MSU Unit Economics
The pattern across sources. An inspected mobile unit is a high-fixed-cost asset that sits idle most of the week. Labor and capital recovery are spread over too few head. The surviving units either had their capital donated, or sat inside an existing butcher business that absorbed the overhead.
Every figure below is for a USDA-inspected unit unless marked otherwise, and carries the year its source reported. For the far cheaper custom-exempt rig, see Custom-Exempt Mobile Rig.
Capex over time
| Year | Item | Cost | Source |
|---|---|---|---|
| 2000 | IGFC total project (trailer $60k, equipment $27k, truck $18k, design $25k, testing $15k, outreach $5k) | $150,000 | IGFC |
| 2007 | Two MSUs (Nevada study, never built) | $413,650 (~$207k each) | Nevada |
| 2008 | Replacement IGFC trailer, same capacity | $170,000 | IGFC |
| 2009 | MSU $250k + used truck $20k + corrals/knock box $10k | $280,000 | Idaho calculator |
| 2009 | PSMPC 45-ft TriVan trailer; total start-up ~$500k | $250,000 trailer | PSMPC |
| 2011 | Start-up excluding cut-and-wrap (MSU $200k, used tractor $26k, misc.) | $235,310 | NMPAN 2011 guide |
| 2022 | Turnkey Friesla build-out + ~$280k operating capital if financed | ~$550,000 | Rusted Gate |
| 2026 | Sentinel USDA-compliant 30 ft gooseneck / 53 ft semi, list price | $192,000 / $300,000 | Sentinel |
| 2026 | Sentinel custom-exempt 12 ft / 16×8 / 16×10, list price | $72,000 / $92,000 / $115,000 | Sentinel |
Builders named: Friesla (Everson WA, turnkey), Mobile Processing Trailers & Supply (Colorado, “bare bones”; Rusted Gate calls the cost difference “significant”), TriVan, and Sentinel (Idaho Falls; 2026 list prices above).
The trailer is often not the biggest capital item. In the 2007 Nevada design, the fixed chill/age/cut plant was costed at $1.51M, later revised to about $0.8M for the building. That is 4–7× one MSU. See The Fixed-Facility Dependency.
Throughput ceiling
| Source | Beef per kill day | Kill days per week | Crew |
|---|---|---|---|
| Idaho calculator (2009) | max 14 (2/hr × 7 hr) | max 4–5 | 3 butchers + 2 assistants |
| IGFC (2007–08, actual) | 9–10 | 3–4 | 2 butchers, 8 hr + 2 hr driving |
| PSMPC (2011–13, actual) | 8–10 animal units | ~90 days/yr (2012 est.) | 1 contract butcher + own assistants |
| Coast Grown (2009, actual) | ~3.6 (32 head in 9 days) | — | — |
| Rusted Gate (2022, plan) | — | 1–2 in years 1–2 | 2 butchers at 0.5 FTE |
A kill day is capped by the hours under inspection (about 8) plus set-up, driving and clean-up. Days per week are capped by hauling carcasses back, washing and maintenance. Real units ran at a fraction of the theoretical ceiling.
Kill fees (beef, $/head)
| Year | Who | Fee | Notes |
|---|---|---|---|
| 2008 | IGFC (WA MSU) | $105 | Plus $0.82/lb cutting; $450 minimum per farm visit; first rates “too low”, losing money within 6 months |
| 2011–13 | PSMPC (WA MSU) | $110 member / $140 non-member | Surcharge for cattle >30 months |
| 2022 | Oregon fixed USDA plants | $80–$205, avg $134 | Cut-and-wrap $1.00–$1.50/lb |
| 2022 | West Coast MSUs | $159 (IGFC non-member) – $260 (Bay Area) | Heritage Meats $216 |
| 2022 | Rusted Gate break-even | $240 by year 3 | Only with grant-funded capital |
| 2026 | Blue Ridge Meats, Middletown VA | not published | Books 3–5 months out; bills on hot weight |
| 2025 | T&E Meats, Harrisonburg VA (USDA + custom, fixed) | $75 | + $1.05/lb standard cut and pack; +$0.10/lb resale label; +$50 for cattle >30 months |
| 2026 | Seven Hills, Lynchburg VA (USDA, fixed) | none | $1.20–$1.30/lb carcass weight, all-in; $775 minimum |
Virginia benchmark (round 2): about $1.15–1.30/lb hanging weight all-in at inspected Valley plants (2025–26). Fixed-plant kill fees are low ($75), so plants earn their money on cutting. See Valley Processor Landscape.
