In an apparatus for evaluating fuel-saving driving of a vehicle, a detecting unit detects a starting point and an end point of a deceleration area; a storage unit stores therein deceleration value information representing a deceleration value per unit time tolerated for safely decelerating from a predetermined traveling speed to a predetermined deceleration completion speed; a calculating unit calculates an actual traveling distance during a time period from detection of the starting point until detection of the end point; an acquiring/calculating unit acquires the deceleration value corresponding to the traveling speed at the detected starting point from the storage unit, and calculates a tolerance deceleration traveling distance based on the traveling speed and the deceleration value; and a judging unit judges the timing of the starting point based on a result of comparison between the actual traveling distance and the tolerance deceleration traveling distance.
