ROI Calculator
About Tool
Return on Investment (ROI) is the most fundamental metric for evaluating the success of a financial venture. Whether you are tracking the performance of a stock, a real estate flip, or a marketing campaign, this calculator provides the percentage gain or loss relative to the initial cost. It strips away the complexity to show you exactly how hard your money is working for you.
Calculating Your Profitability
To find your ROI, you need two primary figures: the Amount Invested (Cost) and the Amount Returned (Gain). The "Gain" should include the total value of the investment at the time of sale or current valuation, plus any dividends or interest received. Once you hit Run, the tool displays the Total Profit in dollars and the ROI Percentage.
While ROI gives you a snapshot of total growth, it doesn't account for the time it took to achieve that growth. For a more time-sensitive analysis, you might use a CAGR Calculator to see your annual growth rate. Additionally, if you are looking at business returns, you may need to factor in taxes using a VAT Calculator for your sales figures.
Interpreting the Percentage
A positive ROI indicates that the investment is profitable, while a negative ROI means you have lost money. Because it is expressed as a percentage, you can easily compare the efficiency of different investments regardless of their size. For example, a $1,000 investment that returns $1,200 has the same 20% ROI as a $100,000 investment that returns $120,000.
Usage Scenarios

- Stocks/Crypto: Quickly check the performance of a specific trade after fees.
Frequently Asked Questions
Does this include annualization?
No, this is a "simple ROI" calculator that looks at the absolute return. For annualized returns, use a CAGR tool.
What is a "good" ROI?
A "good" ROI is subjective and depends on the risk and the industry. For example, 10% might be great for a low-risk bond but poor for a high-risk startup.
Should I subtract expenses from the 'Amount Returned'?
Yes. To get an accurate Net ROI, ensure the Amount Returned is the final value after all commissions, fees, and maintenance costs are deducted.
Can I use this for rental property?
Yes. Enter your total purchase and renovation costs as the "Amount Invested" and the sale price plus accumulated rent as the "Amount Returned."
