''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. Saving refers to an activity occurring over time, a

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.