Break-even: the Rusted Gate table (2022, USDA-inspected)
| Scenario | Y1 | Y2 | Y3 |
|---|---|---|---|
| 80% debt, $175/hd | −$57,099 | −$28,739 | −$79,227 |
| Grant-funded capital, $175/hd | −$40,328 | −$12,563 | −$62,456 |
| Grant capital + fee $200 → $240/hd | −$27,828 | +$17,310 | +$2,544 |
Volume was 500 / 700 / 1,000 head. Year 3 losses jump because both butchers go full-time. The plan’s own conclusion: “The MSU will likely not be profitable for many years, if ever”. It needed a subsidy of “$25-50K plus a year”. Three agents extracted this plan independently and agree on every figure.
What drives cost
- Labor. About 75% of total cost at IGFC (2008). It is Rusted Gate’s largest line, followed by depreciation, interest and offal disposal. Skilled cutters take about 2 years to train, and part-time butcher jobs are “difficult to find” people for.
- Rough labor cost per head [inferred from the 2009 Idaho figures]: a 5-person, 7-hour crew costs about $860 per kill day, or about $61/head at 14 head/day before capital. At 4 head/day it is about $215/head.
- Capital recovery per head [inferred, Idaho 2009]: about $43k/yr in loan payments ÷ 300 head ≈ $143/head. Utilization is the lever that brings this down.
- Distance. IGFC caps its service area at 100 miles (1–2 hours), “the largest area the MPU can serve efficiently”. Nevada budgeted fuel and repairs at $230/day for two units covering 150 miles/day at 5 mpg.
Why the optimistic projections differ
The NMPAN 2011 pro forma showed profit from year 1 ($36k in 2011 rising to $131k in 2014). It assumes 260 full kill days a year from launch, with marketing, rent, benefits and admin carried by a partner cut-and-wrap. The Idaho calculator’s $280k “return” is a retail margin on meat the operator owns, not fee-for-service profit. Never quote either as evidence that a fee-for-service MSU pays.
A fixed-plant benchmark (ERS ERR-150, 2013)
The USDA research report modeled annual expenses at $231k for a very small plant (4 FTE), breaking even at about 462 beef a year (about 9 a week). A small plant (10 FTE) costs $565k and needs about 1,130 beef; a regional plant costs $4.44M and needs about 8,884. All three assume $500 processing revenue per beef. Its mobile-unit box warns that MSUs may cost more per head to run (fuel, maintenance, transit, limited capacity), and that kill plus a separate cut-and-wrap can cost more in total than one plant. Its success factors are a committed cut-and-wrap partner, one or two dedicated leaders, and the right scale (ERR-150). Figures are in 2013 dollars.
How the survivors made it work
- IGFC. Capital came from grants and donations, so there was no initial debt. 30 founding members paid $600 each. Members had no other slaughter option. Fees were raised repeatedly.
- PSMPC. A conservation district owned the unit and carried the loan, leasing it to the co-op for $1/yr. The co-op switched from about 6 paid staff to one contract butcher at $300/day plus a per-animal fee, who folded the unit into his existing business. It still closed by January 2021, and the unit now sits parked at one plant.
Gaps
Custom-exempt rig costPartly resolved: $72k–$115k list (Sentinel). There is still no full operating budget for a custom-exempt mobile business.- Prices for Gentle Harvest, Gore’s and Crabill’s, and any farm-call fee charged by a Mid-Atlantic mobile operator.
