About ROI Calculator
Our free ROI (Return on Investment) calculator helps you measure the profitability and efficiency of any investment. Enter your initial investment, final value or gain/loss amount, investment period, and optional additional contributions to instantly see your ROI percentage, annualized ROI, total return, and an investment summary. Compare a rental property held for seven years against an index fund, or check whether a $5,000 ad campaign earned back more than it cost.
The calculator uses the standard ROI formula: ROI % = (Final Value - Total Invested) / Total Invested x 100. For multi-year investments, it also computes the annualized ROI using the CAGR (Compound Annual Growth Rate) formula: ((Final Value / Total Invested)^(1/years) - 1) x 100. This allows you to accurately compare investments with different time horizons on an equal basis.
With support for 40+ world currencies, flexible input modes (enter final value or gain/loss directly), optional recurring contributions, and detailed break-even analysis, this calculator is designed for investors, business owners, financial analysts, and anyone who needs to evaluate investment performance. Your figures are never uploaded or stored.

Understanding ROI Formulas
Basic ROI Formula
ROI (%) = (Final Value - Total Invested) / Total Invested x 100
This formula gives you the total percentage return on your investment. A positive ROI means profit; a negative ROI means loss.
Annualized ROI (CAGR) Formula
Annualized ROI (%) = ((Final Value / Total Invested)^(1/years) - 1) x 100
This formula converts total ROI into an equivalent annual growth rate, making it easy to compare investments with different time horizons.
Use Cases
- Stock Market Investments: Calculate ROI on individual stocks, ETFs, or mutual funds by entering your purchase cost and current portfolio value.
- Real Estate: Evaluate rental property returns by comparing total investment (purchase price, renovations, closing costs) against the current property value or sale price.
- Business Ventures: Measure the return on capital invested in a business, including startup costs, operating expenses, and revenue generated.
- Marketing Campaigns: Determine the ROI of advertising spend by comparing campaign costs against the revenue or leads generated.
- Education Investment: Calculate the return on educational expenses (tuition, books, lost wages) by comparing them to the salary increase gained.
- Cryptocurrency: Track crypto investment returns including dollar-cost averaged purchases with recurring contributions.
- Bond Investments: Evaluate fixed-income returns by entering the purchase price, coupon payments, and final value at maturity.
- Portfolio Comparison: Use annualized ROI to compare the performance of different investment strategies on an equal time-adjusted basis.
Frequently Asked Questions
What is ROI?
ROI (Return on Investment) is a performance metric that measures the gain or loss generated by an investment relative to the amount of money invested. It is expressed as a percentage and is one of the most widely used financial ratios for evaluating investment efficiency.
What is a good ROI?
A "good" ROI depends on the type of investment and the level of risk involved. For the stock market, a 7-10% annualized return is considered strong historically. For real estate, 8-12% annually is often a benchmark. For business investments, ROI expectations vary widely by industry and risk profile.
What is the difference between ROI and annualized ROI?
Basic ROI gives you the total percentage return over the entire investment period regardless of how long it was. Annualized ROI (also called CAGR) normalizes this return to a per-year basis, which lets you fairly compare investments held for different lengths of time. For example, a 50% total ROI over 5 years is an annualized ROI of about 8.45%.
Does this calculator account for taxes and fees?
This calculator measures gross ROI based on the values you enter. To calculate net ROI after taxes and fees, subtract those costs from your final value (or add them to your total investment) before running the calculation.
Tips & Best Practices
- Include all costs: For accurate ROI, include all costs associated with the investment such as transaction fees, commissions, taxes, maintenance, and opportunity costs.
- Use annualized ROI for comparisons: When comparing investments with different holding periods, always use annualized ROI rather than total ROI to get a fair comparison.
- Factor in inflation: Subtract the inflation rate (typically 2-3% annually) from your annualized ROI to understand the real purchasing power gain of your investment.
- Consider risk-adjusted returns: A higher ROI does not always mean a better investment. Consider the risk level -- a 12% return from a stable bond fund may be preferable to a 15% return from a highly volatile asset.
- Track contributions separately: If you make additional investments over time, use the contributions feature to ensure your ROI reflects the return on all capital deployed, not just the initial amount.
- Evaluate multiple scenarios: Run the calculator with different final value assumptions (optimistic, realistic, pessimistic) to understand the range of possible outcomes for your investment.
