Sales Tax Calculator guide

Add tax to a price or extract tax from an inclusive total, for any tax rate — clear net, tax and gross figures — or total up an itemised list of individual prices first. Free and instant.

How to use this tool

  1. Enter Price or inclusive total, Tax rate (%), Price includes tax?, Itemised price list.
  2. Change a value to update the results and illustration. Check any validation message before using the output.
  3. Copy the results or download CSV. Reset restores the example values.

A worked example

A price of 100 excluding 10% tax becomes 110. An inclusive total of 110 at 10% contains 10 tax and 100 net. With the itemised list on, individual item prices you add as rows are totalled into the price automatically.

Frequently asked questions

How should I interpret the illustration?

It is a visual aid, not a replacement for the numeric output. Some charts compare values with different units, and those magnitudes are not directly comparable.

Can I use the result without checking the inputs?

Check units, signs, assumptions and rounding first. The tool cannot know whether the values you enter describe the real situation correctly.
