Using a semi-analytical approach based on the thin-shell approximation, we calculate the long-term evolution of supernova remnants (SNRs) while also accounting for the cosmic rays (CRs) accelerated at their blast waves. Our solution reproduces the results of state-of-the-art hydro simulations across the adiabatic and radiative stages for the gas-only case and predicts that typical CR acceleration efficiencies ($\approx 10\%$ ) can boost SNR momentum deposition by a factor of 3–5. This enhancement becomes more prominent in environments in which the gas experiences more severe radiative losses. This result may have a crucial impact on modeling the effect of supernova feedback on star formation and galaxy evolution.
