How do you calculate good crew capacity?

Multiply parts per cycle by available cycles to get gross capacity, then multiply by uptime and first-pass yield. With 4 units/cycle, 480 cycles, 90% uptime and 97% yield: 4 × 480 × 0.90 × 0.97 = 1,676 good units.

What's the difference between gross and good capacity?

Gross capacity is the theoretical ceiling — 1,920 units here (4 × 480). Good capacity is what survives downtime and scrap — 1,676 units. The 244-unit gap is the crew's real loss to plan around.

How much output does downtime cost the crew?

At 90% uptime the crew loses 192 units to stoppages in this example — the difference between the 1,920 gross and the 1,728 that would run if only downtime applied.

How much does yield cost the crew?

First-pass yield of 97% scraps roughly 52 units here, on top of the downtime loss. Small yield gaps matter: three points of scrap on a 1,728-unit base is real money.

How do I use this to size a crew?

Divide your demand target by good capacity per crew. If you need 3,350 good units and one crew delivers 1,676, you need two crews — one alone falls short even before variability.

What is a good first-pass yield?

It's process-dependent, but 95%+ is a common floor for mature manual assembly and 99%+ for well-controlled machining. The 97% here is respectable but still costs ~52 units per window.

Workforce, Labor Standards & Skills Planning calculator

Crew Size Calculator

The crew size calculator translates a crew's per-cycle output into the number of good, sellable units it can actually deliver in a shift or window after downtime and scrap. Production supervisors and industrial engineers use it to right-size staffing against a demand target and to check whether a cell can hit its schedule. It matters because staffing to gross capacity ignores the two losses that always show up on the floor — the line stops, and not every part passes the first time.

What this calculator does

Estimate crew size for workforce, labor standards and skills planning using production-ready inputs so teams can confirm whether capacity can cover demand before committing the schedule.
Use it when crew size in workforce, labor standards and skills planning is being asked to take on more work and you need to know if there is room.
It computes gross crew capacity from output per cycle and available cycles, then multiplies by uptime and first-pass yield to give good (sellable) capacity.

Formula used

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

Inputs explained

Parts produced per cycle by the crew:
Available production cycles in the window:
Expected uptime (availability):
Expected first-pass yield:

How to use the result

Use it when planning crew staffing for a production window, validating a schedule against realistic capacity, or quantifying downtime and yield losses.
It applies uptime and yield as flat averages; a crew that runs steadily differs from one with big startup scrap or a mid-shift breakdown even at the same averages, so use realistic loss numbers, not nameplate.

Current U.S. benchmarks

Manufacturing hourly earnings average $30.27 (BLS, Jun 2026), up 4.4% from a year earlier. Median machinist pay is $28.24/hr (OEWS 2025), with state medians on each state page. Manufacturers have 529k open positions nationally (BLS JOLTS).
