ROI Formula
Complete Guide: ROI Calculator
Everything you need to know about using this tool effectively
Enter your initial investment cost and the final value or gain to calculate your return on investment as a percentage and in dollar terms. ROI equals the gain minus the cost, divided by the cost, multiplied by 100. This gives you a standardized way to compare the profitability of different investments regardless of their size.
An online financial analysis tool that computes ROI using the standard formula. It takes the total cost of an investment and the total return or final value, then calculates the net profit and expresses it as both a percentage and a dollar amount. The calculator works for stocks, real estate, business projects, marketing campaigns, and any other investment scenario.
Stock Portfolio Analysis
Calculate the return on individual stock picks or your overall portfolio to evaluate whether your investment strategy is working.

View Your ROI
The calculator displays the ROI percentage and net profit amount. Use these figures to compare against other investment options.
Compare ROI across investments of different sizes using the percentage rather than the dollar amount to get a fair comparison.
Factor in all costs including transaction fees, taxes, maintenance, and opportunity cost when calculating true investment cost.
Annualized ROI is more meaningful than total ROI for investments held over different time periods.
A positive ROI means you made money, but compare it to inflation and alternative investments to judge whether the return was worthwhile.
Use ROI as one metric among several. Cash flow, risk level, and liquidity also matter when evaluating investments.
What is a good ROI?
A good ROI depends on the investment type, time horizon, and risk level. The stock market has historically returned about 7 to 10 percent annually after inflation. Real estate investors often target 8 to 12 percent. Higher-risk investments should offer higher ROI to compensate for the additional uncertainty.
How is ROI different from profit?
Profit is the absolute dollar amount earned, while ROI expresses profit as a percentage of the investment cost. A 10,000 dollar profit on a 100,000 dollar investment is a 10 percent ROI, which is more useful for comparing against other opportunities.
Can ROI be negative?
Yes, if the return is less than the cost, the ROI will be negative, indicating a loss. For example, investing 1,000 dollars and receiving 800 back results in a negative 20 percent ROI.
What is annualized ROI?
Annualized ROI adjusts the total return for the length of time the investment was held, expressing it as a yearly rate. This allows fair comparison between investments held for different durations. For example, a 50 percent return over 5 years is roughly 8.4 percent annualized.
Should I include taxes in the ROI calculation?
Yes, for an accurate picture of your actual return, use after-tax figures for both the cost and the gain. Capital gains taxes, income taxes, and property taxes all reduce your effective ROI and should be factored in.
