How do you calculate molded toy part cost?

Multiply parts by cost per part and first-pass yield for the variable cost, then add fixed setup. In the default, 10,000 parts x $0.32 x 96% = $3,072 variable, plus $650 setup, for $3,722 total, or $0.3722 per part.

Why is cost per part higher than the raw cost per part?

Because the fixed $650 setup spreads across every part. At $0.32 raw, the per-part landed cost rises to $0.3722 once setup is amortized over 10,000 parts — the gap shrinks as volume grows.

How does first-pass yield affect the cost?

Yield scales the variable cost in this model — at 96%, the $3,200 gross variable cost becomes $3,072. Lower yield means more shots to hit your good-part target, so real programs should watch yield closely.

What is a good first-pass yield for injection-molded toy parts?

Mature toy molding often runs 97-99%+ first-pass yield on stable tooling; 96% as in the default is workable but leaves room to tighten. Cosmetic and multi-material parts tend to yield lower.

How do I lower cost per molded part?

Raise volume to dilute setup, add cavities to cut cost per shot, improve yield to reduce scrap, or reduce cycle time. Volume and cavitation usually move the number most on high-runner toys.

Does setup cost matter on a big run?

Less and less. On 10,000 parts the $650 setup adds about $0.052 per part; on 100,000 it's a tenth of that. Setup dominates only on short runs.

Toys, Sporting Goods & Recreational Products calculator

Molded toy part cost Calculator

Molded toy part costing rolls up the true cost of an injection-molded toy component: the variable cost per part scaled by yield, plus the fixed setup cost of getting the mold running. Toy and sporting-goods manufacturers use it to quote programs, compare cavities or resins, and decide whether a run's volume justifies the setup burden. Because setup is spread across every part, low-volume runs carry a heavier per-part burden than high-volume ones — a dynamic this calculator makes visible. Miss the yield or setup and you quote a part that loses money on every shot.

What this calculator does

Estimate molded toy part cost from run size, per-part molding cost, first-pass yield, and fixed mold setup adders for injection-molded toy components.
a toy manufacturer needs to cost an injection-molding run of plastic toy parts before quoting a retail program
It computes total molded-part cost and cost per good part from production volume, per-part cost, first-pass yield and a fixed setup adder.

Formula used

Total molded part cost = molded parts to produce x molded cost per part x first-pass yield + fixed mold setup cost
Cost per good part = total molded part cost / molded parts to produce

Inputs explained

Molded toy parts to produce:
Molding cost per part:
First-pass yield:
Fixed mold setup cost:

How to use the result

Use it when quoting an injection-molding program or comparing how volume, yield or setup affect the landed cost of a toy component.
It treats first-pass yield as a cost factor on good output; it doesn't separately price the scrap resin, regrind or rework that a low yield actually generates.
