The effective action in general chiral superfield model with arbitrary k\"{a}hlerian potential K(Φˉ,Φ) and chiral (holomorphic) potential W(Φ) is considered. The one-loop and two-loop contributions to k\"{a}hlerian effective potential and two-loop (first non-zero) contribution to chiral effective potential are found for arbitrary form of functions K(Φˉ,Φ) and W(Φ). It is found that despite the theory is non-renormalizable in general case two-loop contribution to holomorphic effective potential is always finite.
