We study the Hilbert polynomials of finitely generated graded algebras R, with generators not all of degree one (i.e. non-standard). Given an expression P(R,t)=a(t)/(1-tl)n for the Poincare series of R as a rational function, we study for 0 ≤ i ≤ l the graded subspaces ⊗kRkl+i(which we denote R[l;i]) of R, in particular their Poincare series and Hilbert functions. We prove, for example, that if R is Cohen-Macaulay then the Hilbert polynomials of all non-zeroR[l;i] share a common degree. Furthermore, if R is also a domain then these Hilbert polynomials have the same leading coefficient.
