Cost of Production per Acre and per Unit

What is cost of production?

It is the total cost of growing a crop or raising livestock, expressed per acre or per unit sold: bushel, ton, pound, head or dozen. Per acre helps with planning and rental decisions. Per unit helps with pricing and marketing.

Extension budgets, such as those from Iowa State and Penn State, show the typical way to organize costs. Use them as templates, then replace the figures with your own.

Consider building your cost of production in two versions: a cash version that shows what you actually pay out, and a full version that adds depreciation, labor and a land charge. The cash version tells you whether you can pay the bills. The full version tells you whether the farm is sustainable over time.

Which costs should you include?

Direct costs such as seed, fertilizer, chemicals, feed, vet, fuel, hired labor, crop insurance and interest on operating money. Then overhead and fixed costs: machinery depreciation, building costs, property taxes, insurance and land cost, whether you pay rent or own.

Many farmers leave out their own labor and the cost of owned land. That makes the farm look more profitable than it is. Include a fair value for both, or at least show them separately.

• Fixed and overhead costs
• Operator labor and land charge

How do you calculate it per acre?

Add the costs for one field or crop and divide by the acres. Use actual receipts and invoices where you can. For shared costs such as machinery, allocate fairly by use or hours.

Do it field by field if costs differ, since rented ground and owned ground rarely cost the same.

Record keeping is what makes this possible. Use farm accounting software or a simple spreadsheet that tracks costs by field or enterprise, and code each expense when you enter it. Sorting costs at year end from a shoebox of receipts is slow and leads to guesses.

How do you calculate it per unit?

Divide total cost by the units produced, not the units planned. A poor yield raises cost per bushel even when cost per acre stays the same. For livestock, divide by pounds sold or by head, depending on the enterprise.

Compare your per-unit cost with the price you can expect. The gap tells you whether you have a margin.

For livestock, include the cost of keeping the breeding herd or flock, not just the animals sold. The cost of producing one calf includes the cow's feed, health, labor and depreciation for the whole year, spread over the calves actually weaned, which makes weaning rate a major driver of unit cost.

Where do you find reference figures?

USDA ERS publishes commodity costs and returns data, and land-grant universities publish crop budgets for their regions. Use them to spot costs that look out of line, not to replace your own records.

Check the year of any budget you use, since input prices move.

Share your cost of production with your landlord when you talk about rent, and with your lender when you talk about credit. A clear number, with the reasons behind it, makes the conversation about facts instead of opinions. It also gives you a basis to say no to a price or rent that will not work.

How do you use the number?

Use it to set a floor price, compare crops, decide how much rent you can pay and show a lender that you know your margin. It also helps you see which inputs matter most to your bottom line.

Revisit the number each season. A figure from three years ago will not reflect today's costs.

For vegetables and specialty crops, count labor carefully, including harvest, washing, packing and selling time. Many small farms find that labor is the largest cost per unit, and that tracking hours for a few weeks gives a better estimate than guessing.

What mistakes are common?

Leaving out labor, depreciation or interest, using planned yield instead of actual, and spreading shared costs unevenly. Another is comparing your full cost with a neighbor's cash cost.

Be clear about whether a figure is full cost or cash cost, and keep the two apart.

A helpful exercise is to rank your costs from largest to smallest. Most farms find that three or four lines make up most of the total. Those lines deserve the most attention, whether that means testing soil before buying fertilizer, comparing feed sources or reviewing machinery use. Small savings on small lines rarely matter as much as a modest improvement on a big one.
