Corn Cost Per Acre Calculator
Corn cost per acre is the number that decides whether a season made money. Add up everything an acre cost to plant, feed, spray, fuel, irrigate, and harvest, and you get the figure every other farm number is judged against. This calculator builds it from itemized input costs, per acre or for the whole farm, and carries it through to profit and break-even price.
One distinction up front: this is what it costs to grow corn on an acre. What an acre of land costs to buy is a different calculation, and this page keeps the two apart. A 100-acre budget is loaded as the worked example.
Input costs, per acre ($)
Profit strip (optional)
Blank cost fields count as zero, so skip any bucket your operation does not have. Land rent is not a line of its own: add it under Other if you want the full economic cost.
Quick Answer
Key takeaways
- This page costs growing corn, not buying land. The eight buckets are production inputs; the purchase price of an acre is handled by a different tool, linked below.
- Per-acre mode and whole-farm mode are the same math from two directions. Enter costs the way your records keep them.
- Break-even price is cost per acre divided by yield. It moves with both numbers, so a cheap crop on a poor yield can break even higher than an expensive crop on a good one.
- Land rent is not a preset line. Add it under Other if you want the full economic cost, and know that doing so raises the break-even by roughly the rent divided by the yield.

Not the land price: what this calculator is, and is not
Two different questions share the words cost per acre, and mixing them up produces nonsense budgets. This calculator answers the grower’s question: what did it cost to produce corn on one acre this season, counting seed, fertilizer, crop chemicals, fuel and labor, irrigation, and machinery? It is a production cost builder, the number you compare against yield and price to see whether the crop paid.
The other question belongs to land buyers: what does an acre cost to purchase, including closing costs spread over the acreage? That is a land price calculation, not a production budget, and it lives in the cost per acre calculator. If you rent ground instead of owning it, rent enters this page as a production cost under Other; the rental market itself is benchmarked by the cash rent calculator. Keeping the three ideas separate is what makes each number usable.
Two ways to enter your costs
Farmers keep records two ways, and the tabs match them. Per-acre mode is for budgets: extension crop budgets, including the enterprise budgets published by land-grant universities and summarized in the USDA Economic Research Service commodity costs and returns series, quote seed, fertilizer, and machinery per acre. Enter those figures, and the tool sums them into the cost per acre and multiplies by your acres for the farm total.
Whole-farm mode is for bookkeeping: the seed invoice, the fertilizer bill, and the fuel receipts for the entire operation. Enter the totals and the acres, and the tool divides. A 100-acre farm entering $11,000 of seed, $15,000 of fertilizer, $2,500 of herbicide, $2,000 of insecticide, $3,500 of fuel and labor, and $6,000 of machinery gets the same $400.00 per acre as the per-acre tab, because the underlying budget is identical. If your acreage figure is the shaky one, measure the field properly first with the acreage calculator: a 5% acreage error flows straight into a 5% cost error in totals mode.
Worked example: $400 an acre, $590 of profit
Every figure below is what the pre-filled calculator returns, in either mode.
| Bucket | Per acre | Whole farm (100 acres) |
|---|---|---|
| Seed | $110.00 | $11,000.00 |
| Fertilizer | $150.00 | $15,000.00 |
| Herbicide | $25.00 | $2,500.00 |
| Insecticide | $20.00 | $2,000.00 |
| Fuel and labor | $35.00 | $3,500.00 |
| Irrigation | $0.00 | $0.00 |
| Machinery and equipment | $60.00 | $6,000.00 |
| Other | $0.00 | $0.00 |
| Cost per acre | $400.00 | $40,000.00 total |
| Revenue at 180 bu \u00d7 $5.50 | $990.00 | $99,000.00 |
| Profit | $590.00 | $59,000.00 |
| Break-even price at 180 bu | $2.22 per bushel | |
Fertilizer is the biggest single bucket here at 37.5% of cost, which matches the pattern in published corn budgets, where fertilizer and seed together usually carry half the operating cost. That concentration is the management insight: a 10% fertilizer saving is worth $15 an acre on this budget, more than eliminating the entire insecticide line.
