How do you calculate net production capacity?

Multiply units per cycle by cycles per shift for gross capacity, then multiply by uptime and first-pass yield. Here 1 x 16 = 16 gross, derated by 88% uptime and 95% yield, gives 13.376 net good units per shift.

What is the difference between gross and net capacity?

Gross capacity is the theoretical maximum if nothing went wrong — 16 units in the example. Net capacity subtracts real losses: about 1.92 units lost to downtime and 0.7 to inspection rejects, leaving 13.376 sellable units.

What is a good first-pass yield for clinical furniture assembly?

High-performing assembly lines aim for first-pass yield in the high 90s. The 95% in the example still costs roughly 0.7 units a shift, so even small yield gains add up across a year of production.

How does uptime affect capacity?

Uptime scales gross capacity directly — every point of downtime is a proportional point of lost output. At 88% uptime the line forfeits about 1.92 units per shift before quality losses even enter the picture.

How do I close the capacity gap?

Attack whichever loss is larger. In the example downtime (1.92 units) costs more than rejects (0.7), so reducing changeover and jam time would recover more capacity than chasing the last points of yield.

Can I use this for multiple product variants on one line?

Run it per variant, since units per cycle and yield differ between a basic exam table and a powered ICU bed, then sum the net figures for a realistic mixed-shift plan.

Hospital Equipment & Clinical Furniture calculator

Capacity Gap Calculator

Capacity gap analysis shows a hospital-equipment manufacturer the real, sellable output of an assembly line after downtime and quality losses, not the optimistic number on the standard. Production managers and schedulers use it to see the gap between gross capacity and net good units per shift so they commit to delivery dates they can actually hit. On a clinical-furniture line building beds, stretchers and exam tables, both unplanned downtime and final-inspection rejects quietly erode throughput, and pretending they don't exist is how you miss a hospital's installation window. The model takes units per cycle and cycles per shift to get gross capacity, then derates it by line uptime and first-pass yield to reveal what really ships.

What this calculator does

Estimate the good units per shift your hospital equipment production line can deliver, accounting for assembly cell output, available cycles, line uptime, and final inspection first-pass yield.
Use it when a new hospital equipment order is being loaded to the production schedule and you need to confirm whether the line can meet the shipment commitment without overtime or additional headcount.
It computes net good units per shift by multiplying gross capacity by line uptime and final-inspection first-pass yield.

Formula used

Gross production capacity = units per cycle × available cycles per shift
Net good units per shift = gross capacity × line uptime × first-pass yield

Inputs explained

Hospital equipment units completed per assembly cycle:
Available assembly cycles per shift:
Assembly line uptime:
Final inspection first-pass yield:

How to use the result

Use it for shift-level capacity planning, delivery-date commitments, and finding where downtime or rejects are eating throughput.
It assumes uptime and yield are independent and stable; a real line where a jam also causes quality defects, or where yield drifts during a run, will behave worse than the single-point estimate.

Current U.S. benchmarks

The producer price index for lumber and wood products stands at 280.994 (BLS, May 2026), up 4.2% from a year earlier. Quotes priced off last quarter's material cost miss this move.
U.S. manufacturing runs at 75.6% of capacity with new factory orders at $657B per month (Federal Reserve and Census, May 2026).
Steel mill PPI stands at 348.53 (BLS, May 2026), up 6.7% from a year earlier. New factory orders are up 2.3% year over year (Census).
The U.S. has 14,378 furniture and related products establishments employing about 355,594 workers (Census County Business Patterns, 2023).
