Injection Moulding Part Cost Calculator
What should one moulded part cost? Build the four-part formula from our part cost guide: material + machine time + mould amortisation + extras. Every input maps to a real design or sourcing decision.
How does injection moulding cost per part change with quantity?
This worked example uses a 40 g part, 0 g runner, €1.50/kg resin, a 28-second cycle, four cavities, €32/hour machine time and €3,000 tooling. These are budget assumptions, not market averages or a Nordmould quotation.
Material costs €0.0600/part and machine time costs €0.0622/part. The calculator applies the 10% allowance to the entire subtotal, including allocated tooling. It is not a measured reject rate; VAT, setup, delivery and separately required work need additional assessment.
| Quantity | Tooling €/part | Total €/part | Calculation |
|---|---|---|---|
| 100 | 30.00 | 33.1344 | Open example |
| 1,000 | 3.00 | 3.4344 | Open example |
| 10,000 | 0.30 | 0.4644 | Open example |
| 100,000 | 0.03 | 0.1674 | Open example |
Allocating tooling over planned volume does not mean ordering every part immediately. For first-batch cash requirements, use the tooling payment terms and actual order quantity.

How to use the result
Watch which term dominates. Material and machine time rule at high volume — attack them with thinner walls (see the wall thickness guide) and more cavities. Mould amortisation rules at low volume — attack it with a simpler mould concept, fewer side actions (see undercuts) or family tooling. The cycle time guide shows why one millimetre of wall thickness can outweigh any machine upgrade.
Rates are illustrative budgeting assumptions, not a market price survey. Material grade, geometry, order size and quality requirements affect actual costs. This is a planning estimate, not a quotation.
