How accurate are the shipping cost estimates?

These estimates are based on published rate tables and dimensional weight calculations. Actual rates may vary based on your account type, negotiated discounts, surcharges, and current fuel adjustments. We recommend using carrier websites for final quotes.

What is dimensional weight and why does it matter?

Dimensional weight (DIM weight) is a pricing technique that considers package size, not just actual weight. Carriers charge the greater of actual weight or dimensional weight. This prevents large, lightweight packages from taking up space without paying fairly.

Which carrier is cheapest for shipping?

It depends on package size, weight, distance, and speed. USPS is often cheapest for small, lightweight packages. UPS and FedEx are competitive for heavier items. This calculator helps you compare all options side-by-side.

How It Works

This free shipping calculator estimates costs based on published carrier rates, dimensional weight calculations, and shipping zones. Enter your package details to compare rates from USPS, UPS, FedEx, and DHL side-by-side.

Dimensional Weight

Carriers charge based on the greater of actual weight or dimensional weight (L × W × H ÷ DIM factor).

Zone-Based Pricing

Shipping zones are based on distance between origin and destination ZIP codes. Higher zones = higher rates.

Insurance Options

Add declared value insurance to protect high-value items. Rates vary by carrier and coverage amount.

Delivery Estimates

Transit times are estimates and may vary based on weather, holidays, and carrier service levels.

Important: These are estimated rates for comparison purposes. Actual shipping costs may vary based on account discounts, fuel surcharges, residential delivery fees, and other factors. Always verify final costs on the carrier's official website before shipping.
