Furniture manufacturing cost: three materials, three different units
Costing a cabinet or a chair across all ten categories. The catch is that panels, edging and hardware are each bought in a different unit, and mixing them up quietly breaks the material line.
Most trades buy their main material in one unit. Furniture buys it in three, and that is where the costing usually goes wrong before it has started.
| Material | Bought by | Consumed by |
|---|---|---|
| Panels and sheet goods | The sheet | Area of parts, plus the offcut around them |
| Edge banding, moldings, rails | The linear meter or foot | Total edge length on the part |
| Hardware — hinges, slides, fasteners | The piece or the set | Count on one finished product |
The ten categories, in production order
1. Material — panels, edging, hardware
Panels are charged by **sheets consumed**, not by the area of the parts. The offcut around the parts was bought with the sheet and it does not disappear. Panel yield has its own guide because it decides more money faster than anything else in this trade.
Edging and moldings by total length including the trim loss at each end. Hardware counted on one finished product — this is tedious once per model and then done.
2. Machine time
Panel saw or beam saw, edgebander, CNC router, drilling, sanding, spray line. Different rates per machine, converted to per part by the run they actually occupy.
The finishing line is the one shops forget to rate properly. It is often the slowest step and the one that constrains everything else, which makes its rate more consequential than it looks.
3. Labor
Keep assembly separate from machining. A flat-packed product ships without assembly labor and an assembled one does not — same product, materially different cost, and the sheet should be able to show it.
4. Tooling
Saw blades, router bits, sanding belts, drill bits, edgebander glue. Cost divided by parts produced between changes. Abrasives are the item most often written off as shop supplies and they are rarely small.
5. Scrap
Panels cut wrong, parts damaged in handling, finishing rejects. A part scrapped after finishing has consumed panel, machining, edging and finish — value it at the stage it was lost, not at material price.
6. Rework
Sanding back and refinishing, re-edging, filling. If your shop scraps rather than reworks, enter zero rather than leaving it blank.
7. Outside processing
Laminating, veneering, spraying, upholstery, glass and mirror, metal frames. Vendor price per lot divided by pieces, plus transport both ways — and furniture components are bulky, so that transport is not a rounding error.
8. Packaging
Cartons, corner protectors, film, foam, fittings bags, assembly instructions. Packaging is a large line in this trade because the product is big and damages easily, and it is the wrong place to economize without measuring.
9. Freight
Charged by **space, not weight** — the trailer fills before it loads up. This changes what an improvement is worth, so it has its own guide.
10. Plant overhead
Space, dust extraction, compressed air, spray booth ventilation, supervision. Furniture plants use a lot of floor area per unit of output, so space is usually the dominant component here.
Three checks
- Panels, edging and hardware are three separate lines in three different units.
- Panel cost is sheets consumed, not part area.
- Assembly labor is separated from machining labor, so a flat-pack option can be costed.
