Abstract: A method for controlling an induction heating apparatus of one embodiment comprises starting to heat a container, obtaining an inductance value of the container, calculating an overheating determination index based on the inductance value, comparing the overheating determination index with a predetermined first reference value, and determining whether to stop heating the container based on results of the comparison between the overheating determination index and the first reference value.
