Return on Investment

Return on Investment (ROI) – a ratio that indicates how efficiently investments are used in terms of earning income (return to stockholders). It reflects the amount of earned profit in relationship to total investments (long-term liabilities and equity).

Return on Investment = Net Income before Noncontrolling Interest and Nonrecurring Items + Interest Expense ÷ Average (Long-Term Liabilities + Equity)

Example:

Return on Investment (Year 1) = 480 ÷ 1040 = 0,46 = 46%

Return on Investment (Year 2) = 474 ÷ 1062 = 0,44 = 44%

Firm’s return on investment was 0,46 in year 1. Year 2 witnessed a slight decrease of this ratio to 0,44. This means, that the ability of investments (long-term liabilities plus equity) to generate the net income has declined.
