ROI Calculator
About the ROI Calculator
Return on Investment (ROI) is the percentage gain or loss on an investment relative to what you put in. It is a simple, universal way to measure how well any investment, project or purchase has performed.
Enter the initial amount and the current (or final) value, and the calculator returns the ROI as a percentage.
Frequently asked questions
How is ROI calculated?
ROI % = ((Current value − Initial value) ÷ Initial value) × 100. If you invested ₹1,00,000 and it is now worth ₹1,30,000, the ROI is 30%.
What is the difference between ROI and CAGR?
ROI is the total return over the whole period, ignoring time. CAGR converts that into a per-year rate. A 30% ROI over 1 year is excellent; over 10 years it is modest — CAGR makes that clear.
Can ROI be negative?
Yes. If the current value is less than what you invested, ROI is negative, showing a loss. A drop from ₹1,00,000 to ₹80,000 is an ROI of −20%.
Does ROI account for time?
No — that is its main limitation. Two investments with the same ROI can be very different if one took a year and the other took ten. Use CAGR or XIRR when timing matters.
Should I include costs in ROI?
For a true picture, yes — subtract fees, taxes and other costs from your gain so the ROI reflects what you actually kept, not just the headline change in value.
