A weighing system for automatically charging a casting is provided to be able to reduce the entire production cost by reducing unnecessary time that is consumed in the melting process and minimizing consumption of electric power, and a charging calculation method using the weighing system is provided. A weighing system for automatically charging a casting comprises: a body which has a setting part(12), a lighting part(16), a power switch, and a receiving switch that are formed on one side face thereof, the receiving switch receiving or intercepting data from a computer(40), and has a placement part formed on a top face thereof such that ferro-alloy to be added is placed on the placement part; a load cell(20) installed in the body and connected to the placement part; and a control part(30) which is circuit connected to the load cell to receive weighed values from the load cell, and installed in the body to display whether to increase or decrease the numerical value of the lighting part by comparing the weighed values with data values received from the computer, wherein the setting part includes a zero adjusting lever(13a) and a standard adjusting lever(13b), and a setting switch(14) for adjusting the zero point by circuit connecting the respective adjusting levers to the control part in case of adjusting the zero adjusting lever or the standard adjusting lever.
