I describe recent and ongoing work to evaluate the spectrum of any renormalisable theory to full two loop order, without approximations. This notably includes the Higgs, whose mass is a prediction in supersymmetric theories; in non-supersymmetric theories the calculation is used to extract the Higgs quartic coupling and test, among other things, for vacuum stability and perturbativity.
