On this instance, the wheat is an intermediate good. It’s used to supply flour, which is then used to supply bread. The worth of the wheat is included within the calculation of GDP when the bread is bought to customers.
Nonetheless, the worth of the wheat shouldn’t be included within the calculation of GDP when the farmer sells it to the miller, or when the miller sells the flour to the baker. It is because the worth of the wheat is already included within the worth of the bread.
By excluding intermediate items from the calculation of GDP, we keep away from double counting and be certain that solely the worth of ultimate items and companies is counted. This offers us a extra correct measure of the whole worth of products and companies produced in an financial system.
