Investment or investing is a term with several closely-related meanings in business management, finance and economics, related to saving or deferring consumption.

Investment is the choice by the individual to risk his savings with the hope of gain. Rather than store the good produced, or its money equivalent, the investor chooses to use that good either to create a durable consumer or producer good, or to lend the original saved good to another in exchange for either interest or a share of the profits.

In the first case, the individual creates durable consumer goods, hoping the services from the good will make his life better. In the second, the individual becomes an entrepreneur using the resource to produce goods and services for others in the hope of a profitable sale.

The third case describes a lender, and the fourth describes an investor in a share of the business.

In each case, the consumer obtains a durable asset or investment, and accounts for that asset by recording an equivalent liability. As time passes, and both prices and interest rates change, the value of the asset and liability also change.

An asset is usually purchased, or equivalently a deposit is made in a bank, in hopes of getting a future return or interest from it. The word originates in the Latin "vestis", meaning garment, and refers to the act of putting things (money or other claims to resources) into others' pockets.

The basic meaning of the term being an asset held to have some recurring or capital gains. It is an asset that is expected to give returns without any work on the asset per se.

The investment decision (also known as capital budgeting) is one of the fundamental decisions of business management: Managers determine the investment value of the assets that a business enterprise has within its control or possession.

These assets may be physical (such as buildings or machinery), intangible (such as patents, software, goodwill), or financial. Assets are used to produce streams of revenue that often are associated with particular costs or outflows.

All together, the manager must determine whether the net present value of the investment to the enterprise is positive using the marginal cost of capital that is associated with the particular area of business.

In terms of financial assets, these are often marketable securities such as a company stock (an equity investment) or bonds (a debt investment).

At times the goal of the investment is for producing future cash flows, while at others it may be for purposes of gaining access to more assets by establishing control or influence over the operation of a second company (the investee).

In finance, investment is the buying securities or other monetary or paper (financial) assets in the money markets or capital markets, or in fairly liquid real assets, such as gold, real estate, or collectibles.

Valuation is the method for assessing whether a potential investment is worth its price. Returns on investments will follow the risk-return spectrum.
