Store Vs Sell Grain | Farm Decision Guide

At harvest, you have two choices: sell the grain now and take whatever the elevator is offering, or put it in the bin and sell it later. It sounds simple. It isn’t. The decision involves your breakeven, the current basis, the futures carry, your storage costs, your cash flow position, and your honest read on where prices are going, which no one knows for certain. This guide gives you the framework to make the call with your eyes open. If you farm corn and soybeans in central Oklahoma or Kansas, these are the numbers to run before the combine stops.

Start With Your Breakeven

Before the store-vs-sell question means anything, you need to know your cost of production per bushel. If you don’t have this number, sharpen your pencil before harvest.

Your breakeven is: total cost of production divided by expected bushels per acre.

Total cost of production includes

Seed
Fertilizer (input costs often run 35 to 50 percent of total)
Chemical and crop protection
Fuel and repairs
Land cost (cash rent or owned-land cost)
Crop insurance premium
Interest on operating loan
Machinery depreciation
Overhead and labor

If cash prices at harvest are above your breakeven, you have a profit at any price above that line. The store-vs-sell decision is about optimizing, not surviving.

If cash prices are below your breakeven, storing is a choice to speculate with borrowed money or equity. Be clear-eyed that this is what you’re doing. You’re betting the market will recover enough to cover your costs plus carrying charges.

Extension budgets are useful benchmarks, but your rent, yield history, and input program are what matter on your ground. A 200-bushel corn farm and a 140-bushel farm on the same cash rent have different breakevens.

ISU 2025 reference breakevens (as a benchmark, use your own numbers)

Corn: approximately $4.10 to $4.50 per bushel depending on rent and yield
Soybeans: approximately $9.80 to $10.50 per bushel

Request the crop breakeven calculator to plug in your actual costs before you make harvest marketing decisions.

Understand Basis Before You Decide

Basis is the difference between the local cash price at your elevator and the nearby futures price:

Basis = Local Cash Price minus Futures Price

Basis reflects local supply, demand, transportation costs, and elevator margin. A negative basis, which is almost always the case in the interior US, means the local cash price is below the futures price.

Why basis matters for store-vs-sell

If basis is weak at harvest (very negative), the elevator is offering you a worse deal relative to the futures market
Storing and selling when basis strengthens captures the basis improvement, separate from any futures price movement
Basis typically strengthens from fall harvest through winter and into spring as local supply tightens

In Oklahoma and Kansas, harvest basis on corn often runs its weakest in October and November when every farmer in the region is hauling at once. By February or March, that same elevator may be bidding 10 to 25 cents better on the same futures contract, even if futures haven’t moved much.

How to use basis in your decision

Watch your local elevator’s historical basis for the past 3 to 5 years. Most grain merchandisers can pull this up, and your extension agent may have regional basis charts. If current harvest basis is weaker than the historical average, there’s an argument for storage on the basis side alone, even if futures don’t move.

Write down your local basis today and what it typically is in March. The difference is your expected basis gain before you subtract carrying costs. If historical basis recovery is only 8 cents and your carrying cost is 28 cents, the math doesn’t work on basis alone.

Calculate Your Carrying Costs

Storing grain is not free. Every month in the bin has a cost, and that cost must be recovered by a higher price when you sell.

Commercial elevator storage

Current commercial storage for corn runs approximately $0.025 to $0.035 per bushel per month. Storing from October to March (5 months) costs approximately $0.12 to $0.18 per bushel. Soybeans cost more to store commercially.

On-farm storage

On-farm storage has a lower variable cost but has a capital cost that is often ignored:

Electricity for aeration and drying
Shrink (corn stored dry will lose weight to moisture change and handling)
Opportunity cost of capital: the grain in your bin is equity that could pay down your operating note

Before you commit to filling every bin, use the grain bin volume calculator to figure bushel capacity by diameter, height, and grain type.

Interest cost, the number most farmers underestimate

If you owe on an operating loan at 8 percent interest and you have $400,000 worth of corn in the bin, carrying it for 5 months costs:

$400,000 x 8% x (5/12) = $13,333 in interest, or about $0.13 per bushel on 100,000 bushels

Run your operating note balance through the farm loan calculator to see what interest is costing you on grain you’re holding instead of selling.

If you’re using cash (no loan), calculate the forgone return on that money instead. What could it earn in a money market or short-term CD?

The minimum price increase needed to justify storage

Add your carrying costs together:

Commercial storage: $0.15 per bushel (5 months)
Interest: $0.13 per bushel
Total: approximately $0.28 per bushel minimum price improvement needed to break even on storage

If you don’t believe the market will offer $0.28 per bushel more by spring, selling at harvest is the better math.

