What the item price leaves out: reading an order total line by line

The six lines that build an order total, in the order they appear

A listed item price is the first of six lines, not the total. They arrive in a fixed order across two payment stages, and the last two land only after the parcel has been packed and weighed, which is 8 to 12 days after you paid for the item. The table below names all six, with the trigger that creates each one.

Two of the 6 lines are conditional and appear only sometimes: a payment processing charge and, where the currency is converted, a spread between the reference rate and the rate applied. No published figure for either was found while writing this note, which makes them the two lines to ask about in writing rather than estimate. The [cost](/table/cost/) page holds the longer list of lines seen across operators.

What moves each line: weight, declared value, or nothing at all

Freight is the only line that reacts to the shape of your parcel, which makes the chargeable weight calculation the highest-leverage number in the whole total. Chargeable weight is the greater of the actual weight and the volumetric weight, and volumetric weight comes from the carton dimensions divided by a divisor printed on the carrier card. A carton of 40 × 30 × 25 cm is 30,000 cm³; at a 6,000 divisor that is 5.0 kg billed against contents weighing 4.2 kg.

Value-driven lines behave differently. Duty and import tax in most systems are assessed on the declared value, so removing 60 units of item value moves those lines and does nothing at all to the freight line. The [duty-estimate](/rig/duty-estimate/) tool exists to keep the two effects apart, because a change that lowers one often raises the other.

• Weight-driven: international freight, and any repack charge that scales with parcel size
• Value-driven: duty and import tax, and any percentage-based line applied to the item subtotal
• Per-order: service charges and minimum charges, which stay the same whether the parcel holds one item or four
• Per-event: handling charges for work you requested, which appear once and do not scale

Shares of the total inside a single worked basket

To see which line dominates, take one basket and give every line a number. The amounts below are invented for the arithmetic — they are not rates from any operator — and the divisor is the 6,000 used above. Item 300, domestic delivery 15, service 45, freight 260 for 5.0 billed kg, handling 20. Total: 640.

Rounding leaves 0.1 of a point unassigned, which is the honest amount of precision a five-line split deserves. The useful reading is the gap between 46.9% and 40.6%: on a parcel of this shape, freight is close enough to the item line that a wrong guess about weight costs more than a wrong guess about which seller to use.

Change the mix and the ranking flips. Halve the item value to 150 with the same 5.0 kg parcel and the item line falls to 30.6% of a 490 total while freight rises to 53.1%. That reversal, not any single rate, is the reason a haul of cheap heavy goods behaves nothing like a haul of expensive light ones.

Which lines give way when you push on them

• Remove shoe boxes and retail packaging before the parcel is sealed; a pair of boxes is often 0.3 to 0.5 kg of the billed weight
• Ask for a repack into the smallest carton that fits, because the volumetric number follows the carton and not the contents
• Split a heavy outlier into its own parcel only after comparing two quotes, since a second parcel carries its own minimum charge
• Order four items in one basket rather than four baskets, which collapses four per-order charges into one
• Drop one item at the QC stage rather than after shipping, when the only remaining lever is the return route

Three of those 5 actions touch weight, and weight is the only line under your control after the item has left the seller. The [chargeable-weight](/rig/chargeable-weight/) rig does the division for a carton you measure yourself, and the [pay-freight](/steps/pay-freight/) step is the last moment at which the number can still be argued with, because after that payment the parcel is sealed and priced.

1 action looks promising and is not: cutting declared value to lower duty. Where a system assesses tax on declared value, an understated figure creates a mismatch between the invoice, the parcel and the payment record, and that mismatch is visible to whoever opens the box. The saving is on the duty line only; the risk lands on the whole parcel.

The same basket after three of the five moves

Apply three moves to the invented basket: drop the 60-unit item, repack from a 5.0 kg to a 4.4 kg billed weight, and keep every other line as it was. The per-kg figure stays at the same invented 52 for 5.0 kg, so freight becomes 228.8 and the total becomes 548.8.

Two things stand out in that column. The freight cut of 12% produced a smaller saving than the item cut, yet it is the one you can make without giving anything up — the item cut removes an object from your life. And the two per-order lines, 65 between them, did not move at all, which is why a smaller basket does not shrink every line proportionally.

A 4th move, choosing a slower lane, changes the rate rather than the weight, and the rate belongs to the carrier card. Compare the two quotes on the card before paying, because a 6-line breakdown stops being useful the moment a lane change is worth more than an hour of repacking. Ask both quotes for the same parcel: a quote written for 4.4 kg describes the box you will actually send, while a quote for 5.0 kg describes a parcel you no longer have, and the 0.6 kg between them is where the comparison usually goes wrong.
