About this calculator

Build the cost of one packaging batch from material lines, packing labor and a one-time setup amount. Keep material quantities on a batch basis and finished-package count on a separate denominator.

Inputs

How to use this calculator

Material line

  1. Material quantity for the whole batchUse the purchase unit matching the unit price: boxes, rolls, bags, feet, etc. Do not enter per-package usage here.
  2. Price per material unit (USD)Actual price matching the quantity unit.
  3. Extra material allowance (%)Added to this material line only. Enter zero if its quantity already includes waste.

Shared inputs

  1. Finished packages in this batchUsed for labor and cost per finished package.
  2. Packing minutes per finished packageMeasured direct labor time, excluding any setup already priced separately.
  3. Loaded labor cost per hour (USD)Your actual labor cost; this is not a wage benchmark.
  4. One-time setup / other batch cost (USD)Added once for the entire batch. Avoid costs already included elsewhere.

Enter the shipment or scenario values, then select Calculate result.

Method

Formula and variables

Material cost = sum(batch quantity × unit price × (1 + line allowance ÷ 100)). Labor = package count × minutes per package ÷ 60 × hourly cost. Total = materials + labor + one-time setup. Cost per package = total ÷ finished package count.

Material quantity for the whole batch
Use the purchase unit matching the unit price: boxes, rolls, bags, feet, etc. Do not enter per-package usage here.
Price per material unit (USD)
Actual price matching the quantity unit.
Extra material allowance (%)
Added to this material line only. Enter zero if its quantity already includes waste.
Finished packages in this batch
Used for labor and cost per finished package.
Packing minutes per finished package
Measured direct labor time, excluding any setup already priced separately.
Loaded labor cost per hour (USD)
Your actual labor cost; this is not a wage benchmark.
One-time setup / other batch cost (USD)
Added once for the entire batch. Avoid costs already included elsewhere.

Interpret the result

The total is consumed batch cost. Cost per finished package divides that total by package count; the allowance affects each material line rather than labor.

Outputs: Material, labor, setup and per-package costs

User-cost arithmetic in USD. No live prices, exchange rates, tax, freight charge, equipment depreciation or market wages are inferred. Use consistent batch quantities; do not double count already included materials, waste or labor. No profitability promise.

Worked example

Check the arithmetic

This example uses the starting values shown above. The arithmetic below is calculated independently of the interactive result.

Work through the calculation

  1. Material = 100 × $2 × 1.10 = $220.
  2. Labor = 100 × 2 ÷ 60 × $24 = $80.
  3. Batch total = $220 + $80 + $30 setup = $330; per package = $330 ÷ 100 = $3.30.

Compare the displayed result

Expected displayed result: $330.00

FAQs

Does a 10% material allowance also increase labor?

No. Labor uses package count, minutes per package and hourly cost. The material allowance only changes its own material line.
