What it does
A factory quote is only the first layer of cost. Freight, duty, fees, packing and defects can cut a margin that looked like 60% to a third of that, and you only find out after the order. This prompt adds each layer, marks which are real quotes and which are guesses, and divides by the units that pass. It then raises costs by 10% to see if the margin survives.
You give it
- Factory price per unit and units ordered (required).
- Freight bill, duty and tax rate (required): the duty rate from your customs broker or the tariff lookup, never from memory.
- Other costs (advised): insurance, packaging, warehouse pick and pack, courier per order.
- Selling price (required): say if tax is in or out. Add your payment fee rate.
- Defect share and target margin (advised).
You get
- Every cost layer, labelled
- Cost per sellable unit
- Margin, price for your target and ad room
- A go, hold or no-go call
Use it when
- You have a factory quote and no true cost yet.
- You are about to place a first order.
- Freight or duty changed and you want the new margin.
