Landed Cost

One shipment. Every bill split by what drives it, then the cost per unit you sell.

Split by weight for air, parcel and truck freight, value for brokerage, insurance and a duty bill at one rate, units for a flat per-unit charge. The Excel file adds volume for ocean freight and a duty rate per line. Sample shipment is made up.

  1. What arrived, at what it cost

    One row per SKU: units received and the supplier's unit cost. Add a weight per unit if anything will be split by weight.

  2. One row per bill

    Freight, duty, the customs broker, insurance, a labeling charge. Each third-party bill keeps its own row, so the sheet matches the invoices you will be asked for.

  3. Split each bill by what drives it

    Weight for air, parcel and truck freight. Value for brokerage, insurance and a duty bill at one rate. Units for a flat per-unit charge. The Excel file adds volume and a duty rate per line.

  4. The cost to put on the product

    Line value plus its share of every bill, divided by units. This is the cost your cost of goods sold should use when the unit sells.

  5. Every dollar accounted for

    Landed total minus the goods and every bill. It must be 0.00. If it is not, a bill was split by a basis that is empty, such as weight with no weights typed in.

Run this in SKU.io

Landed cost on the purchase order

In SKU.io each freight, customs, duty or brokerage invoice is a landed cost bill on the purchase order, and you choose how it spreads across the lines. Each product's per-unit cost goes up to match, so the FIFO cost layers created at receipt and the COGS recorded at each sale both carry it.

Why the split matters more than the formula

The landed cost formula is easy: what you paid the supplier plus every bill that got the goods to you, divided by the units. The hard part is the split, because one freight bill covers a container of different products. Most tools split everything by value. That is the wrong default for anyone who imports mixed shipments.

The sample in this sheet shows it. One air shipment of yoga mats, band sets and foam rollers, with $1,380.00 of freight. Split by weight, the mats take $720.00 of it, because they are 360 of the 690 kilograms. Split by value they would take $613.33, and the band sets, which weigh almost nothing, would carry $147.22 more than their share. Each wrong share goes straight into the margin you read on that SKU.

When I would use the sheet, and when the calculator

For a quick answer on one shipment, the landed cost calculator does it in the browser. Use this sheet when you want the working kept with the purchase order, when lines pay different duty rates, or when ocean freight should be split by volume. Once you are doing it on every purchase order, the bills belong on the PO itself, where they reach cost of goods sold without being copied anywhere.

What belongs in landed cost, how to split each kind of bill and the mistakes that make COGS wrong are in the landed cost guide. Whether landed cost is capitalized is check 6 of the ecommerce accounting standards checklist. If your POs still live in a spreadsheet, the purchase order template has freight and duty on their own rows too.

Questions people ask

How do you calculate landed cost per unit?

Landed cost per unit is the line's supplier cost plus its share of every freight, duty, insurance and fee bill, divided by the units on the line. In this sheet's sample, the yoga mats cost $2,400.00 from the supplier and take $954.67 of the shipment's bills, so 300 mats land at $11.18 each.

Should freight be split by weight or by value?

By weight for air, parcel and truck freight, and by volume for ocean freight, because that is how carriers bill. In the sample, $1,380.00 of air freight split by weight puts $720.00 on the yoga mats. Split by value it would put $613.33 there, and the light band sets would carry $147.22 more than their weight justifies.

How should a duty bill be split?

By value when every line pays the same duty rate. When rates differ, split it by each line's value times its own rate, so a duty-free line carries none of it. The Excel file has a duty rate column for that.

What costs belong in landed cost?

The supplier's price, freight to you, cargo insurance, customs duty and tariffs, broker and filing fees, inbound fees to get stock into a marketplace warehouse, and labor that makes the sellable unit. Shipping to customers, selling fees, storage and advertising do not.

What is the difference between this and the landed cost calculator?

The calculator works out one shipment in your browser. This spreadsheet is the file you keep with the purchase order: up to 30 lines and 5 bills, a volume basis for ocean freight, a duty rate per line, and a check that the bills were fully spread.
