VAT Calculator
VAT (VAT/IVA/TVA in EU) is a hidden tax in the price you pay. Shops often show "€50" but that already includes VAT. This calculator lets you choose: add VAT to a net amount, or extract the hidden tax from a gross price. Handy for invoicing and budgeting.

よくある間違い
- Adding VAT instead of extracting: you get 121% instead of EUR 121.
- Using the wrong rate: rates vary by country and product category.
- Forgetting VAT is already in shop price: you always pay the gross amount.
活用シーン
- Invoicing: Calculate how much net to invoice to achieve a certain gross amount.
- Shopping: Extract how much you really pay net when you see a shop price.
- Budgeting: Know how much of your amount goes to tax.
よくある質問
Why is VAT hidden in the price?
In most European countries, shops must show the total price including VAT. So the "€100" you see already includes tax. This differs from some other countries where VAT is shown separately. As a business, you only pay VAT on your net income, not the total.
