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)

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.
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.
