Although the Standard Model has been very successful in explaining the present data, it is unable to express the value of Higgs self coupling constant. It is a free parameter of the theory. Recently a Higgs like particle is reported to be discovered at CMS and ATLAS experiments at CERN LHC with a mass of about 125 GeV. The purpose of this paper is to calculate the value of Higgs self coupling constant in the Standard Model for one and two-loops Higgs potential. Considering the value of Higgs mass as 125 GeV we obtain the value of Higgs self coupling constant as 0.1373 for both one and two-loops Higgs potential. We also find that the condition for perturbative validity given by Miller is satisfied, when the Higgs mass is calculated perturbatively from the effective potential given by the massless φ^4 theory at one and two-loop level.
