every equation you need to calculate immediate and long term deflection exists in this website:

-EI d2y/dx2=M y=deflection, x=postion along beam.
E=Young Modulus of beam material. I= 2nd moment of area of beam section.
Draw a free body diagram of your beam and work out what the moment is at any point as a function of x.
Integrate! Add constant of integration depending on boundary conditions.
Integrate again! Add constants again.
Plug in values of x (where you want to calculate deflection) to find the answer.

Go to this website. You have to have enough knowledge to know what units and material properties to use.
