VAT Calculator
Add or remove VAT from a price.
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 rate — Percentage 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- •Use the rate in force on the invoice date, not an outdated blog post.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
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.
