ROI Calculator: Investment Return and Annualized Growth
Enter the initial investment, ending asset value and holding period. Add cash income and fees only when they are not already included in those values. The result separates profit, total ROI and annualized growth.
Reviewed and updated:Annualization treats the ending value and cash income as one ending amount. Cash-flow dates and reinvestment are not modeled; this is not IRR.

Formula and assumptions
Cost C = initial investment + additional fees. Returned amount V = ending value + cash income. Net profit = V − C. ROI = (V − C) ÷ C × 100. Equivalent annualized return = ((V ÷ C)^(1 ÷ years) − 1) × 100.
03
Worked example
$10,000 growing to $12,100 over two years, with no additional income or fees, gives a $2,100 profit, 21% total ROI and 10% equivalent annualized growth.

FAQ
Frequently asked questions
Should I add dividends that are already in the ending value?
No. Enter only cash income that is not already included in the ending asset value. Likewise, add only fees not already included in your initial investment, to avoid counting an amount twice.
Is annualized return total ROI divided by years?
No. Annualization uses compound growth. A 21% gain over two years corresponds to 10% per year, because 1.10 × 1.10 = 1.21.
Can I calculate losses?
Yes. An ending amount below your total cost gives a negative return. Losing the entire investment gives −100%. The model does not cover leveraged losses beyond the amount invested.
