The entropy function for five-dimensional supersymmetric black rings, whichare solutions of $U(1)^{3}$ minimal supergravity, is calculated via bothon-shell and off-shell formalism. We find that at the tree level, the entropyfunction obtained from both perspectives can reproduce the Bekenstein-Hawkingentropy. We also compute the higher order corrections to the entropy arisingform five-dimensional Gauss-Bonnet term as well as supersymmetric $R^{2}$completion respectively and compare the results with previous microscopiccalculations.Comment: 17 pages, no figure, JHEP3 style, to appear in JHEP
