Two calculators, built from MambaBuy's own numbers
How to use these calculators: both run entirely in your browser, a shipping calculator and a storage-and-return clock. The shipping estimate uses the one-kilogram totals MambaBuy's own freight estimator returned on 21 October 2026, scaled by weight; the storage clock applies the return and storage windows published in help articles 6847 and 7056. Neither tool talks to MambaBuy's servers or your account.
Shipping and landed-cost estimate
Ten destinations, one line each, read from the estimator on 21 October 2026; see the full shipping lines table. Real quotes change by the day and by the exact line MambaBuy assigns your parcel.
Storage and return-window clock
Where the figures come from
The shipping tool's per-kilogram rates are the cheapest line MambaBuy's own estimator returned for each destination on 21 October 2026; it rounds weight up in half-kilogram steps, matching the behaviour described in help article 6964. It does not include duties on lines that are not already marked tax and duty included, since those are charged by the destination country, not MambaBuy. The storage clock applies a flat five, ninety and one-hundred-eighty day schedule from help articles 6847 and 7056; MambaBuy's own text on the five-day window is itself ambiguous between counting from warehousing and from seller dispatch, and this tool uses the warehousing date as the more commonly cited reading.
A worked total, step by step
Say a parcel to Germany weighs 1.3 kilograms, the goods cost CN¥650, the order was placed yourself on the website rather than through staff, and payment is by PayPal. The estimator above rounds 1.3 kg up to 1.5 kg, multiplies by Germany's quoted rate of CN¥114 per kilogram to get CN¥171 in shipping, applies no agent fee since the order was self-placed, and adds a PayPal fee of roughly 3.7% of the goods value plus a flat $0.30 converted to CN¥. The total lands a little under CN¥850, before any duty the line does not already include. Switching only the payment method to account balance removes the PayPal fee entirely and is the cheapest of the three options offered here.
The same logic holds for any destination and weight; the point of the tool is to let you change one variable at a time, line, weight, payment method, manual versus self-service, and see which one actually moves the total for your own order.
