Tips
Be consistent about which costs you include.
Use total costs for net margin, not only direct product costs.
Compare net profit margin across periods to spot trends.
A positive margin does not always mean cash flow is healthy.
Review margins when salaries, rent, taxes, or supplier costs change.
