About This Calculator
ROI is (final value − invested) ÷ invested × 100 — the percentage gain (or loss) relative to what you put in.
If you provide a time period, the tool also computes the annualized ROI (compound annual growth rate), which lets you compare investments of different lengths fairly. The multiplier shows how many times your money grew.

Frequently Asked Questions
What is the difference between ROI and annualized ROI?
ROI is the total return over the whole period. Annualized ROI converts it to a yearly rate, so a 50% return over 2 years and over 1 year are not equivalent.
Can ROI be negative?
Yes. If the final value is less than what you invested, ROI is negative, meaning a loss. The tool reports negative figures clearly.
