In this talk I will discuss how Equivariant Localization can be used to compute observables in supergravity without the need to solve the equations of motion. We will use 6d Romans supergravity as our test case and show that the on-shell action is completely determined in terms of topological data in terms of a master formula. Our work allows us to recover known results in the literature and to make predictions for hitherto unknown solutions and their field theory duals.
