The entropy function for five-dimensional supersymmetric black rings, which are solutions of U(1)3 minimal supergravity, is calculated via both on-shell and off-shell formalism. We find that at the tree level, the entropy function obtained from both perspectives can reproduce the Bekenstein-Hawking entropy. We also compute the higher order corrections to the entropy arising form five-dimensional Gauss-Bonnet term as well as supersymmetric R2 completion respectively and compare the results with previous microscopic calculations.
