Store It or Sell It? How to Run the Numbers Before Harvest
Every fall it's the same question, and it never gets easier: haul it to town at harvest, or put it in the bin and sell later? Ask around the coffee shop and you'll hear it both ways. One neighbor swears he always makes money storing. Another got burned holding a crop that never rallied and won't do it again. Both are telling the truth about their own year. The trouble is, neither one's year is your year — and the only way to know which side of that line you're on is to run your own numbers.
The good news: the math isn't complicated. It just has more pieces than most people hold in their head at once, which is why the decision so often comes down to a gut call. Let's lay the pieces out.
The decision, in one sentence
Storing grain is worth it when the price you expect to get later is enough more than the harvest price to cover what it costs you to hold it. That's the whole thing. The two halves are the carry (how much more the later price is) and the cost to hold (everything you give up by not selling now). If the carry beats the cost, storing pencils. If it doesn't, it doesn't. Every bit of the rest is just figuring those two numbers honestly.
Half one: what's the grain worth later?
The later price isn't one number you can look up — you build it. Start with the futures carry: the difference between the nearby contract and a later one tells you what the market is paying you to wait. Then adjust for your basis — the gap between the futures price and what your local elevator actually pays — because basis often changes between harvest and later in the year, and that change can add to or eat into your carry. Put those together and you've got a realistic picture of what your grain might bring if you hold it, instead of a hopeful guess pulled from the high print on a market you saw once.
Notice what this is not: it's not a prediction that prices will go up. Nobody knows that. It's a structured estimate built from the carry and basis the market is actually showing you right now, so you're weighing a real number against a real cost instead of holding on hope.
Half two: what does it actually cost to hold it?
This is the half people underestimate, because most of the costs are quiet. Holding grain isn't free even if you own the bin outright. Here's what belongs in the tally:
Interest. The money tied up in unsold grain is money you can't use — whether that's interest you're paying on an operating note, or interest you're not earning. Either way it's real, and it runs the whole time the grain sits.
Shrink. Grain loses weight as moisture comes down, and shrink is a cost whether it happens in your bin or gets docked at the elevator. It has to be counted on both sides or the comparison isn't fair.
Drying. If you're putting it away wetter and drying it down, the LP or fuel and the electricity are part of the cost of storing — not a separate thing.
Handling and trucking. Moving it in, moving it out, hauling it later. Sometimes storing just delays the trucking; sometimes it adds a trip.
The bin itself. If you built or rented storage, that cost belongs somewhere too — spread across the bushels it holds.
Add those up and divide by your bushels, and you get your cost to hold, per bushel, per length of time you hold it. That's the number the carry has to beat.
Putting the two halves together
Now it's a clean comparison. On one side, the extra you expect from carry and basis. On the other, your honest cost to hold. Subtract, and you've got the net advantage — or disadvantage — of storing, in cents per bushel. Positive means storing pencils on the numbers you plugged in. Negative means the carry isn't paying you enough to wait, and moving it at harvest is the stronger play on those numbers.
The reason to write it down instead of eyeballing it is that the answer swings on things that move. A better basis later, a nickel more of carry, a wetter crop that costs more to dry — each one tips the scale. When you can see the pieces, you can also see what would have to change to flip the decision, and you can watch for exactly that.
The other decisions that ride along
Store-or-sell is the one everybody asks about, but it rarely travels alone. If you're short on space, it turns into should I build a bin — which is its own six-figure calculation of build cost, payback, and cost per bushel, and a question of whether building, renting, or just paying commercial storage comes out cheapest for you. If you run livestock, there's a cousin question: sell the raised grain and buy feed, or feed your own? Same style of math — what you'd net selling versus what buying equivalent feed would cost. They're all the same muscle: lay out the real costs, weigh them against the real alternative, and let the numbers narrow it down.
You don't have to have it perfect
You won't know your final basis, your exact shrink, or where the market goes. That's fine. Run it on realistic figures, mark the assumptions you're least sure of, and update as the picture clears. A store-or-sell decision figured on honest numbers — even rough ones — beats a gut call every time, because a gut call can't show you why it landed where it did, and it can't tell you what would have to change to land somewhere else. The point isn't a number carved in stone. It's walking into harvest knowing where your line sits, so whatever you decide, you decided it on purpose.
I build an Excel toolkit that walks through this exact math — the carry-and-basis side, the full cost to hold, bin sizing and payback, drying cost, and the store-or-sell and sell-or-feed comparisons — so the pieces are in one place instead of scattered in your head. You enter your figures; it does the arithmetic; the file is yours to keep. Find the Grain Storage Decision Toolkit at https://www.farmwifefinancialsllc.com/store/p/grain-storage-decision-toolkit.
