About this tool
In the US, sales tax is set by states, counties and cities, so the combined rate can range from 0% (e.g. Oregon, Delaware) to over 10% in some cities. Check your local combined rate for accuracy.
In the UK, EU, Canada, Australia and the Gulf, prices are usually shown including VAT or GST. Use “Remove tax” to find the price before tax — useful for invoices and business expense claims.
Formulas
- Tax = price × rate
- Price before tax = total ÷ (1 + rate)
