The ROI formula is calculated by dividing total profit by total investment and then multiplying the result by 100 to get a percentage. The formula is:
ROI = (Total Profit / Total Investment) * 100
This percentage represents how much profit you earned for every dollar you invested. For example, if you invested $5,000 and earned a profit of $2,000, your ROI would be 40%. This means you made a 40% return on your investment, which indicates a profitable venture. A positive ROI indicates profitability, while a negative ROI suggests that adjustments may be needed in your investment strategy.
