How do you calculate cabinet sheet metal yield?

Divide usable cabinet panels by total sheet metal panels processed, then multiply by 100. With 9,650 usable panels from 10,000 processed, yield is 96.5%.

What is a good sheet metal yield for appliance cabinets?

Mature, stamped white-goods cabinet lines typically run 96-99% panel yield. At 96.5% against a 98% target you are 1.5 points short, which on this 10,000-panel run is roughly 150 panels you expected to keep but lost.

What is the difference between yield and scrap rate?

They are complements: yield is good panels over total, scrap rate is rejected panels over total. A 96.5% yield equals a 3.5% scrap rate. Yield is the more intuitive KPI when you report sellable output.

Why is my cabinet yield below target?

The usual culprits are worn forming dies causing splits or wrinkles in the wrap, coil coating scratches, weld burn-through on cabinet seams, and dimensional drift that fails the fit check at assembly.

Does this account for material weight or sheet size?

No. This is a panel-count yield. If your scrap is concentrated in large door or wrap blanks, the dollar impact is worse than the percentage suggests, so review cost-weighted scrap alongside it.

How many panels did the 1.5-point gap cost?

On a 10,000-panel run, each missed point is about 100 panels, so the 1.5-point gap to your 98% target represents roughly 150 cabinet panels short of where you wanted to be.

Appliances, HVAC & White Goods Manufacturing calculator

Cabinet Sheet Metal Yield Calculator

Cabinet sheet metal yield measures how many wrap panels, side panels, and door blanks survive blanking, forming, and welding as sellable parts versus how many sheets you fed in. Appliance and HVAC fabrication managers track it because cabinet stock — coated steel, stainless, aluminized sheet — is one of the highest material spend lines on a white-goods BOM, and every scrapped panel carries the full cost of coil, coating, and press time. A yield drift of even one point on a high-volume refrigerator or range line translates into thousands of wasted blanks per week. Pairing the live yield against a target makes the gap visible before it shows up in the month-end scrap report.

What this calculator does

Calculate good cabinet sheet metal yield from usable panels, total panels processed, and the target yield.
a manufacturing or quality engineer needs to measure sheet metal panel yield for appliance or HVAC cabinets
It computes the percentage of sheet metal panels that exit the line as usable cabinet parts and the point gap to your target yield.

Formula used

Cabinet sheet metal yield = usable cabinet panels ÷ total sheet metal panels processed × 100
Yield gap to target = cabinet sheet metal yield - target cabinet sheet metal yield

Inputs explained

Usable cabinet panels:
Total sheet metal panels processed:
Target cabinet sheet metal yield:

How to use the result

Use it at end of shift, per part number, or after a die change to confirm the press and forming cells are converting blanks to good panels at the expected rate.
It is a count-based yield and does not weight a scrapped door blank differently from a small bracket, so blend it with cost-weighted scrap data when defect mix varies.

Current U.S. benchmarks

Industrial electricity averages 8.66 cents per kWh across the U.S. (EIA, Apr 2026), up 5.5% from a year earlier. Energy-intensive steps carry this directly into unit cost.
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).
