Contract Manufacturing, Job Shop Quoting & Make-to-Order calculator
Lot Size Economics Calculator
Use this calculator to scale per-unit lot-size savings or penalties across the quoted quantity while accounting for yield and pricing capture.
What this calculator does
- Estimate lot-size economic benefit or cost impact for a quoted run.
- comparing small lots, economic lots, blanket releases, and production batch sizes
- The result estimates the lot-size cost or savings captured in the quote.
Formula used
- gross lot-size economic impact = lot-size cost impact per unit × quoted lot size
- lot-size economic impact captured = gross lot-size economic impact × usable lot yield × cost impact captured in price
Inputs explained
- lot-size cost impact per unit: Use the per-unit setup absorption, material breakage, handling, inspection, or scheduling impact compared with the baseline lot size.
- quoted lot size: Use the batch quantity, release quantity, or make-to-order lot size being compared.
- usable lot yield: Use expected good-unit yield after scrap, rework, first article, inspection, and handling loss.
- cost impact captured in price: Use 100% when the quote fully recovers the lot-size impact or less for negotiated pricing.
How to use the result
- Use it to pick quote quantities, set price breaks, justify MOQs, and compare batch-size alternatives.
- Treat the result as an estimate until the RFQ package, customer drawing revision, material quote, routing, setup standard, shop rate, outside service quote, scrap history, open capacity, due date, and quoted commercial terms are confirmed for the same job, lot size, and customer order.
Common questions
- What is the lot size economics calculator for? Use this calculator to scale per-unit lot-size savings or penalties across the quoted quantity while accounting for yield and pricing capture.
- What information should I enter? Enter lot-size cost impact per unit, quoted lot size, usable lot yield, and cost impact captured in price from the same RFQ, customer order, routing, capacity window, or quote scenario.
- What does the result tell me? The result estimates the lot-size cost or savings captured in the quote.
- When is the result only an estimate? Treat the result as an estimate until the RFQ package, customer drawing revision, material quote, routing, setup standard, shop rate, outside service quote, scrap history, open capacity, due date, and quoted commercial terms are confirmed for the same job, lot size, and customer order.
