ROI Calculator
Enter what you put in and what you got back to see your ROI — and the annualized rate if it spanned multiple years.
ROI vs annualized ROI
Plain ROI is total return ÷ cost. But a 50% return over five years isn't the same as 50% in one year — so for multi-year holds, the annualized figure (compound annual growth rate) is the fairer comparison. Enter the years held to see it.
