The most important industry in Olvan is agriculture, especially the cultivation of grains and potatoes, as well as the raising of pigs. The village of Olvan has two small groceries and two cafés, and its inhabitants are largely reliant on the stops in Gironella. Located on the main highway, Cal Rosal has many businesses.
Cal Rosal was centered around an important textile factory until it closed in 1991. Today, there is still an industrial park within the municipality.
