Tooling and NRE Amortization Per Piece Calculator

Tooling and NRE are real up-front cash. How you recover them, in the piece price or as a separate charge, changes the quote and the risk. This calculator shows the per-piece effect across volumes.

Financing uses a simple average-balance approximation. Contracts may require straight-line recovery over a fixed quantity or a separate tooling invoice.

How to use it

Enter tooling cost, NRE, expected lifetime volume, program length and your cost of capital, plus the production cost of a piece without tooling. The tool adds amortization and an approximate financing charge to reach the full piece cost. Use the chart to show the customer how a higher committed volume lowers the piece price. If the committed volume is uncertain, quote with a lower volume or ask for a separate tooling payment.

Choosing a recovery method

There are three common routes. Customer-paid tooling is billed up front or in milestones and owned by the customer, which removes your risk. Amortized in the piece price spreads the cost but exposes you if volume falls short. A hybrid charges part up front and amortizes the rest. Whatever you choose, record the tooling as an asset and track pieces produced against the amortization quantity. If the contract ends early, a cancellation clause should require the customer to pay the unamortized balance.

  • Use a conservative volume, not the customer's forecast peak
  • Add tooling maintenance and replacement if the tool wears out before end of program
  • Separate NRE from tooling if the customer may fund only one

Common mistakes

Forecast volume is the weakest number. Customers overstate, and the shortfall lands on you. Another mistake is forgetting tool life: a mold rated for 500,000 shots will not cover a million piece program without refurbishment. Teams also leave sampling, first-article and validation runs out of NRE. Finally, review amortization at least yearly, comparing actual pieces shipped with the quantity assumed, so a volume miss is caught while you can still renegotiate.

Frequently Asked Questions

How do I calculate tooling cost per piece?

Divide the total tooling cost, and NRE if you recover it the same way, by the lifetime volume you expect to ship. Add a financing charge if you carry the cost for years before recovering it.

Should I include NRE in the piece price?

Only if the contract says so. Many customers prefer to pay NRE separately as a milestone. Amortizing it in the price is acceptable when volume is committed and cancellation terms cover the unrecovered balance.

What volume should I use?

Use the contractually committed volume if there is one, otherwise a conservative planning figure. Using the optimistic forecast makes the piece price attractive but leaves you with the loss if the program underperforms.

Who owns the tooling?

That depends on the agreement. Customer-owned tooling sits with the customer even if it is in your plant. If you own it, the amortization should be recoverable and the contract should address storage and release at program end.

If tooling and amortization balances live in spreadsheets, we can help track pieces against them directly from your ERP shipments.
