Combination of Plank and BICEP2 data reported that tensor to scalar ratio r≃ 0.16 and scalar spectral index ns≃ 0.96. In this short note, it is shown that chaotic inflation with quadratic potential, which perfectly accounts for present fit to r and ns, and relatively heavy Higgs mass for fine-tuned MSSM, are both suggested to be consequences of high-scale supersymmetry (SUSY) breaking. Following this idea, we find that inflaton mass is of same order as soft mass, flatness of inflation potential doesn't need a shift symmetry, and scale of inflation energy density automatically agrees with SUSY-breaking scale. A simple realization of such high-scale SUSY breaking, in which inflaton with tri-linear superpotential serves as \it modulus, is discussed in terms of ISS-like model.
