Formula used
Net Profit Margin (%) = (Net Profit ÷ Revenue) × 100
When using the detailed build, net profit is computed as: Revenue − COGS − Operating Expenses − Interest − Taxes + Other Income − Other Expenses + Adjustments
Revenue should reflect net sales for consistent comparisons.

FAQs
1) What does net profit margin tell me?
It shows how much profit remains after all expenses, for each unit of revenue. Higher margins usually mean better pricing power, cost control, or both.
2) What revenue number should I use?
Use net sales or net revenue for the period. If you have returns and allowances, subtract them from gross revenue to avoid overstating margins.
3) Can net profit margin be negative?
Yes. A negative margin means the business made a net loss. The calculator supports negative net profit to reflect loss periods accurately.
4) Why does the detailed build show more margins?
When you enter COGS and operating costs, the calculator can estimate gross, operating, and pre-tax margins. These help you locate where profitability is gained or lost.
5) How should I treat one-time items?
Use the adjustments field to add or remove unusual gains or losses. This can help compare periods more fairly, but document what you adjusted for transparency.
6) Are higher margins always better?
Not always. Very high margins can reflect underinvestment, temporary pricing, or accounting timing. Compare with industry context, growth goals, and cash flow.
7) How do I set good benchmark bands?
Start with your historical averages, then set low and high bands around your expected range. Update them as pricing, costs, and market conditions change.
8) Does this replace financial statements?
No. It’s a quick analysis tool for planning and review. Always reconcile inputs with your income statement and accounting policies for final reporting.
