ROI Calculator
Enter what you put in and what it is worth now, and see your return on investment as a percentage, your net gain or loss and the return multiple. Add any income you received along the way, such as dividends or rent, and the time you held the investment to get the annualized rate. Everything runs in your browser.
ROI is the net gain divided by the amount invested, so it ignores how long the money was tied up. The annualized figure is the compound annual growth rate: the yearly rate that would turn the amount invested into the total return over the time you entered. Enter costs such as fees, commissions and taxes as part of the amount invested, or take them off the final value, to get the return you actually keep. Past returns do not predict future ones. This is not investment advice.

Math & MoneyAbout the ROI Calculator
Return on investment is the net gain divided by the amount invested. If you put in 10,000 and it is worth 12,500, the gain is 2,500 and the ROI is 25%. Income counts too: a 1,000 investment that is still worth 1,000 but paid 200 in dividends has an ROI of 20%. The return multiple is the total return divided by the amount invested, so 12,500 on 10,000 is 1.25x. A loss gives a negative ROI: 800 back on 1,000 is -20%. Simple ROI ignores time, so a 25% gain over two years is not the same as a 25% gain over six months. The annualized ROI fixes that by finding the yearly rate that compounds to the total return over the time you held the investment, also called the compound annual growth rate. A 25% total gain over 2 years is 11.80% a year, because 1.118 squared is 1.25. Money is handled in whole cents, the simple ROI is exact and rounded to two decimals, and the annualized rate uses one power calculation rounded to two decimals. Fees and taxes are not added for you: include them in the amount invested, or take them off the final value. Nothing you enter is uploaded.
What is the ROI formula?▾
ROI equals the net gain divided by the amount invested, times 100. The net gain is the final value plus any income received, minus the amount invested. For 10,000 invested and 12,500 returned, that is 2,500 / 10,000, or 25%.
What is annualized ROI?▾
It is the yearly rate that would grow the amount invested into the total return over the time you held it, compounded. A 25% total gain over 2 years is 11.80% a year, not 12.5%, because each year's gain also earns a gain. It lets you compare investments held for different lengths of time.
Can ROI be negative?▾
Yes. If the investment is worth less than you put in, plus any income, the ROI is negative. 800 back on 1,000 is an ROI of -20%. Losing everything is -100%.
What is a good ROI?▾
It depends on the risk, the time and what else you could have done with the money, so no single number is good everywhere. Compare investments using the annualized figure, so that a 50% gain over five years (8.45% a year) is not mistaken for a better result than a 20% gain in one year.
Does the calculator include fees and taxes?▾
Not automatically. Add purchase fees and commissions to the amount invested, and take selling costs and taxes off the final value, to see the return you actually keep.
