Production capacity calculator

Estimate good units per shift and running time for an order from cycle time, downtime, parallel stations and yield. Expected output may be fractional because yield is an average.

How it works

Formula

$Available time per station = 60 \times Shift length - Breaks and downtime per station$
$Expected good units per shift = \frac{\frac{Available time per station \times 60}{Seconds per unit per station} \times Identical parallel stations \times Good-output yield}{100}$

Assumptions and limitations

Stations are identical and independent, with constant cycles and yield. The order time is running time only. Excludes queueing, setup changes, shared bottlenecks and statistical quality guarantees.

How to use this tool

Set up the inputs

Enter shift hours and downtime for each station. Add measured seconds per unit, the number of parallel stations, expected good yield and order quantity.

Worked examples

Check what one shift can produce

(8 × 60 − 60) × 60 / 45 × 0.95 = 532; 500 / (60 / 45 × 0.95) ≈ 394.7368 min.

Frequently asked questions

How should I read the result from Production capacity calculator?

Expected output may be fractional because yield is an average. The integer result rounds down; actual production can vary. Compare order running time with the available shift time.

Processing and privacy

The calculation or transformation runs in your browser. The tool does not send its input values or generated output to an application server. Loading a page still makes infrastructure requests; optional analytics and Google consent messages have separate controls.
