What This Does

Margin is the most important number in any business — and the most commonly confused. Many business owners talk about "making 40% margin" when they mean 40% markup, which is actually a 28.6% margin. Getting this wrong leads to underpriced products, optimistic forecasts, and businesses that are busy but unprofitable. This calculator handles two modes. Revenue & Costs mode takes your total revenue, cost of goods sold (COGS), and operating expenses, then computes your gross margin, operating margin, markup percentage, and the minimum revenue needed to break even on fixed costs. Price a Product mode works in reverse: enter your unit cost and target margin percentage, and it calculates the correct selling price, along with total period profit at your expected unit volume. Both modes include a revenue sensitivity table — showing how a 5–15% change in revenue (from pricing or volume) affects your gross and operating margins — and a comparison against typical industry benchmarks. This makes it easy to see whether your margins are competitive for your sector or whether you're leaving money on the table. Understanding the distinction between margin and markup is foundational: margin is profit divided by selling price; markup is profit divided by cost. A 50% markup produces a 33.3% margin. Confusion between these two is one of the most common and costly pricing mistakes in small business.

When Should You Use This?

→Pricing a new product — calculate what selling price produces your target margin
→Evaluating business health — see if gross and operating margins are on target
→Planning a price change — model how a 5–10% price increase affects profitability
→Comparing your margins to industry benchmarks to identify improvement opportunities
→Finding your break-even point — the minimum revenue to cover fixed operating costs

Example Scenario

Marcus runs a small e-commerce business selling handmade candles. Each candle costs $12 to make (wax, wick, jar, fragrance, labels). He's been selling them for $22 and assuming he has a "good margin." Running the calculator shows his gross margin is actually 45.5% — solid for a product business. But after $4,500/month in operating costs (platform fees, ads, shipping supplies, tools), his operating margin is only 8.2% at 500 units/month. The sensitivity table shows that raising his price to $25 — just $3 more — would push operating margin to 17.6%, nearly doubling his monthly profit without selling a single additional candle.

Frequently Asked Questions

What is the difference between margin and markup?

Margin (or gross margin percentage) is profit divided by selling price. Markup is profit divided by cost. If a product costs $60 and sells for $100, the gross profit is $40. Margin = $40 / $100 = 40%. Markup = $40 / $60 = 66.7%. They measure the same profit but as a percentage of different bases. Using markup percentages when you mean margin — or vice versa — causes systematic pricing errors. This calculator computes both clearly.

What is a good gross margin for my industry?

Margins vary dramatically by industry. Software and SaaS businesses typically see 70–80% gross margins because their marginal cost of delivery is near zero. Retail businesses range from 25–45%. Restaurants show 60–70% gross margin on food and beverage (before labor and overhead), which is why operating margins are often only 3–9%. Manufacturing typically falls between 30–50%. Compare your gross margin to your sector's benchmark before concluding it's adequate — a 40% gross margin is strong in retail but weak in software.

How do I calculate my break-even point?

Break-even revenue is the amount of revenue needed to cover your fixed operating costs given your gross margin percentage. Formula: Break-even = Fixed Costs ÷ Gross Margin%. If your fixed costs are $10,000/month and your gross margin is 40%, you need $25,000/month in revenue to break even — anything above that is operating profit. This calculator computes break-even automatically from your inputs.

Why is my business profitable on paper but cash-poor?

Accounting profit (revenue minus expenses on the income statement) doesn't equal cash in the bank. Timing differences — customers paying on net-30 terms while you pay suppliers immediately, or building inventory before selling it — create gaps between profit and cash. This calculator models income statement margins, not cash flow. If your margins look healthy but cash is tight, you likely have a working capital timing issue that requires separate analysis.
