How do you calculate tooling amortization per part?

Add the one-time tooling cost and setup burden to variable cost times quantity, then divide by quantity. With 100 units at $2.50 each plus $75 tooling and $25 labor/overhead, total is $350 and the amortized cost is $3.50 per piece.

Should tooling be a separate line or amortized into the price?

Amortize it into the piece price when the customer wants one number and you trust the volume; break it out as a separate non-recurring engineering (NRE) line when volumes are uncertain so you recover the tool even if the program is canceled.

What is a good amortization quantity to quote on?

Quote on the firm release, not the customer's optimistic annual forecast. Amortizing $100 of fixed cost over a hopeful 1,000 parts looks great until only 100 ship, leaving you $0.90 per part short on every unit you delivered.

Why is my cost per unit higher than my variable cost?

Because fixed tooling and the labor/overhead adder are spread across each part. In the example, variable cost is $2.50 but the amortized cost is $3.50; the extra $1.00 is the $100 of fixed adders divided across 100 units.

How does order quantity change the amortized price?

Fixed cost per unit falls as quantity rises. The same $100 of tooling and burden adds $1.00 per part at 100 units but only $0.10 per part at 1,000 units, which is why high-volume quotes can underprice short runs dramatically.

Tooling amortization vs. NRE charge: what's the difference?

Amortization recovers the tool gradually inside the per-part price; an NRE charge bills the tool once up front as its own line. Amortization improves the headline piece price but risks under-recovery on short or canceled runs.

Manufacturing Sales Engineering, Estimating & Quoting Operations calculator

Tooling quote amortization Calculator

Tooling amortization is how an estimator spreads the one-time cost of a mold, die, or fixture across the parts that tool will produce, then folds in per-part variable cost and setup burden to land a defensible quote. Sales engineers and quoting teams use it because a $75 fixture is invisible at 10,000 parts but dominates the price at 100. Getting the amortization right is the difference between winning a job at margin and losing it to a competitor who quoted the tooling smarter. This calculator returns both the total cost for the lot and the amortized cost per unit you put on the customer's line.

What this calculator does

Estimate tooling quote amortization for manufacturing sales engineering, estimating and quoting operations using production-ready inputs so teams can quote the work, compare cost scenarios, or review margin risk.
Use it when tooling quote amortization in manufacturing sales engineering, estimating and quoting operations is being quoted and you need a number you can defend on a phone call.
Computes total job cost as quantity times variable cost plus fixed tooling plus the labor and overhead adder, then divides by quantity for an amortized cost per piece.

Formula used

Total tooling quote amortization cost = tooling quote amortization quantity × variable tooling quote amortization cost + fixed tooling quote amortization cost + labor and overhead adder
Cost per unit = total tooling quote amortization cost ÷ tooling quote amortization quantity

Inputs explained

Part order quantity over tool life:
Variable cost per part (material + run time):
One-time tooling and fixture cost:
Setup labor and overhead adder:

How to use the result

Use it when a quote requires customer-specific tooling and you must decide whether to bury the tool in the piece price, charge it as a separate line, or split it across the first release.
It assumes the full tooling cost is recovered over the single quantity you enter; if the customer reorders you overstated the per-unit price, and if they cancel early you under-recovered the tool.

Current U.S. benchmarks

The U.S. prime lending rate is 6.75% (Federal Reserve via FRED, 2026-07-02). Payback and financing math should start from today's rate, not a remembered one.
U.S. manufacturing runs at 75.6% of capacity (Federal Reserve, May 2026). New factory orders are up 2.3% year over year (Census).
