The return may consist of a gain (profit) or a loss realized from the sale of a property or an investment, unrealized capital appreciation (or depreciation), or investment income such as dividends, interest, or rental income, or a combination of capital gain and income.
In finance, the purpose of investing is to generate a return from the invested asset. Investment science is the application of scientific tools (usually mathematical) for investments. When expenditure and receipts are defined in terms of money, then the net monetary receipt in a time period is termed as cash flow, while money received in a series of several time periods is termed as cash flow stream. From a broader viewpoint, an investment can be defined as 'to tailor the pattern of expenditure and receipt of resources to optimise the desirable patterns of these flows'. If an investment involves money, then it can be defined as a 'commitment of money to receive more money later'. Investment is traditionally defined as the 'commitment of resources to achieve later benefits'. Unsourced material may be challenged and removed.
