An empirical fit is described to measurements of inclusive inelastic electron-deuteron cross sections in the kinematic range of four-momentum transfer 0{<=}Q{sup 2}<10 GeV{sup 2} and final state invariant mass 1.1<W<3.2 GeV. The deuteron fit relies on a fit of the ratio R{sub p} of longitudinal to transverse cross sections for the proton, and the assumption R{sub p}=R{sub n}. The underlying fit parameters describe the average cross section for a free proton and a free neutron, with a plane-wave impulse approximation used to fit to the deuteron data. Additional fit parameters are used to fill in the dip between the quasi-elastic peak and the {delta}(1232) resonance. The mean deviation of data from the fit is 3%, with less than 4% of the data points deviating from the fit by more than 10%.
