Show what one sale actually leaves after every cost. FREE. Subtracts supplier cost, shipping, payment fees, the ad spend that found the buyer, and anything else — then reports the break-even price so you know how much room there is. Typical input {"sell_price": 39.99, "supplier_cost": 12.4, "shipping_cost": 4.2, "ad_cost_per_order": 9} returns {"revenue": 39.99, "total_cost": 27.06, "profit": 12.93, "margin_pct": 32.33, "markup_pct": 222.5, "break_even_price": 27.06, "biggest_cost": "supplier_cost"}. Use before listing a product. Not for a whole tiered price list — that is price_ladder — and not for the effect of returns, which is returns_impact. Errors: on invalid, missing, or malformed input this tool never raises a protocol error — it returns {"error": "<what is wrong and how to fix it>"}. Every call is read-only and idempotent, so after correcting the input it is always safe to retry.
