What this is Five live calculators: yarn count conversion across seven numbering systems, woven fabric weight from the construction, a container rate turned into freight per kilogram, a garment or home textile landed cost with the base duty, the United States extra layer for your origin and the VAT filled in from our duty page, and the interest cost of a payment term at your own borrowing rate, all computed on your device as you type.
How to read it Each calculator is a small form above a list of answers: type in the boxes and every answer row refreshes as you type, with the figure's name on the left and the result on the right. A row saying waiting for a number means a box above it is empty. Where the site already knows a figure it is filled in for you, and each prefill says where it came from: the freight tool starts at this week's index rate, and in the landed cost tool the duty rate, the US extra layer and the VAT fill themselves when you pick the market and the origin, the VAT staying yours to edit. Read the landed cost's first two rows before trusting its total: they state the duty rate used, the base it is charged on, and what was added for the United States. The payment terms tool starts empty on purpose: every figure in it is yours or your bank's, and none is ours to guess.
What moves it Only what you type. The outside ingredients are the base duty rate and the US extra layer in the landed cost tool, which come from the same schedule readings as our duty page, each with the date it was read, and change when a budget or a trade notice changes them.
How to use it A thirty second sanity check before the real work: whether a quoted count, weight, freight rate, landed price or credit term is even in the right neighbourhood, and which of the five numbers deserves the argument.
The trap These are planning figures. The fabric tool's allowances are assumptions, the freight tool is the ocean leg only, the landed cost uses the base duty with no preference claimed and adds only the one US layer it knows about, not the processing and harbour fees, the cotton assessment or any antidumping order, and the payment terms tool is simple interest at a rate you supply, not a bank's quote. A calculator that agrees with a quote does not replace a broker, a test report or a sealed sample.
