About this VAT calculator

This VAT calculator helps you add or remove VAT for any price, tax rate, and quantity. It shows a clear breakdown of net amount, tax amount, and gross amount per unit and in total, so you can quickly check quotes, invoices, or price lists.

Net vs. gross and the formulas

When you add VAT: gross = net × (1 + rate/100) and tax = gross − net. When you remove VAT: net = gross ÷ (1 + rate/100) and tax = gross − net. The calculator applies these formulas per unit and multiplies by quantity to show totals.

Using the tool responsibly

What is VAT?

VAT (Value Added Tax) is a consumption tax charged on many goods and services in many countries. Businesses collect VAT on sales, typically reclaim VAT paid on purchases, and remit the difference to the tax authority.

VAT can have different names. For example, you may see sales tax in parts of the U.S., TVA in France, or Mehrwertsteuer (MwSt) in Germany. The basic idea is similar: a percentage is applied to the net price to arrive at the price the customer pays.

Net vs. gross prices

A net price is the amount before VAT or sales tax. A gross price is the amount after tax has been added. Many invoices and price lists show both, so it is clear what part is tax and what part is the underlying value.

  • Net amount (excl. tax) – the base price used for calculations.
  • Tax amount – VAT or sales tax added on top.
  • Gross amount (incl. tax) – the final price paid.

In this calculator you first choose whether your input amount is excluding or including VAT. The tool then calculates the missing values and shows a side-by-side breakdown per unit and for the full quantity.

Formulas used by this calculator

All calculations use simple percentage formulas:

  • Adding VAT (net ➜ gross): gross = net × (1 + rate / 100)
  • Tax amount: tax = gross − net
  • Removing VAT (gross ➜ net): net = gross ÷ (1 + rate / 100)

The same formulas apply for one item or a full order. Totals are the per-unit values multiplied by the quantity.

Typical ways to use this tool

  • Checking invoices: verify the tax amount and totals match the quoted rate.
  • Converting price lists: switch between net and gross prices for catalogs, webshops, or menus.
  • Estimating quotes: start from a net budget and see the customer-facing total including VAT.
  • Comparing countries: see how different VAT rates change the final price.

Limits, rounding, and tax rules

  • VAT math only: this tool applies a rate you enter. It does not determine which VAT rate applies to a product or country.
  • Rounding can differ: invoices may round per line, per unit, or on totals only. Small differences are common.
  • Local rules vary: thresholds, exemptions, and special schemes are not modeled here.
  • Educational use: treat results as a quick estimate, not tax, accounting, or legal advice.
