Investment Formula

Return on Investment ( ROI ) = Return / Cost of Investment

Investment Formula Examples

Corporation ABC has invested \$1,200,000 for new investment opportunity.  At the end of the financial period, corporation ABC obtained \$240,000 revenue and \$120,000 net profit. The return on investment ( ROI ) calculation can be performed as following.

Return on Investment ( ROI ) = Revenue / Cost of Investment = 240,000 / 1,200,000 =  0.2 or 20%

If the accountant uses revenue as the input for return, Corporation ABC managed to earn 20% from its cost of investment. The return on investment ( ROI ) for corporation ABC is 0.2 or 20%. However, net profit can be used as input for return too.

Return on Investment ( ROI ) = Net profit / Cost of Investment = 120,000 / 1,200,000 =  0.1 or 10%

In this case, the return on investment ( ROI )  for corporation ABC is 10% when net profit is used as input for return.If the accountant would like to have better perception on the return on investment ( ROI ) for corporation ABC, he will use revenue as input for return instead of net profit. Hence, it is vital for investors to know what are the inputs for the return on investment ( ROI ) formula.
