ROI Calculator — Return on Investment
The ROI Calculator measures the return on an investment as a percentage of the initial cost. ROI is one of the most widely used financial metrics for evaluating the efficiency and profitability of an investment — whether it is a stock, real estate, business, or marketing campaign. A positive ROI means the investment made money; a negative ROI means it lost money.
