Crop Yield Calculator
Calculate measured kilograms per hectare, gross field harvest, marketable harvest after loss, and metric tonnes. The field-grid visual expands one sample quadrat across the entered hectares and removes the loss share visibly.

Sample plot to marketable field harvest
Sample plot to marketable field harvestA measured quadrat scales to hectares and gross harvest before the entered handling-loss share is removed.
Exact scenario comparisonHarvest from sample plot (kg) changes while all other entered assumptions remain constant.

How to use Crop Yield Calculator
- Select multiple representative plots under a documented sampling plan.
- Measure harvested mass and area on a consistent moisture and cleaning basis.
- Apply separate harvest, handling, grading, and storage losses when higher precision is needed.
Calculator guide
Understanding Crop Yield Calculator
A crop-yield estimate scales a representative sample plot to field area, then separates gross biological harvest from marketable output after loss. The result is only as representative as the plot and moisture basis.
Calculation method
How the calculation works
Scale a representative plot harvest to kilograms per hectare, multiply by field area, and reduce the result by an entered loss allowance. Divide sample mass by plot area, multiply by 10,000 m² per hectare, multiply by field hectares for gross harvest, and reduce by one minus the entered loss rate.
Field method
Design a representative yield sample
Sampling discipline matters more than extra decimal places.
Worked situations
Practical examples
- 18 kg from 25 m² scales to 7,200 kg/ha.
- Across 12 ha, gross field harvest is 86,400 kg.
- After an 8% loss allowance, marketable harvest is 79,488 kg or 79.488 tonnes.
Better inputs
Useful tips
- Average several stratified samples rather than choosing a visually strong plot.
- State wet, dry, or standard-moisture basis.
- Compare modeled marketable yield with storage, transport, and buyer-grade capacity.
Before relying on the result
Limitations and common mistakes
- One sample mass and area are extrapolated uniformly across the field.
- Moisture, border effects, spatial variability, pests, harvest timing, grading, storage, and sampling uncertainty are excluded.
- Loss is applied as one constant percentage to gross harvest.
Reference
Key terms
- Sample plot
- Measured field subsection used to estimate yield.
- Yield per hectare
- Sample production normalized to 10,000 m².
- Gross harvest
- Field-scale output before entered loss.
- Marketable harvest
- Modeled gross output remaining after loss allowance.
Important note
Calculated from the entered field and production values. Confirm seed-lot data, equipment calibration, labels, local conditions, and applicable agronomic guidance.
Frequently asked questions
Why multiply by 10,000?
One hectare contains 10,000 square meters.
Should loss include moisture shrink?
Only if the entered gross and marketable weights use consistent definitions and the loss allowance is documented.
Can one plot represent 12 hectares?
It can produce arithmetic, but multiple representative samples are needed for credible inference.
Is marketable yield the same as revenue?
No. Revenue also requires grade, price, deductions, and sold quantity.
