CWT rate calculator
Calculate weight in hundredweight × your entered rate, with an optional minimum charge.
Shipment Weight & Tariff Rate
Calculation & comparison
Calculating...Enter the applicable weight and rate after any tariff discount. This tool does not select weight breaks, calculate deficit weight or determine your contract rate. The $0.05 comparison threshold is a review aid.

How is Freight Hundredweight (CWT) Calculated?
Freight hundredweight (CWT) base rate is calculated by dividing total shipment weight in pounds by 100, then multiplying by the quoted tariff rate per hundredweight. Formula: (Weight in LBS ÷ 100) × CWT Rate = Base Linehaul Amount. If the calculated freight is lower than the carrier's Absolute Minimum Charge (AMC), the minimum floor applies.
Step-by-Step CWT Calculation Example
Assume a shipment billed at 1,425 LBS with a quoted tariff rate of $6.50 per CWT and an AMC of $75.00:
- Convert total weight to hundredweight units:
1,425 LBS ÷ 100 = 14.25 CWT - Multiply by CWT tariff rate:
14.25 × $6.50 = $92.625 - Apply commercial half-up rounding:
$92.63 Expected Base Linehaul - Evaluate against carrier minimum charge:
$92.63 > $75.00 AMC Floor (CWT applies)
Choosing the rate and rated weight
Use the weight and rate required by your carrier tariff or agreement, including the applicable weight break and discount. This calculator multiplies the values you enter; it does not look up a tariff, select a weight break or calculate deficit-weight alternatives.
Some tariffs permit rating at a higher weight break when that produces a lower charge. Compare those alternatives separately when your agreement allows it. Fuel, accessorials, taxes and other invoice charges are outside this base-freight calculation.
