In present paper a well-behaved new model of anisotropic compact star in(3+1)-dimensional spacetime has been investigated in the background ofEinstein's general theory of relativity. The model has been developed bychoosing $g_rr$ component as Krori-Barua (KB) ansatz [Krori and Barua in J.Phys. A, Math. Gen. 8:508, 1975]. The field equations have been solved by aproper choice of the anisotropy factor which is physically reasonable and wellbehaved inside the stellar interior. Interior spacetime has been matchedsmoothly to the exterior Schwarzschild vacuum solution and it has also beendepicted graphically. Model is free from all types of singularities and is instatic equilibrium under different forces acting on the system. The stabilityof the model has been tested with the help of various conditions available inliterature. The solution is compatible with observed masses and radii of a fewcompact stars.
