Implication of neutrino mass model based on $\Delta$(27) discrete flavorsymmetry, on parameters of neutrino oscillations, CP violation and effectiveneutrino masses is studied using type-I seesaw mechanism. The Standard Modelparticle content is extended by adding two additional Higgs doublets, threeright-handed neutrinos and two scalar triplets under $\Delta$(27) symmetrypredicting diagonal charged lepton mass matrix. This can generate the desireddeviation from $\mu - \tau$ symmetry. The resulting neutrino oscillationparameters are well agreed with the latest global fit oscillation data. The sumof the three absolute neutrino mass eigenvalues, $\sum\limits_{i}|m_{i}|$(i=1,2,3) is found to be consistent with that of the value given by latestPlanck cosmological data, $\sum\limits_{i}|m_{i}|<$0.12 eV. The model furtherpredicts effective neutrino masses for neutrinoless double beta decay, 4.15 meV$\leq m_{ee}\leq$ 30.6 meV, tritium beta decay, 8.4 meV $\leq m_{\beta}\leq$30.5 meV, Jarlskog invariant, $J_{CP}=\pm 0.022$ for CP violation, baryonasymmetry $Y_{B}=1.15 \times 10^{-10}$ for normal hierarchical case; and also49.5 meV $\leq m_{ee}\leq$ 51.7 meV, 49.5 meV $\leq m_{\beta}\leq$ 51.4 meV,$J_{CP}=\pm 0.022$, $Y_{B}=1.12\times 10^{-10}$ for inverted hierarchical caserespectively.
