''Saving'' differs from ''savings''. The former refers to the act of not consuming one's assets, whereas the latter refers to either multiple opportunities to reduce costs; or one's assets in the form of cash.

variable. This distinction is often misunderstood, and even professional economists and investment professionals will often refer to "saving" as "savings". In different contexts there can be subtle differences in what counts as saving. For example, the part of a person's income that is spent on mortgage loan principal repayments is not spent on present consumption and is therefore saving by the above definition, even though people do not always think of repaying a loan as saving. However, in the U.S. measurement of the numbers behind its gross national product (i.e., the National Income and Product Accounts), personal interest payments are not treated as "saving" unless the institutions and people who receive them save them. Saving is closely related to physical

, in that the former provides a source of funds for the latter. By not using income to buy consumer goods and services, it is possible for resources to instead be invested by being used to produce fixed capital, such as factories and machinery. Saving can therefore be vital to increase the amount of fixed capital available, which contributes to

. If savings are not deposited into a financial intermediary such as a bank, there is no chance for those savings to be recycled as investment by business. This means that saving may increase without increasing investment, possibly causing a short-fall of demand (a pile-up of inventories, a cut-back of production, employment, and income, and thus a recession) rather than to economic growth. In the short term, if saving falls below investment, it can lead to a growth of

and an economic boom. In the long term if saving falls below investment it eventually reduces investment and detracts from future growth. Future growth is made possible by foregoing present consumption to increase investment. However, savings not deposited into a financial intermediary amount to an (interest-free) loan to the government or central bank, who can recycle this loan. In a primitive agricultural economy, savings might take the form of holding back the best of the corn harvest as seed corn for the next planting season. If the whole crop were consumed the economy would convert to hunting and gathering the next season.

would adjust to equate saving and investment, avoiding a pile-up of inventories (general overproduction). A rise in saving would cause a fall in interest rates, stimulating investment, hence always investment would equal saving. But John Maynard Keynes argued that neither saving nor investment was very responsive to interest rates (i.e., that both were interest- inelastic) so that large interest rate changes were needed to re-equate them after one changed. Further, it was the demand for and supplies of stocks of money that determined interest rates in the short run. Thus, saving could exceed investment for significant amounts of time, causing a general glut and a recession.

Saving in personal finance

Within

, the act of ''saving'' corresponds to nominal ''preservation'' of money for future use. A

paying interest is typically used to hold money for future needs, ''i.e.'' an emergency fund, to make a capital purchase (car, house, vacation, etc.) or to give to someone else (children, tax bill etc.). Within personal finance, money used to purchase

s are labeled as ''investment accounts'' by banks for marketing purposes. As a rule of thumb, if money is "invested" in cash, then it is savings. If money is used to purchase some asset that is hoped to increase in value over time, but that may fluctuate in market value, then it is an investment.

Saving in economics

In economics, saving is defined as after tax income minus consumption. The fraction of income saved is called the average propensity to save, while the fraction of an increment to income that is saved is called the marginal propensity to save. The rate of saving is directly affected by the general level of interest rates. The
