How Shipping Cost Calculation Works
The Shipping Calculator estimates shipping costs based on package dimensions, weight, origin, destination, and carrier service level. Compare rates across carriers to find the most cost-effective shipping option for your packages and parcels.
Formula
Dimensional Weight = (Length x Width x Height) / Dimensional Factor
Key Features
- ✓Estimate costs based on weight and dimensions
- ✓Compare rates across multiple carriers
- ✓Support for domestic and international shipping
- ✓Factor in dimensional weight pricing
Pro Tip
Carriers charge by the greater of actual weight or dimensional weight. Dimensional weight = (L x W x H) / dimensional factor (usually 5000 for cm or 139 for inches). Use the smallest possible box to avoid paying for air.

When to use this calculator
- Before offering free shipping so you know the margin trade-off.
- When package size, carrier, or destination changes are affecting conversion or profitability.
- When you need to compare store platforms with different shipping and fulfillment workflows.
Worked example
A 2-pound parcel in a 12 x 10 x 4 inch box might ship for about $8 to $10 with standard ground delivery, but a slightly larger package can trigger dimensional pricing and push the cost materially higher. That is the difference between a viable free-shipping offer and a hidden loss.
How to interpret your results
Treat shipping as part of unit economics, not a separate afterthought. If delivery cost wipes out too much margin, revisit packaging, threshold offers, product bundles, or carrier choices before you touch ad spend.
