Use this VAT calculator to add tax to a price before VAT or to work backward from a total price including VAT. It is useful for invoices, ecommerce prices, quotes, freelance work, accounting checks and everyday business calculations. Enter the amount, choose a preset VAT rate or enter a custom one, and instantly see the VAT amount, the price including tax and the equivalent pre-tax amount.
VAT (Value Added Tax) is a consumption tax applied to goods and services at each stage of production or distribution. In France, the standard rate is 20%, with reduced rates of 10%, 5.5%, and 5% for certain goods and services.
To calculate VAT on a price excluding tax: VAT Amount = Price HT × (Rate / 100). For example, for €500 at 20%: VAT = 500 × 0.20 = €100. Total incl. VAT = €600.
To extract VAT from a TTC price: Price HT = Price TTC / (1 + Rate/100). Then VAT = Price TTC − Price HT. Example: €1,200 TTC at 20%: HT = 1200/1.20 = €1,000. VAT = €200.
In France: 20% (standard rate — most goods and services), 10% (restaurants, renovations, passenger transport), 5.5% (food, books, cultural events), 5% (accommodation for people with disabilities), 0% (certain exempt activities).

The net price is the amount before tax, the VAT amount is the tax added on top, and the gross price is the total including VAT. In short: gross price = net price + VAT.
Formula: VAT Amount = Price (excl. VAT) × VAT Rate / 100 | Total (incl. VAT) = Price (excl.) + VAT Amount | To extract VAT from a total: VAT = Total − (Total / (1 + Rate/100))
Example: A product costs €1,000 excl. VAT with a 20% rate. VAT = 1,000 × 20% = €200. Total incl. VAT = €1,200.
A VAT calculator is useful whenever you need to move quickly between pre-tax and tax-inclusive prices. Typical cases include preparing invoices, checking supplier quotes, updating ecommerce product prices, comparing business costs, or reviewing accounting entries before sending documents to a customer.
It is also helpful when you work across several products or countries and need to test different rates. Even when the rate is known, mistakes often come from starting with the wrong base price, so a dedicated calculator helps confirm whether you are adding tax to a net amount or extracting tax from a gross amount.
The most common mistake is applying the VAT rate directly to a gross amount when you actually need to extract the tax portion. Another frequent error is forgetting that reduced rates may apply to certain products or services, while the standard rate applies to most others.
For business users, it is also important to distinguish commercial pricing from legal compliance. A calculator helps with the arithmetic, but you should still confirm the applicable rate and any local rules for invoicing, exemptions, or cross-border sales.
