Landed cost before resale price

The box price is only the first line of your cost. Sellers who price from the sticker get surprised at the border, at the platform fee statement, and at the post office. Sellers who price from the full stack know their profit before they order.

Five cost lines

Illustrative calculation

Say a box costs ¥6,000 and your share of freight on a 20-box order is ¥400. Duty and VAT add ¥900 on arrival, so it lands at ¥7,300. If it sells for the equivalent of ¥9,500 and your platform plus payment fees take ¥1,300 you keep ¥900 per box — before your packing time.

Run the same arithmetic with your real rates before every order. The point is not these numbers; it is that every line was known before the box was bought.

CHECK BEFORE ORDERING

Calculate landed cost per box before ordering, then add the margin required by your store.
