About this calculator
ROI pages are useful because they reduce a wide range of projects and investments to one comparable return metric.
Including extra costs helps keep the result practical instead of pretending the initial ticket size is the full cost basis every time.
Frequently asked questions
Why include additional costs?
Because fees, setup costs, and carrying costs often change the true return materially.
Can ROI be negative?
Yes. If the final value is below the total money invested, ROI is negative.
Does ROI capture time automatically?
No. It is a return ratio, so time still needs separate interpretation when comparing long and short projects.
