Corn Yield Calculator
Calculate harvestable ears and kernels per acre, dry grain mass after harvest loss, bushels per acre, field production, gross revenue, and revenue per acre. A field-sampling diagram shows how plant population and kernel assumptions scale to the whole field.

Field sample to marketable corn yieldThe agronomic chain moves from plants and productive ears through kernels, dry grain, bushels, and field revenue.

Yield detail
Component reconciliation and kernel scenarios
How to use Corn Yield Calculator
- Sample representative field locations and count established plants and ears.
- Estimate kernels and dry kernel mass on a consistent moisture basis.
- Separate biological yield from harvest loss, storage loss, price basis, and final settlement.
Calculator guide
Understanding Corn Yield Calculator
Corn yield can be traced from established plants to productive ears, kernels, dry grain mass, standard bushels, and field revenue. This calculator exposes every conversion instead of applying a single yield guess.
Calculation method
How the calculation works
Convert established plants to harvestable ears and kernels, apply the entered dry kernel mass and field loss, and convert dry grain mass to 56-pound bushels. Apply productive-ear share to plants, multiply by kernels per ear and dry kernel mass, subtract harvest loss, convert kilograms to pounds, divide by 56 pounds per bushel, and multiply by acres and price.
Sampling record
Make a field estimate reproducible
Sampling documentation often matters more than extra displayed decimals.
Worked situations
Practical examples
- 32,000 plants at 95% productive ears produces 30,400 ears per acre.
- Kernel count and dry kernel mass jointly determine grain mass.
- A 3% harvest loss is removed before bushels and revenue are calculated.
Better inputs
Useful tips
- Use multiple sampling zones across soil, hybrid, and damage patterns.
- Confirm whether quoted market weight and measured kernel mass share the same moisture basis.
- Stress price separately from physical yield.
Before relying on the result
Limitations and common mistakes
- Sampling error, moisture shrink, hybrid variability, lodging, borders, disease, storage loss, grade, and basis are excluded.
- The result is not an agronomic recommendation or guaranteed crop settlement.
- Average kernels per ear can hide large spatial variation.
Reference
Key terms
- Productive ear share
- Entered percentage of established plants producing harvestable ears.
- Dry kernel mass
- Average kernel weight on the chosen dry basis.
- Harvest loss
- Entered share removed before field production.
- Standard bushel
- A 56-pound corn weight conversion used here.
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 use kernel weight?
Kernel count alone cannot determine grain mass when kernel size varies.
Does the result include moisture shrink?
Only if the entered kernel weight already reflects the desired dry basis.
Is a bushel a volume here?
No. The conversion uses the standard 56-pound corn weight.
Does gross revenue equal profit?
No. Seed, inputs, machinery, drying, storage, transport, basis, and other costs are excluded.
