We apply the Grassmann tensor renormalization group (GTRG) to the one-flavor lattice Gross-Neveu model in the presence of a chemical potential. We compute the fermion number density and its susceptibility and confirm the validity of GTRG for the finite-density system. We introduce a method analogous to the reweighting method for the Monte Carlo method and test it for some parameters.
