Frequently asked questions
How is ROI calculated?
ROI = (value − cost) ÷ cost, shown as a percent, plus absolute profit.
Should cost include fees?
You define cost—purchase plus fees and improvements, or purchase alone. Stay consistent when comparing deals.
What about losses?
If value is below cost, profit and ROI are negative—showing loss relative to cost.
ROI vs CAGR?
ROI is total return between two points—not annualized. The CAGR calculator annualizes. Irregular flows: IRR / NPV.
