Sheet Metal Costing Workbook
An editable Excel workbook for reviewing sheet-metal material, cutting, forming, welding, finishing, subcontract, overhead, and margin inputs.
What this resource is for
The workbook provides a transparent cost build-up, not a production nesting result. It keeps supplied quantities, material assumptions, process time, outside services, overhead, and commercial margin visible for review.
Use verified nesting, current supplier evidence, machine capability, and shop standards where the job requires them. Replace example values before relying on the result.
Designed for: Sheet-metal fabricators preparing preliminary, reviewable cost estimates from drawings and supplied quantities.
What is included
- job assumptions sheet
- material cost build-up
- process and labour routing
- subcontract and finish costs
- overhead and allowance inputs
- summary and margin review
- example job with formulas
Fields and review points
How to use it
Set the quote basis
Record drawing revision, material specification, quantity, units, supplier evidence date, and whether nesting or yield is preliminary or verified.
Build cost by reviewable component
Separate material, setup, run time, labour, equipment, subcontract, freight, consumables, overhead, and allowances. Avoid a single unexplained cost cell.
Review sensitivity and approval
Check which inputs materially change the result, refresh expired rates, replace preliminary allowances, and record the approved commercial basis before issuing a quote.
Important review boundaries
- The workbook does not generate a machine-ready nest or production instruction.
- Example rates and times are illustrative only.
- Confirm formulas, units, supplier terms, scrap treatment, and tax treatment for the actual business.
Questions about this resource
Does the workbook calculate exact sheet yield?
No. It provides a visible place to enter and review a verified or provisional material basis. Geometry, grain, spacing, remnants, tooling, and shop practice affect actual yield.
Can it be used for laser and plasma work?
The structure can support either, but the estimator must use process-specific setup, run-time, consumable, machine-rate, and nesting evidence.
