Calculate grain bin capacity, bushels, cubic feet, grain weight, fill level, grain value, and storage space. Use this grain bin capacity calculator for corn, soybeans, wheat, oats, barley, sorghum, rice, and other stored grain.
Flat bottom bin:
The calculator uses bin diameter and sidewall height to estimate cylindrical grain volume.
Peak or roof fill:
Peak grain height is treated like a cone and added to the cylinder volume.
Hopper or cone bottom:
Hopper height is treated like a cone and added to storage volume when selected.
Bushels and weight:
Cubic feet are converted to bushels, then bushels are multiplied by test weight to estimate pounds and tons.
A grain bin capacity calculator helps estimate how many bushels a bin can hold and what the stored grain may weigh or be worth.
It can help compare bin size, fill level, cubic feet, bushels, test weight, shrink, handling loss, storage cost, grain value, and remaining usable capacity.
Your result shows estimated gross bushels, usable bushels, marketable bushels, cubic feet, grain weight, tons, grain value, storage cost, net grain value, reserve space, and capacity per bin. These are estimates based on the values you enter.
Estimate the bin volume in cubic feet using the bin diameter and grain height, then divide cubic feet by about 1.244 to estimate bushels.
One bushel is commonly estimated at about 1.244 cubic feet for grain volume calculations.
Multiply estimated bushels by the test weight in pounds per bushel. Divide pounds by 2,000 to estimate tons.
Reserve space helps avoid overfilling and leaves room for aeration, grain peak variation, handling differences, and safer storage management.
