VAT Calculator

What this calculator does

The VAT Calculator helps you either add VAT to a net price or extract the VAT portion from a gross amount that already includes tax. It gives you the net amount, VAT amount, gross total, and the effective multiplier used in the calculation.

Add mode versus extract mode

Choose add mode when you start with a price before tax and need the final amount including VAT. Choose extract mode when you already have a tax-inclusive total and need to separate the pre-tax value from the VAT portion for reporting, quoting, or bookkeeping.

Typical use cases

• Preparing invoices and proposals for clients.
• Checking whether retail prices already include VAT.
• Separating tax from marketplace, ecommerce, or POS totals.
• Reviewing supplier bills and bookkeeping entries before posting them.

Things to keep in mind

VAT rules differ across countries, regions, and product categories, so this tool focuses only on the arithmetic. Make sure you enter the correct VAT rate for the transaction you are working on and remember that real invoices may also include discounts, shipping, or other taxes outside the VAT amount itself.
