An 80% discount on LTL shipping sounds like a great deal. It might not be.
A shipper boasting “I have an 80% discount” may be paying more than a shipper with 60% off a tighter tariff. Always compare net rates per CWT — cost per hundred pounds — not raw discount numbers.
This is one of the most consistently misunderstood aspects of LTL pricing — and it is costing businesses real money on every shipment. To understand why, you need to understand what a base tariff actually is and how the CzarLite benchmark makes carrier comparisons meaningful.
What a Base Rate Tariff Actually Is
A rate base is the foundational pricing model that carriers use to determine the cost of moving your freight. Think of it like the MSRP for LTL shipping — it tells the carrier how much to charge before any discounts, fuel surcharges, or accessorial fees are added.
Every LTL quote starts with a base rate. The carrier looks up the rate for your origin-destination pair, freight class, and weight. That rate — expressed in dollars per hundredweight — is the starting point. The discount comes off that starting point.
Rates for the same lane can vary from tariff to tariff. A tariff published by a regional carrier may reflect better rates on short-haul lanes than long-haul. A national carrier’s tariff may reflect better rates on long-haul lanes than short-haul.
Two carriers can quote the exact same lane with the exact same freight class — and produce wildly different invoices — simply because their base tariffs are inflated at different rates.
What CzarLite Is and Why It Matters
Without a neutral, standardized pricing foundation, it is impossible to accurately and reliably judge myriad shipping rates. CzarLite is the most widely used neutral LTL base rate for pricing agreements in North America.
CzarLite reflects the analysis of 116.8 million freight bills from 33 of the largest LTL carriers — a data set unique to SMC3. It serves as an LTL pricing benchmark for thousands of successful shipper, carrier, and logistics service provider pricing agreements, representing billions of dollars in annual managed transportation spend.
In practice, many carriers quote discounts off CzarLite. While carriers set their own prices, most use SMC3 rates as a reference point, quoting discounts off the base rate. CzarLite is the most widely used benchmark — rates are expressed as discounts off CzarLite, meaning a 72% discount means you pay 28% of the published rate.
The CZAR-B tariff is a related benchmark used by many regional and national carriers alongside CzarLite for pricing agreements. These public tariffs set a starting price — they are never what a shipper actually pays. What you truly pay is the tariff base rate less a negotiated percentage discount.
The Math Behind the Illusion
Here is a concrete example of how the same discount percentage produces very different real costs.
Carrier A prices a 500-pound Class 70 shipment from Chicago to Los Angeles at $200 per CWT off their proprietary tariff. After a 70% discount, you pay $30 per CWT — or $150 total for the linehaul.
Carrier B prices the same shipment at $120 per CWT off a tighter tariff. After a 55% discount, you pay $54 per CWT — or $270 total for the linehaul.
Carrier A had the bigger discount and the lower bill. Carrier B had the smaller discount and the higher bill. The discount percentage told you almost nothing useful.
A 70% discount sounds generous — until you realize that 70% is being taken off a bloated base rate. You would not shop for a car based on percentage off MSRP without knowing the sticker price. The same logic applies here.
What You Should Compare Instead
The only number that matters is the net rate — the actual dollars per hundredweight you pay after the discount is applied. Everything else is context.
Do not just negotiate discount percentages. Ask for net rate quotes so you can compare actual costs across carriers regardless of their base tariff. Discounts often do not apply to accessorials. If you frequently need liftgate or residential delivery, negotiate those rates separately.
When evaluating a new carrier or renegotiating an existing contract, ask three questions. What base tariff does this quote use — is it CzarLite, CZAR-B, or a proprietary tariff? What is the net rate per CWT on my highest-volume lanes? And what accessorial charges apply that are not covered by the discount?
CzarLite empowers shippers to negotiate transportation spend using a consistent base rate across carriers to ensure total pricing visibility, quickly evaluate the impact of carrier rate adjustments and discounts, and streamline LTL rate negotiations by reducing or eliminating the need for ambiguous discount structures.
The Accessorial Layer That Changes Everything
Even a correctly benchmarked net linehaul rate is only part of your actual invoice. Accessorial fees can add 20 to 60% to a base shipment cost if not anticipated and negotiated.
Fuel surcharges update weekly. Residential delivery, liftgate, inside delivery, and redelivery charges vary by carrier. A net rate comparison that ignores accessorials is still an incomplete picture.
The most reliable way to compare carrier pricing is to model your actual shipment history — including the accessorials that regularly apply to your freight — under each carrier’s tariff and discount structure. That comparison produces a true cost-per-shipment number that discount percentages alone can never give you.
How Jansson LLC Helps U.S. Shippers Navigate LTL Pricing
Understanding base tariffs, CzarLite benchmarking, and net rate comparisons takes experience and most shipping teams do not have the bandwidth to conduct that analysis on every lane they manage.
Jansson LLC is a Landstar freight agent with access to a nationwide carrier network providing U.S. businesses with LTL routing options, carrier selection, and freight coordination across multiple lanes and regions.
Through the Landstar network, Jansson helps U.S. businesses compare carrier pricing on an apples-to-apples basis, identify where their current LTL spend is higher than it should be, and build freight strategies that are based on net cost rather than headline discount percentages.
