Marketing Plan Calculator
Percentage-based marketing plan across pricing methods.
About this calculator
Most successful grain marketers don't try to time one perfect sale — they spread bushels across several pricing methods and months to average into a good price while managing risk. This calculator lets you split your total expected production across four buckets — harvest cash sales, pre-harvest forward contracts, on-farm storage sold later, and futures/options hedges — each with its own expected price. It multiplies each bucket's bushels by its price to get a revenue figure, sums all four, and divides by total bushels to produce your weighted average price: the blended price you'd actually realize if every bucket performs as expected.
Total revenue is the dollar sum across all methods. Two numbers matter for keeping the plan honest: allocation total percentage should sum to 100 — a complete plan assigns every bushel somewhere — and unallocated bushels shows what's left over (or, if your percentages add past 100%, this figure can go negative, a sign to fix your allocations before relying on the output). Because each method's price is an input you supply rather than a live market feed, the weighted average is only a planning estimate: forward and hedge prices reflect what you've actually locked in, while storage and un-priced harvest bushels use whatever price assumption you enter, so revisit the plan as those prices firm up during the marketing year.

How to Use This Calculator
- Enter Total Bushels to market and allocate percentages across: harvest cash sales, forward contracts, storage, and hedges.
- Enter the price for each marketing method: harvest price, forward price, expected storage price, and hedged price.
- Review Weighted Average Price blended across all marketing channels.
- Check Total Allocated Percentage — it must reach 100% for a complete marketing plan.
- Use Unallocated Bushels to identify production not yet assigned to a marketing method.

Frequently Asked Questions
What happens if my four percentages add up to more than 100%?
The unallocated bushels figure is total bushels times one minus the total allocated percentage, so if your percentages sum past 100% that figure goes negative — a clear sign you've over-committed bushels you don't have and need to scale back one or more buckets before trusting the weighted average price.
How exactly is the weighted average price calculated?
Each bucket's bushels are multiplied by that bucket's price to get a revenue figure, all four revenue figures are summed into total revenue, and total revenue is divided by total bushels. It's a revenue-weighted blend, so a bucket carrying more bushels pulls the average toward its own price more than a smaller bucket does.
Why does the calculator ask for an expected storage price if I haven't sold that grain yet?
The storage bucket's price is a planning assumption, not a locked-in number — unlike your forward-contract and hedged prices, which reflect prices you've actually secured, the storage price is your best estimate of what you'll get when you eventually sell out of the bin. That's why the plan is meant to be revisited as the marketing year progresses and that assumption firms up.
Does the order in which I make these sales during the year affect the calculated result?
No — the calculator only cares about the final percentage split and price assigned to each of the four buckets, not when during the year each sale happens. It's a static weighted-average model of a completed plan, not a timeline, so two plans with the same allocations and prices produce the same weighted average regardless of sequencing.
