How is VAT extracted from a tax-inclusive price?

The gross amount is divided by 1 + rate/100 to find the net amount. The difference between gross and net is the included tax.

Can I enter a custom tax rate?

Yes. The quick-rate buttons are shortcuts; the rate field accepts any non-negative decimal percentage.

Does the calculator know which VAT rate applies?

No. It applies the rate you enter and does not determine jurisdiction, product exemptions, registration status, or tax liability.

About VAT calculation

Value Added Tax (VAT) or sales tax is charged as a percentage on top of a net price. This calculator works both ways: add VAT to a pre-tax amount to get the total customers pay, or extract the VAT that is already baked into a gross price to find the net and the tax portion — useful for invoices, receipts, and bookkeeping. Pick a quick rate or type your own; everything is computed instantly in your browser.
