Hello
Anyone knows one betfair calculator (site, not software) to see how mutch we earn on lay by responsibility?
I can only find calculators by stake and not by responsibility
I use always 100€ responsibility, no matter the odds. Its very different lay 100€ at odd 3.0 / lay 100€ responsibility odd 3.0

Per example, if we lay 3.45 until the end with responsibility of 100€, how mutch we earn if win?


or

lay 3.45 and exit (back) at 3.90 with 100€ responsibility

The stake for 100 liability is
100/lay price - 1
In your example
100/(3.45-1) = 40.82
To calculate the profit
((lay price/back price) * -stake) + stake
In your example
((3.45/3.9) * -40.82) +40.82 = 4.71
