Goods and Services Tax (GST), Value Added Tax (VAT), and Sales Tax are consumption taxes applied to the sale of goods and services. This calculator handles two directions: adding tax to a pre-tax price (exclusive), or extracting the tax component from a tax-inclusive price.
Tax-exclusive (adding tax): Tax amount = Price × (Rate ÷ 100). Final price = Price + Tax.
Tax-inclusive (extracting tax): Tax amount = Price − (Price ÷ (1 + Rate ÷ 100)). Pre-tax price = Price ÷ (1 + Rate ÷ 100).
Standard rates vary by country: India 18% (standard GST), Australia 10%, UK 20%, most EU countries 20–25%, Scandinavia 25%, USA has no federal sales tax (varies 0–10% by state). The calculator includes presets for 19 countries. Always verify the applicable rate for your specific goods or service category — many countries apply reduced rates to essentials like food, medicine, and children's clothing.
GST-exclusive pricing shows the base price before tax — the tax is added on top. GST-inclusive pricing means the tax is already embedded in the displayed price. When comparing prices, always confirm which format is being used.
To add GST: multiply the base price by (1 + rate/100). To find the tax amount from a GST-inclusive price: subtract (price ÷ (1 + rate/100)) from the total price. For example, 18% GST on ₹1,000: tax = ₹1,000 × 0.18 = ₹180; total = ₹1,180.
India: 5%, 12%, 18%, 28% (slab-based). Australia: 10%. UK: 20%. Germany: 19%. France: 20%. Sweden/Norway/Denmark: 25%. Canada: 5% federal GST + provincial. USA: no federal VAT; state sales tax varies 0–10%.
No. Most countries exempt or apply reduced rates to basic necessities such as unprocessed food, medicines, educational services, and healthcare. Always check the applicable rate for your specific product or service category.
