Harvest Loss Calculator
Estimate grain lost during harvest in bushels per acre and total dollar value. Helps evaluate combine efficiency and header adjustments.
Inputs
How It Works
Bushel Loss = Pounds Lost ÷ Test Weight
Dollar Loss = Bushel Loss × Crop Price
For example, 112 lbs lost in corn at 56 lb test weight equals 2 bushels per acre lost.
Why Harvest Loss Matters
Even small combine losses can significantly impact profitability. Losing 2 bushels per acre on 1,000 acres equals 2,000 bushels of lost revenue.
Proper combine calibration, header adjustment, and ground speed management can reduce harvest loss dramatically.
FAQ
How do I measure harvest loss?
Use a drop pan or count kernels in a measured area behind the combine.
What is typical acceptable loss?
Many operators aim for less than 1–2 bushels per acre depending on crop.
