Shipping Cost Calculator for DIM Weight and Cost Per Unit

How to Calculate DIM Weight and Cost Per Unit with the Shipping Cost Calculator

Estimate shipping cost from package weight, rates, fuel surcharge, and handling. Calculate dimensional weight and landed shipping cost per unit.

DIM weight = length x width x height / divisor; billable weight = max(actual, DIM)

Test a smaller package and your contracted divisor to quantify avoidable monthly shipping cost.

Carrier divisors, rounding, zones, fuel, residential, and oversize surcharges vary by contract. Inputs and calculations stay in this browser.

DIM Weight = (L × W × H) / DIM Factor

Dimensional Weight (also called volumetric weight) is a pricing technique used by carriers that considers package size, not just actual weight.

Billable Weight is the greater of actual weight or dimensional weight. Carriers charge based on whichever is higher.

Optimization Tip: Reduce package dimensions when possible to lower dimensional weight and shipping costs.
