Input the total amount you invested initially. This includes the purchase price plus any additional costs like fees, commissions, or improvements.
Input the current or final value of your investment. For stocks, this would be the current market value. For real estate, it would be the current property value.
Enter how long you've held the investment to calculate annualized ROI, which helps compare investments with different time periods.
The calculator will show your total ROI percentage, absolute gain/loss, and annualized ROI if you entered a time period.
Your investment has generated a profit. The higher the percentage, the better your returns relative to your initial investment.
Your investment has lost value. This means you would lose money if you sold at the current value.
This shows your average annual return, making it easier to compare with other investments or benchmarks like the S&P 500 (historically ~10% annually).
ROI doesn't account for inflation, taxes, opportunity cost, or risk. A complete investment analysis should consider these additional factors.
Return on Investment (ROI) is a ratio that measures the efficiency of an investment, calculated as the net profit divided by the cost of the investment. It helps you understand how much profit or loss was generated relative to the amount invested.
Limitations: ROI is a simplified metric and does not account for the time value of money (except in annualized ROI), inflation, risk, taxes, opportunity cost, or other factors important for a full investment analysis.
Enter cost and final value to see ROI and net profit. Add years to annualize returns for fair comparisons.
See plain‑English ROI from cost and outcome. Add a time period to annualize results so you can compare opportunities fairly.
Net gain/loss, ROI% and optional annualized ROI.
Quick notes on positive, negative or flat returns.
Reminds you about fees, taxes and risk (outside the simple model).

Important: This ROI calculator is designed for preliminary investment analysis and educational purposes using standard return on investment formulas and basic financial metrics. While calculations are mathematically accurate for ROI determination, actual investment performance involves complex factors including market volatility, timing of cash flows, tax implications, transaction fees, inflation effects, and risk considerations that are not captured by simplified ROI calculations. ROI is a basic metric that does not account for the time value of money, risk-adjusted returns, or opportunity costs. For investment decisions, portfolio management, financial planning, or business investment analysis, conduct comprehensive financial analysis, consider multiple performance metrics, and consult qualified financial advisors, investment professionals, or certified financial planners who can provide personalized guidance appropriate for your specific financial situation, risk tolerance, and investment objectives.
