Quick Answer: Saving is income not spent, or deferred consumption. In economics, a broader definition is any income not used for immediate consumption. Saving also involves reducing expenditures, such as recurring costs. Methods of saving include putting money in, for example, a savings account, a pension account, an investment fund, or kept as cash. In terms of personal finance, saving generally specifies low-risk preservation of money, as in a deposit account, versus investment, wherein risk is a lot higher. Saving does not automatically include interest. 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 flow variable, whereas savings refers to something that exists at any one time, a stock variable.
