Cost of Production: The Most Important Number on Your Farm

What does it cost you to produce a bushel of corn, a hundred pounds of milk, or a pound of mushrooms? It may sound like a simple question, but the answer is one of the most valuable pieces of information a farmer can have. Knowing your cost of production helps you understand where your farm is making money, where costs are getting out of hand, and how to improve marketing decisions.

Calculating your cost of production takes some time, but it doesn’t have to be complicated. Each enterprise, or commodity, will have its own cost of production. The first step is to total all the expenses required to produce each product. For livestock, that includes costs such as feed, breeding, veterinary care, bedding, and supplies. For crops, expenses may include seed, fertilizer, chemicals, and fuel. Don’t forget to account for overhead expenses, such as insurance, utilities, taxes, and depreciation. While depreciation isn’t a cash expense, it reflects the wear and tear on your assets and is an important part of the true cost of production.

Many farms have multiple enterprises and produce a range of products, including dairy, grains, forages, vegetables, and others. In those cases, expenses need to be assigned to the appropriate enterprise. Some costs are easy to assign. For example, milk hauling charges belong to the dairy enterprise, while mushroom packaging costs belong to mushroom production. Other expenses, such as fuel, machinery repairs, insurance, and utilities, are incurred across multiple enterprises on the farm. These costs should be divided among enterprises using a method that makes sense for your operation, such as acreage, labor hours, or another reasonable measure. Good recordkeeping makes this process much easier and leads to more accurate results.

Once you’ve totaled the expenses for each enterprise, calculating the cost of production is straightforward. Divide the total annual expenses by the total amount produced during the year. For example, if it cost $143,788 to grow 35,000 bushels of corn, the cost of production is $4.10 per bushel.

Why does this number matter? First, your cost of production tells you whether an enterprise is profitable. If your corn costs $4.10 per bushel to produce but the market price is only $3.90, you’re losing 20 cents per bushel sold. Every enterprise on the farm will have its own cost of production, and those margins will change from year to year as input costs and market prices fluctuate. One year corn may be your strongest enterprise, while another year the dairy herd or mushroom operation may generate the best returns.

Second, tracking your cost of production helps identify opportunities to manage expenses. Comparing costs from one year to the next can reveal where spending has increased and highlight areas, such as feed, labor, or fuel, where efficiencies may be possible.

Finally, knowing your cost of production strengthens your marketing decisions. If you sell directly to consumers, such as at a farmers market, you can use your cost of production to establish a selling price that includes a reasonable profit margin. For commodity producers, the number is equally valuable. If your corn costs $4.10 per bushel to produce and you have the opportunity to forward contract part of your crop at $4.40 per bushel, you know you’ll lock in a 30-cent profit on those bushels. Marketing tools like forward contracts, futures, and options become much more useful when you know your production costs.

Calculating your cost of production can be tedious, requiring careful recordkeeping and time spent organizing expenses. However, the payoff is significant. Understanding your numbers allows you to effectively price products, evaluate which enterprise(s) contribute the most to your farm’s success, identify opportunities to reduce costs, and make better-informed business decisions. In today’s volatile agricultural economy, knowing your cost of production isn’t just another bookkeeping exercise, it’s one of the best management tools a farm can have.
