Why can availability and first-pass yield not exceed 100 percent?

Both are shares of the gross units the booth can run. A value above 100 would claim more uptime or more first-pass parts than the cycle count allows.

What is the difference between the two loss rows?

Downtime loss counts units never sprayed because the booth was unavailable. Rework loss counts parts sprayed but failed at first-pass inspection, so they need a second cycle.

Where should I attack a capacity shortfall first?

Compare the two loss rows. Downtime usually removes more units than rework, so returning the booth to service pays back faster than a finish quality program.

Does rework reduce the good capacity twice?

No. First-pass yield removes failed parts once, and availability removes cycles once. A part that passes on its second cycle still counts in that cycle's parts per cycle.

Finish Booth Capacity Calculator

Estimate the good units a finish booth delivers from parts per cycle, available cycles, booth availability and first-pass finish yield. The page sets that capacity against the good units the schedule needs.

What this calculator does

Good finish-booth capacity from parts per cycle, cycles, availability and first-pass yield, checked against a unit target.

Formula used

Gross capacity = parts per cycle × available cycles
Good capacity = gross capacity × availability ÷ 100 × first-pass yield ÷ 100
Downtime loss = gross capacity × (100 − availability) ÷ 100
Rework loss = gross capacity × availability ÷ 100 × (100 − yield) ÷ 100
Margin to target = good capacity − target good units

Inputs explained

Parts per Booth Cycle: Parts loaded on the booth rack each cycle.
Available Booth Cycles: Cycles the booth can run in the period.
Booth Availability: Measured booth uptime share from the OEE log.
First-Pass Finish Yield: Parts passing finish inspection without rework.
Target Good Units: Good units the finishing schedule needs.

How to use the result

Best suited to scheduling a finishing shift, checking finishing against a ship date, quantifying booth downtime loss.
Capacity only; drying, cure and handling time between cycles are not scheduled here. The model assumes one finish line; a shared booth splits these cycles across jobs.

Current U.S. benchmarks

The producer price index for lumber stands at 286.633 (BLS, Aug 2026), up 7.6% 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).
