In business, total value added is calculated by tabulating the unit value added (measured by summing unit profit [the difference between sale price and production cost], unit depreciation cost, and unit labor cost) per each unit of product sold. Thus, total value added is equivalent to revenue minus intermediate consumption. Value added is a higher portion of revenue for integrated companies (e.g. manufacturing companies) and a lower portion of revenue for less integrated companies (e.g. retail companies); total value added is very closely approximated by compensation of employees, which represents a return to labor, plus earnings before taxes, representative of a return to capital.In economics, specifically macroeconomics, the term value added refers to the contribution of the factors of production (i.e. capital and labor) to raise the value of the product and increase the income of those who own the said factors. Therefore, the national value added is shared between capital and labor.Outside of business and economics, value added refers to the economic enhancement that a company gives its products or services prior to offering them to the consumer, which justifies why companies are able to sell products for more than they cost the company to produce. Additionally, this enhancement also helps distinguish the company's products from those of its competitors.

Hi,
I've had some work done on my central heating system (which has 4 radiators) and need to have new corrosion inhibitor added. What's the typical cost of someone coming to do this - it's a new system (7 months old) so I'm not sure that it needs flushing.
thanks, Adrian
