In this study, we propose a rigorous procedure to derive the analytical formula that is able to describe the Stark shifted energy for arbitrary state of Hydrogen atom when it is exposed to a uniform electric field. The general formula is constructed up to second order of perturbation theory in the parabolic coordinates which are convenient to separate the variables. The applicability of the analytical formula is validated by comparison with the exactly numerical calculation. The result indicates that the formula can be applied up to 0.2 a.u. in field strength for the ground state of hydrogen atom.
