How this calculator works
ROI expresses the gain or loss as a percentage of the initial amount invested, helping compare opportunities of different sizes.
Net gain = Final value + Income − Costs − Initial investment. ROI = Net gain ÷ Initial investment × 100.
An initial Rs. 1,000,000 investment ending at Rs. 1,180,000 with Rs. 50,000 income and Rs. 20,000 costs returns Rs. 210,000, or 21%.
FAQ
