Dry Matter Calculator

Calculate dry matter, moisture percentage, dry matter intake, as-fed feed amount, dry matter tons, and feed cost per dry matter ton. Use this dry matter calculator for hay, silage, pasture, grain, complete feed, livestock rations, and forage comparisons.

Calculate Dry Matter

Dry Matter = As-Fed Amount × (100 − Moisture %) ÷ 100.

How the dry matter calculator works

Dry matter amount:
The calculator subtracts moisture from 100 to find dry matter percentage, then multiplies by the as-fed amount.

As-fed needed:
Enter a target dry matter amount to estimate how much feed must be fed on an as-fed basis.

Moisture test:
Wet sample weight and dry sample weight can be used to estimate dry matter percent and moisture percent.

Dry matter cost:
Feed price and delivery cost are adjusted to calculate cost per dry matter ton.

Why use a dry matter calculator?

A dry matter calculator helps compare feeds with different moisture levels.

It can help compare hay, silage, pasture, grain, complete feed, feed intake, dry matter intake, dry matter tons, ration cost, and feed value.

What your result means

Your result shows dry matter percentage, moisture percentage, dry matter pounds, dry matter tons, as-fed feed needed, dry matter intake per head, total dry matter intake, feed cost per dry matter ton, cost per dry matter pound, and total feeding cost. These are estimates based on the values you enter.

Frequently asked questions

What is dry matter?

Dry matter is the part of feed left after water is removed. It includes nutrients such as fiber, protein, energy, minerals, and other feed solids.

How do you calculate dry matter?

Subtract moisture percentage from 100 to get dry matter percentage, then multiply the as-fed amount by the dry matter percentage.

Why compare feed on a dry matter basis?

Feeds can have very different moisture levels. Dry matter basis makes it easier to compare hay, silage, pasture, grain, and mixed rations fairly.

How do you calculate cost per dry matter ton?

Divide the landed as-fed cost per ton by the dry matter percentage as a decimal. For example, $180 per ton at 90% dry matter equals $200 per dry matter ton.
