Contract Manufacturing, Job Shop Quoting & Make-to-Order calculator
Backlog Value Calculator
Use this calculator to value open customer orders, blanket releases, and unreleased quoted work after applying shippable scope and fixed commercial adders.
What this calculator does
- Estimate open backlog value for contract manufacturing and make-to-order work.
- understanding revenue still to ship and the value tied up in the job-shop backlog
- The result estimates the value of backlog expected to convert to shipment or revenue.
Formula used
- Variable backlog value = open jobs or order lines × average open order value × shippable backlog scope
- Total backlog value = variable backlog value + fixed backlog value adjustment
Inputs explained
- open jobs or order lines: Count open work orders, customer releases, blanket lines, or quoted orders included in the backlog view.
- average open order value: Use net open selling price per order line after discounts, freight terms, and customer-specific commercial adjustments.
- shippable backlog scope: Use the share expected to ship in the period after holds, material shortages, credit issues, and customer delays.
- fixed backlog value adjustment: Include known engineering charges, tooling, expedite fees, customer credits, or commercial adjustments not captured in average order value.
How to use the result
- Use it to plan capacity, forecast revenue, prioritize orders, and identify backlog at 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 backlog value calculator for? Use this calculator to value open customer orders, blanket releases, and unreleased quoted work after applying shippable scope and fixed commercial adders.
- What information should I enter? Enter open jobs or order lines, average open order value, shippable backlog scope, and fixed backlog value adjustment using the same quote revision, customer order, lot size, routing, and cost basis.
- What does the result tell me? The result estimates the value of backlog expected to convert to shipment or revenue.
- 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.
