VAT & Sales Tax Calculator
Add VAT or sales tax to an amount, or extract the tax portion from a tax-inclusive total.
Enter your values to calculate your result.
Formula
Adding tax: Total = Amount × (1 + Rate ÷ 100) Extracting tax: Pre-Tax = Amount ÷ (1 + Rate ÷ 100)
Enter whichever tax rate applies in your situation — this calculator never assumes a specific country's rate, since VAT and sales tax rates vary by jurisdiction and change over time. If your amount is already tax-inclusive (common with VAT receipts), choose 'extract the tax' to see the pre-tax amount and the tax portion.
Example
A $100 pre-tax amount with a 15% tax rate gives a $15.00 tax amount and a $115.00 total. A $115 tax-inclusive total at the same 15% rate extracts back to a $100.00 pre-tax amount.
Frequently Asked Questions
What tax rate should I use?
Use the VAT or sales tax rate that applies to your specific purchase and jurisdiction — this calculator doesn't assume any particular country's rate, since rates vary and change over time.
Why are both pre-tax and total amounts always shown?
Showing both, regardless of which direction you entered, makes it easy to see the full picture without needing to run the calculation twice.
