Corn Yield Calculator

Your details

Switch between US bushels per acre and metric tonnes per hectare.
Total cultivated area of the field you sampled.
acres
Count every harvestable ear along a 1/1000-acre row section (17.4 ft of 30-inch rows, for example). Sample at least 3 locations and use the average.
ears
Count the kernel rows on one ear and the kernels in one row, then multiply. Average over at least 5 ears per sample location.
kernels
Small kernels result from drought or late-season stress; large kernels from ideal fill conditions. When unsure, use Medium.

Strong yield: ~199.1 bu/acre puts you above the US average.

  • Your estimated yield of 199.1 bu/acre is above the US national average of about 177 bu/acre.
  • At 199.1 bu/acre across your 100 acre field, you can expect roughly 19,911 bushels total.
  • This is a pre-harvest estimate - actual yield varies with late-season weather, harvest losses, and field variability. Sample at least 3-5 locations per field for a reliable average.

Next stepFor the highest accuracy, take samples in at least 5 representative locations, avoiding field edges, and average the results before harvest.
