Basic
What it is & how to use it
VAT (value-added tax) calculators add tax to a net amount or extract tax from a gross amount at a rate you enter for your jurisdiction.
How to use the VAT Calculator
1) Enter the amount.
2) Enter the VAT rate % that applies where you sell.
3) Choose add vs extract as the tool UI allows.
4) Verify against your local rules before invoicing.

Formula & worked example
Gross = Net × (1 + rate/100). VAT amount = Gross − Net.
From gross: Net = Gross ÷ (1 + rate/100).
Example: $100 net at 20% → $120 gross, $20 VAT.

Interpretation, edge cases & next steps
Rates and rules differ by country and product type.
Advanced: do not mix inclusive and exclusive prices in the same margin calc; confirm exemptions separately.
Not tax advice — verify with a professional when stakes are high.
