How do you calculate backlog value?

Multiply open orders by average order value and by the shippable share, then add any fixed adjustment. With 72 orders at $6,400 average, an 88% shippable share, and a $15,000 adjustment, total backlog value is $420,504.

What does the shippable share percentage do?

It discounts the backlog for orders that are on hold, awaiting customer approval, or otherwise not yet shippable. At 88%, you're recognizing only the portion you can realistically convert, trimming the variable backlog to $405,504 before the fixed adjustment.

Why include a fixed backlog value adjustment?

To capture value that doesn't scale with order count, a large committed contract booked separately, a known cancellation, or a milestone payment. In the example a $15,000 addition lifts total backlog to $420,504.

Is backlog value the same as revenue?

No. Backlog value is contracted but unearned work; revenue is recognized only as jobs ship. A healthy backlog signals future revenue, but it isn't booked until the product leaves the dock.

What is a healthy backlog for a job shop?

A common rule of thumb is roughly four to twelve weeks of capacity-worth of backlog. Too little risks idle machines; too much signals stretched lead times that can cost you orders. Read backlog value against your weekly shipping capacity, not in isolation.

Backlog Value Calculator

Backlog Value puts a single dollar figure on your open order book by combining how many jobs are open, what they're worth on average, and how much of that work is actually shippable. Owners, planners, and CFOs in contract manufacturing use it to gauge committed revenue, plan capacity, and brief lenders or buyers on the pipeline. A raw order count tells you activity; backlog value tells you cash that's contracted but not yet earned. Tracking it weekly shows whether the shop is filling or draining its order book.

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
It computes total backlog value as open orders times average order value times the shippable share, plus a fixed adjustment for known additions or write-offs.

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 in the backlog:
Average revenue per open order:
Share of backlog that is shippable:
Fixed backlog value adjustment:

How to use the result

Use it at week-end or month-end to report committed revenue and to forecast whether capacity matches the order book.
It uses a single average order value, so a backlog dominated by a few large jobs or skewed by outliers can mislead; segment by order size or customer for a sharper read.

Current U.S. benchmarks

The U.S. prime lending rate is 6.75% (Federal Reserve via FRED, 2026-07-02). Payback and financing math should start from today's rate, not a remembered one.
