ROI Calculator – Return on Investment

About this ROI Calculator tool

ROI (Return on Investment) tells you how much you gained or lost compared with what you put in, as a percentage. It is a quick way to compare different investments, campaigns or purchases.

How to use it

  1. Enter the amount invested and the final value.
  2. Click Calculate.
  3. Read the ROI percentage.

Example

ROI = (Final value − Amount invested) ÷ Amount invested × 100

You invest ₹50,000 and it is worth ₹65,000 later: ROI = 15,000 ÷ 50,000 × 100 = 30%.

Frequently asked questions

Does ROI include the time period?

No. A 30% ROI over one year is very different from 30% over ten years. Use CAGR to compare returns across different periods.

Should I include costs and fees?

Yes. Include all costs to get a realistic ROI.

Can ROI be negative?

Yes. A negative ROI means you lost money.
