A route retrieval apparatus is disclosed. The route retrieval apparatus includes a storage component, a first correction component, a second correction component and a retrieval component. The storage component stores therein probe information to specify fuel consumption in each section, the probe information having been collected from probe vehicles. The first correction component corrects gradient information of each section based on the specified fuel consumption in the each section. The second correction component corrects a fuel cost of each section based on the gradient information corrected by the first correction component. The retrieval component retrieves, by using the fuel cost of the each section corrected by the second correction component, a route with a lowest total of the fuel costs from a departure point to a destination point.
