The value product (VP) is an economic concept formulated by Karl Marx in his critique of political economy during the 1860s, and used in Marxian social accounting theory for capitalist economies. Its annual monetary value is approximately equal to the netted sum of six flows of income generated by production:
wages and salaries of employees.
profit including distributed and undistributed profit.
interest paid by producing enterprises from current gross income
rent paid by producing enterprises from current gross income, including land rents.
tax on the production of new value, including income tax and indirect tax on producers.
fees paid by producing enterprises from current gross income, including: royalties, certain honorariums and corporate officers' fees, various insurance charges, and certain leasing fees incurred in production and paid from current gross income.
The last five money-incomes are components of realized surplus value. In principle, the value product also includes unsold inventories of new outputs. Marx's concept corresponds roughly with the concept of value added in national accounts, with some important differences (see below) and with the provision that it applies only to the net output of capitalist production, not to the valuation of all production in a society, part of which may of course not be commercial production at all.
The concept is formulated more precisely when Marx considers the reproduction and distribution of the national income (see e.g. his manuscript called "Results of the Immediate [or Direct] Process of Production", available in English in the Pelican edition of Das Kapital), and also online; and the last chapters of Das Kapital Volume 3).
Marx wrote this in 1864, i.e. about 70 years or so before the first comprehensive Gross National Product and Capital Formation statistics were pioneered by the likes of Wassily Leontief, Richard Stone, Simon Kuznets and Colin Clark (the United Nations standard accounting system was first finalised in 1953).

Intermediate consumption (also called "intermediate expenditure") is an economic concept used in national accounts, such as the United Nations System of National Accounts (UNSNA), the US National Income and Product Accounts (NIPA) and the European System of Accounts (ESA). Conceptually, the aggregate "intermediate consumption" is equal to the amount of the difference between gross output (roughly, the total sales value) and net output (gross value added or GDP). In the US economy, total intermediate consumption represents about 45% of gross output.
Operating surplus is an accounting concept used in national accounts statistics (such as United Nations System of National Accounts (UNSNA)) and in corporate and government accounts. It is the balancing item of the Generation of Income Account in the UNSNA. It may be used in macro-economics as a proxy for total pre-tax profit income, although entrepreneurial income may provide a better measure of business profits. According to the 2008 SNA, it is the measure of the surplus accruing from production before deducting property income, e.
In Marxian economics, surplus value is the difference between the amount raised through a sale of a product and the amount it cost to manufacture it: i.e. the amount raised through sale of the product minus the cost of the materials, plant and labour power. The concept originated in Ricardian socialism, with the term "surplus value" itself being coined by William Thompson in 1824; however, it was not consistently distinguished from the related concepts of surplus labor and surplus product.
