Common Issues & FAQ
Why is net margin so much lower than gross margin?
Net margin reflects ALL costs: COGS, operating expenses, interest, and taxes. Gross margin only deducts COGS. The gap shows total operating and financial costs.
What's a good net margin?
It varies widely by industry. Tech companies may have 20-30%+, while retailers might only have 2-5%. Compare to industry peers, not across sectors.
Why might net margin fluctuate?
One-time items (restructuring, asset sales, legal settlements), tax rate changes, interest rate changes, and special charges all impact net margin but may not reflect ongoing business.
