The return is the remuneration of the invested capital, i.e. the remuneration for the investor who decides to deprive himself of immediate consumption and to invest his savings for a certain period of time.
It can be expressed in monetary form or in percentage.
In the first case, the return is equal to the difference between the final wealth generated by the use of resources and the initial investment. The return in percentage form (or rate of return) is obtained by comparing the monetary return to the invested capital.
The yield is the main indicator used to evaluate the goodness of the investment because it provides the economic result that the operation can produce.
