Cost & Quoting

Cost Per Unit and Quoting in Meat, Poultry, and Seafood Processing

What actually drives cost per kilogram in protein processing, how to build a defensible quote, and the three errors that sink estimates.

In protein processing, material is the cost, not a line item you tune later. Live bird or primal purchase typically runs 70 to 85% of cost per finished kilogram, so a 1 percentage point yield miss dwarfs most labor savings. Build cost per unit as yield-adjusted material, plus direct labor, plus refrigeration and machine energy, plus packaging, plus scrap net of recovery, plus allocated overhead. The single most important move is dividing raw material cost by actual yield, not theoretical. At 2.20 dollars per live kg and 20% breast yield, breast material alone is 2.20 / 0.20 = 11.00 dollars per kg before anything else.

That yield division is where quotes quietly bleed. If you quote on a lab yield of 22% but the floor runs 20%, material cost is understated by 11 over 10, or 10%, enough to erase the whole margin on a commodity cut. Recover what you can: the Trim Value Recovery calculator credits fat, bone, and trim sold into rendering or pet food at 0.15 to 0.60 dollars per kg, which can offset 3 to 6% of material cost. Never book trim at full product value, and never assume 100% capture, since realistic capture is 85 to 95% of the trim generated.

Direct labor is the second driver, and deboning is the heaviest. A base rate of 18 to 22 dollars per hour, multiplied by a benefit and payroll burden of 1.30 to 1.40, lands near 25 to 30 dollars per productive hour. Use Deboning Labor to get operator hours per unit, then divide. If a line needs 13 deboners to run 40,000 birds and each bird yields 0.5 kg breast, that is 20,000 kg on 104 labor hours, so about 28 x 104 / 20,000 = 0.15 dollars per kg for deboning alone. Add evisceration, cut up, and packaging labor on top.

Refrigeration and machine time are smaller but real. Chilling, freezing, and cold storage run roughly 0.08 to 0.18 dollars per kg, driven by ammonia or CO2 compressor load and how hard the Chill Tunnel Capacity is pushed. The hidden cost is Sanitation Downtime. A plant that gives up 2.5 to 3 hours per day to cleaning runs productive time only 13 to 14 hours of a 16 hour window, so every fixed cost, rent, depreciation, salaried staff, spreads over fewer kilograms. Ignoring that dilution understates unit cost by 5 to 8% on lower volume days.

Packaging looks trivial until you total it. Film, trays, and labels run 0.08 to 0.20 dollars per retail pack, so use Packaging Film Usage to price the web precisely rather than guessing per pack. The costlier packaging error is overfill. Portion Giveaway Cost at 4% on 6 dollars per kg product is 0.24 dollars per kg of pure margin loss, often larger than the film itself. Estimators routinely forget that giveaway is material cost, not packaging, and it scales with every kilogram shipped. Quote to target weight and hold the line at 1.5 to 2% giveaway.

Overhead and losses close the model. Allocate plant overhead per productive kilogram, not per scheduled hour, or slow days look artificially cheap. Then subtract the quiet shrink: condemnation and inspection rejects of 0.3 to 1% of throughput, cold chain shrink and purge loss of 1 to 3%, and returns from Shelf-Life Risk failures. Each is material you paid for and cannot sell. A defensible quote itemizes these, while a weak one buries them in a single fudge factor and then loses money the moment volumes or yields drift from plan.

To build a quote you can defend, stack it in order: yield-adjusted material, minus trim recovery, plus each labor operation at loaded rate, plus energy per kilogram, plus packaging and giveaway, plus overhead per productive kilogram, plus a shrink allowance. Then add margin, usually 8 to 15% on commodity cuts and 20% or more on further processed or portioned items. The three estimates that most often blow up are theoretical instead of actual yield, forgetting that giveaway is material, and spreading fixed cost over scheduled rather than productive hours. Fix those three and cost per unit lands within 2 to 3% of actual.
