Three calculators for the CNCartGo route
A cost stack, a freight estimator and a deadline clock. They use CNCartGo's published rules and the calculator answers we recorded on 24 October 2026.
Which calculator answers which stage
Here is how to use the calculator set. Each tool answers one question you will have at a specific stage. Before the first checkout: what will this cost in total? Before building the parcel: which line, and will the box bill by size? After In Stock and after delivery: when do my windows close? None of the tools needs an account, and nothing you type leaves your browser.
Siding clock: when each CNCartGo window shuts
Enter the shipment date and the date you confirmed receipt to get the after-sales window; the In Stock clock is on the warehouse page.
Freight estimator and cost stack
A worked example shows how the pieces fit. Say you want the two canvas pairs from the sneakers shelf and the cat-ear beanie, about USD 13.70 of goods, sent to the United Kingdom. The cost stack puts the service fee at the 15 per cent tier, so roughly USD 2.06, plus whatever the sellers charge to reach Guangzhou. If the three items pack to one kilo or less, the estimator shows the Royal Mail general goods line at USD 18.66 for one kilo on our test day. Freight is the biggest single cost in that order, which is normal for cheap, light goods and the reason to fill a parcel before paying the second checkout.
The freight estimator lists the lines the official calculator returned for ten countries at four weights, and works out size-based weight from your box. The cost stack applies the right service tier and adds yuan extras. Prices move; when the official calculator and our recorded answer differ, the official one is current.
