Welding and fabrication
Fabrication setup batch cost
Allocate setup across batch sizes and find target unit cost volume.
Your inputs
Complete the fields for your selected method. Zero means intentionally zero, not unknown. Currency selection labels amounts; it does not convert exchange rates.
How this calculation works
unit cost=setup/batch+run cost; batch=setup/(target-run cost).
Setup is allocated once; run cost is constant per unit. Whole batch requirement rounds upward. No process qualification or structural design.
What information do I need?
Use records for the same job, equipment or accounting period. Only the fields for your selected entry method are required. An unknown amount is not zero.
Input definitions and where to find them
- One-time batch setup cost (selected currency): One-time whole-batch setup cost from labor/machine records.
- Current batch size (units): Matching invoice, quote, statement, bookkeeping record or explicit budget amount for current batch size. Use the stated period and exclude amounts already counted in another field. Zero means intentionally excluded/not incurred, not unknown.
- Run cost per unit (selected currency): Incremental RUN cost per accepted unit, excluding setup.
- Target total cost per unit (selected currency): Target COST per unit, not target selling price.
Use the Where to find this value controls beside the inputs for available work-it-out helpers. Estimates remain your assumptions; a helper does not verify the source figures.
Worked example
Example amounts use US dollars (USD).
Example answer: Current total cost per unit is $20.00 for the illustrative inputs below.
Example inputs
- One-time batch setup cost: $1,000.00
- Current batch size: 100 units
- Run cost per unit: $10.00
- Target total cost per unit: $15.00
- Current total cost per unit
- $20.00
- Whole batch size for target
- 200 units
These illustrative values are not recommended rates or industry averages. Replace every example input with your own figures.
Use the result well
Allocate setup across batch sizes and find target unit cost volume.
Keep inputs on the same scope and time basis. Calculations retain precision internally; displayed values generally round to two decimal places, with extra precision for very small values and whole-unit rounding where required. Economic comparisons describe your supplied assumptions and do not guarantee future results.
