📐 Formula & How It Works
ROI Percentage Formula
Net Profit / Loss Formula
ROI (Return on Investment) measures the efficiency of an investment by comparing the net gain or loss to the original cost. A positive ROI indicates profit, while a negative ROI indicates a loss. The formula is standardized across finance, business, and marketing contexts worldwide.
📊 Practical Examples
🇮🇳 Example 1 — Indian Stock Investment
Rahul invested ₹1,00,000 in a mutual fund. After one year, the value grew to ₹1,18,000.
Net Profit = ₹18,000 | ROI = 18%
🇮🇳 Example 2 — E-commerce / Dropshipping Campaign
Priya spent ₹25,000 on Facebook ads for her dropshipping store and earned ₹72,500 in revenue.
Net Profit = ₹47,500 | ROI = 190%
🇺🇸 Example 3 — US Real Estate Investment
James purchased a rental property for $200,000 and sold it for $260,000 after 3 years.
Net Profit = $60,000 | ROI = 30%
🇮🇳 Example 4 — Negative ROI (Loss Scenario)
Amit invested ₹50,000 in a startup that returned only ₹35,000.
Net Loss = −₹15,000 | ROI = −30%
📖 What Is an ROI Calculator?
An ROI (Return on Investment) Calculator is a financial tool that helps individuals and businesses measure the efficiency and profitability of an investment. By comparing the net gain or loss against the initial investment cost, you get a standardized percentage that makes it easy to compare different investment opportunities.
Whether you are evaluating a marketing campaign, a stock portfolio, a real estate deal, or a business venture, the ROI metric gives you a quick and clear snapshot of performance. A higher positive ROI means more efficient use of your capital, while a negative ROI signals a loss that may require strategic adjustment.
This tool is especially valuable for entrepreneurs, marketers, dropshippers, and investors in India and globally who want to make data-driven decisions without complicated spreadsheets or financial software.
