Bottling, Canning & Filling Lines calculator
Cost per Case Calculator
Cost per case is the fully-loaded dollar cost to produce one shippable case of finished product, blending variable packaging and product cost with the fixed costs of setting up and running the order. Plant controllers, line managers and sales teams quoting volume deals rely on it to price accurately and to spot when short runs are being crushed by changeover and QA overhead. On bottling and canning lines, where a single setup can be spread across thousands of cases, the gap between variable and fully-loaded cost per case is exactly where margin is won or lost. This calculator makes that gap explicit.
What this calculator does
- Estimate finished case cost for a bottling, canning, or filling run including variable case cost and fixed setup costs.
- a packaged goods run needs a case-level cost estimate before quoting, scheduling, or approving production
- It multiplies finished cases by the variable cost per case and an allocation share, then adds fixed setup, changeover and QA cost to give total finished-case cost.
Formula used
- Allocated finished case cost = finished cases in the production order × variable packaging and product cost per case × allocation share
- Finished case cost = allocated cost + fixed cost
Inputs explained
- Finished cases in the production order:
- Variable packaging and product cost per case:
- Cost allocation share to this order:
- Fixed setup, changeover, QA or pallet cost:
How to use the result
- Use it when quoting an order, costing a production run, or deciding the minimum batch size that keeps fixed-cost absorption per case acceptable.
- It treats variable cost per case as constant, so it will not capture step-changes like a price break on a component or overtime premiums on a longer run.
Common questions
- How do you calculate cost per case? Multiply finished cases by the variable cost per case, apply the allocation share, then add fixed cost. With 4,200 cases at $8.75 each plus $1,200 fixed, allocated variable cost is $36,750 and total finished-case cost is $37,950, or about $9.04 per case fully loaded.
- What is included in cost per case? Variable elements are product, bottles or cans, closures, labels and corrugate per case. Fixed elements are setup, changeover, QA testing and palletising for the order. This calculator keeps both visible so you see total and per-unit cost.
- Why is my fully-loaded cost per case higher than my BOM? Because the fixed $1,200 of setup, changeover and QA is spread across the cases. At 4,200 cases it adds roughly $0.29 per case, lifting an $8.75 variable cost to about $9.04 fully loaded.
- What is a good cost per case? There is no universal target — it depends on pack size and product. The useful signal is the spread between variable and fully-loaded cost: if fixed overhead adds more than a few percent per case, your run is too short to absorb setup efficiently.
- How does run length affect cost per case? Fixed cost per case falls as cases rise. The $1,200 fixed cost is $0.29 per case across 4,200 cases but would be $1.20 per case across only 1,000 cases, which is why short runs quote higher.
