Moisture Shrink Calculator

Calculate grain moisture shrink, dry bushels, shrink bushels, water loss, marketable bushels, drying cost, grain value, and net value after drying. Use this moisture shrink calculator for corn, soybeans, wheat, oats, barley, sorghum, rice, and other stored grain.

Calculate Moisture Shrink

Dry Bushels = Wet Bushels × (100 − Current Moisture) ÷ (100 − Target Moisture).

How the moisture shrink calculator works

Moisture shrink:
The calculator compares current moisture with target moisture to estimate how many bushels are lost when water is removed.

Dry bushels:
Wet bushels are adjusted by the dry matter ratio to estimate bushels at the target moisture level.

Marketable bushels:
Handling shrink and additional dockage are subtracted after moisture shrink.

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

Why use a moisture shrink calculator?

A moisture shrink calculator helps estimate grain quantity and value after drying grain from harvest moisture to a target sale or storage moisture.

It can help compare wet bushels, dry bushels, moisture points removed, shrink bushels, handling shrink, drying cost, grain value, and net value.

What your result means

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

Moisture shrink formulas

Frequently asked questions

How do you calculate moisture shrink?

Divide dry matter at the current moisture by dry matter at the target moisture, multiply by wet bushels, then subtract the result from wet bushels.

What are dry bushels?

Dry bushels are the estimated bushels remaining after grain is adjusted from current moisture to the target moisture level.

Why does wet grain shrink when dried?

Drying removes water weight from the grain. Since bushels are tied to weight and moisture, removing water reduces the number of saleable bushels.

What is handling shrink?

Handling shrink is extra loss from moving, cleaning, drying, dockage, fines, spillage, or other grain handling activity.
