An exhaust gas control method of an engine may include calculating a target mass flux of EGR gas by using air mass entering into a cylinder and target air mass supplied into the engine, calculating a target effective flow area (EFA) of the EGR valve by using the target mass flux of the EGR gas and front/rear condition of the EGR valve, and calculating a valve opening rate of the EGR valve by using a predetermined curve fitting formula and the target effective flow area (EFA).
