What does cost of production mean?
Cost of production is the total amount you spend to produce a unit of something, such as a bushel, a bale, a dozen eggs, a pound of meat or a flat of seedlings. It is the number you compare against the selling price to see if you are making or losing money on each unit.
It is different from your total farm expenses. Total expenses tell you what the whole farm spent. Cost of production splits that spending across each enterprise so you can see which parts of the farm are working.
How do you calculate it step by step?
First, pick one enterprise, such as laying hens or a hay field. Gather every cost that belongs to it over one production cycle. Then divide the total by the number of units produced.
Where a cost is shared, such as a tractor used for several jobs, decide on a fair way to divide it, such as by hours of use, and stay consistent from year to year.
Keep the work simple the first time. A rough figure for one enterprise teaches more than a perfect spreadsheet you never finish.
- List direct costs: seed, feed, bedding, vet care, packaging and fuel used for that enterprise.
- Add a share of overhead: insurance, equipment, buildings, fencing and utilities.
- Include interest on any money borrowed for that enterprise.
- Divide the total by the units you actually sold or produced.
Which costs do small farms leave out?
The two biggest omissions are your own labor and the cost of the land and equipment you already own. Leaving them out can make an enterprise look profitable when it is actually paying you nothing for your time.
It is fine to choose to farm for less than a wage, many people do. The goal is to make that a clear choice. Put a value on your hours, even a modest one, and see how the picture changes.
How do losses and shrink affect the number?
Not everything you grow or raise makes it to sale. Some produce spoils, some animals are lost, some eggs crack. Divide your costs by what you actually sold, not what you hoped to produce.
This is why a small improvement in survival or yield can matter more than a small cut in input cost. Keep track of losses so you know where they happen.
How does cost of production guide your price?
Your cost is a floor, not a price. Prices are set by the market, by your customers and by what your product offers that others do not. But knowing your floor tells you when to walk away from a low offer, when to raise prices, and when an enterprise is not worth the effort.
If the market price sits below your cost, you have four choices: lower your cost, raise your quality or find a better market, change the enterprise, or accept the loss on purpose.
Also watch for the opposite problem: pricing at cost plus a hope. A price should cover cost, pay you for your work and leave room for the bad year, which is why a thin margin is risky.
How should you use the results?
Compare your cost figures from year to year and, where available, to published budgets from your state extension service. Those budgets are examples, not targets, and your farm will differ. Use them to spot costs that look unusually high or low in your own numbers.
Do not make big decisions from one year of data. Weather, disease and price swings can distort a single season. Two or three years of records give you a pattern you can trust.
What about enterprises that share land and equipment?
Many small farms run several enterprises on the same acres, such as hay and a few cattle, or vegetables and chickens that follow them. Costs overlap, and benefits do too. Manure from animals may reduce fertilizer needs for crops. Decide how you will split shared costs and note your method so it stays consistent.
If you are unsure how to divide costs, ask an extension farm management educator. They often have worksheets designed for this exact question, and they can show you how other farms in your region handle it.
- Split shared machinery by hours used
- Split shared land by acres used
- Record shared benefits, such as manure, as a note rather than a guess
Key takeaways
- Cost of production is total cost divided by units produced and sold.
- Count your labor and the cost of land and equipment you already own.
- Your cost is a floor for pricing, not the price itself.
- Use several years of data before making big changes.
