# Manufacturing Yield in Woodworking: From Roundwood to Finished Product

How to chain sawing, drying, machining and finishing yields into one recovery figure, and convert it into roundwood purchases.

## Why 55% recovery is not a 55% business

Every wood product factory talks about recovery, but almost nobody sells at the sawmill exit. What ships is the product of every stage multiplied together: roundwood becomes lumber, lumber becomes dry parts, parts become machined components, components survive finishing and packing. Run [Manufacturing yield](https://nestingcalc.com/manufacturing-yield-calculator/) with realistic stage figures - 55% sawing, 70% drying, 85% machining, 95% finishing - and the chain yield is 31.09%. You buy 3.22 m³ of roundwood for every cubic metre that leaves the door.

## Stage one: primary breakdown

Converting logs into square-edged lumber is the bloodbath. Slabs, edgings, sawdust and log taper between them leave 40-60% as loss: FAO puts the global average recovery around 50%, EU softwood mills reach 48% and better, small Southeast Asian band mills manage 52% while chainsaw milling drops near 39%. Thin-kerf and twin-blade equipment, correct log sorting and measured overcut policies are where the points come back. See [Sawmill Recovery Rate: Benchmarks and How to Improve Yours](https://nestingcalc.com/guides/sawmill-recovery-rate/) for the recovery benchmarks in detail.

## Stage two: drying

Drying rarely loses volume outright - shrinkage from green to 12% moisture is single-digit percent - but it loses boards: checks, splits, warp and collapse downgrade or scrap material. A well-run kiln charge plans 5-15% degrade depending on species and thickness; refractory hardwoods cost more than spruce. The drying stage yield in [Manufacturing yield](https://nestingcalc.com/manufacturing-yield-calculator/) should reflect degrade, not just shrinkage, and [Kiln capacity](https://nestingcalc.com/kiln-capacity-calculator/) helps size the charge that keeps degrade low.

## Stages three and four: machining and finishing

Machining to final size typically yields 70-90%: cut-off strips, tenon and dado waste, planing allowance already removed in the rough-sizing stage. Finishing and assembly are gentler, 90-97%, but a colour reject at the last step costs the most because every previous stage's margin is buried in it. Track the stages separately - the loss table in [Manufacturing yield](https://nestingcalc.com/manufacturing-yield-calculator/) exists so you fix the biggest leak first, not the most visible one.

## Turning yield into purchasing maths

The practical output of a yield chain is the buy number. Divide the delivered volume by the chain yield: an order for 12 m³ of finished components at 31% chain yield commits you to roughly 38.6 m³ of roundwood. Feed the same numbers into [BOM cost](https://nestingcalc.com/bom-calculator/) with your log price and you have the material cost that decides whether the order is worth taking.
