to get an equal profit on any outcome.
You can find a complete walkthrough of how to use the calculator in my bet365 Early Payout (2UP) guide.
The calculator also has a dutching mode for those not using exchanges, plus a slider that gives you the option of tailoring your returns.
