Free Online Corn Yield Calculator to Estimate Bushels Per Acre

Estimate Your Corn Harvest Potential

Number of harvestable ears in your 1/1000th acre sample plot.
Average number of kernel rows around the cob.
Average number of kernels in each row.
Estimate of kernels needed to make one bushel (common range: 75,000 - 90,000).

Use our free Corn Yield Calculator to accurately estimate your potential harvest in bushels per acre. Quickly assess your field's performance and plan for optimal crop management using key metrics like ear count and kernel details.

Formula:

Yield (bu/acre) = (Ears / 1/1000th Acre × Avg. Rows / Ear × Avg. Kernels / Row) / Kernels Per Bushel Factor × 1000

Where:

  • Ears per 1/1000th Acre: Number of harvestable ears in a measured 1/1000th acre plot.
  • Avg. Rows per Ear: Average number of kernel rows around the cob.
  • Avg. Kernels per Row: Average number of kernels in each row.
  • Kernels Per Bushel Factor: An estimate of kernels needed to make one bushel (typically 75,000 - 90,000).
