Ecommerce Shipping Calculator

A shipping calculator that shows the real number before the carrier does.

If you have ever listed a product with confident pricing and then watched a dimensional weight surcharge eat the margin, or shipped a box you assumed was Zone 4 only to discover it billed as Zone 7, this app is built for you.
It is a quiet, offline-first parcel calculator for Etsy, eBay, Shopify, Amazon FBA, Mercari and Depop sellers who would rather know the truth in advance than apologise to themselves at month-end when the payouts come in.
No account to create, no carrier login required, no package data sold to anyone, and no upsell sitting between you and the answer you came for.
The whole point is that the small merchant on a kitchen-table operation gets the same dim weight visibility the giant warehouse gets.

Type the length, width, height and actual weight, choose origin and destination, and the app returns dimensional weight, billable weight and a zone-based shipping cost estimate across USPS, UPS, FedEx, DHL and a growing list of regional carriers.
A box calculator helps you fit multiple items into the right size so you stop paying for air, the margin view compares parcel cost against sale price so you can price with eyes open, and a customs estimator gives a realistic duty number for international orders before you commit to a label.
Unit conversion between lbs and kg, in and cm is one tap, presets per product or per box size mean repeat shipments take seconds, and a quick history view lets you re-run yesterday's quote when a buyer asks for one more.

The shipping rate work happens locally on your device, so this freight calculator stays usable on planes, in stockrooms and anywhere the warehouse Wi-Fi gives up at the worst possible moment.
A FedEx calculator, DHL calculator and USPS-style quote all live in the same screen, so you stop juggling three carrier websites in three tabs while a buyer waits.
Save common origin postcodes, mark which carrier you actually use for which lane, and the app remembers your defaults so a typical quote takes two taps.
Compare carrier prices side by side for the same parcel dimensions and the same shipping weight to see who actually wins this week — rates change, and the comparison view changes with them when you refresh the schedule inside the app.
Override any single fee when a carrier publishes a fuel surcharge or a peak-season adjustment before the preset catches up, and your overrides stay sticky for that specific lane until you change them back.

Widgets keep a quick-calc shortcut on the Home Screen for between-listing checks, the interface ships in 39 languages with full VoiceOver support, and nothing about your shipping weight, parcel dimensions or customer addresses ever leaves the device — exactly the kind of ecommerce tools small merchants quietly need.
Built for Etsy shop owners packing tonight's orders, eBay resellers thrifting on the weekend, Shopify operators scaling into freight, Amazon sellers fighting FBA fees, and anyone who would rather see honest shipping tools than another dashboard pretending to be one.
A package size calculator, a dim weight estimator and a parcel calculator in one calm app that respects your time and your margins.
The shipping calculator is the kind of tool you wish you had two years ago, when you first realised the headline rate on the carrier website almost never matched the number on the invoice.
Quiet, fast, focused on one job — telling you what a parcel actually costs, before the label is paid for and the box is out the door.
