Tooling calculator

Tool Amortization Calculator

Spread what the tooling package costs across the parts it will make. Enter the tooling cost, the expected life volume, the annual volume, and annual maintenance to get the loaded per-unit adder.

What this calculator does

  • Tooling and maintenance cost per unit across production volume, with the years needed to recover the tooling.

Formula used

  • Tooling only cost per unit = tooling cost / expected life volume
  • Loaded tooling cost per unit = tooling only + annual maintenance / annual volume
  • Annual recovery = tooling only cost per unit x annual volume
  • Recovery years = tooling cost / annual recovery

Inputs explained

  • Tooling Cost: Capital cost of the tooling package for this part.
  • Expected Life Volume: Units the tooling package will produce over its life.
  • Annual Volume: Units produced in a year at current demand.
  • Annual Tool Maintenance: Yearly upkeep, sharpening, and spare components.

How to use the result

  • Best suited to quoting a part that needs dedicated tooling, comparing fixture packages across volumes, checking tooling payback within the program.
  • Excludes financing cost, tooling interest, and mid-life rebuilds. Assumes annual volume stays inside the expected life volume.

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.
  • The U.S. has 17,154 machine shops establishments employing about 223,303 workers (Census County Business Patterns, 2023).

Common questions

  • How is the tooling adder different from tooling only? Tooling only is the capital divided by the life volume. The loaded adder adds maintenance divided by the annual volume, which is what each part actually carries.
  • Why does the per-unit adder fall as volume rises? Tooling cost is fixed, so a longer life volume divides the same dollars across more units. Maintenance behaves the same way against annual volume.
  • Can recovery years differ from life volume over annual volume? No. The two ratios are algebraically the same: the tooling cost cancels, leaving life volume over annual volume.
  • Does this include regrinding or replacement inserts? No. Those are wear costs that belong with per-part tooling cost. This page amortizes the initial package and its upkeep only.
