What this calculator does

It takes your revenue, cost of goods sold (COGS), and operating expenses, then computes gross and net profit, both margins, your break-even revenue, and the revenue required to reach a target profit. This is the "does the business actually work" math.

The formulas

Gross profit = Revenue − COGS · Net profit = Gross profit − Opex
Gross margin = (Revenue − COGS) / Revenue · Break-even = Opex / Gross margin

Worked example

$500,000 revenue, $200,000 COGS, $150,000 opex. Gross profit is $300,000 (60% gross margin); net profit is $150,000 (30% net margin). Break-even is $150,000 ÷ 0.60 = $250,000 of revenue. To hit a $200,000 owner profit, you need ($150,000 + $200,000) ÷ 0.60 = ~$583,000 of revenue.

Assumptions & limitations

  • Treats COGS as fully variable and opex as fixed — a simplification. In practice some costs sit in between.
  • Does not model owner salary separately; include what you pay yourself in opex if you want a clean owner-profit number.
  • Multiples for business valuation (2–4× SDE) are a separate question — see the path page.

FAQ

What is a good profit margin for a small business?
It varies enormously by industry. Service businesses often run 15–30% net margins; retail and e-commerce often run 5–15%; restaurants frequently run 3–6%. The useful question is not "is 20% good" but "is my margin enough to fund growth and pay me."
What is the difference between gross and net margin?
Gross margin is (Revenue − COGS) ÷ Revenue — it measures the core product or service before overhead. Net margin subtracts operating expenses too, so it is (Revenue − COGS − Opex) ÷ Revenue. Net margin is what actually reaches you.
How do I calculate break-even revenue?
Divide your fixed operating expenses by your gross margin. If your opex is $150,000 and your gross margin is 40%, break-even is $150,000 ÷ 0.40 = $375,000 of revenue. Below that, you are losing money.
