Capital formation

n. transfer of savings from private people and governments to the business sector for investment

Capital formation is a term used in national accounts statistics and macroeconomics. It basically refers to the net additions to the (physical) capital stock in an accounting period, or, to the value of the increase of the capital stock; though it may occasionally also refer to the total stock of capital formed. Thus, in UNSNA, capital formation equals fixed capital investment, the increase in the value of inventories held, plus (net) lending to foreign countries, during an accounting period. Capital is said to be "formed" when savings are used for investment purposes, often investment in production.
