Cost and Quoting

Cost Per Pound in Indoor Farming: Building a Defensible Quote

A money-first breakdown of what actually drives cost per pound in indoor farming and packhouses, and how to quote it without losing your margin.

Build every quote as cost per saleable unit, not cost per plant started. The five big buckets are energy, labor, water and nutrients, facility overhead, and losses. For a typical leafy green vertical farm, energy runs 25 to 40 percent of cash cost, labor 30 to 45 percent, consumables 8 to 15 percent, and overhead the rest. If your fully loaded cost lands at 3.20 dollars per pound and you sell at 4.50, that 1.30 gross covers packaging, freight, and shrink before any profit. Miss one bucket and the quote is fiction.

Energy is the bucket estimators most often understate. Pull fixture and HVAC draw from the Grow Light Energy Cost and Climate Control Load tools, then price the full connected load, not the nameplate. A room pulling 37,000 kWh per month for lighting typically adds 40 to 60 percent again for cooling and dehumidification, so 55,000 kWh total at 0.11 dollars is about 6,050 dollars monthly. Spread across 4,000 pounds of monthly output that is 1.51 dollars per pound of energy alone. Demand charges on peak kW can add another 0.20 to 0.40 per pound in high-tariff regions.

Labor is where quotes quietly bleed. Use the Harvest Labor Forecast to convert crop volume into hours: if a picker processes 40 pounds per hour and fully burdened wages are 22 dollars per hour, harvest labor is 0.55 dollars per pound before transplanting, seeding, and sanitation. Those indirect tasks usually add 60 to 90 percent on top, pushing total labor near 0.95 dollars per pound. Estimators who quote only the harvest line understate labor by roughly a third, which is often the entire difference between a winning bid and a profitable one.

Consumables and water are smaller but easy to get wrong. Price nutrients from Nutrient Mix Consumption and irrigation from Water Use per Crop, then add substrate, seed or transplants, and packaging. Seed and plugs alone can run 0.30 to 0.60 dollars per head for grafted or specialty varieties. Packaging, the clamshell and label, frequently exceeds the raw crop cost at 0.25 to 0.45 dollars per unit. Water is cheap at a few cents, but nutrient concentrate and CO2 enrichment together commonly reach 0.15 to 0.25 dollars per pound, so do not round them to zero.

Losses are a cost, not a footnote. Feed your grade-out into the Rejection Rate Cost tool: every unit scrapped after full growing carries all upstream cost. At 3.20 dollars per pound of cash cost, a 12 percent rejection rate does not cost you 12 percent of nothing, it adds about 0.44 dollars to each good pound you actually sell, because the survivors must absorb the dead. Cutting rejects from 12 to 6 percent is worth roughly 0.20 dollars per saleable pound, often a faster margin gain than chasing a cheaper energy contract.

For packhouse and agri-processing quotes, throughput and cold storage set the overhead rate. Run Packhouse Throughput to get units per line hour, then divide fixed line cost by that rate. A line costing 480 dollars per hour to staff and run at 3,200 units per hour is 0.15 dollars per unit, but the same line at 2,100 units, its real average with changeovers and jams, is 0.23 dollars. Cold Storage Utilization matters too: a room at 55 percent occupancy charges the same rent per pallet position as one at 90 percent, so poor utilization can double storage cost per case.

Quote defensively by separating fixed from variable and stating volume assumptions in writing. Fixed costs, rent, base energy, and salaried staff, must be spread over an honest volume, so a quote priced at 4,000 pounds per month collapses if you only ship 2,800. Add a contingency of 5 to 8 percent for shrink, energy tariff swings, and yield variance, and revisit pricing whenever any single input moves more than 10 percent. The most common quoting failure is not a math error, it is loading fixed cost over an optimistic volume that the facility never actually hits.
