A refrigeration cycle apparatus is mounted in a vehicle and has a circulation circuit through which a refrigerant circulates. The apparatus includes a refrigerant amount calculating unit and an operating state determining unit. The refrigerant amount calculating unit acquires a physical quantity and calculates an amount of the refrigerant. The operating state determining unit determines, based on traveling conditions of the vehicle, whether the vehicle is in an operating state in which the refrigerant circulating in the circulation circuit becomes a stable state. The refrigerant amount calculating unit calculates the amount of the refrigerant when the operating state determining unit determines that the vehicle is in the operation state.
