FAQ
What is ROI?
ROI (return on investment) measures profit relative to the amount invested, expressed as a percentage.
How do you calculate ROI percentage?
ROI % = (Net Profit ÷ Investment) × 100, where Net Profit = (Final Value − Extra Costs) − Investment.
What counts as “extra costs”?
Any costs tied to getting the return: fees, shipping, commissions, ad spend, taxes, or maintenance—entered as a single total.
Can ROI be negative?
Yes. If your net proceeds are less than your investment, profit is negative and ROI is negative.
What is annualized ROI and when should I use it?
Annualized ROI estimates a per-year return based on the holding period, useful for comparing investments held for different lengths of time.
Is annualized ROI the same as CAGR?
This tool uses a CAGR-like method: (Ending/Beginning)^(1/years) − 1, which assumes compounding over the period.
Why does annualized ROI show as “—” sometimes?
If you don’t enter a valid period, or if the net proceeds are not positive, the annualized calculation is not shown.
