Harvest Loss Calculator

Calculate harvest loss, crop loss per acre, total bushels lost, harvest loss percentage, grain value loss, header loss, combine loss, field loss, and net harvested value. Use this harvest loss calculator for corn, soybeans, wheat, oats, barley, sorghum, rice, and other harvested crops.

Calculate Harvest Loss

Harvest Loss = Pre-Harvest Loss + Header Loss + Combine Loss + Cleaning Loss + Other Loss.

How the harvest loss calculator works

Bushels per acre method:
The calculator adds pre-harvest, header, separator, cleaning, and other losses to estimate total loss per acre.

Percent method:
The calculator applies the known harvest loss percentage to expected crop production.

Total loss:
Loss per acre is multiplied by harvested acres to estimate total lost bushels and value loss.

Net harvested crop:
Expected production is reduced by harvest loss, moisture shrink, and dockage to estimate net harvested bushels.

Why use a harvest loss calculator?

A harvest loss calculator helps estimate how much crop and value may be lost during harvest and where losses may be coming from.

It can help compare expected yield, pre-harvest loss, header loss, combine loss, cleaning loss, total bushels lost, value loss, net harvested bushels, and net crop value.

What your result means

Your result shows estimated harvest loss per acre, total bushels lost, harvest loss percent, crop value loss, expected production, net harvested bushels, marketable bushels, grain weight, harvest costs, hauling costs, drying costs, gross value, and net value. These are estimates based on the values you enter.

Harvest loss formulas

Frequently asked questions

How do you calculate harvest loss?

Add pre-harvest loss, header loss, separator loss, cleaning loss, and other loss per acre. Then multiply by harvested acres to estimate total bushels lost.

How do you calculate harvest loss percentage?

Divide total bushels lost by expected production, then multiply by 100 to estimate harvest loss percentage.

How do you calculate harvest value loss?

Multiply total lost bushels by the adjusted crop price per bushel. This estimates the dollar value of crop lost during harvest.

What causes harvest loss?

Harvest loss can come from lodged crop, ear or pod shatter, header settings, travel speed, rotor or cylinder settings, fan speed, sieve settings, field conditions, and operator adjustments.
