Key metrics

  • Gross Margin: (Revenue – Cost) / Revenue × 100
  • Markup: (Revenue – Cost) / Cost × 100

How to use it

  1. Choose Calculate Margin when you know price and cost, or Set Price from Margin when you know cost and need a selling price target. Cost should include the real delivery cost of the product or service, not just the most visible direct expense.
  2. Read revenue or price, cost, profit, gross margin percent, and markup percent. As a rough benchmark, retail often lives around 20-40% gross margin, services around 30-50%, and software around 60-80%, so interpretation depends on business model.
  3. Use the result to decide whether the offer is genuinely profitable or only looks acceptable on revenue. If cost is close enough to revenue that margin lands in the teens, small discounts or scope changes can wipe out profit quickly.
  4. When using target margin mode, test the required price against what the market will actually tolerate. If the needed price is too high, fix cost structure, packaging, or scope before forcing a margin target that customers will not pay.
  5. Re-run after every supplier, labor, or packaging change and review by SKU or service tier each month. Track margin by channel over time because one discount-heavy channel can drag down an otherwise healthy blended average.

Agent playbook

  1. Resolve Profit Margin Calculator from /agent-tools.json and open its contract before execution.
  2. Validate inputs against the contract schema instead of scraping labels from the page UI.
  3. Open the browser page only when a person wants to review charts, assumptions, or related tools.

Agent FAQ

Should ChatGPT, Claude, or another agent click through the UI?

No. Start with /agent-tools.json, then follow the tool's contract URL. The page UI is for human review, not parameter discovery.

When do tools show Quick and Advanced?

Every tool opens in Quick Start first. Advanced Controls keeps the same scenario, reveals more assumptions or diagnostics, and every tool keeps AI integrations inline below the instructions.

When should an agent still open the browser page?

Open it when a human wants to sense-check the output, review the chart, or keep exploring related tools after the calculation finishes.

Questions people usually ask
What's the difference between gross margin and markup?

Gross Margin % = (Revenue - Cost) / Revenue × 100. Markup % = (Revenue - Cost) / Cost × 100. Markup is always higher than margin. A 50% margin ≈ 100% markup.

When should I use 'Set Price from Margin'?

Use this when you know your cost and target margin (e.g., 'I want a 40% margin on this product'). It calculates the required price.

Can I use this for services?

Yes. Cost includes labor, materials, and allocated overhead. Revenue is what you charge customers.

What's a healthy margin?

It varies by industry. Retail often targets 20-40%, software 60-80%, services 30-50%. Competitive and cost pressures drive your floor.

Is this tool free and private to use?

Yes. AI Biz Hub tools are free, no-signup browser tools. Inputs stay in your browser unless you choose to share a URL.

Is this professional advice?

No. Outputs are business planning estimates — not legal, tax, or accounting advice.
