We consider the multiple point principle (MPP) of the Standard Model (SM)with the scalar singlet Dark Matter (DM) and three heavy right-handed neutrinosat the scale where the beta function $\beta_{\lambda}$ of the effective Higgsself coupling $\lambda_{\text{eff}}$ becomes zero. We make the two-loopanalysis and find that the top quark mass $M_{t}$ and the Higgs portal coupling$\kappa$ are strongly related each other. One of the good points in this modelis that the larger $M_{t}{1mm}(\gtrsim 171\text{GeV})$ is allowed. This fact isconsistent with the recent experimental value \cite{ATLAS:2014wva}$M_{t}=173.34\pm0.76$ GeV, which corresponds to the DM mass$769{1mm}\text{GeV}\leq m_{\text{DM}}\leq 1053 {1mm}\text{GeV}$.
