A candidate for the simple empirical neutrino mass formula is found, predicting the mass proportion m₁ : m₂ : m₃ = 0 : 4 : 24 and so, the mass ratio \Delta m²₃₂/\Delta m²₂₁ = 35 not inconsistent with its experimental estimate. It involves only one free parameter and three generation-weighting factors suggested by the successful mass formula found previously for charged leptons (the simplest neutrino mass formula would predict m₁ : m₂ : m₃ = 1 : 4 : 24 and thus, \Delta m²₃₂/\Delta m²₂₁ \simeq 37). A more involved variation of this equation follows from a special seesaw neutrino model with specifically ``conspiring'' Dirac and Majorana neutrino mass matrices. In this variation m₁ : m₂ : m₃ \simeq \varepsilon ^{(\nu )} : 4 : 24, where O(\varepsilon ^{(\nu )}) = 10^-2.
