ROI is one of those terms that gets thrown around in boardrooms and startup pitches constantly, but the actual math behind it is pretty simple. It's just: how much did you gain relative to what you spent? The CalcHub ROI Calculator handles the arithmetic so you can focus on the decision — whether you're evaluating a stock, a rental property, a marketing campaign, or a new piece of equipment.

The Formula

ROI = (Net Profit / Cost of Investment) × 100

Or in dollars/rupees: (Final Value - Initial Investment) / Initial Investment × 100

A 50% ROI means for every ₹100 you put in, you got back ₹150. A negative ROI means you lost money.

How to Use the Calculator

Initial investment — total amount spent upfront
Final value or total returns — what you got back (or expect to get)
Time period — optional, used to calculate annualized ROI
Calculate — see absolute ROI%, net profit, and annualized rate if time was entered

Why Annualized ROI Matters

A 40% ROI sounds great — but was that over 2 years or 8 years? Context is everything.

Scenario	Initial Investment	Return	Time	Total ROI	Annualized ROI
Stock trade	₹50,000	₹70,000	2 years	40%	~18.3%
Property	₹20,00,000	₹32,00,000	8 years	60%	~6.1%
Fixed deposit	₹1,00,000	₹1,49,000	5 years	49%	~8.3%

The property looks great at 60% total ROI, but annualized it barely beats a fixed deposit. Annualized comparison levels the playing field.

Beyond the Basic Formula: What You Should Include

For investments: Include dividends, rental income, or any other cash flows received during the holding period — not just the final sale value. For business decisions: Don't forget hidden costs. A ₹5,00,000 machine with ₹8,00,000 in revenue looks great until you add maintenance, operator costs, and downtime. For marketing: ROI on ad spend should include the lifetime value of customers acquired, not just first-purchase revenue. Taxes: Investment returns are often taxable. Real ROI is post-tax. Enter after-tax amounts if precision matters.

A Practical Business Example

A restaurant owner spends ₹80,000 on a delivery app campaign. Over 3 months, they attribute ₹2,20,000 in new orders to it.

Net profit from those orders (after food cost ~40%): ₹1,32,000
ROI = (₹1,32,000 - ₹80,000) / ₹80,000 × 100 = 65%

That's a strong return for a 3-month campaign. But if 30% of those customers were existing ones who would have ordered anyway, the real incremental ROI is lower. Attribution is the hard part of marketing ROI.

What's a "good" ROI?

It depends entirely on the asset class and risk involved. A 7-8% annualized ROI from a diversified equity index fund is considered good over the long term. A 15% ROI on a business investment with significant risk may actually be mediocre when you adjust for that risk. Compare to your alternatives, not to an abstract benchmark.

Can ROI be over 100%?

Yes — it just means you more than doubled your money. A 200% ROI means you tripled it (got back 3x what you invested). In high-risk assets like startup investments or certain stocks, triple-digit ROIs do happen, though so do -100% outcomes.

How is ROI different from IRR?

ROI is a simple point-to-point measure. IRR (Internal Rate of Return) accounts for the timing of cash flows — when you received money during the investment period. For multi-year projects with ongoing cash flows, IRR is more accurate. For simple buy-sell scenarios, ROI is sufficient.
