Our objective in this paper is to study the late-time behavior of the universe in a model resulting from a parametrization of the Hubble parameter (H) in f(Q, T) gravity. We have considered the flat Friedmann–Lemaitre–Robertson–Walker as the background metric and discussed the model in f(Q, T) gravity, where Q and T are non-metricity and the trace of the energy-momentum tensor respectively. The complicated field equations are solved in a model-independent way by using a simple parametrization of H. Some geometrical parameters and physical parameters for the obtained model are calculated and their cosmic evolution are described through some graphical representation. The physical dynamics of the model are discussed in some detail. Finally, we found the model’s validity by checking the energy conditions, kinematic behavior, and the speed of the sound for the obtained models from the parametrization of H. The interesting results of the models are compelling to the present scenario of late-time cosmic acceleration.
