How to Calculate the Cost of Growing Microgreens

A tray can look beautiful and sell quickly while still producing little or no profit. To understand whether a microgreen variety supports the business, growers need to calculate the complete cost of producing, packaging, and delivering it.

Seed and media are only the beginning. Labor, utilities, packaging, labels, delivery, equipment, overhead, and crop loss all belong in the calculation. A cost matrix turns these expenses into information you can use for pricing and planning.

Define the Unit You Are Measuring

Begin with a standard production unit, usually one tray. Record the tray model and actual growing area because nominal sizes may vary.

Then define the selling unit, such as a two-ounce clamshell, larger retail package, restaurant bulk bag, or live tray. The connection between tray yield and finished packages allows you to calculate cost per sellable unit.

Use usable yield, not total material cut from the tray. Product lost during sorting, handling, packaging, or quality review cannot be counted as saleable inventory.

Calculate Seed Cost per Tray

Record the seed weight used in each tray and the actual delivered cost per pound or kilogram. Delivered cost includes product price, freight, duties, fees, and other acquisition expenses allocated appropriately.

Convert the units carefully. If seed costs $8 per pound and a tray uses 1.5 ounces, divide $8 by 16 ounces and multiply by 1.5. The seed cost for that tray would be $0.75.

Do not use one seed cost for every variety. Cilantro, radish, sunflower, pea, broccoli, amaranth, and beet can have very different prices and seeding amounts.

Add Growing Media and Tray Supplies

Measure how much soil mix, coco coir, matting, or other medium is used per tray. Divide the delivered cost of a bag, bale, brick, or roll by the number of trays it actually produces.

Include disposable liners and other single-use items. For reusable trays, calculate an estimated cost per cycle based on purchase price and realistic useful life, then include cleaning labor and supplies separately.

If breakage is common, add a replacement allowance rather than pretending every tray lasts indefinitely.

Measure Direct Labor

Labor is frequently underestimated because owners treat their own hours as free. Time soaking, seeding, moving, watering, inspecting, harvesting, packaging, cleaning, recording, and disposing of crop waste.

Multiply labor time by the full hourly labor cost, not only take-home pay. Depending on the business, this may include payroll taxes, workers’ compensation, benefits, and paid leave.

Batch tasks should be divided across the number of trays. If cleaning twenty trays takes one hour at a loaded labor rate of $20, cleaning labor is $1 per tray.

Allocate Utilities and Overhead

Electricity for lights, fans, pumps, heating, cooling, and dehumidification belongs in production cost. Water may be inexpensive per tray but should still be measured or reasonably allocated.

Overhead includes rent, insurance, software, bookkeeping, licenses, pest control, repairs, office expenses, and other costs that support production but are not tied to one tray.

Choose a consistent allocation method, such as cost per tray, square foot, rack, labor hour, or production week. No allocation is perfect, but ignoring overhead guarantees an incomplete number.

Include Packaging and Sales Costs

Add every clamshell, bag, label, absorbent pad if used, case, tape, and delivery container. Small items become significant at volume.

Sales-channel expenses also matter. Farmers markets may involve vendor fees, travel, tents, displays, samples, payment fees, and selling labor. Wholesale delivery includes fuel, vehicle expense, route time, totes, and invoicing. Online orders include boxes, packing material, labor, platform fees, and payment processing.

Calculate profitability by channel because the same package can produce a different margin at a farmers market, grocery store, restaurant, or direct subscription.

Account for Crop Loss and Unsold Product

If one tray out of twenty is typically lost, the nineteen successful trays must absorb the cost of the failed one. Include the seed, media, labor, utilities, and disposal associated with expected loss.

Unsold packages are also a cost. Track leftovers and markdowns by variety and sales channel. Reducing waste can improve profit without increasing sales.

Do not hide losses by averaging only successful weeks. Use a representative time period that includes normal operational problems.

Calculate Cost per Package

Add seed, media, tray allocation, labor, utilities, overhead, packaging, delivery, and expected loss to find the total cost per tray. Divide that total by the number of saleable packages produced.

For example, if a tray costs $18 in total and produces eight saleable packages, the base cost is $2.25 per package. Selling at $2.50 would leave only $0.25 before taxes, unexpected expenses, and desired profit. That price would likely be unsustainable.

Use the calculation to set a target margin, compare package sizes, and evaluate wholesale offers.

Compare Varieties by Contribution

A high-yield crop is not automatically the most profitable. It may require expensive seed, more labor, longer rack time, or a lower selling price. A lower-yield specialty variety may generate better return if customers pay a premium.

Compare profit per tray, per package, per rack space, and per production day. This reveals which crops deserve more capacity.

Keep the Matrix Current

Update costs when seed prices, freight, wages, packaging, rent, utilities, or yields change. Review the matrix at least on a regular schedule and before signing major contracts.

Use actual records rather than optimistic estimates. Your cost matrix should help answer practical questions: Which crop is most profitable? What is the lowest acceptable wholesale price? How much loss can the business absorb? Does a new package size improve margin?

Accurate costing gives growers permission to price with confidence. When every tray carries its true share of seed, labor, packaging, overhead, and risk, pricing becomes a business decision rather than a guess—and profitable growth becomes much easier to plan.
