How this service works
Convert markup to margin and back, and get the selling price, from a cost plus one of markup, margin or price.
Output
Returns a structured object with cost, selling price, markup percentage, margin percentage, and profit per unit. Also includes a summary string and optional disclaimer or degraded flag.
Example use cases
Retailer setting price from cost and margin
“I buy widgets at $12.50 each and need a 40% gross margin on the selling price — what should I charge, and what markup percent does that work out to?”
Converting markup to margin for financial reporting
“Our pricing team uses a 60% markup on cost, but our finance team wants the gross margin percentage instead — can you convert 60% markup to its equivalent margin?”
Reverse-engineering margin from known cost and price
“I know my cost is $80 and I'm selling at $120 — what's my gross margin percentage and what markup am I applying?”
Technical details
Endpoint
GEThttps://pricing-math.x402tookit.com/markup-margin?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need to programmatically convert between retail markup and gross margin, or derive a selling price from cost and a target margin or markup. Prefer it over manual formulas when building pricing tools, retail agents, or financial calculators that need reliable, schema-validated results with all three pricing metrics returned together.
Side effects
- Missing required 'cost' parameter returns a validation error
- Supplying more than one of markupPct, marginPct, or price causes ambiguity — only one should be provided
- marginPct >= 100 is mathematically invalid and will be rejected
- Non-numeric values for cost or percentage fields result in schema validation errors
- Payment failure (402) if x402 USDC payment is not included or insufficient
