How do you calculate a simpl roi?

To calculate a simple Return on Investment (ROI), use the formula: ROI = (Net Profit / Cost of Investment) x 100. First, determine your net profit by subtracting the total costs of the investment from the total revenue generated. Then, divide the net profit by the cost of the investment and multiply by 100 to express it as a percentage. This calculation helps assess the profitability of an investment.
