VAT Calculator

Add or remove VAT from a price.

Finance & MoneyUpdated 2026-04-05Author: CalcDock Team, Tax reference editorReviewed by: CalcDock Team, Editorial review: VAT add/remove formulas, jurisdictional disclaimers (Apr 2026)

The VAT Calculator handles both directions of VAT calculation: adding VAT to a net (ex-VAT) price to find the gross price, and removing VAT from a gross (VAT-inclusive) price to find the net price. Enter your amount and set the VAT rate for your country — common rates include 20% in the UK, 19% in Germany, 23% in Poland, 25% in Norway, 10% in Korea (부가가치세), and 10% in Japan (消費税). The tool is used by businesses for invoice preparation, by consumers for understanding the tax component in a listed price, and for inter-country price comparison. VAT applies at each stage of the supply chain in most countries, but the consumer ultimately bears the full tax — making the add/remove calculation essential for accurate pricing.

When this calculator helps most

Use when you know the legal VAT rate for your transaction and need a correct gross-from-net or net-from-gross split — for quotes, expense reports, or checking a receipt.

What each input means

  • Net price (ex-VAT)Amount before VAT when adding tax; leave blank if you only know the gross. (your currency)
  • Gross price (VAT-inclusive)Total including VAT when backing out tax; divide by (1 + rate) to find net. (your currency)
  • VAT ratePercentage set by law for your jurisdiction and product category. (%)

Input mistakes to avoid

  • Removing VAT: divide gross by (1 + rate), never subtract rate × gross.
  • Confirm whether displayed prices are tax-inclusive (common in EU/JP) vs tax-exclusive.
  • Use the rate in force on the invoice date, not an outdated blog post.

Formula

Add VAT: Gross = Net × (1 + rate ÷ 100) | Remove VAT: Net = Gross ÷ (1 + rate ÷ 100) | VAT amount = Gross − Net

Examples

Add 10% Korean VAT to ₩500,000 Invoice

B2B invoice in Korea — finding the VAT-inclusive total.

VAT (부가가치세): ₩50,000 | Gross total: ₩550,000

Remove 20% UK VAT from £1,200 Gross Price

Consumer product — extracting the pre-VAT price from the listed price.

Net (ex-VAT): £1,000 | VAT contained: £200 | Note: £1,200 ÷ 1.20, not £1,200 − (£1,200 × 0.20)

Add 19% German VAT to €850 Product Price

European product pricing — adding standard German VAT.

VAT: €161.50 | Gross: €1,011.50

Japanese Consumption Tax — ¥3,000 at 10% and 8%

Comparing standard (10%) and food reduced rate (8%) in Japan.

At 10%: Tax ¥300, Total ¥3,300 | At 8% (food rate): Tax ¥240, Total ¥3,240

UK 20% VAT — Net £120 → Gross?

Add VAT to a net price.

Gross = £144 | VAT = £24

Japan 10% 消費税 — 総額 ¥3,300 から税抜き

Remove VAT from a tax-inclusive price.

Net ≈ ¥3,000 | Tax ≈ ¥300 | 3,300 ÷ 1.10 = 3,000

How to read your results

  • Adding VAT: gross = net × (1 + rate/100); the tax portion is gross − net.
  • Removing VAT: net = gross ÷ (1 + rate/100); do not subtract rate × gross.
  • Reduced rates and exemptions (food, books, exports) can apply — verify category rules.
  • Cross-border B2B may use reverse charge; consumer purchases usually follow local standard rates.

What this result means

Outputs split an amount into net and VAT portions at the rate you entered — they do not determine tax liability; your jurisdiction’s rules do.

Common Pitfalls

  • ⚠️Removing VAT by subtracting the rate from a gross total — always divide by (1 + rate).
  • ⚠️Ignoring reduced/exempt items — check category‑specific rules.
  • ⚠️Using outdated rates — verify current VAT before invoicing.

Tips

  • When removing VAT from a gross price, always divide by (1 + rate), not subtract the percentage — the common mistake overstates the net price.
  • Korea's VAT is often included in listed prices. Look for "VAT included" (VAT 포함) or "VAT excluded" (VAT 별도) on quotes and invoices.
  • Japanese restaurants and shops often display both the pre-tax and tax-inclusive price — use this calculator to verify the tax amount.
  • For EU B2B transactions, check whether reverse charge rules apply — in many cases, the buyer accounts for VAT, not the seller.
  • Always verify current VAT rates before invoicing — rates change, and some items qualify for reduced rates not shown here.

How to check your results

  • Cross-multiply: net × (1 + r) should equal gross when adding VAT.
  • For 20% VAT, gross ÷ 1.2 yields net; mentally verify with round numbers first.

Warnings & Limitations

  • ⚠️VAT rates and rules change frequently and vary by country and product category — verify with official sources before invoicing.
  • ⚠️Some transactions use reverse charge or zero‑rating — check your specific scenario.

What this calculator does not tell you

  • Whether your product is zero-rated, exempt, or subject to a reduced rate — you must pick the correct rate.
  • Cross-border VAT, reverse charge, or import VAT rules.
  • Rounding rules mandated by your tax authority for invoice line items.
  • Currency conversion for international invoices.
