Contract Manufacturing, Job Shop Quoting & Make-to-Order calculator
Job Shop Quote Calculator
Use this calculator to translate available production slots, expected uptime, and first-pass yield into the number of good parts a job shop can confidently quote for a customer-specific order.
What this calculator does
- Estimate quoteable job-shop capacity for a custom part RFQ or make-to-order lot.
- checking whether a requested lot size fits the open shop calendar before sending a quote
- The result estimates how many conforming parts can be promised in the quote window.
Formula used
- Gross quoted part capacity = good parts per production slot × available production slots in the quote window
- Quoteable good parts capacity = gross quoted part capacity × practical shop availability × quoted first-pass yield
Inputs explained
- good parts per production slot: Use the expected good-part output per machine slot, workcell slot, fixture load, or batch for the quoted routing.
- available production slots in the quote window: Count only slots that can realistically be reserved before the requested due date after current backlog and planned downtime.
- practical shop availability: Use realistic availability after setups, programming, changeovers, meetings, maintenance, and operator constraints.
- quoted first-pass yield: Use yield from similar parts, materials, tolerances, inspection plans, and operators.
How to use the result
- Use it to accept, resize, split, or decline an RFQ before committing a ship date.
- 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 job shop quote calculator for? Use this calculator to translate available production slots, expected uptime, and first-pass yield into the number of good parts a job shop can confidently quote for a customer-specific order.
- What information should I enter? Enter good parts per production slot, available production slots in the quote window, practical shop availability, and quoted first-pass yield from the same RFQ, customer order, routing, capacity window, or quote scenario.
- What does the result tell me? The result estimates how many conforming parts can be promised in the quote window.
- 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.
