Landed Cost Calculator

WHAT IT DOES

Landed Cost Calculator is a floating calculator panel that adds product price, shipping cost, customs duties, insurance, and handling fees to compute the total landed cost of an imported product. It auto-detects product price on many e-commerce pages, saving you from copying and pasting numbers. You can adjust duty rates, insurance rates, handling fees, and tax rates, and the calculator updates the breakdown in real time.

WHERE IT RUNS

This script runs on any website you visit — e-commerce sites, supplier pages, marketplaces, or any page where you need to estimate landed costs. It reads only the page you are looking at, never other tabs, bookmarks, or browser data.

HOW TO USE

Visit any product page with a price displayed. Click the Landed Cost Calculator panel button in the BotGentz extension toolbar. The panel appears at the edge of the page. If the price is detected, it automatically fills the Product Price field. If not, enter the price manually. Enter shipping cost, duty rate (percentage), insurance rate (percentage), handling fee, and tax rate. The total landed cost updates as you type. You can save your default rates — they persist across pages.

TECHNICAL MECHANISM

The calculator scans the page for price indicators using a combination of CSS selectors (like .price, .product-price, [data-price]) and regular expression matching for dollar amounts. It identifies the most representative price on the page by taking the median of all detected prices to avoid being thrown off by discounted or sale prices. The duty, insurance, and tax calculations are based on the subtotal (product price plus shipping) and are applied as percentages with real-time updates. The entire calculation runs client-side — no data is sent anywhere.

THE PANEL

The panel is a floating overlay that you can drag anywhere on the screen by its header. It remembers its position per site so it reappears where you left it. The panel can be collapsed into a small handle to get it out of the way, and snapped to the edge of the page. It can be resized to fit your workflow. Press Escape to close the panel.

PLEASE NOTE

This script requires the free BotGentz extension to run. It reads only the page you are viewing — no data is stored or transmitted. The price auto-detection works on many major e-commerce platforms but may not work on all sites. Default rates are saved locally and persist across pages. The calculator is for estimation purposes only — actual landed costs may vary based on customs regulations, exchange rates, and other factors. Sites change — the script may need updates to match new site structures.
