I built a shipping calculator in a spreadsheet in the mailroom where I worked, because comparing carriers meant walking between workstations. Now it's an app — same idea, one screen.
Enter weight, dimensions, and quantity, and it prices your shipment across UPS, FedEx, USPS, DHL Express, and OnTrac — cheapest first, with a full report. It handles dimensional weight and bulk quantity pricing, domestic and international, for parcels and mailings of any size.
Rates from live carrier website checks on Nov 13, 2026 — estimates, not live quotes. This app does not fetch live prices; confirm the final price with the carrier before you ship.
