What it does

Add VAT to a net price or strip VAT from a gross price. Works with any VAT rate — UK 20%, EU, or custom. Free and mobile-friendly. Money math compounds: small percentage differences over years become large dollar differences.

Federal Reserve rate decisions, tax law changes, and inflation shifts all change the optimal answer year-over-year. The gap between “rough estimate” and “defensible number” is exactly where good tooling earns its keep — the math is reproducible, but knowing which inputs matter and what the result means is half the work.

Always cross-check calculator output against published sources (IRS.gov for taxes, FRED for rates, Bankrate for current product pricing). A common pitfall: comparing pre-tax to after-tax numbers without normalizing. Treat the tool’s output as a starting point and validate against authoritative sources for any consequential decision.

Example input & output

Input

Mode: Add VAT
Net amount: $100
VAT rate: 20%

Output

Net: $100.00
VAT: $20.00
Gross: $120.00

Removing VAT is not subtracting 20%: $120 gross at 20% backs out to $100 net (divide by 1.20), while $120 − 20% would wrongly give $96.

How to use it

  1. Pick the mode: add VAT to a net amount, or remove VAT from a gross amount.
  2. Enter the amount and the VAT/GST rate (UK 20, Germany 19, Australia GST 10, etc.).
  3. Read net, VAT, and gross side by side.
  4. Flip the mode to cross-check an invoice that only shows one of the figures.

How it works

Adding VAT: gross = net × (1 + rate). Removing VAT: net = gross ÷ (1 + rate) — division, never a percentage subtraction. The asymmetry exists because the VAT was computed on the net, so the gross contains 100% + rate of the net. At 20%, VAT is exactly 1/6 of the gross price, a handy mental check.

Common mistakes when using this tool

  • Subtracting the rate to remove VAT. The most common VAT arithmetic error in small-business books. $120 minus 20% is $96; the correct net is $100.
  • Applying the standard rate to everything. Most VAT systems have reduced and zero rates (food, books, children’s clothing vary by country). Check the rate class of the actual item.
  • Confusing VAT-inclusive and VAT-exclusive quotes. Consumer prices in VAT countries include tax by law; business-to-business quotes are usually net. Always confirm which one a number is before doing arithmetic on it.

When to use this tool

  • Writing invoices that must show net, VAT, and gross as separate lines.
  • Backing the VAT out of a tax-inclusive receipt for expense reports or bookkeeping.
  • Pricing products for VAT countries where displayed prices must include tax.
  • Quick checks against a supplier's invoice — does the VAT line match the stated rate?

When not to use it

  • US sales tax — same arithmetic but different conventions (tax-exclusive pricing, combined state + local rates); use the sales tax calculator.
  • VAT returns and reclaim filings — those need transaction-level records and the rules of your tax authority, not a single calculation.
  • Mixed-rate baskets (some items standard-rated, some reduced or zero-rated) — calculate each rate class separately.

Common use cases

  • Freelancer in the UK adding 20% VAT to a £1,500 net quote before sending the invoice.
  • Accountant extracting the VAT from a €119 tax-inclusive receipt at the 19% German rate.
  • Shop owner pricing a product at a round gross figure and needing the implied net for the books.
  • Comparing a 'VAT included' price abroad against a pre-tax US price for the same product.

Frequently asked questions

How do I remove VAT from a price?
Divide by (1 + rate), don't subtract the percentage. A £120 price at 20% VAT: £120 ÷ 1.20 = £100 net, £20 VAT. Subtracting 20% from £120 gives £96 — wrong, because the 20% was charged on the net (£100), not the gross (£120).
What are typical VAT/GST rates around the world?
Standard rates: UK 20%, Ireland 23%, Germany 19%, France 20%, Hungary 27% (EU's highest), Australia GST 10%, New Zealand 15%, Canada GST 5% (plus provincial taxes), Japan 10%, UAE 5%. Most systems add reduced rates for essentials — UK charges 5% on home energy and 0% on most food. Rates change with budgets, so verify against the tax authority for filings.
What's the difference between VAT and sales tax?
Economically similar for the final consumer; mechanically different. VAT is collected at every stage of the supply chain, with each business reclaiming the VAT it paid on inputs — the consumer bears the final total. US sales tax is collected once, at the retail sale. Practical difference for shoppers: VAT-country shelf prices include the tax; US shelf prices don't.
Do I need to charge VAT as a small business?
Only above your country's registration threshold — in the UK that's £90,000 of taxable turnover in a rolling 12 months; many EU countries set thresholds far lower, and some require registration from the first sale for foreign sellers. Below the threshold, registering voluntarily can still pay off if you buy a lot of VAT-bearing inputs and your customers are VAT-registered businesses.
Can tourists reclaim VAT on purchases?
In many countries, yes — non-resident visitors can reclaim VAT on goods they export, via refund schemes at the airport (minimum purchase amounts and paperwork apply, and processors take a cut of the refund). Notable exception: the UK abolished its tourist VAT refund scheme in 2021. Services (hotels, meals) are generally not reclaimable anywhere.
