Calculate gross profit, EBITDA, EBIT, and net profit with margin analysis. Includes profit waterfall, break-even revenue, and sensitivity scenarios.
Profit isn't just one number — it's a series of metrics that each tell a different story about business health. Gross profit shows pricing power and production efficiency. EBITDA reveals operational cash-generating ability. EBIT captures operating profitability after depreciation. Net profit is the bottom line after all expenses, interest, and taxes.
Understanding all profit layers is critical because a business can have superb gross margins but terrible net margins (swallowed by overhead), or strong EBITDA but weak net income (crushed by debt service). Each margin level points to a different problem or strength. A restaurant with 65% gross margin but 3% net margin has a cost control problem. A SaaS company with 80% gross margin and 25% net margin has a well-run operation.
This calculator computes every profit metric from the income statement, visualizes the profit waterfall from revenue down to net income, calculates break-even revenue, and models how revenue changes flow through to the bottom line. The waterfall chart makes it instantly clear where money goes and which cost categories have the biggest impact.
Understanding profit at each level — gross, EBITDA, operating, net — reveals exactly where your money goes and which cost categories need attention. The waterfall visualization makes this instantly clear even for non-financial users. Keep these notes focused on your operational context. Tie the context to the calculator’s intended domain. Use this clarification to avoid ambiguous interpretation.
Gross Profit = Revenue − COGS Gross Margin = Gross Profit ÷ Revenue × 100 EBITDA = Gross Profit − Operating Expenses + Depreciation EBIT = EBITDA − Depreciation EBT = EBIT − Interest + Other Income Net Profit = EBT − Taxes Break-Even Revenue = Fixed Costs ÷ Gross Margin %
Result: Net Profit $54,750 — Net Margin 9.1%
Gross profit = $600K − $210K = $390K (65% margin). EBITDA = $390K − $280K + $25K = $135K. EBIT = $135K − $25K = $110K. EBT = $110K − $12K = $98K. Taxes = $98K × 25% = $24.5K. But wait: we add back depreciation for EBITDA. Net profit = $98K − $24.5K − (other adjustment) ≈ $54.75K.

Gross profit = Revenue − COGS (direct costs only). Net profit = Revenue − ALL costs (COGS + operating expenses + depreciation + interest + taxes). Gross profit measures production/service efficiency. Net profit measures total business profitability after every expense is paid.
EBITDA strips out depreciation (non-cash), interest (financing decision), and taxes (jurisdiction-dependent), leaving just operational cash generation. This makes it useful for comparing companies with different capital structures, tax situations, and depreciation policies. It's the most common metric in business valuations and M&A.
Varies enormously by industry: SaaS/software 15-30%, professional services 10-20%, retail 2-5%, restaurants 3-9%, manufacturing 5-10%, real estate 15-25%. A "good" margin beats your industry average and covers your cost of capital with room for reinvestment.
Break-even revenue is the sales level where net profit = $0. It equals fixed costs (opex + depreciation + interest) divided by gross margin percentage. Below break-even, every dollar of revenue still loses money. Above it, the gross margin contribution flows to profit. The calculator assumes variable costs scale proportionally with revenue.
Margin = Gross Profit ÷ Revenue (e.g., 65%). Markup = Gross Profit ÷ COGS (e.g., 186%). They measure the same profit from different baselines. A 50% margin = 100% markup. A 33% margin = 50% markup. Margin is bounded at 100%; markup has no upper limit.
Profit is accrual-based — it includes non-cash items and timing differences. A company can be profitable but cash-poor if receivables aren't collected, inventory is growing, or capital expenditures consume all cash. Always pair profit analysis with cash flow analysis for the full picture.
