Landed Cost and Import Costing Calculator

Importers often set selling prices from the supplier invoice plus a rough guess for freight. The costs that arrive later (freight, insurance, clearing, port charges, bank fees, duty, breakage) quietly take the margin, and you find out when the goods are already on the shelf. This app works the real cost out first, per unit, line by line.

You enter the supplier invoice lines (quantity, unit price, optional carton size, weight, volume and duty %) and the shipment costs in any currency with your own exchange rate. The app spreads each cost over the lines by value, weight, volume, units or equally per line, works out the customs value and duty on the basis you choose, treats import VAT as recoverable, a cost or not applicable, allows for shrinkage, and shows landed cost per line and per unit in AED. Choose a target margin or markup and a rounding step and it suggests a selling price. A container tab shows how full a container is by volume and weight, against capacities you type in.

What is inside:

• Shipment, Results, Cost spread, Container fill, Settings and How it works tabs
• Several shipments kept on your device, each with its own lines and costs
• CSV import for invoice lines, JSON export and import for backups
• An invented worked example in USD and an EXAMPLE-DATA folder
• A printable A4 result sheet

Your rates, your rules: the app knows no customs duty rate, no freight rate and no fee. Every rate is a setting you type in from your tariff, your quotes and your clearing agent, so check your current rate card and your own declaration. It is not a customs declaration. It is not tax or legal advice, not an FTA-approved system, and no platform or courier endorses it.

How it differs from the spreadsheets in the catalogue: the pricing and margin workbooks start from a cost you already know. This app calculates that cost from the invoice and the shipment, with multi-line cost allocation and container fill, and runs as a single offline file.

Tested: every calculation was compared with an independent Python (Decimal) calculation on randomised cases, CSV edge cases (quotes, commas, Arabic text, byte order mark) were run through the importer, and the screens were driven in a headless Chromium browser at phone and desktop widths. It has not been tested on a real phone, in Safari, Firefox or Edge.
