Freight Class Calculator

Freight class calculator finds the NFMC freight class of your cargo.

With this freight class calculator, you will never be surprised by freight quotas again. It is a tool that, basing on the pallet's weight and dimensions, calculates the class of your freight in a blink of an eye. If you are new to do business and have no idea how to calculate the freight class, have no worries - we will explain it to you in no time at all!

What is the freight class?

Freight classes are a way to categorize any shipment, basing on its dimensions and weight. They are directly correlated to the density of the shipment: the denser your cargo is, the higher the class. Typically, higher classes are charged less per pound, so you should make sure that your cargo is as compact as possible.

Our freight class calculator is based on the American NFMC (National Motor Freight Classification).

How to calculate freight class?

  1. Begin with determining the dimensions of one pallet in your shipment. For example, we can assume that you are shipping boxes that are 3 ft x 4 ft x 5 ft in size.
  2. Weigh the pallet. Let's assume that it weighs 260 lbs.
  3. Calculate the volume of your pallet by multiplying its dimensions by each other. In this case, 3 * 4 * 5 = 60 cu ft.
  4. Divide the weight by the volume of the cargo to calculate the density: 260/60 = 4.33 lb/cu ft.
  5. Compare this value with the table above to find the appropriate freight class. In this case, your shipment belongs to freight class 200.

Further steps

Now that you know the freight class of your cargo, you should take a closer look at it. Maybe you'll be able to optimize it? Here are some suggestions to get you started:

  • If the cargo density is just below the upper limit of the current freight class (for example, 7.98 lb/cu ft), adding just a bit of weight from the pallet will result in a higher class and, subsequently, in lower freight rates. It is possible that you will have to pay less in the end!
  • Alternatively, if the density is almost equal to the upper limit of the freight class, you can consider compacting your shipment a tiny bit more. Reducing the volume by a few cubic inches will result in a more economic freight class.
  • You can also check out the CBM calculator to calculate the total volume of your cargo.

If you open the advanced mode of our fright class calculator, you will be able to input the freight rate per unit weight. The calculator automatically determines the freight cost. Note that it doesn't take into account any additional payments such as insurance or fragile cargo fees - it is simply the lowest possible sum you have to pay to get your cargo shipped.
