In search of better thermoelectric materials, we have systematicallyinvestigated the thermoelectric properties of a 122 Zintl phase compoundEuCd$_{2}$As$_{2}$ using \textit{ab-initio} density functional theory andsemi-classical Boltzmann transport theory within constant relaxation timeapproximation. Considering the ground state magnetic structure which is A-typeantiferromagnetic (A-AFM) and non-magnetic (NM) structure, we evaluated variousthermoelectric parameters such as Seebeck coefficient, electrical and thermalconductivity, power factor and figure of merit (ZT) as function temperature aswell as chemical potential. Almost all thermoelectric parameters showanisotropy between $xx$ and $zz$ directions which is stronger in case of A-AFMthan in NM. Both A-AFM and NM phase of the compound display betterthermoelectric performance when hole doped. We observed high Seebeckcoefficient and low electronic thermal conductivity in A-AFM phase along $zz$direction. The remarkably high ZT of 1.79 at 500 K in A-AFM phase and ZT$\sim$1in NM phase suggest that EuCd$_{2}$As$_{2}$ is a viable thermoelectric materialwhen p-doped.
