In ferromagnetic semiconductors, the coupling of magnetic ordering with semiconductor character accelerates the quantum computing. The structural stability, Curie temperature (T<sub>c</sub>), spin polarization, half magnetic ferromagnetism and transport properties of ZnX<sub>2</sub>Se<sub>4</sub> (X = Ti, V, Cr) chalcogenides for spintronic and thermoelectric applications are studied here by density functional theory (DFT). The highest value of T<sub>c</sub> is perceived for ZnCr<sub>2</sub>Se<sub>4</sub>. The band structures in both spin channels confirmed half metallic ferromagnetic behavior, which is approved by integer magnetic moments (2, 3, 4) μ<sub>B</sub> of Ti, V and Cr based spinels. The HM behavior is further measured by computing crystal field energy ΔE<sub>crystal</sub>, exchange energies Δ<sub>x</sub>(<i>d</i>), Δ<sub>x</sub> (<i>pd</i>) and exchange constants (N<sub>o</sub>α and N<sub>o</sub>β). The thermoelectric properties are addressed in terms of electrical conductivity, thermal conductivity, Seebeck coefficient and power factor in within a temperature range 0-400 K. The positive Seebeck coefficient shows p-type character and the PF is highest for ZnTi2Se4 (1.2 × 10<sup>11</sup> W/mK<sup>2</sup>) among studied compounds.
