Two of the numbers that decide what an LTL shipment costs — density and freight class — are easy to get wrong and expensive when you do. These calculators get you both in seconds, with no sign-up and no email wall. Run the numbers here, then send us the lane for a real quote.

[ 02 working tools ]Freight density calculator Calculator
Enter length, width, height, and weight to get your shipment’s cubic feet and density (PPCF) instantly. Density is the single biggest driver of an LTL rate — know it before you book.

Turn those same dimensions into an estimated NMFC freight class using the standard 18-band density scale — the classification that LTL carriers price against.

An LTL carrier doesn’t price your freight by what it is — it prices it by how much trailer space it takes up relative to its weight. That’s density: weight divided by cubic feet. Density (along with stowability, handling, and liability) sets your NMFC freight class, a code from 50 to 500 that every LTL carrier rates against. A denser shipment is cheaper to move, so it lands in a lower class; a light, bulky one fills more trailer for less weight and classes higher.
Getting the class wrong is the number-one source of surprise LTL charges — the carrier reweighs and reclasses your freight at the dock, and the bill comes back higher than the quote. These two tools let you check your own numbers up front. They’re estimates: the final NMFC item code also depends on commodity, handling, and liability, which is why a real person on our team confirms the class on every quote so the number you’re given is the number you pay. Start with the density calculator, then run the class lookup.
