Frequently asked questions

What is net profit?

Net profit is what remains after you subtract cost of goods, operating expenses, and tax from revenue. If revenue is 100,000, COGS 40,000, operating expenses 30,000, and tax 7,500, net profit is 22,500. It answers how much the business kept for that period after those costs, not how much margin one product has.

How is this different from the Profit Margin Calculator?

The Profit Margin Calculator is for unit pricing: cost and selling price of one item, with margin and markup. This Net Profit Calculator is for a period P&L-style stack: total revenue minus COGS, operating expenses, and tax. Use margin for shelf or quote pricing; use net profit for “did the business make money this month?”

What should I include in operating expenses?

Put recurring run-the-business costs that are not COGS: rent, utilities, software, marketing, wages, insurance, and similar. Keep product or job direct costs in COGS. You can enter one combined operating total; this tool does not split categories.

Does the tax rate match my country’s tax?

No. The tax field is a simple percentage applied to positive operating profit only. It is not GST, VAT, income tax, or payroll tax modeling. Use a rate that matches how you want to estimate, or leave it at 0 and handle tax separately.

Is this financial or tax advice?

No. Results are general arithmetic for education and planning only. Speak with a qualified adviser for business or tax decisions.
