Welding & Fabrication calculator
Fabrication Labor Cost Calculator
Estimate fabrication labor cost from labor hours, hourly rate, and support burden. Add quantity, variable cost, labor, and burden to see total cost and cost per piece in one place.
What this calculator does
- Estimate fabrication labor cost from labor hours, hourly rate, and support burden.
- Use it when fabrication labor cost in welding and fabrication is being quoted and you need a number you can defend on a phone call.
- Turns fabrication labor cost quantity, variable fabrication labor cost, fixed fabrication labor cost into a total cost for fabrication labor cost in welding and fabrication.
Formula used
- Total fabrication labor cost = fabrication labor cost quantity × variable fabrication labor cost + fixed fabrication labor cost + labor and overhead adder
- Cost per unit = total fabrication labor cost ÷ fabrication labor cost quantity
Inputs explained
- Fabrication labor cost quantity: Enter the units, parts, kits, assemblies, or jobs covered by the quote or production run.
- Variable fabrication labor cost: Use the per-unit material, labor, test, service, or supplier cost from the BOM, quote, ERP, or cost model.
- Fixed fabrication labor cost: Add setup, tooling, freight, engineering, inspection, or other fixed cost assigned to this calculation.
- Labor and overhead adder: Include labor, burden, handling, testing, or support cost not already captured in the variable cost.
How to use the result
- Use it when fabrication labor cost in welding and fabrication needs a fast quote build-up.
- Tariffs, freight, and packaging are not modeled. Add them as a fixed adder if they apply.
Common questions
- How does this fabrication labor cost calculator help my welding and fabrication team? Estimate fabrication labor cost from labor hours, hourly rate, and support burden. You get a total cost you can defend before quoting, scheduling, or sign-off.
- Where do I get the inputs for this welding and fabrication calculator? fabrication labor cost quantity, variable fabrication labor cost, fixed fabrication labor cost usually move the total cost most. Pull from measured welding and fabrication runs, supplier data, and recent quotes rather than memory.
- What do I do with this number? Use the cost per piece as the floor of the quote, then layer in margin for welding and fabrication risk.
- What should I verify first? Confirm scrap and yield are reflected in variable cost; missing scrap is the usual reason a quote bleeds.
