ROI Calculator
Calculate return on investment, plus the annualized rate if you held it over multiple years.
How this works
ROI % = (Final value − Amount invested) ÷ Amount invested × 100. Annualized ROI = (Final ÷ Initial)1/years − 1, which accounts for how long the money was invested — the same total ROI over 1 year is much better than over 10 years.
Frequently asked questions
Should I use total ROI or annualized ROI to compare investments?
Annualized ROI, if the holding periods differ — a 50% return over 5 years is far weaker than 50% over 1 year, and only the annualized figure makes that visible.
Does ROI account for taxes or fees?
No — this is a pre-tax, pre-fee gross calculation. Factor those in separately for a realistic net return.
