How to Calculate ROI
ROI is calculated using a simple formula: ROI = (Net Profit / Investment Cost) × 100. Net Profit is the Total Return minus the Investment Cost. A positive ROI means you made money; a negative ROI means you lost money.
What Is a Good ROI?
A "good" ROI depends entirely on context. Stock market investments average 7-10% annually. Business investments often target 15-30%. Marketing campaigns may aim for 200% or more. Real estate typically returns 8-12% annually. Always compare ROI within the same category.
