How to Calculate ROI: Formula, Examples, and Free Calculator

Whether you're running a small business, investing in the stock market, or deciding whether to buy a new piece of equipment, there is one metric that rules them all: Return on Investment (ROI).

ROI is the ultimate measure of profitability. It tells you exactly how much bang you're getting for your buck. In this guide, we'll explain the ROI formula, walk through real-world examples, and show you how to calculate it instantly.

What is ROI (Return on Investment)?

Return on Investment is a financial metric used to evaluate the efficiency and profitability of an investment. It measures the amount of return (profit) generated relative to the investment's cost.

Because ROI is expressed as a percentage, it makes it incredibly easy to compare the profitability of different investments, even if the amounts invested are completely different.

The Exact ROI Formula

To calculate ROI manually, you only need two numbers: your Net Profit and your Total Investment Cost.

Note: Net Profit is calculated by subtracting your total costs from your total revenue (Net Profit = Revenue - Cost).

Real-World ROI Examples

Example 1: The Marketing Campaign

Imagine you run a local bakery and you spend $500 on Facebook ads (your Total Investment Cost). As a direct result of those ads, you sell $1,200 worth of cakes (your Revenue).

• Net Profit: $1,200 - $500 = $700
• ROI: ($700 / $500) × 100 = 140%

Your ROI is 140%, meaning for every dollar you spent on ads, you made your dollar back plus an additional $1.40 in profit.

Example 2: Stock Market Investment

You buy shares in a tech company for $2,000. A year later, you sell them for $2,500.

• Net Profit: $2,500 - $2,000 = $500
• ROI: ($500 / $2,000) × 100 = 25%

How to Calculate ROI Instantly

While the math isn't overly complicated, calculating ROI for multiple scenarios—especially when dealing with complex business expenses, taxes, and ongoing costs—can be tedious and prone to human error.

That's why we built a free, lightning-fast ROI Calculator. Simply enter your total investment amount and your total return, and the tool will instantly calculate your Net Profit and your exact ROI percentage.

What is a "Good" ROI?

A "good" ROI depends heavily on the industry and the risk involved. As a general rule:

• Stock Market: Historically, a 7% to 10% annual ROI is considered solid.
• Business/Marketing: Many businesses aim for a 5:1 ratio (a 400% ROI) on marketing campaigns.
• Real Estate: Investors typically look for a 10% to 15% ROI on rental properties.

Conclusion

Understanding ROI is crucial for making smart financial decisions. By consistently tracking the return on your investments—whether they be time, money, or resources—you can optimize your strategies and grow your wealth faster. Use our free ROI Calculator today to start measuring your success.
