Does one press stroke equal one good part?

Not necessarily. Convert rated strokes into good stamped parts using the actual parts per stroke and expected rejects before entering capacity.

How do sharpening costs enter the estimate?

Add the planned lifetime sharpening and regrind charges as the maintenance reserve. Keep those charges separate from the initial die construction quote.

Can another part program share the die cost?

Only with a documented allocation between programs. This calculation charges the entire entered construction and maintenance amount to the stated good-part output.

Why does early die retirement increase the allocation?

The same committed die expenditure is recovered from fewer usable stamped parts. Reducing expected life does not reduce the price already paid for the die.

Die Cost per Part Calculator

Price the die burden assigned to each good stamped part over its usable life. Start with the die quote, rated good-part capacity, usable share, sharpening reserve and your permitted allocation.

What this calculator does

Allocate die build and maintenance cost across expected good parts and compare the burden with your quote allowance.

Formula used

Expected good parts = floor(rated good-part capacity × usable life share ÷ 100)
Total die program cost = build cost + maintenance reserve
Die cost per part = total program cost ÷ expected good parts
Maintenance cost per part = maintenance reserve ÷ expected good parts
Allowance headroom = maximum tooling cost per part − calculated cost per part

Inputs explained

Die Build Cost: Quoted total die construction and qualification cost before production.
Rated Good-Part Capacity: Rated lifetime output converted to good parts from the tooling plan.
Usable Share of Rated Life: Expected usable life share from tool history or the program plan.
Die Maintenance Reserve: Lifetime upkeep allowance from your maintenance and supplier cost plan.
Maximum Tooling Cost per Part: Your quote allowance for tooling cost per expected good part.

How to use the result

Best suited to die quote Allowance, shortened die life review.
Part material, production equipment, labor and financing costs are excluded. Usable life is an entered planning estimate, not a predicted failure distribution.

Current U.S. benchmarks

The producer price index for plastic resins and materials stands at 280.569 (BLS, Aug 2026), up 6.6% from a year earlier. Quotes priced off last quarter's material cost miss this move.
The U.S. has 14,378 furniture and related products establishments employing about 355,594 workers (Census County Business Patterns, 2023).
