Tube, Pipe & Profile Forming calculator

Labor per Assembly Calculator

Find direct labor cost per accepted tube assembly, including setup labor. Enter accepted quantity, summed production and setup person-hours, an hourly labor rate and your quoted labor allowance.

What this calculator does

  • Allocate measured production and setup labor cost to each accepted tube assembly.

Formula used

  • Total person-hours = production person-hours + setup person-hours
  • Direct labor cost = total person-hours × hourly labor rate
  • Labor cost per accepted assembly = direct labor cost ÷ accepted assemblies
  • Labor budget remaining = budget per assembly − calculated labor per assembly

Inputs explained

  • Accepted Assemblies: Accepted assembly count from the job completion record.
  • Production Labor Time: Sum every worker’s production hours; exclude separately recorded setup.
  • Setup Labor Time: Sum every worker’s tooling change and first-piece approval hours.
  • Blended Hourly Labor Rate: Payroll labor rate, including the burden you choose to allocate.
  • Labor Budget per Accepted Assembly: Direct labor allowance in the quote or job budget.

How to use the result

  • Best suited to assembly quote Review, fixture labor comparison.
  • Material, tooling purchases and machine charges require separate cost allowances.

Current U.S. benchmarks

  • The producer price index for steel mill products stands at 381.162 (BLS, Aug 2026), up 23.4% from a year earlier. Quotes priced off last quarter's material cost miss this move.

Common questions

  • How do I record two workers for one hour? Enter two person-hours. Add each worker’s actual assigned time, even when the workers were present simultaneously.
  • Do rejected assemblies disappear from labor cost? No. Keep their labor in the production hours. Divide the full labor cost by assemblies accepted from that job.
  • Should the hourly rate include benefits? Include the labor burden your costing policy assigns. Keep that basis consistent with the quoted labor budget.
  • Can I enter tooling purchases as setup labor? No. Enter only setup person-hours here. Tooling purchases belong in a separate tooling cost allocation.
