Silage Pile Calculator

Calculate silage pile volume, silage tons, dry matter tons, feed days, shrink loss, storage value, face removal rate, and pile capacity. Use this silage pile calculator for drive-over piles, bunker silos, corn silage, haylage, earlage, sorghum silage, and other forage storage planning.

Calculate Silage Pile

Silage Tons = Pile Volume × Density ÷ 2,000.

How the silage pile calculator works

Pile volume:
The calculator estimates pile volume from length, bottom width, top width, and height based on the selected pile shape.

As-fed tons:
Pile volume is multiplied by silage density, then divided by 2,000 to estimate tons of silage.

Dry matter tons:
As-fed tons are multiplied by dry matter percentage to estimate dry matter tons.

Feed days:
Usable silage is divided by daily feed needs to estimate how long the pile may last.

Why use a silage pile calculator?

A silage pile calculator helps estimate storage capacity, feed inventory, shrink loss, dry matter inventory, and feedout planning.

It can help compare pile size, density, dry matter, shrink, spoilage, feed days, face removal, silage value, harvest cost, cover cost, and net feed value.

What your result means

Your result shows estimated pile volume, gross as-fed tons, usable as-fed tons, dry matter tons, shrink tons, spoilage tons, daily feed use, feed days, silage value, harvest cost, cover cost, net value, and face removal estimate. These are estimates based on the values you enter.

Silage pile formulas

Frequently asked questions

How do you calculate silage pile tons?

Estimate pile volume in cubic feet, multiply by silage density in pounds per cubic foot, then divide by 2,000 to convert pounds to tons.

How do you calculate dry matter tons in silage?

Multiply as-fed silage tons by dry matter percentage. For example, 1,000 as-fed tons at 35% dry matter equals 350 dry matter tons.

Why include shrink and spoilage?

Shrink and spoilage reduce the amount of usable feed available from the pile. Losses can come from fermentation, air exposure, surface spoilage, and feedout management.

How do you estimate how long a silage pile will last?

Divide usable as-fed tons by daily feed use. Daily feed use is animals fed multiplied by pounds fed per head per day, divided by 2,000.
