Illustration 1:

Calculate Return on Investment from the following information:




Capital Employed = Non-current Assets + Current Assets – Current Liabilities

Capital Employed = 1,50,000 + 80,000 – 54,000

Capital Employed = 1,76,000


Return on Investment = 16.47%

Illustration 2:

Calculate Return on Investment from the following information:


The net profit after tax is 1,00,000, and the amount of Tax is 20,000.



Profit before interest and tax = 1,00,000 + Debenture Interest + Tax

= 1,00,000 + 60,000 + 20,000

= 1,80,000

Capital Employed = Equity Share Capital + Preference Share Capital + Reserves + Debentures

= 5,00,000 + 1,50,000 +  2,00,000 + 3,00,000 

= 11,50,000



Return on Investment = 15.65%
