A speed calculating device calculates the speed of an object around a moving body and includes: an image detection unit that captures an image of the surroundings of the moving body and detects the object from the captured image; and a speed calculation unit that calculates the speed of the object, using a moving body speed indicating the speed of the moving body and an image speed, which indicates the speed of the object and is calculated from the image, at a ratio corresponding to a distance from the moving body to the object. The speed calculation unit calculates the speed of the object using the moving body speed and the image speed such that the ratio of the moving body speed increases as the distance to the object increases and the ratio of the image speed increases as the distance to the object decreases.
