Capture the Real Cost Elements
A reliable job cost has four parts. Material: actual substrate, ink, adhesive and coatings consumed, including makeready and run waste and the value of any unusable remnant. Labor and machine time: hours at each operation using a rate that reflects the full cost of the press or finisher, not just wages.
Outside services: plates, dies, foil, laminating, trade finishing and freight. Overhead: allocated in a way that does not reward running the wrong jobs. If the shop floor does not record start and stop times and material issues per job, the cost is built from standards and you are measuring your estimate, not reality.
- Material issued and returned to stock per job, with waste coded
- Operation start and stop time per press and finishing step
- Outside purchases tied to the job number
- Freight and packing materials charged to the job
The Estimate-to-Actual Report
The most useful single report puts estimated and actual side by side for each job: material cost, run hours, makeready hours, waste percentage, outside services and total, plus the margin each implied. Then group it. By press, to see which equipment is under-recovered.
By job type, such as new versus repeat and short run versus long run. By customer, since a few accounts typically generate the most rework. By estimator, not to blame but to see where standards are off.
Review it monthly while it still matters to the next quote.
Overs, Unders and Quantity Tolerance
Packaging orders carry an agreed tolerance on delivered quantity, and the commercial terms matter to margin. If you overrun 10 percent to be safe and the customer pays for only the ordered quantity, that extra production is a cost. Decide the policy per customer and per product: bill for what ships within tolerance, or absorb overs.
Costing should treat overs as a recorded part of the job so that the true cost per good thousand is visible. Without that, jobs look profitable on paper while the pallets of unsold overs accumulate.

Short Runs, Rush Orders and Hidden Costs
Short runs concentrate cost in makeready and tooling, so a rate that works at 100,000 labels is a loss at 2,000. Rush orders add overtime, disrupted sequences, expedited freight and expedited material, none of which appear if the quote used standard rates. Customer-specific costs also hide: custom packing, labeling of pallets, vendor-managed inventory, and storage of finished goods.
Add a small number of rules in the quoting policy, such as a minimum charge, a rush surcharge, and storage fees after a set period, and then check in the costing report that they were applied.
Using ERP Data Without Another Spreadsheet
If the data lives in your MIS or ERP, the analysis does not have to live in Excel. A question layer can answer: which ten customers had the lowest margin last quarter, how actual waste compares to estimated for film jobs under 5,000 labels, and what happened to margin when we ran the new press. It should show the underlying query and stay read only.
If your costing data is incomplete, start with capturing it. An analysis tool cannot invent numbers that the shop floor never recorded, and a simple monthly report from the MIS may be all you need.
Frequently asked questions
How do I know which jobs lose money in a label plant?
Compare estimated and actual cost per job, then group by job type, press and customer. Short runs, film jobs with tight color targets, and rush orders are common losers. You need actual material and time per job for the comparison to be meaningful.
Should packaging converters use standard or actual costing?
Many use standard costs for quoting and inventory valuation and compare them to actual job costs to see variances. Standards must be revised from actuals regularly or they drift. Pure actual costing exposes problems but needs reliable shop floor data capture.
How should overs be handled in job costing?
Record produced quantity versus ordered and shipped quantity per job, treat overs as part of the cost of the job unless billed, and report cost per good thousand shipped. Set an overs policy per customer in the quote terms so that the commercial treatment matches the costing.
