ROI Calculator

Return on investment — total and annualized. Net Gain / Loss = Final Value - Initial Investment; Total ROI = (Final Value - Initial Investment) / Initial Investment * 100; Annualized ROI = ((1 + (Total ROI / 100))^(1 / Holding Period) - 1) * 100 How it works Include transaction fees, maintenance, taxes and other costs that belong in the cost basis. Annualized ROI helps compare different holding periods, but it does not describe volatility, cash-flow timing, taxes or risk. There is no universal good ROI: an appropriate benchmark depends on the asset, risk, liquidity, fees and alternatives available to you. Validation: Initial investment must be greater than zero and holding period must be positive. A total return at or below −100% cannot be annualized with the geometric formula.
