ROI Calculator
Calculate your return on investment (ROI) for any business or personal investment. Enter your investment cost and net profit to see your ROI percentage, profit margin, and get a clear breakdown of your returns. Perfect for entrepreneurs, investors, and business decision-makers.
What Is ROI?
Return on Investment (ROI) is a financial metric that measures the efficiency and profitability of an investment. It calculates the percentage of return relative to the investment cost. ROI is one of the most widely used performance measures in business, finance, and personal investing.
The formula for ROI is:
ROI = (Net Profit ÷ Investment Cost) × 100
Where:
Net Profit = Total Revenue − Total Costs
Investment Cost = Total amount invested
Alternative formula:
ROI = ((Current Value − Cost) ÷ Cost) × 100
A positive ROI means the investment has generated a profit. A negative ROI indicates a loss. The higher the ROI percentage, the more profitable the investment.
How Does the ROI Calculator Work?
The calculator supports two modes:
- Standard ROI: Enter your investment cost and net profit to calculate the ROI percentage, profit margin, and total return.
- Target ROI: Enter your investment cost and desired ROI percentage to calculate the required net profit to achieve that return.
The calculator also computes the profit margin (Net Profit ÷ Total Return) and, if you specify an investment period, the annualized ROI — a compound annual growth rate that makes it easier to compare investments of different durations.

❓ ROI Calculator FAQ
What is ROI?
ROI (Return on Investment) is a financial metric that measures the efficiency and profitability of an investment. It calculates the percentage of return relative to the investment cost.
What is the formula for ROI?
ROI = (Net Profit ÷ Investment Cost) × 100. For example, if you invest $10,000 and earn $3,000 in profit, your ROI is ($3,000 ÷ $10,000) × 100 = 30%.
What is a good ROI?
A good ROI depends on the type of investment and the level of risk. Generally, an ROI above 15% is considered good, while above 30% is excellent. The average stock market return is about 10% annually.
What is the difference between ROI and profit margin?
ROI measures the return relative to the investment cost. Profit margin measures profit as a percentage of total revenue. A company can have a high profit margin but a low ROI if it has a large investment base.
What is annualized ROI?
Annualized ROI (also called Compound Annual Growth Rate) is the average annual return of an investment over a period of time. It allows you to compare investments of different durations on an equal basis.
How do I calculate annualized ROI?
Annualized ROI = ((1 + ROI)^(1/n) − 1) × 100, where n is the number of years. For example, a 50% ROI over 5 years is approximately 8.45% annualized.
What is the difference between ROI and ROE?
ROI (Return on Investment) measures the return on any investment. ROE (Return on Equity) specifically measures the return on shareholders' equity. ROE is used to assess how effectively a company uses shareholders' capital.
What is the difference between ROI and ROA?
ROI measures return on any investment. ROA (Return on Assets) measures how efficiently a company uses its total assets to generate profit. ROA = Net Income ÷ Total Assets.
What is a negative ROI?
A negative ROI means the investment lost money. For example, if you invest $10,000 and lose $2,000, your ROI is -20% ($2,000 loss ÷ $10,000 investment).
How do I use the Target ROI mode?
Enter your investment cost and your desired ROI percentage. The calculator will show you the net profit you need to achieve that target. This is useful for setting investment goals.
What is the difference between ROI and CAGR?
ROI is a simple percentage return over the entire investment period. CAGR (Compound Annual Growth Rate) is the annualized return that smooths out fluctuations over multiple years. CAGR is more useful for comparing investments of different durations.
How does the calculator handle multiple years?
If you select an investment period in the advanced options, the calculator will show the annualized ROI. This gives you the average annual return, making it easier to compare with other investments.
What is the total return?
Total return is the sum of your investment cost and net profit. It represents the total amount you receive back from the investment.
How accurate is this ROI calculator?
This calculator provides accurate results based on standard ROI formulas. However, actual investment returns may vary due to factors like fees, taxes, and market conditions. Always consult with a financial professional for serious investment decisions.
