Crop Yield Calculator
Convert yield per area into total production, bushels and revenue.
Please note: Planning figures based on published averages. Soil type, climate, variety, season and local practice all shift these results substantially. Base real decisions on a soil test, local extension guidance and the product label — particularly for fertiliser, lime and any crop protection product, where the label is a legal document.
What the Crop Yield Calculator does
Yield converts to total production by simple multiplication, but the units are the difficult part: bushels are a volume measure with a different weight for every crop, and grain above target moisture is docked because the buyer is paying for water rather than grain.
Formula
Total = Yield per hectare × AreaBushels = Total kg ÷ kg per bushelShrunk weight = Weight × (100 − Moisture) ÷ (100 − Target)
Inputs explained
| Input | Unit | Required | Notes |
|---|---|---|---|
| Crop | one of 8 options | Yes | — |
| Yield | number | Yes | Accepts more than 0. |
| Yield measured in | one of 3 options | Yes | — |
| Area harvested | number | Yes | Accepts more than 0. |
| Area harvested unit | one of 4 options | Yes | — |
| Harvest moisture | % | Optional | Leave at 0 to skip the dry weight adjustment. |
| Target storage moisture | % | Optional | — |
| Price per tonne | selected currency | Optional | Accepts 0 or more. |

How to use it
- Choose Crop and Yield measured in.
- Enter Yield and Area harvested.
- Optionally add Harvest moisture, Target storage moisture and Price per tonne.
- Select Calculate.
Worked example
Wheat yielding 8 t/ha over 25 hectares.
- Crop
- Wheat
- Yield
- 8 t/ha
- Area
- 25 ha
200 tonnes in total. At 27.2155 kg per bushel that is 7,349 bushels, or 118.9 bu/acre.
Reading the result
- "Revenue per hectare" is the figure to compare against per-hectare input costs from a tool like the gross margin calculator — total revenue alone does not tell you profitability without that per-area comparison.
- Everything in "total production at other yields" scales linearly with yield, making it a quick way to see the revenue swing from a yield miss without re-entering the whole calculation.
Assumptions and limitations
- The shrink calculation assumes dry matter is exactly conserved and moisture is the only thing lost — it does not account for physical losses such as spillage or handling on top of pure moisture loss.
- "Price per tonne" is a single flat figure for the whole crop — it does not model quality discounts or premiums for protein content, test weight or damage that real grain contracts often apply.
Common mistakes
- Leaving "harvest moisture" at its default of 0 (meaning "skip the adjustment") when the crop is actually above target moisture — the revenue figure then reflects wet weight, overstating what a buyer would pay.
- Comparing "yield per acre" in bushels against a hectare-based yield from another source without converting — the two are not interchangeable at face value.
Frequently asked questions
Why does a bushel weigh different amounts for different crops?
Because it is a volume — about 35.24 litres. A bushel of oats weighs 32 lb and a bushel of wheat 60 lb simply because the grains pack differently.
What is shrink?
The weight lost when grain is dried to storage moisture. Sell at 18% when the target is 14% and roughly 4.7% of the weight disappears as water.
