Free ROI Calculator Online
Total & annual ROI with inflation-adjusted real returns
The ROI Calculator measures how much you earned (or lost) on an investment relative to what you put in. It calculates both total ROI (the overall percentage gain or loss) and annualized ROI (the equivalent yearly return), which is essential when comparing investments held for different durations.
Frequently Asked Questions
About the ROI Calculator
Return on Investment (ROI) is one of the most widely used metrics in business and personal finance. The formula is simple: ROI = [(Final Value − Initial Investment) / Initial Investment] × 100. But its simplicity can be misleading when comparing investments held for different lengths of time — a 50% ROI over 10 years is far less impressive than a 50% ROI over 2 years.
This is why annualized ROI (CAGR — Compound Annual Growth Rate) is the correct metric for investment comparison. This calculator computes both: total ROI for a snapshot of absolute return, and annualized ROI for fair cross-investment comparison. The inflation-adjusted real return view shows purchasing-power-adjusted outcomes for long-term planning.
ROI is used to evaluate stocks, real estate, business projects, marketing campaigns, and virtually any activity where you put money in and expect more back. A positive ROI means the investment earned more than its cost; a negative ROI indicates a loss. This calculator helps you make that judgment quickly, with the right metric for the comparison at hand.
Formula Used
ROI = [(Final Value - Initial Investment) / Initial Investment] × 100
Annualized ROI = ((Final/Initial)^(1/Years) - 1) × 100
