Contract Manufacturing, Job Shop Quoting & Make-to-Order calculator
Engineering Quote Burden Calculator
Use this calculator to quantify engineering review time for drawings, tolerances, manufacturability, special processes, fixtures, inspection plans, and customer exceptions in the quoting pipeline.
What this calculator does
- Estimate engineering hours consumed by technical quote reviews.
- sizing engineering support for RFQs and deciding which opportunities require paid engineering review
- The result estimates usable engineering quote hours for the RFQ set.
Formula used
- gross engineering quote hours requested = engineering hours per technical rfq × technical rfqs requiring engineering review
- usable engineering quote hours = gross engineering quote hours requested × engineering availability for quoting × quote reuse and confidence factor
Inputs explained
- engineering hours per technical RFQ: Include drawing review, manufacturability checks, tolerance review, fixture concepts, inspection planning, and customer clarification time.
- technical RFQs requiring engineering review: Count RFQs that need engineering input rather than standard estimator-only pricing.
- engineering availability for quoting: Use the percentage of engineering time realistically available after released-job support, ECOs, troubleshooting, and meetings.
- quote reuse and confidence factor: Use higher values for repeat families and lower values for unfamiliar processes, unclear drawings, or high-risk tolerances.
How to use the result
- Use it to prioritize technical RFQs, schedule engineering reviews, require more customer data, or charge for complex quoting.
- 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 engineering quote burden calculator for? Use this calculator to quantify engineering review time for drawings, tolerances, manufacturability, special processes, fixtures, inspection plans, and customer exceptions in the quoting pipeline.
- What information should I enter? Enter engineering hours per technical rfq, technical rfqs requiring engineering review, engineering availability for quoting, and quote reuse and confidence factor from the same RFQ, customer order, routing, capacity window, or quote scenario.
- What does the result tell me? The result estimates usable engineering quote hours for the RFQ set.
- 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.
