PROBLEM TO BE SOLVED: To provide a power consumption prediction device, a navigation device using the same, and a power consumption prediction method capable of improving accuracy in predicting the power consumption of an air conditioner.SOLUTION: A power consumption prediction device includes: an actual result recording unit 15 for allowing an actual result data storage unit 16 to store meteorological information, an air conditioner actuation time, and a vehicle travel time by association during the traveling of a vehicle; a correction value calculation unit 17 for calculating the ratio of the actuation time to the travel time for each item of meteorological information as a correction value; and a power consumption prediction unit 19 for predicting the power consumption of an air conditioner with the use of the correction value corresponding to the meteorological information acquired at the time of prediction. A correction value corresponding to a meteorological condition at the time of prediction is acquired based on the actual values of an actuation time and a travel time stored in the actual result data storage unit 16 during the past traveling of the vehicle, and then the power consumption is predicted with the use of the correction value. Thus, the power consumption is accurately predicted in accordance with the actual use state of the air conditioner by a user using the vehicle.
