Grain Storage Loss Calculator
Estimate storage shrink percentage and revenue loss during grain storage.
Inputs
How It Works
Bushels Lost = Initial Bushels × (Loss % ÷ 100)
Revenue Lost = Bushels Lost × Grain Price
FAQ
What causes storage loss?
Storage loss can occur due to moisture migration, spoilage, insect activity, and handling losses.
What is a typical storage loss percentage?
Well-managed grain storage may experience 0.5%–2% loss depending on conditions and storage duration.
Does this include shrink from drying?
No. This calculator estimates storage-related loss only. Use moisture shrink calculator for drying adjustment.
About Grain Storage Loss
Grain storage loss refers to the reduction in saleable bushels during the storage period. Even when properly dried, grain can experience shrink due to moisture migration, handling losses, insect activity, and natural respiration.
Proper aeration, temperature monitoring, and moisture control significantly reduce storage losses. However, even small percentages of shrink can translate into meaningful financial impact when large volumes of grain are stored for extended periods.
Understanding potential storage loss allows producers to evaluate whether on-farm storage or immediate sale provides better financial outcomes. Combining storage loss analysis with drying cost and moisture shrink calculations provides a complete picture of post-harvest grain economics.
