How is the zoom of a 200mm lens calculated?

Zoom can be calculated by dividing the maximum focal length of a variable focal length (zoom) lens by its minimum focal length. For example a 200-400mm lens will have a modest zoom of 2x even though it’s a long lens and will allow photographing subjects further in the distance.
