How do you calculate tooling capacity?

Multiply parts per cycle by the available cycles in the period for gross capacity, then multiply by availability and first-pass yield. With 4 parts/cycle over 480 cycles at 90% availability and 97% yield, good capacity is 4 x 480 x 0.90 x 0.97 = 1,676 good parts.

What is the difference between gross and good tooling capacity?

Gross capacity assumes every cycle runs and every part passes — 1,920 parts here. Good capacity subtracts 192 parts lost to downtime and 51.8 to yield, leaving 1,676 you can actually ship. Plan releases against the good figure, not the gross.

How do I know if I need a second tool?

Compare good capacity against forecast demand for the period. If demand exceeds the 1,676 good parts a single tool delivers, you either add cycles (more shifts), lift availability and yield, or build a second tool — this calculator shows which lever closes the gap.

What is a good tooling availability figure?

90% is a solid target for a maintained tool on a dedicated machine; shared machines and frequent changeovers pull it lower. The 192-part downtime loss in the example is what that 10% of unavailable cycles costs you in shippable parts.

Does first-pass yield really affect capacity that much?

Yes — every scrapped part consumes a cycle you cannot reuse. At 97% yield you lose 51.8 parts over the period; drop to 90% yield and the loss more than triples, which can be the difference between covering a release and coming up short.

How is tooling capacity different from OEE?

OEE blends availability, performance and quality into one machine score. Tooling capacity applies availability and quality (yield) to a specific tool's cycle budget to answer a planning question — how many good parts can this tool make this period — rather than rating machine effectiveness.

Tooling, Fixtures, Dies & Mold Economics calculator

Tooling Capacity Calculator

Tooling Capacity tells you how many good parts a die, mold or fixture can produce over a planning period once you account for the cycles lost to downtime and the parts lost to scrap. Production planners, capacity engineers and schedulers use it to check whether a tool can cover a customer release, decide if a second tool is needed, and set realistic ship commitments. It matters because scheduling off theoretical cycle counts overstates what the floor can deliver — the gap between gross and good capacity is exactly where late shipments come from. This calculator gives you the shippable number to plan against.

What this calculator does

Estimate tooling capacity for tooling, fixtures, dies and mold economics using production-ready inputs so teams can confirm whether capacity can cover demand before committing the schedule.
Use it when tooling capacity in tooling, fixtures, dies and mold economics is being asked to take on more work and you need to know if there is room.
It converts parts-per-cycle and available cycles in the period into good-part capacity by derating for tooling availability and first-pass yield.

Formula used

Gross tooling capacity = tooling capacity output per cycle × available tooling capacity cycles
Good tooling capacity = gross capacity × expected tooling capacity uptime × expected tooling capacity first-pass yield

Inputs explained

Parts per tooling cycle:
Available tooling cycles in period:
Tooling availability (uptime):
Tooling first-pass yield:

How to use the result

Use it during capacity planning, order acceptance, or when deciding whether existing tooling can cover forecast demand or a second tool is required.
It uses period-average availability and yield; it does not model peak-demand bottlenecks, changeover time between jobs, or a single tool shared across multiple part numbers.

Current U.S. benchmarks

The producer price index for plastic resins and materials stands at 319.371 (BLS, May 2026), up 19.5% 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).
