A GST calculator — or VAT calculator, or sales tax calculator, depending on where you live — tells you exactly how much consumption tax is baked into a price, in either direction. NeftCal's version handles all three under one tool across 12 countries and jurisdictions: an India GST calculator with a full CGST/SGST/IGST split, a UK VAT calculator and EU VAT calculators for Germany (MwSt), France (TVA), plus GST calculators for Australia, New Zealand, Singapore and Canada (GST/HST), VAT calculators for the UAE and Saudi Arabia, a US sales tax calculator, and a custom tax rate option for anywhere else. You can add tax to a tax-exclusive base price or remove tax from a tax-inclusive price — both directions, instantly.
Consumption tax rules differ enough between countries that a single flat percentage assumption gets people into trouble. A UK shelf price already includes 20% VAT; a US price tag typically doesn't include sales tax at all; an Indian invoice needs to show CGST and SGST separately for an in-state sale but a single IGST line for an inter-state one. This GST/VAT/sales tax calculator handles the arithmetic and the presentation for each of these cases so you don't have to keep multiple spreadsheets or memorize which country does what.
Freelancers and small business owners invoicing clients across borders, e-commerce sellers pricing products for multiple markets, shoppers double-checking a receipt or an online price, accountants and bookkeepers reconciling tax-inclusive figures, and students or new business owners learning how GST/VAT/sales tax actually gets applied in practice.
Getting tax-inclusive versus tax-exclusive pricing wrong doesn't just cause an embarrassing invoice correction — it can understate your revenue, overstate your margin, or leave you charging (or paying) the wrong amount entirely. For businesses approaching a registration threshold, knowing your true tax-exclusive turnover matters for compliance timing. For cross-border sellers, correctly separating CGST/SGST from IGST, or applying the right EU VAT rate for a digital service, affects both your paperwork and your legal exposure. A quick, reliable calculator removes the guesswork from what is otherwise a common source of pricing and invoicing errors.

From country selection to a full tax breakdown in under a minute
Select the country whose tax system applies — India, Australia, New Zealand, Singapore, UK, Germany, France, UAE, Saudi Arabia, Canada, US, or Other for a custom rate.
Pick Add Tax if you have a tax-exclusive base price, or Remove Tax if you have a price that already includes tax. US sales tax only supports Add Tax mode.
Type in the base price (Add Tax mode) or the total price (Remove Tax mode) in your selected currency.
Choose the applicable rate from the country's preset slabs, or enter a custom percentage for the US or any uncovered jurisdiction.
For India, also choose intra-state or inter-state to see the CGST+SGST or IGST split, then review the full breakdown, price chart, and rate comparison chart.
A step-by-step intra-state GST invoice calculation using this calculator's own default values
A freelance consultant in Maharashtra bills a client also based in Maharashtra (an intra-state, same-state transaction) for services worth ₹10,000 before tax, at the standard 18% GST rate.
Inter-state comparison: If the same client were based in a different state, the transaction would be inter-state — the full ₹1,800 would be charged as a single IGST line instead of splitting into CGST + SGST. The total tax and the final invoice value (₹11,800) stay exactly the same either way; only which government collects what, and how it's itemized on the invoice, changes.
Remove-tax example (UK VAT): Suppose a UK receipt shows a VAT-inclusive total of £120 at the 20% standard rate. Net price = £120 × 100 ÷ 120 = £100. VAT amount = £120 − £100 = £20. This is the calculation this tool performs automatically in Remove Tax mode for the UK, or any of the other 11 supported countries.
How the tax portion of a price compares across typical rate bands
The tax amount as a share of the total price is a useful way to sanity-check a result — it should roughly match the rate slab you selected. The bands below are general reference points across the countries this calculator supports, not an official benchmark from any single tax authority.
| Tax as % of Total Price | General Read | Typical Context |
|---|---|---|
| 0% – 5% | Low / reduced-rate tier | Essentials, zero-rated exports, UAE standard rate, UK/EU reduced categories |
| 6% – 15% | Mid-tier or reduced-standard rate | Australia/NZ/Singapore/Canada GST, many EU intermediate rates |
| 16% and above | Standard or luxury rate | UK/EU/India standard rates (18–23%), India's 28% luxury GST slab |
For sellers and freelancers: if your tax-inclusive quote doesn't line up with the base price plus the expected rate, double-check whether you accidentally applied the rate to the wrong base (a common error when re-quoting a price that already includes tax).
For shoppers and expense reporting: a large gap between the tax-inclusive and tax-exclusive figures on an unfamiliar receipt is worth double-checking against the country's published standard rate — it may signal a reduced-rate or zero-rated item, or occasionally a billing error.
Cross-border context: because US sales tax is added at checkout and not shown on shelf prices, while GST/VAT is baked into the sticker price almost everywhere else, comparing "the same" advertised price across countries without adjusting for this difference can be misleading.
