Invoice calculator
Turn a list of invoice line items into net, VAT and gross totals, ready to send.
Invoice calculator
Paste one line item per row — name, quantity, unit price and VAT rate, separated by semicolons — and this tool builds the whole invoice: net, VAT and gross for every line, a recap grouped by tax rate, and the total due as both a number and a spelled-out amount. It's built for freelancers and small businesses who need a correct invoice total without opening a spreadsheet.
Turn on "Prices include tax" when the unit prices you typed are gross, and the tool backs out the net and VAT instead of adding them. Each line carries its own VAT rate, so an invoice mixing a 20% service with a 10% reduced-rate item totals correctly in one pass. Add a per-line discount by appending it after the VAT rate — "10%" or a fixed amount both work — or apply one to the whole invoice with the document discount option, which spreads proportionally across every tax rate. Shipping is added at its own VAT rate, and the total can be rounded to a whole currency unit for cash-friendly invoices, with any adjustment shown as its own line.
A line that doesn't match the "name;quantity;price;rate" shape — a header row, a note — passes through untouched and counts as skipped rather than breaking the calculation. Currency and number formatting follow the site's language, and the currency code is yours to set: any ISO 4217 code like USD or GBP works alongside the default EUR. Choose plain text instead of a table when pasting the result into an email.
Everything runs in your browser — line items and totals are never uploaded, so it's safe to use with real client invoices. Copy the result, download it as a .txt file, or send it back into the input to adjust a line and recalculate.
