Total Return on Investment
How It Works & Calculation Method
Return on Investment (ROI) is the universal profitability metric used across venture capital, real estate, stock portfolios, and digital marketing to evaluate the efficiency of invested capital.
A positive ROI signifies net capital growth, whereas a negative ROI denotes an investment loss. Our calculator computes net profit dollars, total percentage gain, and annualized return efficiency.
The tool subtracts the initial cost of investment from the final proceeds to establish net return.
Net return is divided by initial investment cost and multiplied by 100 to yield the definitive ROI percentage.
Mathematical Formula
ROI (%) = [(Final Value - Initial Investment) / Initial Investment] * 100Worked Example: $10,000 Marketing Campaign Generating $18,000
A digital marketing agency spends $10,000 on advertising that produces $18,000 in gross revenue.
