Batch quantity
(N)
Number of good parts in the production run. Setup and tooling are divided by this quantity.
parts
Material cost each
Raw blank or allocated material cost for one part before scrap allowance.
$/part
Setup + programming time
One-time setup, programming, fixturing and proving time for the batch.
min
Setup rate
Hourly rate for setup/programming/fixture work.
$/hr
Cycle time per part
Machine cycle time per good part, including cutting and in-cycle tool changes.
min
Machine shop rate
Loaded hourly rate for the machine: labor, machine, overhead, power, maintenance and burden as you choose to model it.
$/hr
Deburr / inspect time
Per-part secondary time outside the main cycle: deburring, cleaning, inspection, packing or hand work.
min
Secondary rate
Hourly rate for deburr, inspection, finishing or other secondary work.
$/hr
Tooling / fixture cost
Batch tooling, workholding, consumables or special fixture cost to amortize over the run.
$/batch
Scrap allowance
Material scrap/yield allowance applied to the raw material cost.
%
Markup
Cost-plus markup applied after direct cost. Enter 0 for a bare internal cost estimate.

Setup cost is $90.00 total, amortized over 25 parts: $3.60 each.
Tooling/fixture cost is $80.00 per batch: $3.20 each.
Machine cost each = cycle time (hr) × machine shop rate. Keep labor/overhead inside the rate if that is how your shop quotes.
Direct cost each = material + machine + setup + tooling + secondary operations. Quoted price applies cost-plus markup after that direct cost.
