The work function (W) is calculated by comparing the vacuum level (Evac) in electrostatic potential with the Fermi energy (EF),

W= Evac- EF ,

On the othe hand, the Fermi energy is given by the equation

EF= - (IP + EA)/2

where EA ia the electron affinity and IP is the ionization potential, see, the figure.

The above expressions are explained in detailed in the the attached paper:
