Storing corn makes financial sense only if the value of waiting covers the costs and risks you take on. A higher price later is not enough by itself. Compare the money available from selling now with the net proceeds from a later delivery, using your own farm’s costs.
Write down the sell-now alternative
Start with a current cash bid for the grain you can deliver. Note the buyer, delivery period, quote time and any costs or deductions. This is the alternative against which you compare storage. If your later sale is still unpriced, label that future price as an assumption rather than an offer you can accept today.
Identify the extra costs of waiting
Iowa State University Extension’s Cost of Storing Grain identifies storage charges, interest on inventory, extra drying and shrink, handling and quality deterioration as relevant costs. Commercial storage charges apply when you use that service. Existing bin costs that occur whether or not you store the crop are different from the additional costs caused by this storage decision; a new-bin investment needs its own analysis.
Money tied up in grain also has a cost. Include applicable financing expense or the return you forgo by delaying the sale. Do not count the same cost twice. Use the buyer’s actual terms and your own operating figures instead of assuming one standard storage cost applies to everyone.
A simple break-even example
Imagine that selling now would leave $4.00 per bushel after the delivery costs you have included. You estimate another $0.25 per bushel in costs to carry and deliver the grain later. On those assumptions, a later price of $4.25 would merely match the sell-now alternative. A hypothetical $4.30 later price would leave only $0.05 per bushel above it.
These numbers are invented to demonstrate the comparison. They are not today’s corn prices, a price forecast or typical storage charges. The example assumes the additional costs are all expressed per comparable saleable bushel. Adjust for losses, quality changes and any costs omitted from your estimate before relying on a calculation.
Check basis and the delivery window
A change in the futures market is only part of the potential change in your cash price. Local basis can strengthen or weaken too. The University of Wisconsin–Madison Extension basis guide explains how cash and futures prices relate. A historical seasonal pattern is a reference, not a promise of a better bid when your grain is ready.
Use a decision worksheet
- Record the current net cash-sale alternative.
- Choose a specific later delivery date.
- Estimate additional storage, financing, handling and delivery costs.
- Account for expected saleable bushels and quality risk.
- Calculate the later net price needed to match selling now.
- Review cash needs, bin space and the consequences if prices fall.
If the result depends on an uncertain price increase, write down that dependency. Revisit the comparison as costs, grain condition, cash needs or bids change. For the broader sale decision, read our corn selling checklist and cash-bid comparison guide.
