Net Profit, Net Margin & Corporate EBITDA Income Calculator

Corporate Finance: Navigating the P&L Waterfall

The Income Statement (P&L) tracks how gross top-line revenue flows down to net bottom-line earnings:

• Gross Margin: Measures core product manufacturing/service efficiency.

• EBITDA Margin: Measures core operating cash generation before non-cash and capital structure expenses.

• Net Margin: Measures total bottom-line profitability available to equity shareholders after all operating costs, debt service, and corporate income taxes.

The Formula

Full corporate P&L waterfall & Net Profit equations: Profit = Gross Revenue - Cost of Goods Sold (COGS) = Gross Profit - Operating Expenses (SG\&A) Income (EBIT) = EBITDA - Depreciation \& Amortization (D\&A) Before Taxes (EBT) = EBIT - Interest Expense Income / Profit (\) = EBT - Corporate Income Taxes Profit Margin (\%) = ((Net Income) / (Gross Revenue)) × 100\%

Worked Example

For example, a business with 500,000 revenue, 220,000 COGS (280,000 Gross Profit), 140,000 OpEx (140,000 EBITDA), 20,000 D&A (120,000 EBIT), 12,000 interest (108,000 EBT), and a 21.0% corporate tax rate (22,680 taxes): Net Profit is . The Net Profit Margin is .

Understanding Your Result

EBITDA margin benchmarks by industry: Software/SaaS 20–40%, Healthcare services 10–20%, Retail 8–15%, Manufacturing 12–20%, Professional services 20–35%. EBITDA is not a GAAP metric and excludes capital expenditures — companies with heavy capex requirements (manufacturing, infrastructure) need to evaluate EBIT or free cash flow instead. Net profit margin below 5% indicates thin operating leverage; above 20% suggests strong pricing power or low competition in the niche.
