Free Invoice Generator

Foreign currency invoice calculator

You price in your currency and the client pays in theirs. Enter what you need to receive and the exchange rate, and this works out the figure for the invoice. It rounds up, so the conversion never leaves you short.

What you need
The client's currency

The rate one unit of the client's currency buys in yours. The sheet prints it both ways round, so a rate typed back to front shows at once.

Cost and risk optional

The spread and any fee taken when the payment is converted.

How far the rate can fall before payment and still cover you.

Used only if you press Create this invoice, as the line it becomes.

What the foreign currency invoice calculator does not do

  • It does not look up exchange rates. Type the rate your bank or payment service would give you; the rate on a news site or a search result is usually the mid-market one, which you will not be paid at.
  • It does not predict the rate. The buffer is protection you choose, and the table shows what a move would do, not what will happen.
  • It does not handle tax. If the invoice carries VAT, GST or sales tax, add it in the invoice generator or work it out with the VAT calculator.
  • It does not keep anything. Nothing is written to your browser's storage while you use it and nothing is sent to us, so the figures are gone when you close the tab. Press Create this invoice if you need a document: the figures are handed to the invoice generator in this tab, cleared as soon as it opens, and saved there as a new invoice alongside any you already have.
