ROI Calculator: Measure Your Investment Returns

What is ROI?

ROI (Return on Investment) measures how much profit you make relative to the amount you invested. It is the single most useful number for judging whether a business expense, project, or investment was worth it.

The formula is simple:

ROI = (Net Profit / Total Investment) × 100

A free ROI calculator does this calculation for you instantly, so you can compare dozens of opportunities without touching a spreadsheet.

Why ROI Matters for Business Owners in India

Whether you run a small shop, a startup, or manage your own savings, ROI helps you answer one question: where should my money go next?

• Marketing campaigns — if ₹50,000 spent on ads brought ₹2,50,000 of sales, your ROI is 400%. Compare that against other channels and double down on the winner.
• Inventory decisions — check whether the margin on a product line justifies the money locked in stock.
• Equipment purchases — will that new machine pay for itself in six months or two years?
• Skill courses — the cost of a course against the salary hike it can unlock.

How to Use the ROI Calculator

The ROI calculator needs just three inputs:

1. Amount invested — the total money or resources you put in.
2. Amount returned — what you got back in revenue or profit.
3. (Optional) Period — to see your annualised or total ROI.

Within seconds it shows your ROI percentage and whether the returns are worth the risk, all in our free ROI calculator.

ROI Example

You invest ₹1,00,000 in a small digital marketing setup. Over six months it generates ₹1,60,000 in new sales. Your profit is ₹60,000, so:

ROI = (60,000 / 1,00,000) × 100 = 60%

That is a healthy return. Now compare it against a fixed deposit earning 7% per year, and the investment clearly wins — but the comparison only works when you put a number on it.

ROI vs Profit

ROI is better than plain profit because it is relative. ₹50,000 of profit sounds great, but if you invested ₹10 lakh to earn it, that is a poor 5% return. ROI lets you compare opportunities of very different sizes fairly.
