How it works
VAT, GST, sales tax — same idea, different names
VAT (Value Added Tax): Europe, UK, Japan (called 消費税). Charged at each step of production but ultimately paid by the consumer.
GST (Goods and Services Tax): Australia, Canada, India, Singapore. Mechanically similar to VAT, just a different name. Some countries (Canada) layer a federal GST and provincial taxes (HST, PST).
Sales tax: USA. Charged only at the point of final sale, varies by state, county, and city. Some states have none (e.g., Oregon, New Hampshire); others stack multiple jurisdictions for total rates over 10%.
Two-direction calculation
Add VAT: when you have a net (pre-tax) price and need the gross (post-tax). Common when listing prices for B2B clients or quoting before tax. Formula: gross = net × (1 + rate/100).
Remove VAT: when you have a gross (post-tax) price and need to extract the net. Common for receipts, expense reports, or invoice line items. Formula: net = gross / (1 + rate/100).
Common error: subtracting the rate% from gross to get net (e.g., $110 − 10% = $99). That's wrong — the correct calc is $110 / 1.10 = $100. The 10% VAT is on the net, not on the gross.
When VAT is already included or not
Most consumer prices in Europe, Japan, and Australia are tax-inclusive. The price tag is what you pay at the register; no extra at checkout. So a €10 product means €10 total.
Most US retail prices are tax-exclusive. A $10 sticker becomes $10.85 after California's 8.5% sales tax. Restaurants, online stores, and B2B invoices often vary.
B2B invoices typically show net + VAT separately for input-tax-credit purposes. Businesses can reclaim VAT they paid on inputs against VAT they collected from customers.
Frequently asked questions
›Is VAT and consumption tax (消費税) the same?
Yes — Japan's 消費税 is the local name for VAT. Same mechanism: charged at each production stage, paid ultimately by the consumer. Standard rate 10%, reduced 8% for food and newspapers.
›Why does 'remove 10%' give a different answer than just dividing by 1.1?
Removing 10% is dividing by 1.10. Subtracting 10% (e.g., 110 − 10% = 99) is mathematically wrong because the 10% applied was on the net (100), not on the gross (110).
›Can I calculate multi-stage VAT?
Not in this tool — we handle single-rate scenarios. For B2B with reverse charge or zero-rated transactions, consult an accountant or specialized tax software.
›What's the lowest VAT rate?
Some countries have 0% rates on essential goods (UK reduced rate on children's clothes, Japan 0% on rent and tuition). Use the actual applicable rate for your transaction.
›What's the highest VAT?
Hungary at 27%. Most EU countries are 19-25%. Japan is comparatively low at 10%.
›Does this work for US sales tax?
Yes — input the combined state + local rate. US sales tax behaves like single-stage VAT in calculator terms. Use 'add' mode for typical US listing → checkout flow.
›What about VAT-exempt items?
Use 0% rate for fully exempt items. Note: 'exempt' and 'zero-rated' have legal differences in some jurisdictions but the same calculator outcome.
›Does the data leave my browser?
No. Calculation runs locally; nothing is sent to a server.
