The method for calculating the fuel injection amount of a fuel vapor dual purge system may include the steps of calculating, by a controller, volumetric efficiency of a combustion chamber, determining, by the controller, a fuel vapor detection delay time at which the fuel vapor is detected in a surge tank according to the calculated volumetric efficiency of a combustion chamber, calculating, by the controller, a time at which the fuel vapor is injected into the combustion chamber based on the determined fuel vapor detection delay time, and calculating, by the controller, a fuel vapor total injection amount at the time at which the fuel vapor is injected into the combustion chamber. The method may be performed in a turbocharger operation section.
