How does VAT calculation work?
Example: 21% VAT
You have an amount of €121.00 including 21% VAT:
Formula:
BTW = (€121,00 / 121) × 21 = €21,00
Excl. VAT: €121,00 - €21,00 = €100,00
Example: 9% VAT
You have an amount of €109.00 including 9% VAT:
Formula:
BTW = (€109,00 / 109) × 9 = €9,00
Excl. VAT: €109,00 - €9,00 = €100,00
General Formula
VAT = (amount incl. VAT / (100 + rate)) × rate
Excl. VAT = amount incl. VAT − VAT
For 21%: divide by 121, multiply by 21. For 9%: divide by 109, multiply by 9.
Frequently Asked Questions
What is VAT?
VAT (Value Added Tax) is a consumption tax levied on goods and services. It is used in over 160 countries worldwide, including all EU member states. The Dutch term for VAT is BTW (Belasting over de Toegevoegde Waarde).
How do I reverse-calculate VAT from an inclusive amount?
To reverse-calculate VAT, divide the inclusive amount by (100 + the VAT rate) and multiply by the VAT rate. For example, for 21% VAT: VAT = (amount / 121) × 21. The amount excluding VAT is the inclusive amount minus the VAT.
What are common VAT rates?
VAT rates vary by country. Common rates include 21% (Netherlands, Belgium), 20% (UK, France), 19% (Germany), 25% (Sweden, Denmark), and reduced rates like 9%, 7%, or 5% for essential goods. Use the custom rate input to calculate for any percentage.
What is the formula for calculating VAT?
To add VAT: VAT = amount × (rate / 100). To reverse-calculate VAT from an inclusive amount: VAT = (inclusive amount / (100 + rate)) × rate. For a 20% rate, this simplifies to: VAT = inclusive amount × (20/120).
When do I need to calculate VAT?
VAT calculation is useful when you have a receipt or invoice and need to know the net amount and VAT portion separately — for example, for bookkeeping, tax returns, expense claims, or pricing decisions.
