The savings, according to the Keynesian theory, consists of the residual amount to the subtraction on the earnings in a given period of time of the expenses made by a consumer.
For those who are financially prudent, saving - which is income after expenses - is positive. Savings can be transformed into additional income by investing in the financial markets.
Savings and personal finance
In the context of personal finance, the act of saving is the nominal storage of money for its use in the future. An interest-paying deposit account is used by savers, for example, to store useful money for future needs.
