We present the VASPKIT, a Fortran 90 program that aims at providing a powerful and user-
friendly input/output environment toolkit to perform initial setup for calculations and post-
processing analysis to derive various material properties from the raw calculated data using the
widely-used VASP code. It mainly includes two modules. The pre-processing module is designed to
prepare and manipulate input flles such as the necessary input flles generation, symmetry analysis,
arbitrary supercell transformation, suggested band paths generation for a given crystal structure.
