The source adds the following: Gross output is principally a measure of sales or revenue from production for most industries, although it is measured as sales or revenue less cost of goods sold for margin industries like retail and wholesale trade. Intermediate inputs are the foreign and domestically-produced goods and services used up by an industry in the process of producing its gross output. Value added is the difference between gross output and intermediate inputs and represents the value of labor and capital used in producing gross output.