What belongs in each cost bucket
Buckets only help if every dollar lands in the same one every year. Seed takes the hybrid cost at your planted population, including seed treatments bought with the seed. Fertilizer takes nitrogen, phosphorus, potassium, sulfur, and lime, at applied rates rather than purchased tons if your inventory carries over. Herbicide and insecticide split the chemical program the way your dealer invoices it. Fuel and labor combines diesel and gas with hired and operator labor hours, which is how the category is defined in this tool; if you track them separately, add them together for this line.
Irrigation takes pumping energy, water charges, and irrigation repairs, and dryland growers simply leave it at zero, as the example does. Machinery and equipment is the bucket most often understated: it should carry ownership costs (depreciation, interest, insurance) plus repairs and custom hire, allocated to corn from the whole machinery bill. Other is the honest catch-all: crop insurance premiums, drying and hauling, interest on operating loans, and land rent if you choose to include it. Extension break-even guides, such as the Farm Progress explainer of the Nebraska corn budgets, make the same distinction between operating cost and full economic cost: your break-even only covers what you put in, so decide deliberately which version you are calculating.
From cost per acre to profit and break-even
The profit strip turns the cost figure into the two numbers marketing decisions hang on.
Read the break-even as a marketing floor, not a forecast. At $2.22, forward-contracting above that level locks a margin over this cost set; below it, you are betting on yield beating the estimate or on costs you did not count. One more use: if part of the crop will be chopped rather than combined, value that portion separately with the corn silage value calculator, because silage revenue follows forage value, not the grain price in this strip.
What competing calculators miss
The simplest competing tool for this keyword takes one total production cost and one acreage and divides. University break-even worksheets go deeper but live in spreadsheets and PDFs that assume you already keep enterprise accounts.
Miss 1: a single total input. One lump sum hides where the money goes. The eight itemized buckets here show fertilizer carrying 37.5% of the example budget, which is the information a cost-cutting decision actually needs.
Miss 2: per-acre records only. Many farms track invoices, not unit budgets. The whole-farm totals tab meets bookkeeping where it lives and still returns the per-acre figure.
Miss 3: cost with no profit context. A cost per acre alone does not say whether the season worked. The profit strip carries the same inputs through revenue, profit per acre, whole-farm profit, and break-even price in one run.
One honest limit: this is a cost builder, not a full enterprise budget. It has no separate lines for crop insurance, drying, storage, or interest, and no yield-based drying charges per bushel. Fold those into Other, and for a formal budget your extension service worksheet remains the fuller tool.
Frequently Asked Questions
Add up every input cost for the corn enterprise and divide by acres planted. If your records are already per acre, the sum of the per-acre figures is the cost per acre and the calculator multiplies it by acreage for the farm total. If your records are whole-farm invoices, enter them on the totals tab and the division happens there.
Whichever matches your records. Extension budgets are usually quoted per acre, which suits the first tab. Farm accounting tracks whole-farm bills, which suits the second. Both tabs run the same eight cost buckets and arrive at the same per-acre figure from the same underlying numbers.
Not automatically. There is no rent line, so add your cash rent or land charge under Other if you want the full economic cost per acre. Whether you include it changes the break-even price a lot: $250 of rent on a 180-bushel acre adds about $1.39 to the break-even corn price.
Multiply expected yield by expected price to get revenue per acre, then subtract cost per acre. The profit strip in the calculator does it for you: at $400.00 of cost, 180 bushels, and $5.50 a bushel, revenue is $990.00, profit is $590.00 an acre, and whole-farm profit on 100 acres is $59,000.00.
Cost per acre divided by yield per acre. At $400.00 an acre and 180 bushels, the break-even is $2.22 per bushel: any selling price above it leaves a margin on the costs you entered, and any price below it means the acre loses money on those costs.
No. This page measures what it costs to grow corn on an acre: seed, fertilizer, chemicals, fuel, irrigation, and machinery. The price of buying an acre of land, and closing costs spread over acreage, is a separate calculation with a different purpose.
