Chargeable Weight Formula:
| From: | To: |
Chargeable Weight (CW) is the greater of either the Actual Weight (AW) or the Volumetric Weight (VW) of a shipment. It is used by freight carriers to determine shipping costs, as lightweight but bulky packages take up more space than their weight suggests.
The calculator uses the standard formula:
Where Volumetric Weight is calculated as:
Explanation: The divisor 166 is the standard volumetric factor for inches/pounds used in the shipping industry to convert volume to equivalent weight.
Details: Accurate chargeable weight calculation is essential for proper shipping cost estimation, avoiding unexpected charges, and optimizing packaging to minimize shipping expenses.
Tips: Enter package dimensions in inches and actual weight in pounds. All values must be positive numbers. The calculator will determine both volumetric weight and the final chargeable weight.
Q1: Why is chargeable weight important in shipping?
A: Carriers charge based on which weight is greater - actual or volumetric - to account for both weight and space utilization in their vehicles.
Q2: What is the 166 divisor based on?
A: The divisor 166 represents the density standard (166 cubic inches per pound) that carriers use to equate volume to weight for pricing purposes.
Q3: Do all carriers use the same volumetric divisor?
A: While 166 is standard for inches/pounds, some carriers may use slightly different divisors. Always check with your specific carrier for their exact calculation method.
Q4: How can I reduce my chargeable weight?
A: Use more compact packaging, remove unnecessary void fill, or consider breaking large shipments into multiple smaller packages if volumetric weight is driving costs.
Q5: Is this calculation used for international shipping?
A: Yes, the chargeable weight concept is used globally, though the specific volumetric divisor may vary by region and measurement system (inches/pounds vs centimeters/kilograms).
