Harvest Loss Calculator
Estimate bushels per acre lost during harvest and calculate revenue impact.
Inputs
How It Works
For corn, approximately 2 kernels per square foot equal 1 bushel per acre lost.
Bushels Lost = Kernels ÷ 2
Revenue Loss = Bushels Lost × Price
FAQ
How do I count kernels?
Count loose kernels in a measured 1 square foot area across several locations and average the results.
Does this apply to soybeans?
No. Soybeans use a different seed count conversion. This formula is commonly used for corn harvest loss.
Why is harvest loss important?
Even small kernel losses can significantly reduce overall farm profitability across large acreages.
About Harvest Loss
Harvest loss occurs when grain is left in the field during combining. Losses can result from improper header settings, excessive ground speed, moisture conditions, or equipment calibration issues.
Measuring harvest loss helps identify inefficiencies in combine setup and allows operators to make adjustments that improve overall yield recovery. Even a loss of 1–2 bushels per acre can translate into substantial financial impact across hundreds or thousands of acres.
Monitoring grain loss is a critical component of precision agriculture and supports improved profitability through better equipment management.
