Grain Shrink Calculator

Calculate grain shrink, moisture shrink, handling shrink, dockage shrink, dry bushels, marketable bushels, grain weight, shrink value loss, drying cost, and net grain value. Use this grain shrink calculator for corn, soybeans, wheat, oats, barley, sorghum, rice, and other harvested grain.

Calculate Grain Shrink

Grain Shrink = Moisture Shrink + Handling Shrink + Dockage + Other Losses.

How the grain shrink calculator works

Moisture shrink:
The calculator estimates bushels lost from drying grain from current moisture to target moisture.

Handling and dockage shrink:
Additional shrink percentages are applied to estimate handling loss, foreign material, dockage, and other grain loss.

Marketable bushels:
Wet or gross bushels are reduced by all shrink categories to estimate saleable grain.

Net value:
Marketable bushels are multiplied by adjusted price, then drying, handling, and storage costs are subtracted.

Why use a grain shrink calculator?

A grain shrink calculator helps estimate how many bushels remain after moisture removal, dockage, handling loss, and other deductions.

It can help compare wet bushels, dry bushels, moisture points, shrink factor, dockage, marketable bushels, grain weight, shrink value loss, drying cost, and net grain value.

What your result means

Your result shows estimated moisture shrink bushels, handling shrink, dockage shrink, additional loss, total shrink, total shrink percent, marketable bushels, grain weight, shrink value loss, drying cost, handling cost, storage cost, gross value, and net grain value. These are estimates based on the values you enter.

Grain shrink formulas

Frequently asked questions

How do you calculate grain shrink?

Estimate moisture shrink from drying grain to target moisture, then add handling shrink, dockage, foreign material, and any other loss percentages.

What is moisture shrink?

Moisture shrink is the reduction in bushels or weight when water is removed from grain during drying.

What are marketable bushels?

Marketable bushels are the estimated bushels remaining after moisture shrink, handling shrink, dockage, and other losses are subtracted.

Why does grain shrink vary by elevator?

Grain shrink can vary because elevators may use different moisture schedules, shrink factors, dockage rules, grade standards, and handling fees.
