A field guide to cross-border paymentsSupplier payments, FX and import costs
METHODOLOGY / SHOW THE WORK

Where the numbers come from

Some figures come from official sources; others are calculations or assumptions you enter. Here is how to tell them apart before using a result to plan a payment.

01 / Source material

Customs and regulatory explanations link to the relevant authority. For payment rules, we use official rule publishers or government guidance. Provider comparisons draw on the providers’ published information and state the limits of what it covers.

Checklists and suggested workflows are editorial guidance, not instructions issued by a regulator. Eligibility, prices, duties, and operating requirements can change. Check the linked source for your transaction and the date that applies.

02 / Historical FX data

The FX page shows a historical window covering 2–10 January 2025. Each observation has a date and source. The dataset is not a live feed, a forecast, or a rate you can transact at.

Rates are shown as foreign-currency units per US dollar. Values originally published as US dollars per euro are inverted to use the same convention. The dataset keeps the original values and the conversion. We do not fill missing days by interpolation, and a publication date does not replace the observation date.

The Federal Reserve and ECB can observe rates at different times and use different methods. A difference between their figures is not a tradable spread. VND is not included in this dataset. For that currency, supply a dated quote; do not fill the gap with an invented value.

03 / Landed-cost calculation

The calculator estimates landed cost in USD for a US import. It calculates from the inputs you enter. The starting figures are examples, not market rates, tariffs, or shipment quotes.

The calculationGoods in USD = foreign invoice amount ÷ FX rate
FX cost = goods in USD × separate markup %
Estimated duty = customs value in USD × (base duty % + additional duty %)
Total = goods + FX cost + freight + insurance + duty + brokerage + customs fees + other costs + transfer fee
Cost per unit = total ÷ units entered

Check the inputs before using the total

  • Enter the rate as units of the invoice currency per US dollar. Use 1 for a USD invoice.
  • A separate FX markup adds a percentage cost; it does not change the rate you entered. Use zero if the customer rate already includes that margin.
  • Customs value is editable and separate from both the invoice amount and total landed cost. Check required additions and exclusions against the applicable rules and with your broker.
  • Check what each supplier or forwarder quote includes so that freight, insurance, or other bundled charges are counted only once.
  • Enter base and additional ad valorem duty percentages separately. Put any verified specific duties, taxes, or other customs charges in the customs-fees field. The calculator does not classify your goods or identify the charges for you.
  • Marketplace fees after warehousing, financing, returns, and selling costs are excluded unless you choose to add them under other costs.

Displayed results are rounded; the calculation keeps the underlying precision. Rates and unit counts must be greater than zero. Cost amounts and percentages must be finite, non-negative numbers. Check the scope and assumptions before using the total.

04 / Maps and provider comparisons

The map shows market pairs schematically. Its lines are not vessel routes, guaranteed payment paths, or transit-time commitments. Each guide explains the direction of the goods and the payment, and who needs to confirm the transaction details.

Comparisons summarize published features and questions to ask a provider. They do not establish that your business is eligible, that every currency works on every route, or that the listed providers are your only options.

05 / Worked examples and corrections

Project pages use illustrative scenarios. Invented amounts, rates, and dates are labeled, and no customer outcome is claimed. Historical observations are identified separately from worked calculations.

If you spot a possible error, note the page, the statement, the relevant date, and a public source. You can prepare an inquiry draft on the contact page, but the form does not send it.

Pre-shipment checks

Check the order before it ships.

Review the invoice, bank details, documents and costs before releasing the balance.

Start with “China”, “FX” or “letter of credit”.