What the Futures Market Is Telling You

The futures carry (or calendar spread) is what the futures market is offering to store grain from one month to a later delivery month.

How to read it

If December corn futures are at $4.20 and March corn futures are at $4.42, the carry is $0.22 over 3 months, or about $0.073 per month. Compare this to your monthly carrying cost (commercial storage plus interest). If the carry exceeds your carrying cost, the market is offering to pay you to store.

The key principle: “You can’t capture the carry unless you sell the carry.”

This means: if you want to lock in the carry, you need to make a deferred sale (forward contract or hedge) for the later delivery month. Holding unpriced grain in storage hoping for higher prices is speculation. The carry is not guaranteed unless you sell it.

In a carry market (common in high-supply years like 2024 and 2025)

Deferred months are priced higher than nearby
The market is telling you: we have too much grain right now, store it and we’ll pay you later
Capturing the carry with a deferred sale is a rational, relatively low-risk strategy

In an inverse market (rare, occurs in supply-short years)

Nearby months are priced higher than deferred
The market is telling you: sell now, don’t store
Storing in an inverse market means you’re selling later at a lower price than you could get today

Your Cash Flow Position Changes the Calculus

Economic theory says: farms with better cash flow are better positioned to store grain. A farmer who needs to make a loan payment in November and has no other cash source must sell in October. The math of storage doesn’t matter if you can’t afford to wait.

Operating notes come due. Input bills for next year’s crop arrive in December and January. Landlords want rent. Grain in the bin doesn’t pay any of those bills until you sell it. Your lender may also ask what percentage of your crop is sold versus stored before they renew your operating line.

Honest questions to answer before storing

Do I have cash or credit to cover operating expenses through spring without selling this grain?
Is my operating loan balance where it needs to be at year end?
Does my lender have visibility into my storage position and are they comfortable with it?
Do I have a plan, a price target or a date, to sell out of storage? Storing without a plan is how grain stays in the bin for 18 months.

Use the farm loan calculator to model what selling now versus holding does to your note balance and interest expense.

The Decision Framework

Run through these four questions in order. Write your answers down. Harvest week is not the time to do this math for the first time.

Step 1: Is the current cash price above my breakeven?

Yes: You have flexibility. Make the store-vs-sell decision on merit.
No: You’re speculating on a recovery. Understand and accept that risk before storing.

Step 2: Is harvest basis weaker than historical average?

Yes: There may be basis improvement to capture by storing, even if futures don’t move. Determine how much historical basis tends to recover by February through April.
No: Basis is already near normal. Storage decision rests on futures price outlook only.

Step 3: Does the carry in the futures market cover my carrying costs?

Yes, and I want to lock it in: Make a deferred forward sale. Store the grain, sell the carry, collect the known profit.
Yes, but I want to speculate on higher prices: Store unpriced. Understand this is a bet on price direction.
No: The market isn’t paying you to store. Selling at harvest is likely the better economic decision.

Step 4: Do I have the cash flow to wait?

Yes: You can afford to let the market work.
No: Sell enough to meet your cash obligations. Store the rest if the above analysis supports it.

Most years, the answer isn’t all store or all sell. Sell enough to cover operating costs and loan payments. Store the rest if basis, carry, and cash flow support it.

When Storing Makes Clear Sense

Harvest basis is significantly weaker than historical average (basis improvement is likely)
The futures carry exceeds your carrying costs and you can lock it in with a deferred sale
You have on-farm storage (lower variable cost than commercial)
Your cash flow position is solid. You don’t need the money.
You’ve set a price target or decision date and you’ll stick to it

Check your actual bin capacity with the grain bin volume calculator so you know how many bushels you’re committing before you default to storage.

When Selling at Harvest Makes Clear Sense

Cash price is at or above your breakeven and profit is available today
The futures market is in an inverse. Nearby prices are higher than deferred.
You have significant operating debt that needs to come down
You don’t have on-farm storage (commercial costs are too high to justify waiting)
You have no conviction about where prices are going and you’d rather take certainty

Taking a profit at harvest is not a failure of marketing. It’s a success of knowing your breakeven and recognizing when the market is paying you. If your breakeven is $4.35 and the elevator is paying $4.55 in October, you have 20 cents of profit per bushel in hand unless basis recovery and carry clearly exceed your carrying costs.

The farmer who beats his neighbors on marketing isn’t the one who made the best guess on price direction. It’s the one who ran the math every year, knew his breakeven, watched his basis, and made a plan before harvest instead of a decision under pressure the week of the sale. Do the math before you do the deal.
