An electronic device for analyzing bio-electrical impedance includes a current generator, a calibration load, a switch circuit, and a processor. The current generator generates a source current. The calibration load includes an impedance component. The switch circuit provides the source current to the calibration load or outputs the source current to an outside of the electronic device. The processor controls the switch circuit such that the source current is provided to the calibration load in response to a request for analyzing the bio-electrical impedance, and controls the switch circuit such that the source current is output to the outside of the electronic device when a voltage value of a test voltage that is provided between both ends of the calibration load according to the source current is included in a reference range.
