The structural, electronic and optical properties of KCdF3 are investigated using the density functional theory (DFT) within the generalized gradient approximation (GGA). The calculated lattice parameters have been compared to experimental results and demonstrated to be in good agreement with them. The calculated electronic band structure of cubic KCdF3 shows that crystal has a indirect forbidden band gap with value of 2.95 eV from the high symmetry point R to gamma point in the first Brillouin Zone (BZ). The optical spectra are investigated under the scissor approximation in the photon energy range, up to 30 eV. The dielectric function and some optical constants such as energy loss functions, reflectivity, extinction, and absorption coefficients, effective number of valance electrons and refractive index are calculated.
