What This Calculator Does
The Investment ROI Calculator measures how much profit you earn relative to the amount you invested. Whether you put money into stocks, a rental property, or a small business, ROI tells you the percentage gain or loss on your capital.
How It Works
ROI equals the gain minus the cost, divided by the cost, times 100. This gives you a percentage representing how much your money grew.
Example
You invest $10,000 and sell for $13,500. ROI = (13500 - 10000) / 10000 x 100 = 35%.
Formula
ROI = (gain - cost) / cost x 100Reading the Results

Frequently Asked Questions
Is ROI the same as annual return?
No. ROI measures total return over the entire period. Annual return breaks it down per year.
Can ROI be negative?
Yes. If you lose money, ROI is negative. A $10,000 investment dropping to $7,000 gives -30% ROI.
Does ROI account for inflation?
Basic ROI does not. For inflation-adjusted returns, use the real return calculator.
