What is Return on Investment - ROI?

A performance measure used to evaluate the efficiency of an investment or to compare the efficiency of a number of different investments. ROI measures the amount of return on an investment relative to the investment’s cost. To calculate ROI, the benefit (or return) of an investment is divided by the cost of the investment, and the result is expressed as a percentage or a ratio.

The return on investment formula:

In the above formula, "Gain from Investment” refers to the proceeds obtained from the sale or use of the investment of interest.

BREAKING DOWN 'Return On Investment - ROI'

Return on investment is a very popular metric because of its versatility and simplicity. Essentially, return on investment can be used as a rudimentary gauge of an investment’s profitability. ROI can be very easy to calculate and to interpret.

What is Net Present Value – NPV?

Net Present Value (NPV) is the difference between the present value of cash inflows and the present value of cash outflows. NPV is used in capital budgeting to analyze the profitability of a projected investment or project. 

The following is the formula for calculating NPV: 


Ct = net cash inflow during the period t

C= total initial investment costs

r = discount rate, and

t = number of time periods 

A positive net present value indicates that the projected earnings generated by a project or investment (in present dollars) exceeds the anticipated costs (also in present dollars). Generally, an investment with a positive NPV will be a profitable.
