Shipping Calculator FAQ
How does the Shipping Cost Calculator work?
Enter your origin ZIP code, destination ZIP code, and package weight. Our calculator compares real shipping rates from USPS, UPS, and FedEx and displays them side by side so you can find the cheapest or fastest option.
Is this shipping calculator really free?
Yes. Our shipping rate comparison tool is completely free to use. There are no hidden fees, premium tiers, or account requirements for basic rate lookups.
What carriers do you compare?
We compare rates from three major carriers: USPS (including Priority Mail, Ground Advantage, and First-Class Mail), UPS (Ground, Next Day Air, 2nd Day Air), and FedEx (Ground, Home Delivery, Express). This covers both domestic and international shipping services.
Can I compare international shipping rates?
Yes. Enter a destination country instead of a ZIP code to see international shipping rates from all supported carriers. We support shipping to over 200 countries worldwide.
How accurate are the shipping rates shown?
Our rates are sourced from official carrier rate tables and updated regularly. Rates shown are retail (list) prices before any negotiated discounts. Actual costs may vary based on surcharges, dimensional weight, or special handling requirements.
What is dimensional weight?
Dimensional weight (DIM weight) is a pricing method that considers package size in addition to actual weight. Carriers charge the greater of actual weight or dimensional weight. Large but lightweight packages may be priced by their dimensions rather than what they weigh.
