How do you calculate rework cost?

Multiply units produced by the per-unit rework cost and by the rework rate (as a decimal) to get variable cost, then add fixed rework-area overhead. With 250 units, $85/unit, a 6% rework rate and $300 overhead, that is 250 x 85 x 0.06 = $1,275 variable plus $300 fixed = $1,575 total.

What is a good rework rate for medical equipment?

World-class regulated assembly targets under 1-2%. The 6% default here is high for finished hospital equipment and would prompt a corrective-action investigation into the dominant defect mode.

Why include fixed rework overhead?

A dedicated rework cell, bench, tooling and inspector time cost money even in a clean period. Including the $300 fixed overhead keeps you from understating cost of poor quality when volumes are low.

What does rework cost per unit produced mean?

It spreads total rework cost across every good and bad unit built. Here $1,575 over 250 units is $6.30 per unit produced, a useful figure to load into standard cost or a quote.

Rework cost vs scrap cost?

Rework recovers a unit through extra labor and parts; scrap writes it off entirely. Rework is cheaper per event but consumes capacity and documentation effort, so chronic rework can cost more than occasional scrap.

How do I lower rework cost on clinical furniture?

Attack the rework rate first, since it scales the whole variable term. Reducing 6% to 3% halves the $1,275 variable cost. Target the top defect mode (often weld porosity, paint finish or hardware torque).

Hospital Equipment & Clinical Furniture calculator

Rework Cost Calculator

Rework Cost tells a clinical furniture or medical equipment plant how much money is being burned re-doing work that should have been right the first time. It rolls the variable cost of fixing defective units, the fraction of the build that fails inspection, and the fixed cost of staffing a rework cell into one period dollar figure. Quality engineers and plant controllers use it to size the true cost of poor quality on regulated products like hospital beds, overbed tables and exam stretchers, where a missed weld or a non-conforming caster can mean a returned unit and a field complaint. Because medical-device rework usually triggers documentation and re-inspection, the per-unit cost is rarely trivial, so the metric quickly justifies investment in first-pass quality.

What this calculator does

Estimate total rework cost for a hospital equipment or clinical furniture production period using total units produced, average rework cost per unit when reworked, the rework rate, and fixed rework area overhead.
Use it when calculating the cost impact of rework on a hospital bed or clinical furniture product line, or when building the business case for reducing inspection rejects.
It computes the total cost of reworking non-conforming hospital equipment or clinical furniture in a period by adding variable rework cost to fixed rework-cell overhead.

Formula used

Variable rework cost = total units produced × rework cost per unit × (rework rate / 100)
Total rework cost = variable rework cost + fixed rework area overhead

Inputs explained

Hospital beds or clinical units built this period:
Cost to rework one unit (labor, parts, re-test):
Share of units requiring rework:
Fixed rework cell overhead per period:

How to use the result

Use it monthly or per production run to quantify cost of poor quality and to build the business case for process or supplier corrective actions.
It assumes one average rework cost per unit; a few high-severity teardowns (e.g., a frame re-weld) can cost far more than a cosmetic touch-up and skew the real number.

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).
