How to use it
- Pick the correct mode first: margin to price, markup to price, discount to sale price, or sale price to discount. Then enter cost, list price, sale price, and the relevant percentage so the math reflects whether you are setting a new price, evaluating a markdown, or reverse-checking a quote.
- Read sale price, gross profit, margin percent, markup percent, discount percent, and the formula trace. Use it to catch common interpretation errors, such as assuming 50% markup equals 50% margin when it actually equals a 33.3% margin.
- Treat warnings as decision signals, not cosmetic notes. Margin above 80% often means cost input is incomplete, a discount above 60% usually indicates clearance pricing, and any sale price below cost means the transaction destroys gross profit immediately.
- Use the output to set standard pricing guardrails for sales teams, promo calendars, and quote templates. If a planned discount drops margin below your minimum acceptable threshold, change bundle structure or add value before approving the offer.
- Re-run for every supplier cost change, promo test, or channel-specific price list. Track average realized discount and post-discount margin by channel because discount creep often grows slowly enough to hide until gross profit compresses.

Agent playbook
- Resolve Profit Margin / Markup / Discount Calculator from /agent-tools.json and open its contract before execution.
- Validate inputs against the contract schema instead of scraping labels from the page UI.
- 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 is the difference between margin and markup?
Margin is gross profit as a percentage of sale price, while markup is gross profit as a percentage of cost.
Can this convert discounts too?
Yes. Use list price with discount percent to compute sale price, or reverse-calculate discount from list and sale price.
Does this include VAT or sales tax?
No. This tool models gross pricing only. Tax handling should be applied separately for your jurisdiction.
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.
