Add: net × (1 + rate). Strip: gross ÷ (1 + rate). Example at 20%: €100 net → €120 gross; €120 gross → €100 net. Never subtract 20% from gross (€96 — wrong).
Pick a preset (UK 20%, EU 19%, India GST 18%/12%, UAE 5%, Switzerland 8.1%) or type any rate — the tool applies one flat rate with no country, reduced-rate, or digital-services (MOSS) logic. Confirm the correct legal rate yourself.
B2B cross-border sales within the EU shift VAT accounting to the buyer (0% charged, buyer self-assesses). The tool does not model reverse charge — run exempt sales at a 0% rate and keep both VAT numbers on file.
Use the EU VIES database for real-time validation. Invalid numbers mean you must charge your local rate — the calculator only computes, it cannot verify numbers.
