What a part really costs, and what to charge for it

A cost calculator for machine shops. It works out the real cost of a part on your machine (material, cycle time, setup, tooling, machine and operator rate) and suggests a price with markup or margin. A couple of minutes instead of an evening in Excel.

What it does

Six clear blocks, from raw stock to the customer price

Every value updates instantly on any change. These are screenshots of the working application.

1 · Material

Stock, weight and material cost

Pick the stock shape and material. Volume, weight and material cost per part are calculated automatically.

  • Rectangle, round bar, tube or custom weight
  • Stock diagram with L × W × H dimensions
  • Own material database: density and €/kg
Stock, weight and material cost
2 · Machine

An honest hourly machine rate

The rate is built from the real costs of the machine: a commercial rate from its market value and the actual rate from what was really invested.

  • Depreciation, residual value, cost of capital
  • Floor-space rent and maintenance
  • Electricity at rated power or average load

3 · Time and tooling

Cycle time, setup and tool wear

Machining time for side A and B, extra operations and batch setup. Tools are costed by tool life, so every end mill and tap ends up in the part cost.

  • Setup spread over the whole batch
  • Tooling table: price, quantity, life in parts
  • Operator: full time or attendance factor
Cycle time, setup and tool wear
4 · Tooling

Every tool in the part price

Tools come from your own database or are added by hand. The tooling cost per part is shown separately.

  • Price, quantity and tool life in parts
  • Cost per part for each tool
  • Add rows in one click

5 · Cost

Cost per part and per batch

A breakdown into material, machine, operator and tooling with a chart, so you see at once what drives the price and where to save.

  • Cost per part and per batch
  • Share of each cost item in percent
  • Other costs: packaging, coating, delivery

6 · Selling price

Markup, margin or your own price

Choose the method and see the profit per part and per batch, the actual margin and markup, with and without VAT.

  • Markup and margin clearly separated
  • Prices excluding and including VAT
  • Batch profit in plain view
Markup, margin or your own price
Quantity

Price by quantity

One table answers the customer’s «what about 10, or 500?». Setup is spread over each quantity automatically.

  • 1, 4, 10, 25, 50, 100, 250, 500 pcs at once
  • Add your own quantities
  • Cost, price, batch total and profit
