ROI Calculator
Calculate return on investment and annualized ROI for any investment.
Assumptions used in this calculation
- Simple, non-annualized core ROI: The primary ROI % is a total return over the full holding period; it is not compounded, only the separate annualized ROI figure accounts for holding-period length.
About this calculator
A ₹5,000 gain sounds identical whether it took 3 months or 3 years, but those are very different investments, and comparing them fairly requires more than just looking at the raw percentage return. This calculator takes an initial investment cost and its final value and computes total ROI as (final value − cost) ÷ cost × 100, then also derives an annualized ROI that spreads the total return evenly across the holding period so returns of different lengths can be compared on equal footing. Working this out manually means correctly identifying which number is the base for the percentage and remembering to annualize when comparing across timeframes, both easy to get wrong under time pressure. This calculator is built for comparing the real performance of investments held for different periods, checking whether a deal actually beat a benchmark return, and getting a fast, accurate percentage without spreadsheet formulas.
Worked example
₹10,000 cost, ₹15,000 final value
Result: ROI = 50%
