How it works

ROI = (Final − Initial) / Initial ; Annualised = (Final/Initial)^(1/years) − 1
  • Enter initial and final values.
  • Optionally enter years held to get the annualised return.

Worked examples

  • $5,000 → $8,500 total ROI = 70%. Over 5 years, ~11.2% annualised.
  • A 40% total return over 10 years is only ~3.4% per year — context matters.

Frequently asked questions

Does ROI include fees?

It should. Use net figures (after fees, taxes on realised gains) for a realistic number.
