How it works
Grain shrink estimates the reduction in weight when moisture is removed.
Formula:
Shrink % = ((Start − Target) ÷ (100 − Target)) × 100
Final Bushels = Starting Bushels × (1 − Shrink %)
FAQ
What is grain shrink?
Grain shrink is the loss of weight that occurs when grain is dried to a lower moisture content.
Is shrink the same as dockage?
No. Shrink is moisture loss. Dockage is discounts from foreign material, damaged kernels, or test weight issues.
Does this calculator include handling loss?
No. This calculator estimates moisture shrink only. Handling loss may occur during drying and storage.
