Contract Manufacturing, Job Shop Quoting & Make-to-Order calculator
Quote Accuracy Score Calculator
Use this calculator to compare accurate quotes against total closed jobs and a target accuracy rate so estimating teams can see whether quote assumptions match production reality.
What this calculator does
- Measure how often quoted jobs stay within expected cost or margin tolerance.
- reviewing estimator performance, routing standards, and closed-job variance
- The result shows quote accuracy percentage and gap to target.
Formula used
- quote accuracy rate = quotes within cost or margin tolerance ÷ closed quoted jobs reviewed × 100
- quote accuracy gap to target = quote accuracy rate - target quote accuracy rate
Inputs explained
- quotes within cost or margin tolerance: Count closed jobs where actual cost, margin, or routing hours stayed within the accepted quote accuracy band.
- closed quoted jobs reviewed: Use the matching population of quoted jobs closed in the same period, customer segment, part family, or estimator group.
- target quote accuracy rate: Use the internal KPI for quotes within tolerance, such as 85%, 90%, or a customer/program-specific target.
How to use the result
- Use it to update costing standards, target estimator coaching, improve routing data, and identify customers or part families with quote risk.
- 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 quote accuracy score calculator for? Use this calculator to compare accurate quotes against total closed jobs and a target accuracy rate so estimating teams can see whether quote assumptions match production reality.
- What information should I enter? Enter quotes within cost or margin tolerance, closed quoted jobs reviewed, and target quote accuracy rate for the same quoting period, customer segment, product family, or closed-job sample.
- What does the result tell me? The result shows quote accuracy percentage and gap to target.
- 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.
