ROI Full Form: Return on Investment
ROI full form is Return on Investment — the percentage gain or loss on an investment relative to its cost, calculated as (gain ÷ cost) × 100.
What is ROI?
Return on Investment (ROI) measures how much you gained or lost on an investment relative to what you put in. The basic formula is ROI = (final value − initial cost) ÷ initial cost × 100. It is an absolute (not annualised) measure.
Why ROI matters
ROI is a quick way to compare the profitability of different investments or expenses. But because it ignores time, a 50% ROI over 2 years is very different from 50% over 10 years — for time-adjusted comparison, use CAGR or XIRR.
Example
If you invest ₹1 lakh and it grows to ₹1.6 lakh, your ROI is (60,000 ÷ 1,00,000) × 100 = 60%. Over 4 years, that is roughly a 12.5% CAGR.

Frequently asked questions
What is ROI full form?
ROI stands for Return on Investment — the percentage gain or loss on an investment relative to its cost.
How is ROI calculated?
ROI = (final value − initial cost) ÷ initial cost × 100. For example, turning ₹50,000 into ₹65,000 is a 30% ROI.
ROI vs CAGR — what's the difference?
ROI is a simple, total percentage return that ignores the holding period. CAGR annualises that return, so it lets you compare investments held for different lengths of time on a like-for-like basis.
