About this tool

Runs entirely in your browser: A quick invoice total builder for freelancers and small studios.

Add any number of line items, apply a tax rate and an optional discount, and see the running subtotal, tax, and grand total update as you type. It handles the arithmetic that spreadsheets make fiddly and calculators make error-prone.

Nothing is stored or sent — it is a calculator, not an invoicing account.

How to use it

  1. Add a line for each item: description, quantity, and unit price.
  2. Set the tax rate and any discount.
  3. Read the subtotal, tax, and total; copy the figures into your invoice.

Frequently asked questions

Can I use any currency?

Yes. Enter a currency code and the numbers are formatted with it. The math is currency-agnostic.

Is the tax calculation right for my country?

It applies a single tax rate to the subtotal. If your jurisdiction has compound taxes or per-item rates, treat the result as an estimate and confirm locally.

Does it save my invoices?

No. It calculates a total and forgets it when you close the tab. Use it alongside your normal invoicing, not instead of it.
