Profit margin FAQs

What is a good profit margin?

It varies by industry. In Sri Lanka, service businesses often target 20-40% net margins, while retail and manufacturing typically run 5-15%. Compare your margin to industry benchmarks rather than an absolute number.

What is the difference between gross and net margin?

Gross margin is revenue minus cost of goods sold, divided by revenue. Net margin further deducts operating expenses (and in a full analysis, interest and tax). A high gross margin with a low net margin suggests high overhead costs.

Does this include tax?

This calculator shows pre-tax margins. For after-tax net profit, use our Corporate Tax Calculator to apply the applicable CIT rate.
