What is ROI (Return on Investment)?

Return on Investment (ROI) is one of the primary financial metrics to assess an investment's performance. ROI tells you how much you gained (or lost) on your investment relative to what you invested back into the investment stated as a percentage. Whether you're investing in stocks, mutual funds, real estate, startups, or marketing promotions, it's important to calculate ROI to compare investments and successfully measure profitability.

The online ROI Calculator removes the possibility for human error that comes from hand calculating, calculating error, and doing calculations in your head quickly. Once you enter the amount you invested and the returns on that investment, you will get your ROI percentage, the profit or loss amount and the benefit of your time on the investment.

This tool helps investors, entrepreneurs, marketers, and financial planners make data-driven decisions—quickly and without guesswork.

ROI Formula:

The standard ROI formula is:

ROI = (Net Profit ÷ Investment Cost) × 100

• Net Profit = Total Returns – Investment Cost
• Investment Cost = Initial amount you invested
