How to Calculate VAT — Formula, Examples & Free Calculator

VAT (Value Added Tax) is an indirect consumption tax assessed on the value added to goods and services at every stage of production and distribution. Unlike a traditional retail sales tax, which is levied only at the final point of sale to the consumer, VAT is collected in fractional payments across the entire supply chain. Every registered business along the chain calculates VAT on its sales (output VAT) and deducts the VAT paid on its business purchases (input VAT), remitting only the net difference to the tax authority. For end consumers, VAT is included directly in the final purchase price. In the European Union, VAT rules are harmonized by the EU VAT Directive (2006/112/EC), but each member state sets its own standard and reduced rates within statutory minimums. Standard rates range from 17% in Luxembourg to 27% in Hungary.

Calculating VAT involves three fundamental formulas depending on whether you are adding tax to a net price, extracting tax from a gross invoice, or calculating only the tax portion. ════════════════════════════════════════════════════════ ADDING VAT (Net → Gross): Formula: Gross = Net × (1 + VAT rate) Example: €100 × (1 + 0.19) = €119 (Germany 19%) REMOVING VAT (Gross → Net): Formula: Net = Gross ÷ (1 + VAT rate) Example: €119 ÷ 1.19 = €100 (Germany 19%) VAT AMOUNT ONLY: Formula: VAT Amount = Net × VAT rate Example: €100 × 0.19 = €19 ════════════════════════════════════════════════════════ Mathematical note: When calculating VAT from a gross amount, you must NEVER multiply the gross by the tax rate. Multiplying €119 by 19% yields €22.61, which is incorrect. Because the rate was originally applied to the net base, you must divide by (1 + rate) to reverse the compounding effect accurately.

Below is the comprehensive list of official standard and reduced VAT rates across all 27 EU member states, plus the United Kingdom, Norway, and Switzerland for 2026. Reduced rates generally apply to basic groceries, books, pharmaceuticals, hotel accommodation, and passenger transport.

Here are practical, worked examples showing how calculations operate in common commercial situations across Europe: Example 1 — Adding VAT in Germany: • Scenario: An IT consultancy in Berlin bills €500 net for technical support. • Applicable VAT rate: 19% standard German Mehrwertsteuer (Umsatzsteuer). • Calculation: €500 × (1 + 0.19) = €500 × 1.19 = €595.00 (gross). • VAT amount: €595.00 − €500.00 = €95.00. Example 2 — Removing VAT in France: • Scenario: A company receives an office furniture invoice showing a total gross of €240.00 including French TVA at 20%. • Calculation: €240.00 ÷ (1 + 0.20) = €240.00 ÷ 1.20 = €200.00 (net). • VAT amount: €240.00 − €200.00 = €40.00. Example 3 — Reduced rate in Spain: • Scenario: A business lunch receipt in Madrid totals €50.00 gross, subject to Spain's 10% reduced IVA for restaurants. • Calculation: €50.00 ÷ (1 + 0.10) = €50.00 ÷ 1.10 = €45.45 (net). • VAT amount: €50.00 − €45.45 = €4.55.
