Notes

The supplier MOQ is 2,500 and the break quantity is 11,346. Ordering the minimum means paying $14.33 a unit for a part quoted at $2.65: 5.41 times, the worst on this shelf, and the reason is a $26,000 tool against a part that costs under three dollars to make.


Even at 113,460 units, ten times the break quantity, the landed price is $2.65 against a $2.20 tier rate. A Class 103 tool is a commitment to a volume, and this part is the argument for asking whether that volume exists before the tool is cut.

MILLWRIGHT

A contract manufacturing template that prices the order against the rate you were quoted, and names the quantity at which the two stop disagreeing.

Every figure on this site is computed in the browser from the numbers in the fields, and nothing is sent anywhere. The model prices the quotation as typed: it cannot see a supplier renegotiating a tier, a tooling charge amortised across several customers’ orders, or a minimum that is really a scheduling preference. Duty is charged on cost of goods before freight, so a buyer on a different incoterm is on a different number.
