Corn Crop Budget Template: Line Items Every Farmer Needs

GrainKit — Grain Marketing Tools for Midwest Farmers

Every spring, corn farmers make one of the most important financial decisions of the year: whether to plant, how much to put in the ground, and at what price they need to sell to come out ahead. A crop budget template is the tool that makes those decisions based on math instead of gut feeling.

This guide walks through every line item a corn crop budget should include, what realistic 2024 costs look like in the Midwest, and how to use your budget to drive both planting and grain marketing decisions.

What Is a Crop Budget?

A crop budget is a per-acre cost estimate for producing a crop. It adds up every expense from planting through harvest and delivery, then divides by your expected yield to produce a single number: your break-even price per bushel.

That break-even number is the foundation of every grain marketing decision you make for the year. If cash corn is trading at $4.60 and your break-even is $4.10, you have margin to work with. If cash is at $3.80 and your break-even is $4.20, you're in a different conversation entirely.

A crop budget also helps you decide what land is worth renting and at what price — if a new parcel's cash rent pushes your break-even above what corn is trading at, you know before you sign the lease.

Crop Budget Line Items: What to Include

A complete corn crop budget should have three sections: variable costs, fixed costs, and overhead. Here's what belongs in each.

Variable Costs (Change With Each Crop Year)

Seed
Corn seed typically runs $280–$340/bag, with most farmers planting 32,000–34,000 seeds per acre. That puts seed cost in the $90–$120/acre range depending on hybrid pricing and population.

Fertilizer
Fertilizer is usually the largest single line item and the most volatile. A typical corn budget includes:

• Nitrogen (anhydrous ammonia or UAN): $80–$130/acre depending on rates and fall vs. spring application
• Phosphorus (DAP or MAP): $30–$50/acre
• Potassium (potash): $25–$40/acre
• Starter fertilizer: $15–$25/acre

Total fertilizer: $150–$245/acre in 2024 conditions.

Herbicides and Pesticides
A standard corn herbicide program runs $35–$60/acre. Add fungicide if you're treating for gray leaf spot or northern corn leaf blight: $18–$28/acre applied. Insecticide is situational — budget $10–$20/acre if you're in a rootworm pressure area.

Crop Insurance
Revenue protection at 85% coverage typically costs $25–$45/acre in central Iowa and Nebraska, depending on county APH and spring prices. This is non-negotiable for most lenders — include it even if you're cash-farming.

Drying
If you're harvesting at 20–22% moisture and drying to 15%, budget $0.025–$0.03 per point of moisture removed per bushel. On a 200 bu/acre corn crop at 21% moisture, that's roughly $30–$36/acre in propane and electric costs at today's energy prices.

Fixed Costs (Tied to Land and Equipment)

Land Rent
Cash rent in central Iowa runs $225–$300/acre for high-productivity ground. In western Iowa and eastern Nebraska, $180–$250/acre is more common. This is typically your largest fixed cost per acre and the first thing to stress-test when prices drop.

Equipment
Owned equipment depreciation, repairs, and fuel typically run $90–$140/acre for a full corn operation (planting, spraying, combining, grain cart, auger). If you're custom-hiring combining, budget $35–$55/acre for that separately and remove the owned-equipment estimate for harvest.

Interest on Operating Note
If you're borrowing to finance inputs, add an interest line. At 8% on a $550/acre input cost financed for 7 months, that's roughly $25/acre.

Overhead

Overhead covers the costs that exist regardless of what you plant: general liability insurance, accounting and legal, farm office expenses, vehicle expenses, and any hired labor not tied to a specific field operation. Overhead typically runs $25–$50/acre for a mid-size row crop operation.

How to Use Your Crop Budget

Once you have total cost per acre, divide by your APH yield (or your realistic yield expectation for the field):

A 500-acre corn farmer with $825/acre all-in cost and a 195 bu/acre APH has a break-even of $4.23/bu. That number should drive every pricing decision from the moment spring planting starts through fall harvest and into the basis season.

Compare your break-even to current futures and local basis throughout the year. When cash price exceeds break-even by a comfortable margin, that's a window to price bushels. When prices dip below break-even, you're either managing risk with the bushels you already sold or deciding how long to carry unpriced grain.

One line item that's getting more attention lately is how those seed, fertilizer, and feed inputs actually get from the retailer to your farm. If a co-op trip during planting or harvest is costing you more in time than it saves in fuel, see our look at what farm supply delivery service actually costs, including a worked example of GrainKit's own pilot delivery pricing. And if you're specifically trying to get seed to the farm without a town run mid-planting, see our piece on seed delivery near me for how on-demand seed delivery works.
