Break-Even Volume Calculator

Calculate the sales volume needed to recover a fixed tooling investment. Use this as a documented planning estimate, then validate it against the actual machine, mold, resin, and process.

Formula and method

Break-even volume = fixed tooling cost / contribution per part.

Use a real fixed-cost scope, selling price, and variable cost on the same commercial basis.

Inputs and units

Use controlled records, CAD, measured production data, the exact resin data sheet, or machine-maker specifications. Keep the material and time basis with the result.

Worked example

A $80,000 tool with $1.20 contribution per part breaks even at 66,667 parts.

What the result supports

This result is a first-pass screen for costing planning. Use it to identify the next record or engineering check, not as a release decision.

Sanity check

Check the unit basis and whether all quantities describe the same cavity, shot, machine, or production window before comparing values.

Important limitation

Taxes, cash timing, quality claims, freight, and price changes are not included.
