Frequently asked questions
What is ROI?
ROI (Return on Investment) is the percentage return on an investment. It measures how much you gained or lost relative to the amount invested.
What is CAGR?
CAGR (Compound Annual Growth Rate) is the annualized return rate. It shows the average yearly return equivalent to your total ROI over a given period.
What is the difference between ROI and CAGR?
ROI measures the total return regardless of time. CAGR spreads that return evenly per year, making it easier to compare investments held for different time periods.
Does a positive ROI mean profit?
Yes. A positive ROI means the final value is greater than the investment. A negative ROI indicates a loss.
Does the calculation include fees or taxes?
No. To include costs like brokerage fees, taxes, or transaction costs, subtract them from the profit or add them to the initial investment before calculating.
Can I compare different investments with ROI?
Yes. ROI gives a common metric to compare any investment — stocks, real estate, crypto, or a business. Use CAGR to fairly compare investments held for different time periods.
