Frequently Asked Questions
How do I calculate ROI?
Subtract the amount invested from the amount returned to get net profit, then divide by the amount invested and multiply by 100. For example, turning 1000 dollars into 1300 dollars is a 30 percent ROI.
What is annualized ROI?
Annualized ROI spreads the total return evenly across each year, which lets you compare investments of different lengths. It uses the formula return divided by investment, raised to the power of one over the years, minus one.
Should I include the original amount in the return?
Yes. The amount returned should be the full value you ended up with. The tool subtracts the investment for you to find the net profit.
Can ROI be negative?
Yes. If the amount returned is less than the amount invested, the ROI is negative and the tool labels the result as a net loss.
Is my data sent anywhere?
No. Everything runs in your browser. The numbers you enter never leave your computer and the tool works offline once loaded.
Does ROI account for fees or tax?
Not directly. For a true picture, include any fees in the amount invested and use the after tax value as the amount returned.
