How do you calculate service bureau backlog value?

Multiply the number of backlog jobs (or booked hours) by the average value per job, then by your conversion probability, and add the coordination burden. With 34 jobs at an effective $665.65 each and 90% conversion you get $22,032 of captured value; adding the $600 coordination burden gives $22,632.

What's a good conversion probability for AM backlog?

Firm POs sit near 95-100%; verbally confirmed or deposit-pending work is often 80-90%; soft quotes you'd exclude entirely. The 90% default suits a queue that's mostly confirmed with a little softness.

Why weight backlog by probability instead of counting it raw?

Because a raw count assumes every job runs, which overstates committed revenue and leads to over-investing in capacity. Weighting by 90% trims the $24,480 raw figure down to a planning-grade $22,032 of captured value.

Should I measure backlog in jobs or in machine hours?

Use booked machine hours if your constraint is printer capacity and jobs vary wildly in run time; use job count if values are more uniform. The calculator handles either by switching what the first two fields mean.

What is the coordination burden line for?

Managing a backlog isn't free — scheduling, customer status updates, re-prioritizing the build calendar and chasing material all cost time. The $600 flat figure represents that fixed overhead of carrying the queue.

Backlog value vs. booked revenue — are they the same?

No. Booked revenue is what you've invoiced; backlog value is committed work not yet run, risk-adjusted for the chance it converts. This tool gives the forward-looking number, not the recognized one.

Additive Manufacturing Service Bureau Quoting calculator

Service Bureau Backlog Calculator

Service Bureau Backlog value is the risk-adjusted dollar total of all confirmed and near-confirmed additive jobs waiting in your queue. Owners, production planners and sales leads use it to size committed revenue, justify adding a printer or a shift, and decide how aggressively to chase new quotes. It matters because raw backlog counts overstate reality — not every booked job runs, customers cancel, and some 'confirmed' work is still soft — so weighting the queue by a conversion probability gives a number you can actually plan capacity and cash flow against. This calculator also adds the fixed coordination burden of managing a queue, which a simple job-count never shows.

What this calculator does

Estimate dollar value tied up in quoted or booked AM backlog from backlog units, average value, probability capture, and fixed backlog burden.
an operations lead needs to connect backlog value with capacity and quote commitments
It computes risk-adjusted backlog value by multiplying open backlog jobs or booked hours by the average value per job and a conversion probability, then adding a flat coordination/scheduling burden.

Formula used

Captured backlog value = backlog jobs or hours × average backlog value × probability/capture
Service bureau backlog value = captured backlog value + coordination burden

Inputs explained

Open backlog jobs or booked print hours:
Average value per backlog job:
Backlog conversion probability:
Backlog coordination and scheduling burden:

How to use the result

Use it for monthly capacity planning, investment decisions, or whenever you need to report committed pipeline value to ownership or a lender.
A single conversion probability flattens a queue that really contains both firm POs and soft holds; for a precise view, segment the backlog and run firm and tentative work separately.

Current U.S. benchmarks

The producer price index for plastic resins and materials stands at 319.371 (BLS, May 2026), up 19.5% from a year earlier. Quotes priced off last quarter's material cost miss this move.
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.
